Mosquitoes With West Nile Virus Found In Milpitas

From KPIX
June 9, 2020

MILPITAS (CBS SF) – Crews with Santa Clara County Vector Control plan to spray mosquito control treatments in parts of Milpitas later this week, after insects that have the West Nile Virus were found.

Mosquitoes collected in the 95035 zip code tested positive for the virus, officials said in a statement Monday.

In response, spraying will take place late Thursday night in an area bordered by Dixon Landing Road to the north, North Milpitas Boulevard and North Abel Street to the east, Highway 237 and Bellew Drive to the west and North McCarthy Boulevard to the West.

People living in the area do not need to relocate, but are urged to stay inside their homes to minimize exposure, Vector Control said. The chemicals, which are widely used by other Vector Control agencies, have been approved by state and federal regulators.

“I get mosquito bites all the time for the last two weeks actually,” said Efrain Garcia.

According the Coachella Valley Mosquito and Vector Control District, 15 mosquito traps valley wide have been tested positive for the West Nile virus including 38 infected mosquitos found in Cathedral City on Friday.

“As temperatures rise up so will the mosquito numbers and as birds migrate, which is mosquitos favorite food, they carry WNV and St. louis encephalitis virus (slev),” said Tammy Gordon.

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
June 4, 2020

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.

Can The ‘Murder Hornet’ Destroy Our Food And Honey Supply?

From Huffpost
May 29, 2020

As if we don’t have enough to worry about, now there’s a “murder hornet.” It’s the nickname for an Asian giant hornet, and according to breathless reporting about the insect, which was discovered in December in Blaine, Washington, it can wipe out entire honeybee hives in hours. And it doesn’t appear to be going away any time soon.

That’s concerning to anyone who cares about our food supply, as honeybees are responsible for pollinating a long list of foods many of us take for granted at the grocery store.

But how much of the hype around the “murder hornet” is just that? We spoke to three bee experts about whether the insidious insect could kill enough honeybees to damage our food supply.

Zika infection soon after birth leads to long-term brain and behavior problems

From Medical Xpress
May 26, 2020

Researchers from the Yerkes National Primate Research Center have shown Zika virus infection soon after birth leads to long-term brain and behavior problems, including persistent socioemotional, cognitive and motor deficits, as well as abnormalities in brain structure and function. This study is one of the first to shed light on potential long-term effects of Zika infection after birth.

“Researchers have shown the devastating damage Zika virus causes to a fetus, but we had questions about what happens to the developing brain of a young child who gets infected by Zika,” says lead researcher Ann Chahroudi, MD, Ph.D., an affiliate scientist in the Division of Microbiology and Immunology at Yerkes, director of the Center for Childhood Infections and Vaccines (CCIV), Children’s Healthcare of Atlanta (CHOA) and Emory University, and an associate professor of pediatrics in the Division of Pediatric Infectious Diseases at Emory University School of Medicine. “Our pilot study in nonhuman primates provides clues that Zika virus infection during the early postnatal period can have long-lasting impact on how the brain develops and works, and how this scenario has the potential to impact child behavior,” Chahroudi continues.

Asian giant hornets sighted in US for first time, UC Davis entomologists say media exaggerated severity of issue

From The Aggie
May 22, 2020

Despite sightings of giant hornet species, spread through North America highly unlikely, experts say

Giant, tiger-striped insects have been making quite the buzz lately. Vespa mandarinia, or the Asian giant hornet, typically lives in eastern and southeastern Asia, but two individuals of the species were sighted in the U.S. for the first time.

The Washington State Department of Agriculture (WSDA) verified two reports of the Asian giant hornets near Blaine, Washington in December of 2019. One report was of a dead hornet, while the other was of one spotted flying back into the forest. Additionally, a giant hornet nest was found and destroyed in a park south of Nanaimo, British Columbia, Canada.

In Washington, neither the second hornet nor its nest were found, but researchers are fairly confident their removal efforts were successful. In April, Blaine local authorities alerted residents to the possible threat and asked them to stay vigilant, according to the WSDA.

“They found a dead individual and were able to confirm that, yes, this is Vespa mandarinia,” said Eleanor Field, a doctoral candidate in entomology from Iowa State. “Then the same resident also said, ‘Hey, I saw another one and it went off into the woods.’ That means we have one confirmed dead individual and another presumed confirmed sighting.”

