Voles populating Chino Hills

From Champion Newspapers
July 11, 2020

A spike in the vole population in Chino Hills and the region has prompted numerous calls to the city and the West Valley Mosquito and Vector Control District.

A vole is a rodent known as a “meadow mouse” that like to populate urban landscapes with grass and other cover they feed on, according to Janet Hartin, with the UC Cooperative Extension.

They like loose deep garden soil that makes it easier for them to burrow, she said. 

“Often, it’s the gardeners that seem to have the most trouble with them,” she said.

Kevin Marin, who has lived in Butterfield since 1991, said he has never seen so many voles, rodents, and rabbits.

‘Murder hornet’ mania: Hundreds of people think they’ve spotted the Asian giant hornet

From USA Today
July 10, 2020

Hundreds of people in Washington State have reported suspected “murder hornet” sightings in the months since the insect was first spotted in the U.S., stirring panic in a nation already reeling from the coronavirus outbreak.

But only five of those reports were bona fide Asian giant hornets, the 2-inch-long invasive species that slaughters honeybees and can be deadly to humans, according to the Washington State Department of Agriculture.

“Unfortunately, while their intentions are good, many people have killed and submitted many insects that are NOT Asian giant hornets,” entomologists Quin Baine and Chris Looney said in mid-June. “Not only are most of these insects not harmful, they play an important role in the environment.”

Zika May Have Damaged More Infants’ Brains Than Expected

From U.S. News and World Report
July 7, 2020

It’s a virus some might not even remember, but babies born to mothers infected with Zika who appeared normal at birth still experienced neurological or developmental problems, new research suggests.

A hallmark of infection with the mosquito-borne Zika virus in pregnant women is delivering a baby with an abnormally small head — a condition called microcephaly. But as children exposed to Zika in the womb are growing up, researchers are learning that it’s not only the youngsters born with microcephaly that they need to worry about.

Long Beach sees first case of West Nile virus this year

From the Long Beach Post
July 7, 2020

Public health officials are warning people to be vigilant during mosquito season after a patient in his or her 60s was diagnosed with West Nile virus in Long Beach this week, marking one of the first cases in Southern California so far this year.

“While the world is focused on COVID-19 prevention and response, this is an important reminder that we continue to see cases of West Nile Virus most years in Long Beach,” City Health Officer Dr. Anissa Davis said in a statement. “We cannot let our guard down against mosquito-borne diseases.”

The first cases were initially reported in Northern California this year.

No mosquitoes in Long Beach have been found to be positive for the virus thus far this season.

The virus is transmitted through the bite of an infected Culex mosquito and may include symptoms such as fever, body aches, rash, nausea, vomiting and headache. Most people who become infected have no symptoms.

New species of mosquito arrives in Kern County

From KGET
July 7, 2020

BAKERSFIELD, Calif. (KGET) — Kern Mosquito and Vector Control on Monday said mosquitoes trapped east of Arvin have tested positive for the West Nile virus.

Additionally, a species of mosquito that is new to Kern has arrived. Called the Aedes aegypti, it’s a tiny, aggressive bug that feeds multiple times, said Terry Knight of Vector Control.

No human cases of West Nile virus have been reported in Kern so far this year. Knight recommended wearing long-sleeve shirts and pants when outdoors, and draining any standing water near residences to stop them from breeding.

How British Columbia and Washington state are stopping the spread of Asian giant hornets

From The Conversation
July 7, 2020

Panic-stricken headlines about “murder hornets” are thankfully mostly behind us. The nickname may have staying power, but it is certainly unearned.

First spotted in British Columbia in August 2019, the Asian giant hornet (Vespa mandarinia) poses little threat to humans. In its native range in East Asia, the giant hornet is chiefly a menace to the livelihoods of beekeepers, provoking concern that it could cause similar problems in North America.

County health officials remind residents to take precautions against mosquitoes, West Nile virus

From KGET
July 5, 2020

BAKERSFIELD, Calif. (KGET) — County health officials are asking residents to safeguard their homes against possible breeding sites for mosquitoes and to protect themselves from the risk of acquiring the West Nile virus.

