Evidence of Limited Laboratory Infection of Culex Tarsalis (Diptera: Culicidae) by Usutu Virus

Byers, NM, et al. Evidence of Limited Laboratory Infection of Culex Tarsalis (Diptera: Culicidae) by Usutu Virus. VECTOR-BORNE AND ZOONOTIC DISEASES Volume 00, Number 00, 2024. DOI: 10.1089/vbz.2024.0054

Abstract
Background: Usutu virus (USUV) is an emerging flavivirus, closely related to West Nile virus (WNV), that has spread into Europe from Africa. Since Culex tarsalis Coquillett is an important vector for WNV transmission in the United States, we tested the ability of USUV to replicate in and be transmitted by these mosquitoes. Materials and Methods: USUV was used to infect 3-4 day-old Cx. tarsalis with 5.6 to 7.5 log10 pfu/ml in goose bloodmeals. Saliva, heads, and bodies were collected on day 13 or 14 and analyzed by RT-qPCR for detection for USUV vRNA. Blotting paper punches were also collected daily to assess viral transmissibility. Results: The low and high dose blood meal resulted in 0% and 19.6% of the mosquitoes having established infections, respectively. All of the high dose had a dissemination of USUV RNA to the heads and none of the filter papers had detectable USUV RNA, but five of the capillary saliva collections were positive, representing 45.5% of the infected mosquitoes. Conclusions: Limited infection of Cx. tarsalis was observed when exposed to bloodmeals with greater than 10^7 pfu/mL of USUV, indicating this vector is not likely to have a key role in transmission of the virus.

Note: USUV is in the same Japanese encephalitis complex within the family Flaviviridae as WNV and SLEV. Cx. tarsalis is considered a potential vector of JEV based on vector competence studies [Reeves & Hammon. 1946. J. Exp. Med. 83: 185]. Because USUV causes extensive mortality in blackbirds, it is possible that mosquitoes could be exposed to higher blood meal titers in nature than used in these experiments. Also useful to remember that Cx. tarsalis is less suseptible to WNV than SLEV, and yet WNV is more prevalent because of its higher titers in infected avian hosts.

DENGUE/DHF UPDATE (91): AMERICAS, PAHO/WHO

A ProMED-mail post http://www.promedmail.org ProMED-mail is a program of the International Society for Infectious Diseases http://www.isid.org Date: Mon 7 Oct 2024 Source: PAHO/WHO Epidemiological Alert [edited] https://www.paho.org/en/documents/epidemiological-alert-increase-dengue-cases-americas-region-7-october-2024

Due to the increase in dengue cases reported by countries of the Central American Isthmus and Mexico during 2024 and considering the beginning of the dengue season in South America, the Pan American Health Organization/World Health Organization (PAHO/WHO) encourages Member States to continue their efforts in surveillance, early diagnosis, and timely care of dengue and other arbovirus cases, in order to prevent severe cases and deaths associated with these diseases, and, especially for countries in South America, to review their dengue response plans.

Summary of the situation in the Americas Region

———————————————–

In the Americas Region, the number of dengue cases recorded during the first half of 2024 exceeded the number of cases historically reported in a year, as compared to all previously recorded years. As of epidemiological week (EW) 36 of 2024, 47 countries and territories in the Americas Region have reported 11 732 921 dengue cases; this number is 2.5 times as high as the number of cases recorded throughout 2023, which was 4 594 823 dengue cases (Figure 1 [for all figures, see source URL]) (1). Between EW 1 and EW 36 of 2024, of the total reported dengue cases, 6 253 754 (53%) were laboratory confirmed. Of this total, 17 610 were characterized as severe dengue (0.15%) and 6650 fatal cases were recorded (case fatality rate of 0.057%) (1). Cases from 6 countries make up 97% of the fatal dengue cases in the Americas Region: Brazil with 5303 (82.4%), Argentina with 408 (6.1%), Peru with 234 (3.5%), Colombia with 131 (1.97%), Paraguay with 121 (1.8%), and Ecuador with 59 (0.88%) fatal dengue cases (1). All 4 serotypes of the dengue virus have been circulating in the Americas Region as of EW 36 of 2024. Brazil, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, and Panama report simultaneous circulation of the 4 serotypes (DENV-1, DENV-2, DENV-3, and DENV-4). Additionally, Argentina, French Guiana, Peru, and Puerto Rico reported simultaneous circulation of DENV-1, DENV-2, and DENV-3 (1). Note: The rest of the posting provides regional data for Mexico, Central and South American countries, all of which have marked increases in cases this year. The medical situation is complicated further by the circulation of all 4 strains of DENV which when contracted serially can lead to serious hemorrhagic disease complications.