What’s ‘bugging’ your dog? Let’s take a look

From the Chico Enterprise-Record
May 14, 2020

You’ve just returned home from a springtime walk through the woods with your furry pal, and you see something on her fur that looks like a piece of dirt. But then you see it’s moving. It’s not dirt, it’s a disgusting TICK!

I have no idea why we’re not equally repulsed by the blood-sucking mosquito … yet both of these pests can be equally dangerous to our canine companions.

Ticks

The tick that carries the greatest danger to people and pups alike is the western black-legged tick or deer tick, the only one of California’s 48 tick species that transmits Lyme disease. Today, this tick can be found in 56 of California’s 58 counties.

While Lyme is far less serious in dogs than in humans, dogs with the disease can have a number of health issues, including lameness, swollen joints, fever, loss of appetite, swollen lymph glands, and in rare cases, chronic kidney disease.

BUTTE COUNTY MOSQUITO AND VECTOR CONTROL DISTRICT WILL FLY HIGH TO FIGHT ‘BACKYARD BREEDERS’

From Action News Now
May 14, 2020

BUTTE COUNTY, Calif. – The Butte County Mosquito and Vector Control District and the Butte County Sheriff’s Department are teaming up to conduct aerial surveillance of areas to locate and treat possible mosquito breeding sources.

Starting the week of May 18, the Butte County Mosquito and Vector Control District will conduct aerial surveillance of un-maintained swimming pools and other “backyard breeders,” such as, boats holding water, ponds without circulation, unused tires, un-maintained hot tubs, and other man-made objects holding water.

“It is crucial for the District to locate and treat these suspected mosquito-breeding sources early in the mosquito season to prevent larger populations from hatching off in the summer, when virus is most active” said Matt Ball, District Manager of Butte County Mosquito and Vector Control District.

Public health officials said they expect the mosquito-transmitted West Nile virus to be a serious public health concern in California this year.

In 2019, the West Nile virus was extremely active in Butte County, as well as the rest of the state, according to health officials.

Mosquitoes’ taste for human blood may grow as African cities expand

From Science Magazine
May 12, 2020

n most of the world, the Aedes aegypti mosquito is notorious for biting humans and spreading dengue, Zika, and other viruses. But in Africa, where the mosquito is native, most Aedes prefer to suck blood from other animals, such as monkeys and rodents. A new study suggests, though, that their taste for humans may rapidly expand—and with it their ability to spread disease.

By surveying the range of Aedes biting preferences across Africa, the study shows that dryness and dense populations favor strains that target people. Those conditions are likely to intensify in Africa with climate change and increasing urbanization, though not everywhere.

“The work is significant because the better we can understand where and why mosquitoes like humans, the better equipped we will be to predict and mitigate disease spread,” says Mara Lawniczak, an evolutionary geneticist at the Wellcome Sanger Institute, who was not involved in the study.

Why Wasps, Ticks, and Mosquitoes Are More Dangerous Than Murder Hornets in Summer 2020

From Medicine Net
May 12, 2020

Huge, invasive “murder hornets” may be scary, but so are the typical native species of hornets, bees, mosquitoes, and ticks that cause disease and death in the US every year.

A warm, wet winter means all those pest populations are spiking early this spring and will likely thrive through the summer.

The National Pest Management Association publishes a “Bug Barometer” report every year in its Pestworld trade journal to give members an idea of what to expect in the coming season.

“(Winter weather) conditions allowed vector pests such as ticks, responsible for the spread of Lyme disease, and mosquitoes, common vectors of West Nile virus, Zika virus and Eastern equine encephalitis to get a jumpstart on activity,” said Jim Fredericks, Ph.D., chief entomologist for the NPMA, in a release. “With more warm and wet weather predicted for summer across most of the US, we’ll likely see these populations, and others, rapidly expand.”

Zika Virus Tied to Profound Developmental Delays

From U.S. News
May 11, 2020

Toddlers with congenital Zika syndrome have severe developmental delays, researchers report.

In a study that covered a five-year period, researchers found that children in Brazil with congenital Zika syndrome who had microcephaly at birth suffered severe mental delays.

