A southeast Fort Collins resident contracted West Nile Virus this week, the first confirmed case in Fort Collins and the second in Larimer County this season.

The Fort Collins case was mild and the resident displayed symptoms similar to the flu or a cold, Larimer County Health Department spokeswoman Katie O'Donnell said. It's not clear where the person contracted the virus, but it's likely they were bitten in the southeast Fort Collins area, O'Donnell said.

The other Larimer County case was in Loveland last month.

First Human Case of West Nile Virus Reported in LA County
All residents should take precautions against mosquitoes

LOS ANGELES ? The Los Angeles County Department of Public Health (Public Health) confirms the first human case of West Nile Virus (WNV) infection for the 2016 season in LA County (excluding Long Beach and Pasadena as cases identified in those cities are reported by their local health departments). Illness occurred in an elderly male from the Echo Park area with no prior medical history who was hospitalized for WNV disease in late June and is recovering at home. This case has been confirmed by the California Department of Public Health.
"This serves as a warning to residents that West Nile Virus is a serious disease that may require hospitalization and can even result in death for some individuals,? said Jeffrey Gunzenhauser, MD, MPH, Interim Health Officer for Los Angeles County. ?Elderly persons and other people with weak immune systems are at highest risk of developing severe illness. Protect yourself from mosquitoes by using insect repellent containing an effective ingredient such as DEET, and eliminating any stagnant water around your home where mosquitoes can breed. Do it for your kids, do it for your grandkids, do it for yourself.?

In 2015 in LA County, 300 human infections and 24 fatalities due to WNV were reported. Most patients were older adults who experienced serious illnesses, such as meningitis and encephalitis. For many, recovery from their illness can take a year or more with ongoing physical and mental impairment. There is no specific treatment for this disease. In most years, the first case of WNV occurs at this time of the year, and cases continue through October or early-November.

Public Health performs surveillance to identify people with WNV, and collaborates with local vector control agencies to target areas for mosquito control activities and health education. WNV-infected mosquitoes have been identified in several areas across LA County and all county residents are encouraged to take protective action to prevent mosquito bites. Because of the recent human case, Public Health asks residents of Echo Park to be particularly diligent in using personal protection and reducing mosquito breeding sites.

"Vector control agencies in LA County cannot do it alone,? said Truc Dever, General Manager for the Greater Los Angeles County Vector Control District. ?It is imperative that the public help minimize the risk of being bitten by removing sources of water on their property that can breed mosquitoes. This is not a virus to take lightly. Additionally, residents should report dead birds, and also report sources of standing water to their local vector control agencies."

About West Nile Virus:

WNV is primarily spread to humans through the bite of an infected mosquito; mosquitoes can become infected by biting a bird that carries the virus. Most mosquitoes do not carry the virus and most people bitten by a mosquito are not exposed to the virus. The virus is not spread through person-to-person contact or directly from birds to humans.

WNV illness can be very severe, causing meningitis, encephalitis, paralysis, and death. Serious disease usually occurs in older adults and those with underlying medical conditions that reduce their immunity. These severe illnesses represent ?the tip of the iceberg? with most infections resulting in no illness or mild symptoms that include fever, headache, nausea, body aches, and skin rash. Symptoms of WNV could appear within three to 12 days after infection.

Decrease risk of infection:

Avoid mosquito-infested areas at dawn and dusk.
Regularly use mosquito repellents containing EPA- registered ingredients such as DEET, picaridin, or oil of eucalyptus.
Wear long-sleeved shirts and long pants whenever you are outdoors.
Repellents containing DEET, picaridin, or oil of eucalyptus, when used as labeled, are effective defenses against mosquitoes.
Check your window screens for holes.
Do not allow water to collect and stagnate in old tires, flowerpots, swimming pools, birdbaths, pet bowls, or other containers. These are prime breeding grounds for mosquitoes.
Clean and chlorinate swimming pools; drain water from pool covers.
Stock garden ponds with goldfish or other mosquito- eating fish. These eat mosquito eggs and larvae.
Empty and wash birdbaths and wading pools weekly.