Evaluation of landscaping and vegetation management to suppress host-seeking Ixodes scapularis (Ixodida: Ixodidae) nymphs on residential properties in Connecticut, USA

MA Linske, SC Williams. 2024. Evaluation of landscaping and vegetation management to suppress host-seeking Ixodes scapularis (Ixodida: Ixodidae) nymphs on residential properties in Connecticut, USA. Environmental Entomology, 53(2), 268–276.

https://doi.org/10.1093/ee/nvae007

Abstract [shortened]: Prior studies established that I. scapularis can be found in greatest abundance in the 1-m forested ecotone surrounding the lawn edge in residential backyards. Our study was conducted on 42 properties in Guilford, CT, and sought to expand upon this premise by determining which key habitat features were associated with increased densities of host-seeking I. scapularis nymphs. We quantified nymphal abundances in 19 different habitat types that were posited to in- fluence densities. We determined that nymphal I. scapularis densities were greatest in forested areas closest to lawn edges with leaf litter or understory vegetation present, as well as short lawns adjacent to woodland edges. Additionally, we determined that there were no significant declines in nymphal I. scapularis density where leaf litter was removed, lawns were left unmowed, or woodchip barriers were installed. Bird feeders and woodpiles were not associated with increased nymphal I. scapularis densities. However, areas adjacent to stone walls did have nearly 3 times the density of I. scapularis nymphs present compared with habitats without stone walls. The culmination of the results from this study can be utilized to create more targeted acaricide applications rather than broadcast spraying, as well as increase homeowner awareness for areas with heightened risk for exposure to nymphal I. scapularis, which are deemed the most epidemiologically important species and stage for pathogen transfer to humans. Note: Patterns for I. pacificus that frequently utilize lizards as hosts may be somewhat different.

NEW WORLD SCREWWORM – PANAMA (02): CATTLE, HUMAN

A ProMED-mail post

Panama warns of new outbreak of screwworm epidemic

————————————————–

Panamanian authorities have warned of a new epidemic the country is currently facing with cases of the cattle screwworm which also affects humans.

In statements to Prensa Latina, Carlos Moreno, from the Panama-United States Commission for the Eradication of the Screwworm (COPEG) specified the rise of the plague in mid-2023 was due to the lack of vigilance by both citizens and authorities during the COVID-19 pandemic.

In addition, he explained, the increase in cases, some 27 330 from 2022 to date, was due to other factors such as climate change, movement control, and greater awareness among the population.

The screwworm is not only affecting livestock; humans and other animal species are also being harmed.

In Panama, the Ministry of Health (MINSA) has recorded some 79 cases, according to epidemiologist Damaris Contreras, who called on people not to treat wounds at home but to go to health centers or hospitals.

The screwworm, which is laid by the fly _Cochliomyia hominivorax_, feeds on the living tissue of animals and can be fatal if not treated properly. This fly seeks to lay its eggs in “fresh wounds” of any type of warm-blooded animal. In a single wound, this fly can lay between 150 and 300 eggs, explained Lester Reyes, from Animal Health Epidemiology at the Ministry of Agricultural Development (MIDA). Once the larvae develop, they leave the wound and drop to the ground, where they bury themselves until they reach the pupal stage and thenbecome adult flies. Therefore, when healing these wounds, the maggots must be removed and eliminated immediately, because if they are left alive they turn into flies.

Panama has the only plant for the production of sterile flies which counteract the reproduction of flies laying the eggs of the screwworm. Specifically, the impact is occurring in other countries has led Panama to suspend the distribution of sterile flies, said Reynaldo Vivero, from MIDA, who also explained sterile flies are not being distributed in the country, since they are being sent to other countries to control the outbreak.

See attached for additional postings, comment and information.