Microcephaly is a condition in which the head is smaller than normal. Its severity was the only significant factor linked to developmental delays, according to the study authors.

The study included more than 120 children. At age 2.5 years, nearly all of these children were functioning like 2-month to 4-month-old babies.

“The research findings reinforce public health concerns during the Zika outbreaks in 2015 and 2016 regarding the severity of disability that children with [congenital Zika syndrome] and their caregivers will be experiencing in the years to come,” said public health analyst Anne Wheeler of RTI International, a nonprofit research institute in Research Triangle Park, N.C.

Mosquitos Don’t Carry COVID-19, But They’re Still A Threat In California

It’s getting to be mosquito season in California, and public health officials say people need to be vigilant about avoiding bites.

Mosquitos don’t spread COVID-19, but they do carry West Nile Virus, which has sickened more than 6,000 Californians since 2003, according to state data. There’s no vaccine for it, and it can be fatal.

And this year some counties may not be taking their usual vector control measures. The National Association of County and City Health Officials says department budgets are strained due to coronavirus, and mosquito testing might go by the wayside.

Mosquitos Carrying Dengue, Zika, Yellow Fever Would Be More Prevalent by 2030, Study Warns

From The Science Times
May 9, 2020

A new study by the Imperial College London warns that mosquitos carrying diseases such as dengue, Zika, and yellow fever would likely colonize parts of southern Europe by 2030.

The changes in weather patterns and the rising temperatures will make many parts of the world viable homes for these insects. Scientifically known as Aedes aegypti, currently only thrives in the hottest regions of the world.

As global warming continues, the range of their habitat from Africa, the Amazon, and northern Australia could expand to other countries, including Spain, Portugal, Greece, and Turkey in the next ten years. More so, the invasion in China and southern continental America will also be accelerated by around four miles every year by 2050.

A Kenyan-British team of scientists has discovered a microbe to stop malaria transmission

From Quartz Africa
May 7, 2020

Scientists in Kenya have discovered a novel method with significant potential to completely stop mosquitos from transmitting the parasites which cause malaria in humans.

The team of scientists, mostly from Kenya and the UK, plus one from South Africa, have been studying mosquitoes on the shores of Lake Victoria in Kenya. They discovered that Microsporidia MB, a microorganism that lives in a mosquito’s gut and reproductive tract, completely protects the mosquito from being infected with plasmodium, the parasite that causes malaria.

Microsporidia are fungi, or at least closely related to them. Like plasmodium, which are protozoans, they are also known to live inside mosquitoes as parasites. Mosquitoes inject their saliva into the skin to facilitate blood-feeding. Their saliva sometimes contains plasmodium, which is usually injected together with their saliva resulting in malaria transmission. According to the study, the Microsporidia MB reduces the establishment of the Plasmodium falciparum parasite in the guts of the mosquitoes, and impairs the colonization of the salivary glands by the parasite.

Genetically Engineered Male Mosquitos to be Released in Florida and Other Parts of US to Curb Zika and Dengue Spread

From The Science Times
May 6, 2020

Mosquitos are best known as pests causing itch-inducing bites and spread harmful diseases such as dengue fever and Zika virus. But, they still are with purpose as many of them help pollinate plants and serve a vital role as a food source to fish, birds, and other animals in the food chain above them.

However, mosquitos, for the most part, are a huge problem for humans. So much that researches are conducted to ensure they can no longer harm any person. The Environmental Protection Agency has recently approved a new and controversial field test aimed at reducing their population.

The plan is to release genetically modified male mosquitos that over time will lead to lesser regular mosquitos in the population.

Brazilian Study Assesses Developmental Delays in Children with Congenital Zika Syndrome

From Contagion Live
May 5, 2020

As children born in 2015 and 2016 with congenital Zika syndrome age, investigators are gradually able to assess neurodevelopmental outcomes.

The team behind a recent study published in JAMA Network Open observed substantial developmental delays at ages 2-3 years across all areas evaluated. The investigators also found that severity of microcephaly at birth was significantly associated with the severity of these developmental delays.

The study was a case series of behavioral and medical needs of 121 young children with serologic confirmation of congenital Zika syndrome . Children were assessed at a rehabilitation center in the Brazilian city of Recife, starting in January of 2018 and intended to continue for a 5-year total longitudinal term.

