This year could bring record numbers of West Nile cases

04/10/2015 05:42 PM04/10/2015 05:53 PM

The potentially deadly West Nile virus is threatening to reach record highs in California this year and experts say the drought is to blame.

There were 801 cases of West Nile last year, the highest amount California has ever seen. This year, state health officials say it could be even worse. Health experts say one reason the numbers were so high last year is because it was a record hot year. Mosquitos, which carry the virus, are more abundant and active in hot temperatures.

California drought linked to West Nile virus outbreak

California saw a record number of deaths from the West Nile virus last year, and the state's drought may have contributed to the spike in infections, according to health officials.

Thirty-one infected people died in 2014, the most since California began recording West Nile cases in 2003, the state Department of Public Health said Wednesday.

There were 801 Californians who tested positive for the virus -- coming close to the record of 880 cases a decade ago.

West Nile in Texas ? May 21, 2015

DSHS has reported the state?s first case of West Nile illness this year, a case of West Nile neuroinvasive disease in a person from Harris County.
People should reduce their risk of exposure to the mosquito-borne virus that causes it by eliminating standing water and other mosquito breeding areas; making sure door, porch and window screens are in good condition; wearing long sleeves and long pants outdoors when possible and using an insect repellent that contains DEET, picaridin, IR3535, or oil of lemon eucalyptus/para-menthane-diol.
As many as 80 percent of people who contract the virus will have no symptoms at all. Almost all others will have West Nile fever with symptoms like headache, fever, muscle and joint aches, nausea and fatigue. A very small minority will develop West Nile neuroinvasive disease, a life threatening illness that can cause neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness and paralysis.
In 2014, there were 379 human cases of West Nile illness in Texas, including six deaths.

West Nile Virus


CDD - MosquitoWest Nile virus (WNV) is a reportable disease in Oklahoma. The first cases for 2015 have been confirmed in Okfuskee and McIntosh county residents. There have been no deaths. Persons are at greatest risk of exposure to infected mosquitoes from July through October in our state. Persons of any age can become ill after being bitten by an infected mosquito, but those over the age of 50 are at greater risk of developing serious illness involving the nervous system. Over 80% of people infected with the virus never become ill. If people do become ill, most cases are mild with symptoms such as a fever, headache, tiredness and body aches that go away on their own. Some people may develop a rash on the trunk of the body. In more severe cases, persons can develop meningitis or other neurologic disease.

FOR IMMEDIATE RELEASE June 10, 2015	KDHE Office of Communications communications@kdheks.gov, 785-296-0461

First Human West Nile Virus Positive Case Reported in Kansas for 2015

TOPEKA, Kan. -- The Kansas Department of Health and Environment (KDHE) is reporting the first reported case of West Nile virus for 2015. The individual that tested positive is an adult from Lincoln County.
West Nile virus can be spread to people through bites from infected mosquitoes, but it is not contagious from person to person. Symptoms range from a slight headache and low-grade fever to swelling of the brain or brain tissue and in rare cases, death. People who have had West Nile virus before are considered immune.
KDHE recommends the following precautions to protect against West Nile virus:

• When you are outdoors, use insect repellent containing an EPA-registered active ingredient on skin and clothing, including DEET, picaridin, oil of lemon eucalyptus, para-menthane-diol or IR3535. Follow the directions on the package.
• Many mosquitoes are most active at dusk and dawn. Be sure to use insect repellent and wear long sleeves and pants at these times or consider staying indoors during these hours.
• Make sure you have good screens on your windows and doors to keep mosquitoes out.
• Get rid of mosquito breeding sites by emptying standing water from flower pots, buckets and barrels. Change the water in pet dishes and replace the water in bird baths weekly. Drill holes in tire swings so water drains out. Keep children's wading pools empty and on their sides when they aren't being used.

West Nile virus cases are most common in the late summer and early fall months. Through mosquito surveillance conducted in Sedgwick County, we have seen an increase in mosquitoes that can spread West Nile Virus and therefore it is not surprising to see a case this early in the summer. In 2014, there were 54 cases of West Nile virus in Kansas. In addition to tracking cases of human illnesses caused by West Nile virus, KDHE assesses the potential for West Nile virus by conducting limited mosquito surveillance, including laboratory testing. At this time, there has not been a positive mosquito sample in Kansas.
Birds are not tested for West Nile virus in Kansas and KDHE will not be collecting information about dead birds. If you find a dead bird, KDHE recommends that you wear gloves, place the bird in a plastic bag, and dispose of it in the garbage.
The Centers for Disease Control and Prevention provides this web page with additional information about West Nile virus and preventing mosquito bites:http://www.cdc.gov/features/StopMosquitoes/ or visit the KDHE website: www.kdheks.gov/westnilevirus
West Nile virus case counts are updated each Tuesday on our website here: http://www.kdheks.gov/epi/case_reports_by_county.htm

First Reported Delaware Human West Nile Virus Case in Two Years

Date Posted: Thursday, June 25th, 2015
Categories: Delaware Health and Social Services Public Health