Communicated by: ProMED

Note: The screwworm fly historically was endemic in the USA and was eradicated by the first SIT program. The fly eventually was pushed south of Mexico, with Panama being the southern border maintained by surveillance and further fly releases. Panama has the only remaining sterile fly production facility. The fly is still endemic in parts of South America. Northern dispersal, if not immediately contained, would require a large scale eradication effort that would be very costly.

DENGUE/DHF UPDATE (87): USA (CALIFORNIA) MORE TRANSMISSION

A ProMED-mail post http://www.promedmail.org

Date: Thu 3 Oct 2024

Source: KOST [edited] https://kost1035.iheart.com/featured/la-local-news/content/2024-10-03-5th-locally-acquired-dengue-case-confirmed-in-la-county/

Los Angeles County health officials Thursday [3 Oct 2024] continue to investigate a 5th locally acquired case of the mosquito-borne illness dengue, this time in a resident of El Monte. The latest patient does not appear to have any connection with the 4 previous reported infections, the county Department of Public Health said Wednesday [2 Oct 2024].

Health officials again stressed that locally acquired cases of dengue are extremely rare in areas where it has not been previously transmitted by mosquitoes. The county previously reported a cluster of 3 infections in the Baldwin Park area, and last week a 4th case was confirmed in a Panorama City resident. Health officials called the spate of local cases “unprecedented.”

None of the local patients had any history of travel to areas where dengue is endemic. In October and November of last year [2023], single locally acquired cases of dengue were confirmed by health officials in Pasadena and Long Beach.

Health officials noted that the symptoms of dengue often mirror those of other viruses, and they urged health-care providers to be “vigilant for dengue fever in patients with acute febrile illness and test for and report such cases of mosquito-borne diseases.”

— Communicated by: ProMED

FROM PROMED [It is interesting to note that the latest patient does not appear to have any connection with the 4 previous reported infections. There is a previously reported cluster of 3 cases in the Baldwin Park area, a single case in Panama City and now the latest one in El Monte. One wonders if there are several other dengue virus infected individuals in these 3 localities that have asymptomatic or very mild infections that have not resulted in medical attention so are not reported.

The above report does not indicate which vector mosquito was likely involved in dengue virus transmission in the 3 localities. As noted in the previously posted comment, the mosquitoes most likely involved are _Aedes aegypti_ or _Aedes albopictus_, both of which have been detected in California over the past 20 years. The preventive measures to avoid ongoing transmission are avoidance of mosquito bites and reduction of the mosquito populations. Mosquito control districts are undoubtedly attempting to control these vector mosquitoes, but that is a difficult task and requires collaboration with local residents to eliminate the water catchments in which these mosquitoes breed around their homes and other buildings.

Note that both _Aedes aegypti_ and _Aedes albopictus_ have been found in Los Angeles County. Which of these transmitted dengue virus to the residents is unknown. Locally acquired dengue virus infections remain extremely rare in California but occurrence of this cluster of cases indicates that local acquisition of dengue virus can occur. – Mod.TY

Note: The juxtaposition of these cases to the primary or imported cases has not been reported. As indicated above, it would seem that potentially other perhaps milder secondary cases have gone unnoticed, although these could still be a source of virus for mosquito infection making a vector control response difficult to focus geographically.

Dead Bird Call Center Season Ending October 11th

The West Nile Virus and Dead Bird Call Center will transition to accepting internet reports only for the winter season on Friday, October 11th, at 12 pm. That day will mark the end of the WNV dead bird testing season for 2024. To date this year, approximately 5,488 dead birds have been reported, 1,578 have been tested, and 458 have tested positive for WNV.

Winter protocol: Beginning in the afternoon of October 11th, those calling to report a dead bird will hear a message encouraging them to visit westnile.ca.gov to fill out an online report. Online reporters will receive an appropriate automatic email response with carcass disposal advice, how to contact their local VCD, or instructions for further action if the bird is suitable and the local agency is testing. We will review each internet report and follow up as necessary.

Testing by RNASound cards: For the agencies with continued winter WNV dead bird testing who do not test in-house, RNASound cards may continue to be shipped to DART (UC Davis Arbovirus Research and Training Laboratory). Turnaround time will be longer, however, and there will be some periods of closure around major holidays.