The comprehensive assessment was based on the Brazilian edition of the Bayley Scales of Infant and Toddler Development, administered by trained specialists. Interviews with caregivers and reviews of medical records provided basic demographic information and comorbid medical conditions.

The median age of participants was 31.2 months. The gender distribution was 58 boys and 61 girls. Out of 121 children, 99 children had microcephaly at birth with 74 cases classified as severe. A majority of participants, between n106 to 118, scored at the floor of 1 or more scales. There was, however, variability on raw and age-equivalent scores. A standard score of 55 for the cognitive domain was assigned to children with raw scores between 1-42, for example.

Bethesda, MD – Zika virus is capable of replicating and spreading infectious particles within the outermost cells lining the vaginal tract, according to new research. The findings provide the first molecular-level insights into how the virus can move from person to person through sexual contact.

While Zika is primarily spread by mosquitoes, researchers have been aware of its potential for sexual transmission based on cases in which people became infected after having sex with a partner who had visited a Zika-affected area. Previous studies have also found Zika particles present in semen and vaginal fluid from infected individuals.

Purdue Professor: Extremely Unlikely Mosquitoes Can Transmit COVID-19

From Hoosier Ag Today
April 22, 2020

There is currently no evidence that COVID-19 can be transmitted by mosquitoes, a Purdue University professor says.

In the swells of information that have surrounded the COVID-19 pandemic, Catherine Hill, a professor of entomology and vector biology, said one question that keeps popping up is whether animals, including mosquitoes, can infect humans with the virus. Scientists around the world are currently assessing if mosquitoes pose a risk in terms of COVID-19 transmission but, so far, there is no evidence to support this idea and, for many reasons, it is extremely unlikely mosquitoes are able to transmit the virus.

“It is early days but we’re always looking at things from a risk management and assessment perspective and I think the risk is very low,” Hill added.

COVID-19 belongs to the coronavirus family and other viruses, including SARS (severe acute respiratory syndrome) and MERS (Middle East respiratory syndrome), in this family are not transmitted through mosquitoes.

To kick off California Mosquito Awareness Week and the mosquito season, GLACVCD will unveil its new mascot, Rita the Mosquita. Rita, a black and white striped Aedes mosquito, will make her debut on the District’s social media platforms on Monday, April 20th.

Visit the District’s social media pages daily on Facebook, Twitter, and Instagram during California Mosquito Awareness Week to answer mosquito-related questions. One participant will be randomly selected each day for the distinguished Citizen Excellence Award. To join in on the fun, participants must reside or work in the District’s service area and must follow or like the District’s social media pages.

Are Pregnant Women Aware of Zika Risks?

A new study highlights interactions between pregnant women and their healthcare providers were very positive.

This study was published in the Centers for Disease Control and Prevention (CDC) on April 16, 2020, and was conducted during the height of the 2016 Zika outbreak.

These researchers found there was a high awareness (91%) about the risk of Zika virus infection during pregnancy and about travel advisories to avoid visiting affected areas.

In the adjusted analysis, women younger than 24 years old were more likely not to have heard of Zika compared with women older than 35 years old.

And, Hispanic women were more likely to have heard of Zika.

Women with a high school education or less, women whose deliveries were paid for by Medicaid, and those who were uninsured at delivery were less likely to have heard of Zika, compared with their counterparts with more than a high school education and private health insurance.

Spring is in the air and so are mosquitoes. And with people socially distancing at their homes, they need to be careful if spending more time in the backyard.

The Sacramento-Yolo Mosquito and Vector Control District is now reporting that Mosquito and West Nile Virus Awareness Week, will be held starting today and continuing through next Saturday.

This week kicks off the District’s public information and education campaign to keep residents aware about the health risks associated with mosquitoes.

The current focus on the importance of public health with the COVID-19 pandemic also provides a great reminder that residents need to take all precautionary measures to protect themselves from mosquito-transmitted diseases.

During focus on COVID-19, prepare for mosquito season

Mosquito experts throughout the state say the increased attention on public health is an excellent reminder that there are many ways for residents to protect themselves from other viruses transmitted by infected mosquitoes.