The best way to avoid the West Nile Virus, the county says, is to avoid mosquito bites, and reducing spots where they can breed.

Officials say residents should:

  • Remove standing or stagnate water from containers. Flowerpots, fountains, birdbaths, pet bowls, and other containers — even gardening tools and toys — can collect water.
  • Clean and scrub containers that collect water to remove eggs.
  • Maintain swimming pools in working condition.
  • If you have a garden pond, stock them with fish that eat mosquito larvae. You vector control district can provide free fish.
  • Report areas of mosquito infestation to your local vector control district.

July 3, 2020

Additional mosquitoes trapped in the Coachella Valley tested positive for West Nile virus, this time in Indian Wells, officials said Thursday.

The mosquitoes were collected from traps near Vintage Drive and Portola Avenue, according to the Coachella Valley Mosquito and Vector Control District

Indian Wells is the third Coachella Valley city where West Nile virus has been detected this year. In June, mosquitoes positive for the virus were reported in Palm Desert and Cathedral City.

This year, 21 mosquitoes have tested positive for the virus. The Coachella Valley has no reported human cases of West Nile, which is transmitted to people and animals through the bite of an infected mosquito.

“Impacts of COVID-19 on staff resulted in the District suspending services for two weeks so residents across the valley need to help us and protect themselves against mosquito bites,” said Tammy Gordon, a district spokeswoman. “Avoid spending time outdoors at dawn and dusk. If you have to be outdoors, wear long sleeves and apply bug spray.”

Can You Get Covid-19 From Mosquitos?

From Late Night Health
July 2, 2020

MVCAC President Peter Bonkrude joins Mark Alyn on Late Night Health to answer the question: “Can You Get Covid-19 From Mosquitos?”

Mosquito experts say the increased attention on public health is an excellent reminder that there are many ways for residents to protect themselves from mosquito-transmitted diseases.

According to the World Health Organization (WHO), to date, there is no data to suggest that COVID-19 is spread by mosquitoes. The U.S. Centers for Disease Control and Prevention says that the main way that COVID-19 spreads is from person to person.

While COVID-19 is not transmitted by mosquitoes, they can transmit several other diseases such as West Nile virus. There is no human vaccine for this disease which can cause debilitating cases of meningitis, encephalitis, and even death. Also, newly established invasive Aedes mosquitoes can transmit viruses such as chikungunya, dengue, and Zika, all of which are costly to treat and can have long-term health and financial consequences.

Brazil’s Tale Of Two Epidemics: Zika And COVID-19 – OpEd

From EurasiaReview
July 2, 2020

As Brazilian athletes were preparing for the upcoming Summer Olympics, a growing global health crisis shifted the government’s attention from winning gold medals to securing testing kits. On February 16th, the Brazilian government ordered the deployment of 220,000 soldiers to hand out educational material to citizens on how to combat the new virus that was ravaging the country, a strategy that proved effective in mitigating the spread of the disease. The year was 2016, and Zika virus was the disease.

Four years later, Brazil is losing the battle against a more formidable enemy, COVID-19. The country has the world’s second-highest death toll, having surpassed the United Kingdom as deaths reached 44,000. As the situation becomes grimmer by the day, President Jair Bolsonaro has chosen to replace his two previous health ministers with an army general to lead the country to battle, even though he lacks a background in public health or medicine. The president, himself a retired army captain who has fondly romanticized the military dictatorship that ruled Brazil from 1964 to 1985, has downplayed the pandemic, calling it a “little flu.” Thus far, Brazil’s COVID-19 response has been so botched that on May 26, President Donald Trump, long-time Bolsonaro ally, prohibited the entry of foreign Brazilian nationals into the United States due to an increased risk of transmission.

COVID-19 isn’t the only virus spreading this summer; entomologists watching spread of West Nile

From ABC 10 San Diego
July 1, 2020

Heather Hyland, a self-proclaimed bug nerd, has found a love for mosquitos despite the diseases they carry.

“I have loved bugs I would say since I was about 2 years old,” Hyland said.

