The 'raiders' have landed

Joe and Patty Harmon set up a mosquito net in their backyard to prevent the annoying creatures from interfering with daily outdoor activities. The Harmons love the outdoors too much to give it up, so now they are prepared.
 
“This time we are determined to have it – to be a mosquito refuge,” Patty Harmon said. With mosquitoes coming out more often than not, Kansans should be prepared for the worst, as there are now two mosquito-borne diseases to look out for – West Nile virus and chikungunya.
“It’s hard to tell if we have more (mosquitoes) than we ever had,” said Julia Hulsey, director of the Reno County Health Department.

Chikungunya is a new mosquito-borne virus that has spread quickly in the Caribbean since December. Chikungunya symptoms include fever, muscle and joint pain, rash and headaches, which appear within a few days to a week after a person is bitten and can last for about a week.
There have been no confirmed cases in Kansas, and all reported cases in the United States have been from travelers visiting or returning to the U.S. from affected areas, according to Aimee Rosenow, a spokeswoman for the Kansas Department of Health and Environment.

Advance Pest Control in Hutchinson said the phone calls are just coming in for mosquitoes, and they anticipate more calls this year than last, based on the rate of calls in the past week. They have a lot of repeat customers year-to-year, said Jeff Wells, mosquito technician.

Patty Harmon said she always wears bug spray. As Harmon’s grandson, Trent Biehler, who was just visiting from Olathe, emptied rainwater that was collecting from the top of the tent, Harmon said the original use for the canopy was for shade, but its newfound use would be for mosquitoes.
“I just started noticing them,” Harmon said. “We’ve set (the canopy) up so we can enjoy – have dinner, a glass of wine and good conversation.”

While visiting his grandparents, Biehler plays basketball with some neighborhood teens around 8:30 p.m., “which probably isn’t the best idea,” he said. He explained they usually run out of bug spray by the end of the night.

“Mosquitoes aren’t really a big deal for me,” Biehler said. “We just keep moving.”
There are no reported cases of West Nile virus in Kansas yet, according to Rosenow. Last year, according to the Centers for Disease Control and Prevention, 91 cases of West Nile virus were reported in Kansas, resulting in seven deaths.

Patty Harmon has to contend with mosquitoes to get her gardening work done, so she empties standing water and puts on bug spray when she is outside, but she doesn’t seem to mind the simple prevention techniques.

“We have to protect ourselves,” she said. “And I enjoy the gardening so much that it’s worth it.”
The city of Hutchinson will not be spraying, or fogging, this year. The city stopped spraying in 2009 after it was determined to be ineffective because the chemical spray had to come into immediate contact with the mosquito larvae, The News reported last year.

Surrounding areas, including Buhler, Haven and Sterling, will be spraying.
“Be aware. That’s our biggest role right now,” said Nick Baldetti, assistant director of the Reno County Health Department.

Scripps Florida scientist awarded $2.3 million to study dengue fever and related viruses

March 27, 2014 – The outbreak of dengue fever that infected some 20 people in Florida's Martin County late last year unnerved many who feared the tropical disease had once again established a foothold in Florida. The last outbreaks occurred in 2009 and 2010 in Key West—before that, the disease hadn't struck Florida in more than 70 years.

Now, scientists from the Florida campus of The Scripps Research Institute (TSRI) have been awarded $2.3 million to study a category of viruses that cause dengue fever, West Nile, yellow fever and other diseases spread by mosquitoes and ticks. These diseases can result in flulike symptoms, extreme pain (dengue has been called "bone-break fever") and, in some cases, encephalitis.

This family of viruses, called "flavivirus," affect some 2.5 billion people worldwide and cause hundreds of thousands of deaths each year. There are no antiviral treatments and a just handful of vaccines that provide protection against only a few of these diseases.

The principal investigator for the new five-year study is TSRI Associate Professor Hyeryun Choe, who will lead the effort to understand the virus's mode of infection and how new therapies might interrupt it.

"Flavivirus uses a very clever method of infection," Choe said. "It's like using a side door to enter a house when the front door is locked."

The viruses take advantage of the process that normally occurs during programmed cell death. During programmed cell death ("apoptosis"), a lipid usually found on the inner side of the cell membranes, specifically phosphatidylserine (PS), shifts to the surface, making itself readily available to any passing cellular stranger. This is where the trouble begins.

When cells are dying from a flavivirus infection, their freshly exposed PS is grabbed by the exiting virus, and phagocytes—cells that devour invading pathogens and dead and dying cells—engulf the virus as if it were a dying cell. Once engulfed by the phagocyte, the virus quickly turns the cell's own biology on its head, forcing it to produce copies of the virus.

While some viruses (influenza A for example) do not use PS in their life cycle, the flavivirus exploits this opportunity to the hilt. Infection of cells by dengue or West Nile viruses is markedly enhanced when phagocytes express receptors that recognize and bind PS.