West Nile in Texas – July 20, 2016 (Ro's note: Dallas county has now announced 6 confirmed cases)

DSHS has confirmed seven cases of West Nile illness among Texas residents this year. People should reduce their risk of exposure to the mosquito-borne virus that causes it by eliminating standing water and other mosquito breeding areas and avoiding mosquito bites.
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 2015, there were 275 human cases of West Nile illness in Texas, including 16 deaths.

Confirmed Human Infections of West Nile Virus in Yolo County
Post Date:07/25/2016 9:12 AM
Press Release

(Woodland, CA) ? Yolo County confirmed today that two residents have tested positive for West Nile virus. While both residents are symptom-free, West Nile virus can pose a serious health risk.

West Nile virus is most commonly spread to humans through the bite of a mosquito. Mosquitoes become infected when they feed on infected birds. Infected mosquitoes can then spread the virus to humans and other animals. West Nile virus can cause fever, encephalitis (inflammation of the brain) or meningitis (inflammation of the lining of the brain and spinal cord). Most people (70-80%) who become infected with West Nile virus do not develop any symptoms. About 1 in 5 people who are infected will develop a fever with other symptoms such as headache, body aches, joint pains, vomiting, diarrhea, or rash. Less than 1% of people who are infected will develop a serious illness.

According to Sacramento-Yolo Mosquito & Vector Control District Manager Gary Goodman, there is high West Nile virus activity in Yolo County right now, which can be viewed on the district?s website at: www.fightthebite.net/west-nile-virus-activity-map. The most effective way to avoid West Nile virus disease is to prevent mosquito bites. Yolo County Health & Human Services and the Sacramento-Yolo Mosquito & Vector Control District encourage everyone to practice the "Three Ds:"

1. DEET ? Apply insect repellent containing DEET, picaradin, oil of lemon eucalyptus or IR3535 according to label instructions. DEET can be used safely on infants and children two months of age and older.

2. DAWN AND DUSK - Mosquitoes bite in the early morning and evening so it is important to wear proper clothing and repellent if outside during these times. Make sure doors and windows have tight-fitting screens, free of tears or holes, to keep out mosquitoes.

3. DRAIN - Mosquitoes lay their eggs on standing water. Eliminate or drain sources of standing water such as flower pots, old car tires, bird baths, pet bowls and buckets. Residents are encouraged to notify the Sacramento-Yolo Mosquito & Vector Control District (toll-free 1-800-429-1022) of swimming pools not being properly maintained.

California's West Nile virus website (www.westnile.ca.gov) includes the latest information on West Nile virus activity in the state. Californians are encouraged to report dead birds on the website or by calling toll-free 1-877-WNV-BIRD (968-2473)

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

First Human West Nile Virus Positive Case Reported in Kansas for 2016

TOPEKA, Kan. -- The Kansas Department of Health and Environment (KDHE) is reporting the first reported case of West Nile virus for 2016. The individual that tested positive is an adult from Thomas County.

West Nile virus is be spread to people primarily through bites from infected Culex species mosquitoes, although the virus has been detected in more than 60 different mosquito species in the U.S. West Nile virus is not contagious from person to person. The Culex species are known to transmit West Nile virus; they are not known to transmit Zika virus.

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 and other mosquito-borne diseases:

When you are outdoors, use insect repellent containing an EPA-registered active ingredient, including DEET, picaridin, oil of lemon eucalyptus, or IR3535. Follow the directions on the package.
Many mosquitoes are most active at dusk and dawn, but can bite at any hour. Be sure to use insect repellent and wear long sleeves and pants at peak 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. In 2015, there were 34 cases of West Nile virus in Kansas, and more than half of these cases were hospitalized.

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/

KDHE conducts mosquito surveillance primarily in Sedgwick County. For more information, visit: http://www.kdheks.gov/epi/arboviral_disease.htm

West Nile virus case counts are updated each Tuesday on our website here: http://www.kdheks.gov/epi/case_reports_by_county.htm

First Positive Human Case of West Nile Virus

The location of the confirmed case was in the 6400 block of MacIntosh Dr, 75023. The address is approximately one block southwest of the City?s previous south spray boundary of Seabrook. This follows yesterday?s two confirmed locations of mosquitoes that tested positive. The City intends to expand the southern boundary for targeted spraying tonight to include Blue Ridge (West), Burlington Drive (North), Alma Drive (East) and Bluebonnet Trail (South).