DENGUE/DHF UPDATE (80): USA (CALIFORNIA) LOCALLY ACQUIRED

A ProMED-mail post
Date: Tue 17 Sep 2024 17:05 EDT
Source: Newswise [edited]

Amid southern California’s recent record-breaking heat wave and fast-moving wildfires, public health officials reported the third locally acquired case of dengue fever in the Los Angeles area. Although the events seem unrelated, they actually are connected — and for troubling reasons. Communicated by: ProMED “”This is the third locally acquired dengue case in the Los Angeles, California area this year (2024). This resident was bitten by a dengue virus-infected mosquito, most likely _Aedes aegypti_ or _Aedes albopictus_, both of which have been detected in California over the past 20 years. The question with all these locally acquired infections is: where, when and from whom did the vector take the infectious blood meal? Did that infected individual acquire their dengue infection locally or in a dengue-endemic country and subsequently traveled to Los Angeles County, California while viremic? The risk of ongoing transmission depends on the presence of vector mosquitoes. There are 24 counties in California in which _Aedes aegypti_ and _Aedes albopictus_ have been found over the past 20 years.”

GROUND-BASED PYRETHROID ADULTICIDES REDUCE MOSQUITOES BUT NOT NONTARGET INSECTS IN CENTRAL FLORIDA

GROUND-BASED PYRETHROID ADULTICIDES REDUCE MOSQUITOES BUT NOT NONTARGET INSECTS IN CENTRAL FLORIDA. Hart, JD, et al. 2024. Journal of the American Mosquito Control Association, 40(3):125–136, 2024.

ABSTRACT. As stewards of public and environmental health, mosquito control agencies are rightfully concerned about [treatment] impacts on nontarget organisms. This study examined the impact of a modern, pyrethroid based ground adulticide program using ultra-low volume applications in a metropolitan county in central Florida. Nontarget insects and mosquitoes were collected in a before-after control-impact design at 21 sites over 1.5 years. While mosquitoes were reduced, we found no evidence for reduction of nontarget insects, regardless of taxon. Night-flying Lepidoptera may experience greater risk than other nontarget taxa, but overall effects of adulticide missions on this group were low and inconsistent. Instead, meteorology, habitat, and phenology dominate patterns of nontarget abundance. Mosquito reduction was more clearly observed and corrected post-mission reduction was consistent with results expected in complex urban and suburban treatment zones.

Note: Interestingly this paper did not present results for Diptera groups closely related to mosquitoes such as the Chironomidae, but rather focused on larger-bodied groups such as the Calliphoridae. Regardless, the study seemed well-done and should provide useful information to support the application of adulticides.

Colorado tick fever in the United States

Colorado tick fever in the United States, 2013-2022. Fagre A., et al. Am. J. Trop. Med. Hyg., 111(3), 2024, pp. 598–602 doi:10.4269/ajtmh.24-0044

Abstract [condensed]. Colorado tick fever (CTF) virus is an arbovirus maintained in an enzootic cycle between Rocky Mountain wood ticks (Dermacentor andersoni) and rodent species in the western United States. Individuals with CTF typically present with symptoms including fever, headache, myalgia, and lethargy, with a biphasic illness frequently occurring. ‘Authors’ reviewed data on CTF cases reported to the national U.S. arboviral disease surveillance system and identified through testing at the CDC to characterize the epidemiology of CTF from 2013–2022. During this period, 148 CTF cases were identified, all likely infected in an endemic area in one of six states (Montana, Wyoming, Oregon, Colorado, Utah, Idaho). These findings substantiate the continued circulation of CTF virus in the western United States, highlighting the importance of implementing approaches to ensure CTF awareness for medical providers and providing education on tick bite prevention strategies for residents and visitors to risk areas.

Note: Although CTF cases have not be reported from California, the authors’ distribution maps show the presence of the principal vector D. andersoni in the Sierra, Tehachapi and northern Coast Ranges.

EASTERN EQUINE ENCEPALITIS – NORTH AMERICA (10): USA (NEW HAMPSHIRE) HUMAN, FATAL

A ProMED-mail post http://www.promedmail.org ProMED-mail is a program of the International Society for Infectious Diseases http://www.isid.org Date: Tue 27 Aug 2024

Source: New Hampshire Department of Health and Human Services [edited] https://www.dhhs.nh.gov/news-and-media/nh-dhhs-identifies-person-infected-eastern-equine-encephalitis-virus-new-hampshire

The New Hampshire Department of Health and Human Services (DHHS), Division of Public Health Services (DPHS) has identified an adult from Hampstead, New Hampshire who tested positive for Eastern Equine Encephalitis Virus (EEEV) infection, was hospitalized due to severe central nervous system disease, and has passed away due to the illness. DHHS offers our sympathies to the individual’s family and friends.

