BAKERSFIELD, Calif. – Mosquito season is in full swing. Experts at Mosquito and Vector Control say they’re trapping more mosquitoes this year compared to last.

“Swimming pools have turned into the biggest source and problem we have in urban areas,” said Gene Abbott, the district manager at Kern Mosquito and Vector Control.

Vector Control monitors and eradicates mosquito breeding from bodies of water around the county–for free. They say mosquitos only need one teaspoon of water to breed.

“It’ll breed in anything from a saucer of water to an open septic tank. they’re really not picky about the quality of water,” Abbott said.

More importantly than the itch mosquitoes cause, Kern Public Health says the Culex mosquito, which carries the West Nile Virus, is quite common locally.

According to Public Health, Kern County had 30 cases of West Nile Virus in 2017, with one death. They say there have been two cases so far in 2018.

Zika doesn’t dominate headlines the way it did when it suddenly became widespread in the Americas in 2016.

But the virus is still a serious problem. If a pregnant woman is infected, Zika virus can cause babies to be born with neurological damage and microcephaly (a particularly small head and underdeveloped brain).

The CDC still says that pregnant women, their partners, and people considering pregnancy should postpone travel to large parts of the Caribbean and Latin America.

Researchers are desperately searching for a way to fight the virus. That effort requires a better understanding of the structure of Zika, which would makes it easier to design vaccines or anti-viral drugs.

It’s ‘National Mosquito Awareness Week’ and after mosquitos tested positive for West Nile Virus in parts of the valley this month, Coachella Valley Vector Control is expanding its outreach hoping to raise awareness to people and visitors in the affected areas.

Vector control’s public information officer Jill Oviatt is going to hotels and Homeowner Associations in Palm Desert and Indian Wells dropping off several items including mosquitos swatters, repellents, and wipes. Oviatt is also reminding those people to protect themselves from mosquitos.

It’s a message vector control spreads year round, but the organization is being even more proactive about it after several mosquitos tested positive for WNV.

“Suddenly we saw it in Indian Wells and Palm Desert which is very rare. But after doing our truck mounted operations, we’re seeing a drop in the mosquito population and no more virus activity at this time, but it could pop up here or somewhere else in the valley,” Oviatt said.

PALM DESERT, Calif. – Local residents in Palm Desert are guarding themselves against some pesky mosquitoes. It comes after West Nile was detected in mosquitoes trapped in one neighborhood last week.

“I don’t them. I don’t like them at all,” Jeffrey McCartney said.

That’s how he feels about seeing these pesky mosquitoes. McCartney’s taking even more precautions than usual after some mosquitoes carrying West Nile was detected in his neighborhood.

“Them being right on this street is very concerning,” he said.

The Coachella Valley Mosquito and Vector Control District (CVMVCD) says it’s the second city to have West Nile detected this month. Indian Wells was the first. McCartney has already taken steps eliminating standing water where mosquitoes breed.

“Our watering is a drip system so it doesn’t leave any big puddles and as you can see in the front of the yard, is a desert plan,” he said.

The CVMVCD plans to spray the area for mosquitoes as shown in this sign posted on Portola avenue.

As residents of California’s Coachella Valley escape the blazing heat this summer in air-conditioned living rooms, movie theaters and cars, many will hear this upbeat but cheesy refrain:

“Dump it! Drain it! Scrub it clean! Your weekly mosquito prevention routine.”

These commercials feature local mosquito-control officials grinning goofily at the camera while they follow the jingle’s instructions to eliminate pools of water that harbor insects they are branding as “bloodthirsty killers.”

Nationwide, diseases spread by ticks, fleas and mosquitoes have tripled since 2004. In California, last summer brought the deadliest West Nile virus season in 15 years.

Authorities in the Coachella Valley and other regions of the state are trying to drive home the message that mosquitoes are a serious and growing threat to residents’ health. Using jingles, disaster drills and even drones, they are spreading the word and preparing for outbreaks.

Jill Oviatt, a spokeswoman for the Coachella Valley Mosquito and Vector Control District, calls the ad campaign an attempt to “brainwash” residents and force them to rethink mosquitoes as more than buzzing, irritating, itch-making pests. With climate change and the spread of diseases across international boundaries, they pose a lethal threat.