While COVID-19 is not transmitted by mosquitoes, they can transmit several other diseases. West Nile virus is a mosquito-borne disease that has impacted the lives of California residents since 2003. There is no human vaccine for West Nile virus which can cause debilitating cases of meningitis, encephalitis, and even death.

“As we enter mosquito season, I urge all residents to take precautions to protect themselves from mosquito-transmitted diseases,” said Senator Henry Stern. “Having lost a dear friend to West Nile virus, I can tell you how real and devastating the risks are. By raising awareness and encouraging individual action, we can protect health and save lives.”

To raise awareness and educate Californians about the public health threat mosquitoes pose to our communities Mosquito and Vector Control Awareness Week is observed April 19-25, 2020.

Moderna Zika vaccine shows promising action in early-stage study

Ahead of its Vaccines Day event today, Moderna (NASDAQ:MRNA) reports positive results from a Phase 1 study of its Zika vaccine candidate mRNA-1893.

Preliminary results for the 10 µg and 30 µg dose levels showed seroconversion (antibodies develop and are detectable) rates of 94% and 100%, respectively, while being well-tolerated.

The NIH-led Phase 1 study of its COVID-19 vaccine candidate, mRNA-1273, remains on track with enrollment at the highest dose.

The company says its prophylactic vaccines have demonstrated immunogenicity against all eight viruses targeted thus far.

It has nine candidates in development for RSV (older adults and young children), human metapneumovirus and parainfluenza virus type 3, coronavirus, influenza H7N9, CMV, Zika and Epstein-Barr.

UC Davis Researchers Launch New COVID-19 Tracking Application

Researchers at the University of California, Davis, have developed a new web application that allows users to track COVID-19 cases and testing across the globe. The app offers a simple, intuitive way for users to track COVID-19 data at the country, state and county level.

“I found many of the best real-time visualizations of the COVID-19 data to be either complex dashboards or snapshots associated with media stories that made it difficult to get a simple, quick comparison of the latest COVID-19 trends,” said Christopher Barker, an associate professor of epidemiology with the UC Davis School of Veterinary Medicine who led the project.

Zika Carrying Mosquitoes ‘Wiped-Out’ In California

From Zika News
April 7, 2020

An experimental program to almost eliminate disease-causing mosquitoes succeeded in nearly eliminating them from test sites in California’s Central Valley.

The effort appears to be paying off, according to a paper published in the journal Nature Biotechnology.

According to news reports on April 6, 2020, stamping out illness caused by mosquitoes is one of Google/Alphabet unit Verily’s most ambitious public-health projects, the Debug Project.

The insects are bred in Verily labs to be infected with a common bacterium called Wolbachia.

When these male mosquitoes mate with females in the wild, the offspring never hatch.

Verily’s study revealed that throughout the peak of the 2018 mosquito season, from July to October, Wolbachia-infected males successfully suppressed more than 93 percent of the female mosquito population at field test sites.

Here’s something easy you can do to fight disease this spring. While the efforts to end COVID-19 have upended daily life, it may only take a few simple steps to stop the carriers of other dangerous diseases — mosquitoes.

As the weather starts to warm up in April and May, mosquito control districts across California are urging people to go through their yards and eliminate breeding places for mosquitoes that can transmit dengue fever, a painful and sometimes deadly disease that has exploded worldwide.

“Make sure you don’t have things that can hold water,” said Gary Goodman, manager of the Sacramento-Yolo Mosquito and Vector Control District. “Small children’s toys, small buckets.”

A Google-parent plan to wipe out mosquitoes appears to be working

From The Middletown Press
April 6, 2020

An experimental program led by Google parent Alphabet to wipe out disease-causing mosquitoes succeeded in nearly eliminating them from three test sites in California’s Central Valley.

Stamping out illness caused by mosquitoes is one of Alphabet unit Verily’s most ambitious public-health projects. The effort appears to be paying off, according to a paper published in the journal Nature Biotechnology on Monday.

Verily is also running coronavirus triage and testing in parts of California. Bradley White, the lead scientist on the Debug initiative, said mosquito-suppression is even more important during the pandemic because outbreaks of mosquito-borne diseases such as dengue fever can further overwhelm hospitals.