EEEV is a rare but serious disease transmitted to people by infected mosquitos. The last reported human EEEV infection in New Hampshire was in 2014, when DHHS identified 3 human infections, including 2 fatalities. In addition to the person with EEEV infection announced today [27 Aug 2024], EEEV has been detected in one horse and 7 mosquito batches in New Hampshire so far this summer. EEEV has also been detected in neighboring states, including in Massachusetts (one person, one horse, and 69 mosquito samples) and Vermont (one person and 47 mosquito samples).

Note: This article references a series of postings concerning EEEV activity in the NE USA. Increased EEEV combined with WNV activity has triggered evening curfews and widespread adulticide applications that have made the national news. EEEV in an Alphavirus within the family Togaviridae that is widely distributed east of the Mississippi River and throughout South America. In the eastern USA Culiseta melanura is the principal enzootic vector, with a series of Aedes, Coquillettidia and Culex species serving a bridge vectors. The virus is not found in California, although historically it was isolated from a deceased yearling horse with a travel history that died in San Bernardino during the spring of 2000.

Optimizing and synchronizing Aedes aegypti colony for Sterile Insect Technique application: Egg hatching, larval development, and adult emergence rate

Abstract

Mosquito Sterile Insect Technique (SIT) programs can be developed in smaller agencies through synchronization of the colony development to take advantage of the natural male early emergence. This paper examined key aspects of Ae. aegypti colony synchronization work, including egg hatching, larval development, and adult emergence to produce sufficient numbers of adult male mosquitoes within a specific timeframe for irradiation and release. Our data indicated that a relatively low percentage of males are required for colony propagation. Additional results highlighted that fresher Ae. aegypti eggs could yield as high as a 93 % hatching success than older eggs when placed under vacuum pressure in yeast infused water for 1.5 h. Eggs that were one-month old hatched (93 %) better than older eggs (0–32 %). A higher egg density in the hatching flask was correlated to a lower hatch rate, and higher larval density was related to unsynchronized pupae and delayed adult emergence. By keeping Ae. aegypti larvae at reasonable density, over 95 % of adults emerged on the first two days of emergence – indicating a high synchronicity. A standardized colony maintenance protocol therefore renders a synchronized larval development and adult male emergence which are critical in SIT programs.

MVCAC Statement on Eastern Equine Encephalitis

Eastern equine encephalitis is a serious disease that is transmitted to humans through the bite of an infected mosquito. It is prevalent on the East Coast and around the Great Lakes and has not been detected in California. According to the U.S. Centers for Disease Control and Prevention, human eastern equine encephalitis cases occur relatively infrequently, largely because the primary transmission cycle takes place in and around swampy areas where people are less likely to go.

An average of 11 human cases of eastern equine encephalitis are reported in the U.S. each year. As of August 27, 2024, the CDC reported four human cases, in Wisconsin, New Jersey, Massachusetts, and Vermont. In addition, officials in New Hampshire have reported one death.

California mosquito control experts are continuously monitoring for disease threats and working to protect public health. West Nile virus is the most prevalent and serious disease transmitted by mosquitoes in California. An important way to protect yourself and your family from mosquito bites is to apply insect repellent containing an EPA-registered active ingredient, including DEET, picaridin, oil of lemon eucalyptus, or IR3535, to clothes and exposed skin when spending time outside.

Preparation for targeted sterile insect technique to control invasive Aedes aegypti (Diptera: Culicidae) in southern California: dose-dependent response, survivorship, and competitiveness