It’s true. Mosquitoes like some people more than others.

The annoying insect also loves to breed in California. The state is home to the most mosquito-transmitted diseases in the country, according to the Centers for Disease Control.

Around 50 mosquito species are attracted to the state’s hot summers and mild winters, as well as agricultural areas like rice fields and stagnant pools in urban areas. Not to mention California is the most populated state in the nation.

During peak summer temperatures, mosquitoes can grow from an egg into an adult in less than a week.

Over the last five years, Zika virus has emerged as a significant global human health threat following outbreaks in South and Central America. Now, researchers reporting in PLOS Neglected Tropical Diseaseshave shown that invasive mosquitoes in California — where cases of Zika in travelers have been a regular occurrence in recent years — are capable of transmitting Zika.

Zika virus (ZIKV) is a mosquito-transmitted flavivirus that has been known for more than a half century, but recently gained attention after it began spreading through South America and was confirmed as a cause of Guillain-Barre syndrome and congenital Zika syndrome in infants. Several species of Aedes mosquitoes have been confirmed as vectors of ZIKV in the lab. But studies have also suggested that mosquitoes of the same species from different regions may have different competencies as vectors.

DEAR JOAN: Every year around this time, a herd of suicidal beetles appears in our basement, which is built into a hill. There is sandy ground in some areas, and one wall faces the outside. The beetles appear out of nowhere and I cannot find any opening to the outside they could have used to enter the basement.

Most of them are dead when I find them, but sometimes they are still alive. When I capture them to bring them outside, they make a deep humming sound. They are about 1 to 1½ inches long. I find them until about August or September, then they are gone again.

How can I prevent these beautiful beetles from continuing to commit suicide, and what are they?  Help please.

Sacramento, June 20, 2018 – California leads the nation in mosquito-borne disease cases over the last decade, according to new data from the U.S. Centers for Disease Control and Prevention. The State reported 9,254 cases of mosquito-transmitted diseases between 2004 and 2016, followed by New York with 7,167 and Texas with 6,648. California had 100 times more mosquito-transmitted disease cases than Alaska (87), which reported the lowest number of cases in the country during the same period.

The time is here and so are the mosquitoes. And with mosquitoes comes mosquito-borne viruses such as the Zika virus. It is crucial to take preventative measures when spending time outdoors to protect yourself from the dangers of Zika and other mosquito-borne diseases.

We’ve all been victim of mosquitoes and the red, itchy bumps they leave behind. Unfortunately, mosquito bites can also become dangerous as the Zika virus has made its way into the United States.

The Zika virus is primarily spread through the bite of an Aedes mosquito. The mosquitoes become infected after biting a human who has the virus, which then allows the virus to be spread to other humans with each bite that the mosquito makes. According to the Center for Disease Control, 662 Zika virus cases were reported in 2017, with Texas being one of the hardest hit states.

Two mosquitoes found in Stockton’s 95219 ZIP code area tested positive for West Nile virus in testing done by the San Joaquin County Mosquito and Vector Control District.

“This is the first find of WNV in San Joaquin County for 2018,” said Aaron Devencenzi, public information officer of the district. “With warm weather, mosquito populations will continue to increase, leading to an elevated risk of WNV in humans.”

In addition to work by the mosquito and vector control district, reduction of West Nile virus and other mosquito-transmitted diseases is dependent on all residents. The district recommends:

• Eliminate all sources of standing water on your property that can support mosquito breeding.

• Apply insect repellent containing the active ingredient DEET or Picaridin when outdoors, according to label instructions.

• Avoid spending time outside when mosquitoes are most active, at dawn and dusk, and especially for the first two hours after sunset.

• When outdoors, wear long pants, long-sleeved shirts and other protective clothing.

• Exclude mosquitoes from your home with tight fitting screens on doors and windows.

• Contact your veterinarian for information on vaccinating equine against WNV.