FIRST REPORTED DELAWARE HUMAN WEST NILE VIRUS CASE IN TWO YEARS

DOVER ?A 6-year-old Sussex County girl was briefly hospitalized with West Nile Virus (WNV) and is now recovering at home. The case is the first human WNV case reported since 2013. The mosquito-borne illness can become serious and the Division of Public Health reminds people to take precautions to avoid mosquito bites.
WNV is transmitted by mosquitoes, generally from spring to fall. Although nearly 80 percent of people infected with WNV will not become ill and only a little less than 20 percent of those infected will develop West Nile fever, with mild symptoms (fever, headache, body aches, a skin rash on the chest or back and swollen lymph glands), one in 150 people infected develop severe infection (West Nile encephalitis or meningitis).
Symptoms of severe WNV infection include headache, high fever, stiff neck, and/or tremors and muscle weakness. The elderly and those with weakened immune systems are most at risk. Anyone who experiences any of these severe symptoms should seek medical help immediately. Symptoms may progress to stupor, disorientation, coma, convulsions, paralysis, and possibly death.
?This new human case is a reminder that West Nile virus is still active in Delaware,? said Dr. Karyl Rattay, Division of Public Health Director. ?It?s tempting with the distractions of summer fun to forget to protect you and your loved ones from insect bites. These bites can cause much more serious health problems than just itching and discomfort.?
Mosquitoes can also carry Eastern equine encephalitis (EEE), and several other diseases that cause brain inflammation (encephalitis) and can be fatal to humans and animals. To avoid mosquito bites and reduce the risk of infection, individuals should:
? When outside, wear shoes, long-sleeved shirts, and pants. Mosquito netting can protect one?s face and neck, and infants in carriages, strollers, and playpens. Mosquitoes are most active at dusk and during the early-morning hours.
? Mosquito repellents containing DEET can be applied to the skin, but will last only a few hours before reapplication is necessary. Use insect repellent containing less than 50 percent DEET for adults. The current American Academy of Pediatrics and Centers for Disease Control and Prevention recommend using 10 to 30 percent DEET for children above 2 months old. The higher the strength, the longer the DEET provides protection which varies between two to five hours.
? Read labels carefully and always follow the instructions. DEET should not be used on children younger than 2 months.
? Prevent mosquitoes from entering the house by using screens and keeping windows and doorways tightly sealed. Mosquitoes prefer shallow water and tall vegetation. Eliminate standing water in your yard by changing birdbath water weekly, regularly draining pet dishes and plant pot saucers, and checking gutters, pool covers, and tarps for standing water. Store buckets, wheelbarrows, and wading pools upside down. Keep grass mowed.
In Delaware, there were no reported human WNV cases in 2014, three cases in 2013, and nine cases in 2012 with one fatality. To report suspected cases of human WNV, call the DPH Office of Infectious Disease Epidemiology at 888-295-5156.
To report high numbers of biting mosquitoes or other concerns, contact the Department of Natural Resources and Environmental Control (DNREC) Mosquito Control Section field offices:
? Glasgow Office (upstate) ? 302-836-2555, for all of New Castle County and the northern half of Kent County, including Dover.
? Milford Office (downstate) ? 302-422-1512, for the southern half of Kent County south of Dover, and for all of Sussex County.
Calls will be answered by staff from Monday through Friday between 8:00 a.m. and 4:00 p.m. Callers after business hours or during weekends or holidays should leave a message giving their name, phone number, address and a brief description of their need or problem.
For more information on DNREC Mosquito Control, call 302-739-9917 or visitwww.dnrec.delaware.gov/fw/Services/Pages/MosquitoSection.aspx.
For more information about WNV in horses, contact the Delaware Department of Agriculture at 302-698-4500 or 800-282-8685 (Delaware only).

First Human Case of West Nile Virus Reported to DHHS


Note: Sound bites on this topic will be available shortly at: www.dhhs.ne.gov/audio

Lincoln ? A person in the Central District Health Department area (Hall, Hamilton, and Merrick Counties) tested positive for West Nile virus according to the Nebraska Department of Health and Human Services. The person was not hospitalized.
?This is the first human case so far this season and we expect to see more,? said Dr. Tom Safranek, State Epidemiologist for DHHS. ?West Nile virus can be a mild illness for some and serious for others. If you haven?t been taking steps to protect yourself, it?s important to start now.?

Preventive tips:
Make sure your mosquito repellent contains DEET, picaridin, lemon eucalyptus oil or IR3535.
Dress in long-sleeved shirts, pants and socks when you?re outside.
Dusk and dawn are times when mosquitoes are most active. Limit outdoor activities.
Drain standing water around your home. Standing water and warmth breed mosquitoes.
West Nile virus is transmitted to people through the bite of a mosquito that picked up the virus by feeding on an infected bird. Most people who are infected will have no symptoms or only mild flu-like symptoms. Some people will develop a fever with other symptoms like headache, body aches, vomiting, fatigue and weakness. Less than one percent of people will develop a serious illness like encephalitis or meningitis (inflammation of the brain and surrounding tissues). People over 50 and those with weakened immune systems are especially vulnerable to the disease and are more likely to experience serious consequences.