Abstract

Aedes aegypti is fast spreading across California, with over 300 cities within 22 central and southern counties being infested since its introduction in 2013. Due to its cryptic breeding habitats, control efforts have not been successful so far. This calls for innovative tools such as sterile insect technique (SIT) to reinforce the existing integrated pest management (IPM). Here, we assessed fitness, survivorship, and dose response of X-ray irradiated male Ae. aegypti in California. Locally acquired Ae. aegypti eggs were hatched and reared in temperature-controlled laboratory setting at the West Valley Mosquito and Vector Control District in Ontario, California. Freshly emerged adult male mosquitoes were manually separated using motor-operated aspirators and treated with X-ray radiation at different dosage (42–60 Gy). Dose response of irradiated males was analyzed and induced sterility determined. Survivorship of males treated with different X-ray doses was compared. Fecundity of females that mated with irradiated males at different X-ray doses was generally comparable. Overall, induced sterility increased with higher X-ray doses. Nulliparous females that mated with male Ae. aegypti treated with 55–60 Gy laid eggs with over 99% sterility. Non-irradiated male mosquitoes had higher survivorship (mean = 0.78; P = 0.0331) than irradiated mosquitoes (mean range = 0.50–0.65). The competitiveness index of irradiated males decreased with increasing X-ray treatment doses, 1.14 at 55 Gy and 0.49 at 60 Gy, and this difference was significant (P < 0.01). Irradiated males showed high survivorship and competitiveness—key for the anticipated SIT application for the control of invasive Ae. aegypti in California.

OROPOUCHE VIRUS – USA: ex CUBA

OROPOUCHE VIRUS – USA: ex CUBA

A ProMED-mail post http://www.promedmail.org ProMED-mail is a program of the International Society for Infectious Diseases http://www.isid.org

Date: Mon 19 Aug 2024 16:00 CDT Source: Precision Vaccinations [edited] https://www.precisionvaccinations.com/2024/08/19/11-oropouche-fever-cases-diagnosed-florida

[Shortened] Throughout 2024, Cuba has been grappling with an outbreak of Oropouche fever. And now, its western neighbor, the United States, has started to report cases related to travelers from Cuba. The Florida Department of Health (FDH) has recently reported 11 Oropouche fever cases. As of August 10, 2024, these Florida cases had their onset in 2024 and were found in individuals who had traveled toCuba 2 weeks before showing symptoms.

Throughout 2024, more than 8000 Oropouche cases, including 2 deaths and 5 cases of vertical transmission, were reported by the US Centers for Disease Control and Prevention (CDC) [see https://www.cdc.gov/oropouche/about/index.html ].

According to the CDC, approximately 60% of people infected with the Oropouche virus become symptomatic. The incubation period is typically 3-10 days. Although people exposed to biting midges or mosquitoes infected with the virus are most at risk for developing the disease, the risk factors for more severe Oropouche virus are not well-defined. The initial clinical presentation is similar to diseases caused by dengue, Zika, and chikungunya viruses.

In the United States, healthcare providers should contact local health departments to facilitate diagnostic testing.

Note: See the rest of the ProMed post for additional details and links to other information. Oropouche virus is in the group Orthobunyavirus and is transmitted by Diptera in the family Ceratopogonidae. The reputed primary vector in South America, Culicoides paraensis, is not found in North America, but California has other Ceratopogonidae, including the vector of Blue Tongue virus, Culicoides sonorensis, and the painful biting ‘no-see-um’, Leptoconops torrens. These species have not been tested for vector competence for Oropouche. There have been isolations of this virus from Coquillettidia and Aedes mosquitoes, and there have been reports suggesting that Culex quinquefasciatus are involved in some urban transmission.

Diagnosis and Genomic Characterization of the Largest Western Equine Encephalitis Virus Outbreak in Uruguay During 2023–2024

Diagnosis and Genomic Characterization of the Largest Western Equine Encephalitis Virus Outbreak in Uruguay During 2023–2024. Tomas, G. et al. 2024, Research Square Preprint.

Abstract [shortened]. The most recent large outbreak of WEEV occurred in the Southern cone of South America from November 2023 to April 2024, affecting many equines and humans in Argentina and Uruguay. The virus affected 1,086 horses and caused 388 deaths in all regions of Uruguay. We obtained genomes from 15 strains using a novel multiplex PCR assay combined with next-generation Illumina sequencing. The phylogenetic analysis revealed that samples from Uruguay and Brazil collected during 2023–2024 and an Argentine strain from 1958 share a common evolutionary origin and are distinct from North American strains. Phylogenetic and epidemiological data on the outbreak suggest that it originated in Argentina and spread to Uruguay and Brazil, likely by movements of infected birds. Genomic analysis also revealed mispairing in real-time PCR primers and probes that may affect official diagnostic protocols, highlighting the need for assay updates. Our research emphasizes the need to map the genetic diversity of WEEV in South America to understand their epidemiology and develop effective control approaches.