SACRAMENTO – The California Department of Public Health (CDPH) announced today the first confirmed illnesses in California due to West Nile virus (WNV). The four illnesses occurred in Los Angeles, Kern and Riverside Counties. “West Nile virus activity in the state is increasing, so I urge Californians to take every possible precaution to protect against mosquito bites,” said CDPH Director and State Public Health Officer Dr. Karen Smith. 

West Nile virus is transmitted to humans and animals by the bite of an infected mosquito. As of June 8, 2018, WNV has been detected in 14 dead birds from seven counties and four mosquito samples from three counties. Hot temperatures this month are contributing to increasing numbers of mosquitoes and the increased risk of virus transmission to humans. So far this season, activity is within expected levels. The risk of disease due to WNV usually increases at this time of year and is highest throughout the summer and early fall. West Nile virus is influenced by many factors, including climate, the number and types of birds and mosquitoes in an area, and the level of WNV immunity in birds. The risk of serious illness to most people is low. However, some individuals – less than one percent – can develop serious neurologic illnesses such as encephalitis or meningitis. In 2017, there were 553 reported WNV cases in California, including 44 deaths. People 50 years of age and older, and individuals with diabetes or hypertension, have a higher chance of getting sick and are more likely to develop complications from WNV infection.

Three years ago, the Zika virus was making nearly daily headlines — its devastating effects on babies born to mothers who were infected by the virus triggered global public emergencies and thousands of canceled trips to Latin America and the Caribbean. Even some Olympians decided against participating in the 2016 Games because of the risk of getting bitten by a mosquito and becoming infected by Zika in Rio de Janeiro.

Now the infection has all but disappeared from the media landscape and conversation.

The Zika virus was first reported in the Western Hemisphere in 2015, just as the West African Ebola virus epidemic was declining. Though it was initially believed to be the result of a well-known related pathogen, the dengue virus, or possible exposure to a toxic insecticide, it soon became clear to clinicians and researchers that it was in fact a newly emergent virus.

Zika spread rapidly from northeastern Brazil to other South American countries, through Central America and up to the Caribbean, leaving a large number of people infected. The symptoms typically were mild and nonspecific — rash, fever and joint pain. Many of those infected had no symptoms at all.

A platform that can diagnose several diseases with a high degree of precision using metabolic markers found in patients’ blood has been developed by scientists at the University of Campinas (UNICAMP) in Brazil.

The method combines mass spectrometry, which can identify tens of thousands of molecules present in blood serum, with an artificial intelligence algorithm capable of finding patterns associated with diseases of viral, bacterial, fungal and even genetic origin.

The research was supported by the São Paulo Research Foundation – FAPESP and conducted as part of Carlos Fernando Odir Rodrigues Melo’s PhD. The results have been published in Frontiers in Bioengineering and Biotechnology.

“We used infection by Zika virus as a model to develop the platform and showed that in this case, diagnostic accuracy exceeded 95%. One of the main advantages is that the method doesn’t lose sensitivity even if the virus mutates,” said Melo’s supervisor Rodrigo Ramos Catharino, principal investigator for the project. Catharino is a professor at UNICAMP’s School of Pharmaceutical Sciences (FCF) and head of its Innovare Biomarker Laboratory.

The reason there is no universal flu vaccine is because the influenza virus constantly changes. That’s why we get jabbed with a new vaccine every season; the vaccine from the previous year is unlikely to work against the strains of flu circulating this year.

The hunt for a universal influenza vaccine is based on targeting parts of the virus that don’t change. In theory, antibodies generated against these portions of the virus should confer protection against all influenza viruses. Whoever develops and successfully demonstrates such a vaccine should win a Nobel Prize.

But this may not be the only strategy for the creation of universal vaccines. Indeed, a team of researchers who are concerned by mosquito-borne illnesses has described a very clever idea for the development of universal vaccines in the Journal of Infectious Diseases.

They are an unfortunate part of summer – crawling, biting, flying, irritating hordes – and because of weather patterns, we may be seeing more of them.

“Winter kind of lasted until the middle of April for much of Wisconsin,” Gundersen Infection Preventionist Megan Meller said. “That’s a perfect condition for some of these insects like ticks and mosquitoes.”