It appears, however, that flaviviruses use only a subset of these receptors. The high selectivity, and the potency with which some of these receptors promote flavivirus infection, suggest only a small number of receptors might be effectively targeted to treat these diseases.

"We want to understand which PS receptors contribute the most to flavivirus infections and how we might block them," Choe said. "Our studies are designed to offer insights useful in the development of new therapies."

Eagle Scout candidate organizes bat condos


SAN ANTONIO - 
                
Condo living isn't just for people anymore.

More than a thousand free-tail bats are getting ready to move into their new home thanks to a local Eagle Scout candidate.

Will Judson of Boy Scout Troop 809 said he wanted to do something a little different to benefit the community.

The bat condos, donated by the San Antonio Parks Department, will house up to 1,600 bats that will feed on nearly 7 million mosquitoes every night.

"Mosquitos are a nuisance to people daily, so I figured why not do a favor to the community and limit some of the mosquito problems here,"said Judson.

The condos stand about 16 feet tall and will house the bats that will consume about 3.5 tons of mosquitos annually.

It’s not the hordes of mosquitoes biting you in the spring that you have to worry about. It’s that old, scraggly mosquito that’s still around in August

 
This summer’s multiple heavy rains have contributed to the number of mosquitoes, but only marginally, McLean said. Each storm typically results in another brood of bugs showing up within a week or two. But, so far at least, we’re within the normal range for hatches.
 
“In a typical summer, we’ll have six to eight broods,” he said. “This year, we’re on our sixth brood. Last year, the rain stopped in late July and everything dried out in August. We don’t know what’s going to happen next.”
 
Because the backlog of hatches has caught up, the worst of the bug baby boom is likely behind us. But those bugs aren’t going away. We’ll merely return to the normal levels.
 
And, as we head into August, we’re in the prime season for the spread of the West Nile virus. “We’re not out of the woods yet,” McLean warned.
 
Mosquitoes that have spent the first part of the summer biting birds — where West Nile originates — spend the last half of the summer biting humans, which is how the disease is passed on.
 
“The typical thinking is that the more bugs that are biting you, the higher your chances are of getting a disease, but that’s not true,” McLean said. “It’s not the hordes of mosquitoes biting you in the spring that you have to worry about. It’s that old, scraggly mosquito that’s still around in August.”
 
That’s why McLean urges people to stay diligent about repelling mosquitoes.
 
“People tend to put on lots of repellent early in the year when the bugs are heavy but then cut back in August,” he said. “Don’t do that.”
 
Last year saw a startling surge in the West Nile virus, with 70 confirmed cases in the state, compared with only two in 2011.
 
With so many variables, experts aren’t predicting how bad the disease might be this year, but they’re thinking that one reason for last year’s surge was the ultra-early spring that resulted in a much longer-than-normal bug season.
 
If that’s the case, there actually might be a silver lining to our long wait for summer this year.
 
 

West Nile Virus Threat Looms in Cook County

Officials at the Cook County Department of Public Health say weather over the last week has provided an ideal breeding ground for West Niles Virus-carrying mosquitos, and residents need to take precautions right now.

Cook County Department of Public Health (CCDPH) officials say now is the time to take simple, but effective precautions to help protect you and your family against contracting West Nile Virus from the Culex mosquito, which carries the disease.
After recent heavy rains, Amy Poore, director of public relations for the Cook County Department of Public Health, says residents should empty any items in and around their homes that have collected water, such as old tires, bird baths, baby pools, buckets and other objects.

Poore said these areas provide the most ideal breeding ground for Culex mosquito.
“This is really the time to pay attention, you can reduce your risk by making sure there are no tears in your screens at home, wear repellant with DEET, oil of lemon Eucalyptus or Picaridin between dusk and dawn and keep your gutters clean,” Poore said.

Residents also are advised to keep yard grass cut short, because tall grass also is an ideal area where the Culex mosquito can breed.

Poore said surveillance to identify Culex mosquitos already has been conducted by the CCDPH, in addition to Mosquito Abatement districts in Cook County. Mosquito traps are set in suburban Cook County communities to determine if the insects are carrying West Nile Virus.
Though there are no reported human cases yet in Cook County, Poore said more than 2,000 mosquito pools already have tested positive in Wheeling, Evanston, Skokie, Alsip, Evergreen Park, Forest Park, Hillside, Hodgkins and Oak Park.

Because of the lapse time between trapping the mosquitos and determining if they are indeed carrying West Nile, Poore said it is possible that mosquitos carrying the virus are spreading to neighboring communities - so taking precautions now is even more important.

Cook County residents can also help to curb the spread of the Culex mosquito by reporting any dead birds they observe. Poore said many times, mosquitos feed on dead birds that are carrying West Nile.
If you observe a dead bird near you, you are urged to report it to the CCDPH online or call 708-633-8025 immediately.

For more information on West Nile Virus and how to protect you and your family, visit the Cook County Department of Public Health website.