Initially a public information officer for the Orange County Mosquito and Vector Control District in Southern California, she said her bug fascination was because so many people don’t like them. So, as a child, Hyland thought, someone should love them. That love turned into entomology.

“They’re so interesting. They’re these intricate little tiny bugs with the capability to do big things. If you look at how prehistoric a mosquito is, it has six mouth parts. There’s so many different things they can do that are big,” Hyland said.

‘Murder hornets’: race to protect North America’s honeybees from giant invader

From The Guardian
June 25, 2020

It took Moufida and John Holubeshen just a day of tracing alleged sightings and studying map coordinates before the two amateur detectives found their target.

“We did the whole CSI thing,” says Moufida. “Plotting points and drawing lines, searching for where the middle of the circle – the nest – would be.”

The couple, like hundreds of other beekeepers in western Canada and the US, were hunting the Asian giant hornet, an invasive species whose stealthy advance throughout British Columbia and Washington state is causing growing unease.

Scientists and apiarists fear that, if permitted to spread unchecked, the hornets, which feast on honeybee larvae, could have disastrous consequences for tens of thousands of hives.

Zika virus ‘harms baby brain collagen development’

From SciDevNet
June 25, 2020

Zika virus can hamper vital collagen development in the brains of babies whose mothers were infected with the disease while pregnant, new research reveals, as the search for a vaccine continues.

Collagen is crucial to the circulatory system, as it regulates the compression of blood vessels. A large amount of the collagen found in the human brain is located inside vein tissue.

The research findings could explain the deaths of babies with microcephaly, a birth defect that causes a baby to be born with a smaller head and often smaller brains that may not have developed properly.

2 Men Confirmed With West Nile Virus In Stanislaus County

From CBS Sacramento
June 22, 2020

STANISLAUS COUNTY (CBS13) — Two human cases of West Nile Virus have been confirmed in Stanislaus County, officials said on Monday.

According to a release from the Stanislaus County Health Services Agency, two men were recently tested and confirmed to have the virus. Both of the men were not showing any symptoms of the potentially deadly disease.

The two cases are the first two confirmed West Nile Virus cases confirmed in Stanislaus County this season.

West Nile Virus often spreads to people and animals through mosquito bites. It’s a disease that sees an increase in cases come the summer months.

While most people will only develop symptoms like headache, fever and fatigue, less than 1 percent of cases could develop into more serious complications.

This season, health officials say at least 10 California counts have been confirmed with West Nile virus through testing of dead birds and mosquito samples.

Mosquito Population Four Times Higher Than Normal in the San Gabriel Valley

From Pasadena Now
June 22, 2020

Mosquitoes were four times higher in numbers last week in San Gabriel Valley than they were in 2018 and 2019, data from the San Gabriel Valley Mosquito and Vector Control District (SGVMVCD) showed.

The data was reported out Sunday, as Pasadena begins to observe National Mosquito Control Awareness Week, June 21-28. The SGVMVCD obtained from mosquito surveillance traps examined between June 8 and 12 at various sites within the Valley, including Pasadena.

The SGVMVCD said they have tested mosquitoes collected in Hacienda Heights, the second largest census designated place in Los Angeles County, positive for carrying West Nile virus.

In Orange County, mosquito control officials confirmed they are detecting five times the average mosquitoes in their surveillance traps compared to 2019.

To prevent the spread of mosquitoes and mosquito-borne diseases, the SGVMVCD advocates for three simple steps that residents should practice: Tip, Toss and Protect – Tip out stagnant water, Toss unused containers that can collect stagnant water, and Protect yourself from mosquito bites by using repellent.

West Nile still biggest risk, but mosquito season may bring other threats

From the Daily Republic
June 19, 2020

FAIRFIELD — West Nile is not the only concern as mosquito season starts to take hold.

Chikungunya, dengue fever, yellow fever and Zika, all of which are costly to treat and can have long-term health and financial consequences, can be transmitted by infected mosquitos, which are known to be in California and are expanding their range.