The CDC says illnesses from ticks, mosquitoes and fleas have tripled since 2004, with tick-borne illnesses accounting for 60 percent of all those cases. Wisconsin and Minnesota are in the top 20 percent of reported cases.

“There’s other types of Lyme disease that are out there,” Meller said. “So it’s really best that we just be prepared for that.”

It takes more than 24 hours for a tick to transmit disease. Thorough body checks after a day in the woods or tall grass is key to prevention.

Recent temperature fluctuations notwithstanding, warm weather has returned to the Bay Area, and with it comes the annual onslaught of disease carriers like mosquitoes and ticks, county officials warned last week.

Locally, May and June are considered the start of the active West Nile virus season, and Lyme disease peaks in ticks in July, according to Russell Parman, Santa Clara County Vector Control District assistant manager.

“As things heat up, most of the processes that go on inside the bug also run faster,” Parman said.

FLYING FOES

Culex tarsalis (Western encephalitis mosquito) and Culex pipiens (Northern house mosquito) are the two local mosquito species that transmit West Nile, a viral infection that can lead to flu-like symptoms and even death.

Vector Control has yet to trap any mosquitoes infected with the virus so far this season. Last year’s season marked the first time the agency did not detect West Nile-positive mosquitoes since 2004, when the virus appeared in Santa Clara County.

“We’re hoping for the same this year, but it’s not likely,” Parman said.

Officials also hope to keep Zika, the birth-defect-causing virus, at bay. Aedes aegypti (yellow fever mosquito) and Aedes albopictus (Asian tiger mosquito), the species capable of transmitting Zika, are not native to California and are not currently active in the Bay Area, but they have been in the past. Aedes aegypti was discovered in Menlo Park in 2013 and Aedes albopictus made an appearance in Mountain View in 2003, according to Vector Control.

Butte County Public Health is urging all horse owners to get their trusty steeds vaccinated for West Nile virus, the mosquito-borne illness transmitted to animals and people through the bite of an infected mosquito.

Horses are at high risk for the virus because they spend most of their time outdoors, including dusk and dawn, when mosquitoes capable of transmitting the disease are most active. West Nile virus-carrying mosquitoes breed in standing water, including ponds, water troughs and irrigation run-off, increasing the risk for horses.

While the last reported West Nile virus horse death in Butte County occurred in 2012, 21 horses statewide including some in Sacramento, Tehama and Glenn counties were confirmed positive for WNV in 2017.“We issue this reminder to get horses vaccinated every year in May or early June before the active WNV season really begins,” said Lisa Almaguer, Health Department communications manager. “It’s a precautionary measure because one-third of the horses affected with WNV die or have to be euthanized.”

County officials said they believe the mosquito is more nuisance than human health risk. However, it is aggressive and prefers to live and breed near people; in yards and even inside homes.

“One of the best things you can do to protect yourself from mosquitoes is to get rid of all standing water so they can’t lay eggs and breed near you,” said Chris Conlan, a supervising vector ecologist with the County’s Vector Control Program. “That means dumping water out of the saucers under flowerpots and toys laying in the yard. These mosquitoes are called the ‘backyard mosquito’ for a reason.”

County Vector Control found three adult female Australian backyard mosquitoes last week in a trap they placed in La Mesa in response to a complaint about mosquito bites. The mosquito had previously been found in Los Angeles about three years ago.

This year there have already been more than 40 travel related Zika cases in Florida – 15 of those were found in Southwest Florida.

On top of that, local researchers say conditions are right for another outbreak.

“You don’t have to wait many years in between these outbreaks,” said biology professor, Scott Michael. “Sometimes they [the outbreaks] catch us by surprise.”

Michael teaches at Florida Gulf Coast University (FGCU) and is also one of the leading researchers in the fight against Zika.

“Studying viruses is my way of helping,” Michael said. “These things are global as well as local.”

The work being done in his lab will go beyond Florida – it is going to reach parts of the world that need it.

Michael said the Zika virus is still a big issue for people in the Caribbean.

He said it not only takes an economic toll but also an enormous amount of human suffering, especially with children.