DHHS started its West Nile virus surveillance at the beginning of June. One mosquito pool tested positive in Webster County. No birds have tested positive for the virus.

Health officials advise caution as monsoon rains increase mosquito activity

PHOENIX -- As the state enters monsoon season, the Arizona Department of Health Services is reminding residents to protect themselves and their homes against mosquitoes because of the risk of diseases such as West Nile virus, St. Louis encephalitis virus, and Western equine encephalitis. Maricopa County Department of Public Health (MCDPH) has confirmed the first human case of West Nile Virus in Arizona this season.
The infected individual is a male resident of Maricopa County in his late 50?s with no travel history. He experienced flu-like symptoms, but was not hospitalized and has since recovered.
?This is the time of year when we see an increase in mosquito-borne diseases that can cause serious illness, and in some cases can be deadly,? said Dr. Rebecca Sunenshine, medical director for the Disease Control Division at MCDPH. ?While this is our first confirmed case, there are likely many more out there and we expect our numbers to rise as the monsoon season continues.?
West Nile virus can cause severe illness in people and horses, although only about 20% of those infected will develop any symptoms at all, usually flu-like: fever, headache, body aches, and muscle weakness. Some people, especially the elderly, may experience severe disease including high fever, headache, neck stiffness, and/or encephalitis or inflammation of the brain, which can lead to paralysis or death. There were 108 human cases of West Nile virus reported statewide in 2014, 93 of which were in Maricopa County.
Mosquito populations increase dramatically during periods of high rainfall, and can spread serious diseases to people.
?By following a few simple guidelines you can reduce the risk of these diseases for yourself and your family,? said Dr. Cara Christ, director of the Arizona Department of Health Services.
To prevent the spread mosquito-borne diseases, please follow the prevention guidelines:

• Wear mosquito repellant or long sleeved shirts and pants when outside.
• Check your home for any containers that could hold water after rains or irrigation, including old tires, bottles, drums, and buckets.
• Ensure water-holding containers are covered or turned over to protect them from mosquito eggs.
• Make sure doors and windows have tightly fitted screens. Repair or replace screens with tears or holes in them.
• Clean and change the water in flower vases, birdbaths, planters and animal watering pans at least once a week.
• Repair leaky pipes and outside faucets.

Dr. Christ said people could also be infected with diseases from mosquitoes while traveling outside of Arizona. Some of the more common mosquito-borne diseases associated with travel include dengue, chikungunya, yellow fever, and malaria.
?It?s possible for someone to visit an area where there are mosquitos that carry a disease, such as dengue, and bring the disease back to Arizona,? Dr. Christ said. ?Taking a few extra precautions will not only help you protect your own health, but also the health of our entire state.?
In 2014, 108 cases of West Nile virus and one case of St. Louis encephalitis were reported among Arizona residents. In addition, 91 cases of dengue and 16 cases of chikungunya were reported among persons who had traveled outside of Arizona in 2014. Dengue and chikungunya have currently not been found in Arizona mosquitoes. For more information on mosquito-borne illness prevention, please contact the Arizona Department of Health Services at 602.364.4562 or visit us online at www.azdhs.gov.

Wyoming Reports First West Nile Virus Case of Season

7/10/2015

West Nile virus has returned to Wyoming with the season?s first case, involving a Sheridan County resident, being reported to the Wyoming Department of Health (WDH).

?We want to remind residents to take steps to protect themselves and their families from mosquito bites,? said Katie Bryan, epidemiologist with WDH. Mosquitos spread West Nile virus (WNV) when they feed on infected birds and then bite people, animals and other birds.

The ?5 D?s? of West Nile virus prevention include:

1) DAWN and 2) DUSK - Mosquitos prefer to feed at dawn or dusk, so avoid spending time outside during these times.
3) DRESS - Wear shoes, socks, long pants and a long-sleeved shirt outdoors. Clothing should be light-colored and made of tightly woven materials.
4) DRAIN - Mosquitos breed in shallow, stagnant water. Reduce the amount of standing water by draining and/or removing.
5) DEET - Use an insect repellent containing DEET (N, N-diethyl-m-toluamide). When using DEET, be sure to read and follow label instructions. Other insect repellents such as Picaridin (KBR 3023) or oil of lemon eucalyptus can also be effective.

Bryan said at least two states surrounding Wyoming have also had confirmed West Nile virus cases so far this season.

In Wyoming last year, five human WNV cases were reported. Since WNV first appeared in Wyoming in 2002, reported human cases within a year have ranged from two with no deaths to 393 and nine deaths.

Most people infected with WNV don?t have symptoms. Among those who become ill, symptoms include fever, headache, body aches, skin rash and swollen lymph nodes. A very small number develop West Nile neuroinvasive disease with symptoms such as severe headache, fever, neck stiffness, stupor, disorientation, coma, tremors, convulsions and paralysis.