Richard Snyder, manager of the Solano County Mosquito Abatement District, said the invasive Aedes mosquitoes have been found in neighboring counties, but not in Solano.

“They are in Sacramento County right now, and San Joaquin County,” Snyder said. “We have been actively surveilling for them with trapping methods, and hoping we don’t find any.”

Generally speaking, Snyder said, the mosquitoes are brought into a county by humans.

Double trouble: South Asia braces for dengue outbreak amid coronavirus pandemic

From CGTN
June 19, 2020

As the coronavirus continues leaving a trail of devastation behind globally, another deadly virus is rearing its ugly head in South Asia – dengue fever. 

The monsoon months in the region, between late May and September, bring much needed rain but also mosquito-borne diseases. And this includes dengue fever, an illness caused by an infection with a virus transmitted by the Aedes mosquito, which currently has no cure. 

Even without the backdrop of a global pandemic, dengue cases have seen a dramatic spike in the past decade due to erratic storms, rising global temperatures, and unplanned rapid urbanization. Last month alone, India and Bangladesh were hit by the biggest storm in 20 years, forcing five million to evacuate. 

An estimated 400 million dengue infections happen around the world each year, killing some 25,000 people annually. According to the World Health Organization, 2019 saw the most number of cases reported, with Asian countries bearing approximately 70 percent of the disease burden.

A perfect storm of events, including the COVID-19 pandemic, have boosted the mosquito population in Orange County, vector control officials said Wednesday.

Light misty rains in May, higher than usual spring temperatures, reductions in staffing due to the coronavirus pandemic, and the economic downturn discouraging residents from more regular cleaning of their pools are among the reasons for the higher mosquito counts, said Heather Hyland, a spokeswoman for the Orange County Mosquito and Vector Control District.

For the past six weeks, the OCMVCD has been averaging higher mosquito counts compared with the same period last year. The district’s traps are averaging 110 mosquitoes per trap, compared to 24 per trap last year at this time.

Press Release: Residents Need to Protect Themselves from Mosquitoes as They Head Outside Amidst Relaxing of Stay-at-Home Orders

National Mosquito Awareness Week educates residents about the importance of eliminating mosquitoes and preventing the spread of mosquito-borne diseases

SACRAMENTO, June 17, 2020 – As the weather heats up and residents head outside, mosquito experts encourage community members to protect themselves from mosquitoes and the diseases they can spread when they bite. West Nile virus is the most prevalent mosquito-borne disease in the U.S. according to the Centers for Disease Control and Prevention (CDC), California had the highest number of West Nile virus disease cases in the nation in 2019, with 225 cases reported. Comparatively, Texas had 32 cases and Florida had two cases in 2019. There is no human vaccine for West Nile virus, a disease that can cause debilitating cases of meningitis, encephalitis, and even death.

However, West Nile virus isn’t the only mosquito-borne threat in California. Newly established invasive Aedes mosquitoes can transmit viruses such as chikungunya, dengue, and Zika, all of which are costly to treat and can have long-term health and financial consequences. These mosquitoes are established in many areas of California and are steadily expanding their range.

Mistaken identity? Some Texans think mostly-harmless cicada killer wasps are Asian giant hornets

From KXAN
June 17, 2020

AUSTIN (KXAN) — Mostly-harmless Cicada killer wasps that emerge in Texas every summer are being confused for so-called Asian “murder hornets” that have caused panic in the United States, an entomologist has said.

She said there’s no need to worry here in Texas because the giant hornets, which can reach up to two inches in length, have not been found in the U.S. outside of Washington state.

Despite their name, cicada killer wasps are mostly harmless to humans – their name comes from their hunting of cicadas.

Entomologist Wizzie Brown said people have been emailing her with concerns about the cicada killers, which are being mistaken for the Asian giant hornets due to their large size and distinctive coloring.

The U.S. has 3,141 counties, but just one, Whatcom County in northern Washington state, has documented sightings of the Asian giant hornet, dubbed “murder hornet.” Even there, only three specimens have been confirmed.