Note: Although the WEEV strains isolated here differed from those historically found in North America, the recent introduction of SLEV strains found in California were most similar to historical isolates from Argentina, perhaps indicating a proven path for introduction. Comments concerning RT-PCR diagnosis were similar to minor problems CVEC encountered detecting WNV using the current RT-PCR probes and problems encountered developing the current WEEV probes.

MVCAC Annual Conference Hotel Scam

MVCAC has become aware of companies contacting our exhibitors and possibly our members, falsely claiming to be a housing bureau authorized to secure rooms at the Oakland Marriott where the MVCAC Annual Conference will be taking place next year. We want to remind you to book your conference hotel room only through the official MVCAC booking link.

These entities may offer rooms at purportedly discounted rates. Please be aware that these are unauthorized third-party entities without any affiliation with MVCAC or the Oakland Marriott. They have no authority to make reservations on behalf of attendees.

These companies may book rooms for you at fully prepaid rates with no option for cancellation or changes, and they offer no support if issues arise with your reservation. They are essentially poachers of hotel room blocks. 

The only legitimate way to reserve accommodations for any MVCAC event is through the booking link provided directly by us in partnership with the hotel. Reservations made through any other means will not be credited within our block and could potentially put us in an attrition risk.

We are actively monitoring this situation and urge you to inform us if you are contacted by such companies. Unfortunately, there is little recourse against their actions.

Booking through the official MVCAC booking link ensures both you and MVCAC are protected! Find the booking link here.

Duration of Fever in Patients with Dengue: A Systematic Review and Meta-Analysis

Duration of Fever in Patients with Dengue: A Systematic Review and Meta-Analysis. Gupta, N., et al. Am.J. Trop. Med. Hyg., 111(1), 2024, pp. 5–10. doi:10.4269/ajtmh.23-0542.

Abstract [Shortened]. There is a need to establish the average fever duration with a confidence interval among patients with dengue. Studies up to October 21, 2022 from two databases (PubMed and Embase) were included using the search terms related to dengue and duration of fever. Studies where the average duration of fever was available were included for systematic review. A total of 643 articles were included from the two databases after duplicate deletion. After two rounds of screening, 31 articles (n 57,905) were finally included. The mean duration of fever in the 20 articles included for meta-analysis was 5.1 (95% CI: 4.7–5.5) days. Longer duration of fever was seen in those with a higher grade of fever, those with higher disease severity, and those with concurrent bacterial infections.

Note: The is considerable overlap between the onset of febrile and viremia stages following dengue infection, especially as it relates to infectivity to mosquitoes [see ]. Most likely the onset of fever is the first indication of illness to the patient and may provide a ‘skeletal’ timeline for the 1st recognition of the onset of dengue viremia. As the time window is short, early detection and reporting are important for surveillance to detect infected Aedes and possible secondary infections.

Historical and Personal Reflections on Mosquito Ecology and Control

Phil Lounibos, PHD

Bio:

A sixth-generation Californian, Phil Lounibos grew up on a chicken farm in Petaluma. He attended the University of Notre Dame, where he was introduced to mosquito research in the lab of the late George Craig. After a PhD in biology at Harvard University, as a postdoctoral fellow at the Mosquito Biology Unit of the International  Centre for Insect Physiology and Ecology, he oversaw the first trials for genetic control of Aedes aegypti on the Kenya coast and performed independent research on other East African container mosquitoes. From 1977-2017, from the Florida Medical Entomology Laboratory he conducted in both Florida and South America ecological, behavioral, and physiological studies on a wide range of mosquito species. The ecology of invasive mosquito species, especially Ae. aegypti  and Aedes albopictus, and mechanisms of displacement and segregation, were major themes of his final two decades of research at FMEL, funded by NIH. Lounibos mentored numerous graduate students and postdocs as a faculty member of the University of Florida.

SB 1251 (Stern) Passed the Senate

SB 1251 (Stern), sponsored by MVCAC, passed the Senate almost unanimously and now goes on to the Assembly. SB 1251 would allow mosquito control districts to request a plan be filed with utility corporations for the purposes of entering into vector management agreements within 6 months of a request being sent. We will keep you posted on when the bill will be heard next.