The City?s Environmental Health Department urges citizens to stay inside during the spraying, along with any pets or animals. They?re also urging the common prevention practice of the 4 D?s:

Drain standing water in and around your home and neighborhood.

Dusk, daylight and dawn are ideal times that mosquitoes are most active. Limit outdoor activity during these times.
Dress appropriately before going outdoors.

Deet (N, N-diethyl-m-toluamide) is an ingredient to look for when purchasing insect repellent. The use of bug spray is recommended at all times, especially during the day.

Citizens with concerns or questions can call the City of Plano Environmental Health Department at 972.941.7143.

POSTED:AUG 04 2016 06:11PM CDT
UPDATED:AUG 04 2016 06:12PM CDT
ST. PAUL, Minn. (KMSP) - The Minnesota Department of Health confirms two people have contracted West Nile Virus making for the first cases of the 2016 season.

Department of Health spokesman Doug Schultz says the first confirmed case was a woman in her 50?s from Clay County who contracted a mild fever from the virus. The second victim is a man from Kandiyohi County who came down with more severe symptoms. Schultz says the cases are right on target for a typical West Nile season.


First cases of West Nile virus confirmed in Minnesota
?When you start getting into August, some of the mosquitos that spread that disease are doing really well,? said Mike McLean of the Minnesota Mosquito Control District. ?They?re starting bite people, so this time of the year is the time when West Nile is becoming more active.?

West Nile Virus was first confirmed in Minnesota in 2002. Since that time the number of cases each year have varied from a high of 148 in 2003 to a low of just two in 2012. During the past 14 years at least 18 people have died from the virus.

CDPH Confirms First Human West Nile Virus Death of 2016
Aug 5, 2016
SACRAMENTO - California Department of Public Health (CDPH) Director and State Health Officer Dr. Karen Smith today announced the first confirmed death in California due to West Nile virus (WNV). The deceased person was a senior citizen in Sacramento County.

"West Nile virus can cause a deadly infection in humans, and the elderly are particularly susceptible, as this unfortunate fatality illustrates," said Dr. Smith. "West Nile virus activity in the state is increasing, so I urge Californians to take every possible precaution to protect themselves against mosquito bites."

CDPH has reported ten human cases of WNV from eight California counties this year. In addition, 764 dead birds from 26 counties have tested positive for WNV in 2016 and 1,487 mosquito samples from 30 counties have also tested positive for WNV this year.

The number of WNV positive dead birds and mosquito samples exceeds the numbers at this same time last year and are above the state's most recent five-year average.

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. West Nile is transmitted to humans and animals by the bite of an infected mosquito. The risk of serious illness to most people is low. However, some individuals - less than 1 percent - can develop serious neurologic illnesses such as encephalitis or meningitis.

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.

CDPH recommends that individuals protect against mosquito bites and WNV by practicing the "Three Ds":


DEET - Apply insect repellent containing DEET, picaradin, oil of lemon eucalyptus or IR3535 according to label instructions. Repellents keep the mosquitoes from biting you. Insect repellents should not be used on children under two months of age.

DAWN AND DUSK - Mosquitoes usually bite in the early morning and evening so it is important to wear proper clothing and repellent if outside during these times. Make sure that your doors and windows have tight-fitting screens to keep out mosquitoes. Repair or replace screens that have tears or holes.

DRAIN - Mosquitoes lay their eggs on standing water. Eliminate all sources of standing water on your property, by emptying flower pots, old car tires, buckets, and other containers. If you know of a swimming pool that is not being properly maintained, please contact your local mosquito and vector control agency.

California's West Nile virus website includes the latest information on WNV activity in the state. Californians are encouraged to report dead birds on the website or by calling toll-free 1-877-WNV-BIRD (968-2473).