But news reports about the hornets that went viral early May have sparked nationwide panic. For over a month, entomologists coast to coast have been swamped with questions and false sightings, and they say the frenzy has prompted a backlash: people are indiscriminately killing beneficial bumble bees, wasps, hornets and native species.

Volcanic Glass Could Potentially Control Mosquito Population

From Nature World News
June 10, 2020

The findings of a new study show that a residual spray that contains a combination of perlite, a type of volcanic glass, and water is effective against malaria-carrying mosquitoes. The study results can help reduce the populations of these mosquitoes in Africa and thereby reduce the risk of malaria.

According to the study, malaria is a fatal mosquito-borne disease and a primary cause of death of sub-Saharan Africans. This disease is also competing against TB and AIDS as the world’s deadliest infectious disease.

Malaria deaths in Africa have significantly gone down from an annual rate of 1.8 million deaths to an estimated of only half a million in 2020 through a combination of bed nets and indoor spraying. However, malaria-carrying mosquitoes are showing widespread resistance to pyrethroids and increasing resistance to recommended insecticides by the World Health Organization.

New antivirals for influenza and Zika

From EurekAlert!
June 9, 2020

Leuven researchers have deployed synthetic amyloids to trigger protein misfolding as a strategy to combat the influenza A and Zika virus.

Amyloids are particular protein assemblies with properties similar to silk, that serve numerous functions. They also form upon protein misfolding resulting in protein inactivation.

Frederic Rousseau and Joost Schymkowitz (VIB-KU Leuven) used these properties to invent synthetic amyloid peptides that can be tailored to switch-off the function of desired target proteins. These peptides, termed Pept-ins, already proved to be a valuable approach to tackle bacterial pathogens or slow down tumor growth. Now, Schymkowitz and Rousseau’s team wanted to explore whether pept-ins could also be used to inactivate viral proteins and thereby interfere with viral replication.

First Mosquito With West Nile Virus Found In San Diego County

From KPBS
June 5, 2020

A mosquito caught in routine trapping in the Black Mountain Ranch area has tested positive for West Nile virus, the first appearance of the virus in San Diego County in 2020.

County environmental health officials remind people to protect themselves from mosquitoes, which can potentially transmit the disease, by following the county’s “Prevent, Protect, Report” guidelines — including finding and dumping out standing water in yards and around homes to keep mosquitoes from breeding.

Incidences of West Nile virus were mild in San Diego County in 2019. Three people tested positive, but there were no fatalities and all three people were suspected of having contracted the virus while outside the county.

However, West Nile virus remains a potentially deadly threat in San Diego County and the state, officials said. In 2015, 44 San Diego County residents tested positive for West Nile virus and six died. In 2019, 225 California residents became sick from West Nile virus and six died, according to the California Department of Public Health.

A new threat to bees

From the Harvard Gazette
June 4, 2020

They’re here. Native to East Asia, the so-called murder hornets were spotted in North America for the first time late last year and just again in May. The presence of the predators, which can grow as much as 2 inches in length, drew media attention because their frightening prowess at killing honeybees means they could adversely affect the supply of foods we consume that require pollination. Known officially as the Asian giant hornet, the species is capable of wiping out an entire hive in a matter of hours, decapitating bees with powerful mandibles and hauling away the thoraxes to feed their young. The hornets are less of a direct threat to humans, although they do kill about 50 people a year in Japan, where they are most prevalent.

Brazil’s Zika Epidemic Worsens

From Zika News

As the COVID-19 disease pandemic dominates the world media headlines, the Zika virus has steadily put women and children at grave risk in the Federative Republic of Brazil.

Recently, Brazil’s Ministry of Health identified 579 new suspected cases of Zika between December 2019 and February 2020.

This is concerning news since a ‘Zika virus infection during pregnancy can cause congenital conditions in infants,’ said Human Rights (HRW), on May 28, 2020.

Due to the Zika virus, more than 1,600 babies were born in Brazil with microcephaly, or abnormally small heads, from September 2015 through April 2016.

Brazil’s Zika epidemic took health professionals by surprise because the virus had been known since 1947 and was not linked to birth defects.