SAN JOSE (KRON) – Like the proverbial canary in the coal mine, a pair of dead birds has tested positive for West Nile Virus on the Peninsula–and that means mosquito season is here and vector control is taking action. 

Dead crows found in Mountain View and Palo Alto have tested positive for West Nile Virus.

It means that mosquito season has arrived and with it the potential for the spread of the virus to humans.

“Once the mosquitoes are flying, and we know a certain proportion of them have the virus in them, they’re like little hypodermic needles and anyone who gets bitten by one of those mosquitoes is going to acquire an infection,” Santa Clara County Vector Control Assistant Manager Russ Parman said.

That’s why vector control is hunting for mosquitoes breeding. Trapping and testing are underway.

So far, no human cases of West Nile have been reported, but the virus is out there and the threat is real.

SPRINGFIELD, Ill. (KWQC) — The Illinois Department of Public Health has identified that mosquitoes from Glenview and Morton Grove, Illinois have tested positive for West Nile virus.

North Shore Mosquito Abatement District staff collected the positive mosquitoes on May 25, 2018. No human cases of West Nile virus have been reported so far this year.

Monitoring for West Nile virus in Illinois includes laboratory tests for mosquito batches, dead perching birds, as well as testing sick horses and humans with West Nile virus-like symptoms.

Zika, bird flu, West Nile virus, Nipah: The world is constantly being warned of a new disease that threatens to wipe out humanity, and then it doesn’t. Why?

RACHEL MARTIN, HOST:

The World Health Organization is in the midst of an experimental campaign to vaccinate tens of thousands of people in Congo against Ebola. The country is battling a new outbreak of the disease there. Also in the news – an outbreak of a deadly disease called Nipah in India. These are just some of the latest viruses to raise alarms around the world. Two years ago, it was Zika – before that, bird flu. Health officials say all these viruses have the potential to kill millions, and yet they haven’t. NPR’s Michaeleen Doucleff is here to explain why.

Hi, Michaeleen.

MICHAELEEN DOUCLEFF, BYLINE: Hi, Rachel.

MARTIN: So what’s going on? Why are there so many false alarms, if we can call them that?

DOUCLEFF: Yeah, so first off, I don’t want to minimize the power of these diseases. These are incredibly destructive outbreaks, even when they’re small or just restricted to a small area. For instance, the Ebola outbreak in West Africa killed more than 11,000 people. But for viruses to turn into pandemics that wipe out millions of people, they need two things – a high mortality rate, and they need to spread very easily. And it turns out, for viruses, this is really hard. For instance, Ebola – it’s very deadly but doesn’t actually spread very quickly or well. Same goes for Nipah, the virus that just cropped up in southern India. It kills up to 70 percent of people infected, but it also doesn’t spread very well.

The hot weather likely drew a few pesky and uninvited guests to holiday picnics this past weekend.

Mosquito season has returned and so has the annual reminder for folks to do their part in helping keep the mosquito population at bay.

Kane County Health Department spokesman Tom Schlueter said what most people are experiencing is a nuisance mosquito, which is not known for carrying disease.

The real threat, he said, comes from the Culex mosquito because it carries the dangerous West Nile virus. Last year 90 people tested positive for West Nile in Illinois, and eight people in the state died from the disease, according to Illinois Department of Public Health figures.

Because this mosquito species prefers hot, dry weather and its females lay their eggs in stagnant, still water, Schlueter said it’s critical to drain any liquid that’s accumulated in containers, flower pots, old tires and gutters and to change the water in bird baths weekly.

So far this year, no mosquitoes trapped in Kane or DuPage counties have tested positive for West Nile.

(CNN) – An increase in birth defects associated with a 2015-2016 epidemic of Zika virus in Brazil caused widespread concern, fear and in some cases hysteria throughout the Americas. Now, research suggests that broadcasts of the epidemic coupled with dire health warnings inspired a very real response from the population.

About 120,000 fewer babies than expected were born from late 2015 through 2016, after the Zika outbreak began in Brazil, according to a study published this week in the scientific journal PNAS. The findings suggest that, due to fears of potential effects of a Zika virus infection during pregnancy, Brazilians postponed pregnancy or possibly had an increased number of abortions, the authors say.
