West Nile Virus detected in 240 counties/34 states


East Valley woman dies from West Nile virus

PHOENIX -- Maricopa County Department of Public Health confirmed its first 2010 death from West Nile virus.

It was announced Wednesday that the victim, an elderly woman with pre-existing health conditions, was a resident living in the East Valley.

Ten people in Maricopa County have tested positive for West Nile virus so far this year. Most of the cases were in the East Valley.

"Unfortunately, most of these cases have the more severe form of West Nile virus, which is meningitis and/or encephalitis," said Craig Levy with the Arizona Department of Health Services.

"Because most people with milder symptoms of West Nile stay at home and don't seek medical care, we rarely hear of these cases," Levy continued. "That means there are a lot more people sick with West Nile than we know of."

West Nile virus is transmitted through the bite of an infected mosquito. So far this year, more than 100 mosquito samples have tested positive for West Nile virus all over the state, although many have been in the East Valley.

"Maricopa and Pinal counties have been finding a lot of positive mosquitoes in the East Valley, so it is not surprising the human cases are from that area," Levy said.

However, he warns that everyone in Arizona needs to be cautious.

"Just because the first mosquitoes and human cases were in that area, it is not limited," Levy said. People all over Arizona need to take this seriously."

West Nile virus can cause severe illness in people and horses, although only about 20 percent of those infected will develop flu-like symptoms, including fever, headache, body aches and muscle weakness.

Some people, especially the elderly, may experience more severe symptoms including high fever, severe headache, neck stiffness, and/or encephalitis or inflammation of the brain.

Health officials from Maricopa and Pinal counties, as well as ADHS, urge all people to "Fight the Bite" and follow simple precautions to avoid mosquitoes and the diseases they may carry:

• Avoid outside activity between dusk and dawn, when mosquitoes are most active.

• Wear lightweight clothing that covers your arms and legs and use an insect repellent if you must be outdoors when mosquitoes are active. Always follow the directions on the label.

• Make sure doors and windows have tight-fitting screens and remain closed.

• Eliminate mosquito-breeding sites around your home by removing standing water in potted plants, tires, bird baths and other containers where water may collect.

• Ensure that swimming pools and decorative water features are properly maintained.

• Change water in flowerpots, bird baths and pet bowls located outdoors at least twice per week.

Many local vector control programs around the state have been treating mosquito breeding habitats and some counties have been fogging to kill the specific mosquito that spreads West Nile virus. If you notice green pools in your neighborhood, talk to your neighbors or notify your county.

West Nile virus was first found in Arizona in 2003. Since then, more than 900 human cases have been reported. The worst year was 2004 with 391 human cases and 16 deaths. Last year, there were only 20 human cases of West Nile in Arizona and no deaths.

The first human case of the West Nile Virus has been confirmed in New York City.

The state health department says a 61-year-old Bronx man contracted the virus and has been hospitalized.

Another woman from Long Island was confirmed to have it earlier this month.

A report about cases of the virus in upstate New York has not been released, but Health Commissioner Dr. Richard Daines is encouraging people to be aware of their surroundings.

"Avoid mosquito bites in general is a very important preventative measure and then there will be local spraying where we've got a concentration of mosquitoes," says Dr. Daines.

Symptoms of the west nile virus include neck stiffness, disorientation, coma and paralysis.

MADISON, Wis. (AP) -- The first human case of West Nile Virus this year has been reported in Wisconsin.

The Department of Health Services reported Wednesday that a person in Washington County was diagnosed with the virus during routine screening of blood donations. All the blood donated by the infected person was destroyed to prevent it from entering the blood supply. The person later reported being ill with mild symptoms.

Most cases of the virus are mild, with symptoms including a fever, headache and rash that lasts a few days. Symptoms may begin between 3 to 15 days after being bitten by an infected mosquito.

Last year only one human case was reported.

The virus will be monitored until the end of mosquito season, typically in October.

West Nile Virus found in mosquito in Bell County
Posted: Oct 14, 2010 9:14 PM


BELL COUNTY - The West Nile Virus is in Central Texas.

The Bell County Public Health District says the virus has been documented in a recent mosquito sample in Bell County.

The virus is a potentially serious illness that is transmitted through mosquito bites, but the easiest and best way to avoid it is to prevent mosquito bites.

The Texas Department of State Health Services and Centers for Disease Control and Prevention released the following information regarding the virus.

Cases usually occur in the late summer or early fall, however, Texas has a variety of climates, and when temperatures are mild, West Nile Virus can be transmitted year round. It is best to protect yourself all year. The "Four D's" should be implemented to defend against West Nile Virus.

CDC says U.S. deaths from West Nile virus jump to 41

The number of West Nile virus cases in the U.S. jumped dramatically in one week, increasing to 1,118, with 41 deaths, the Centers for Disease Control and Prevention said today.

The report marks a substantial increase from last week's tally of 693 cases and 26 deaths.

Approximately 75% of the cases have been in five states: Texas, Mississippi, Louisiana, South Dakota and Oklahoma, the CDC says.

Texas has been hardest hit, accounting for almost half of all cases.

As of Tuesday there had been 21 deaths and and 586 cases there, says Christine Mann with the Texas Department of State Health Services.

"The number of West Nile cases in people has risen dramatically in the last few weeks and indicates that we are in one of the biggest West Nile virus outbreaks we have ever seen in this country," says Lyle Petersen, director of the CDC's Division of Vector-borne Infectious Diseases.

So far this year, 47 states have reported West Nile virus in humans, birds or mosquitoes, the CDC says. Thirty-eight states have reported cases of the human disease.

The 1,118 cases are the highest number of West Nile virus disease cases reported to CDC through the third week in August since the virus was first detected in the United States in 1999, the CDC says.

Up to 20% of people who contract West Nile virus develop symptoms that include fever, headache, body ache, swollen lymph glands and occasionally a rash on the trunk of the body. Symptoms appear within three to 12 days and then disappear within a few days.

About 80% of people infected with the West Nile virus have no symptoms.

Of those who develop a fever, fewer than 1% develop West Nile neuroinvasive disease which causes inflammation of the brain, spinal cord or the tissue surrounding the brain. About 10% of those will die, says Marc Fischer, medical epidemiologist with CDC's mosquito borne illness division in Ft. Collins, Colo.

People older than 50 and those with compromised immune systems are more likely to develop this form.

The West Nile virus first appeared in the United States in 1999, from Africa.
Texas West Nile outbreak now worst in history

The outbreak of West Nile disease in Texas this summer has become the most active and lethal in the state's history, the state health commissioner said Wednesday.

Dr. David Lakey, commissioner of the Texas Department of State Health Services, said the state's 1,013 reported cases more than double the previous high. Its 40 reported deaths tie the previous high, Lakey said in a telephone news briefing.

More cases and deaths have been recorded at the local level but not yet reported to the state.

"As of this week, 2012 is now officially our worst year in the state of Texas for West Nile," Lakey said during the briefing held by U.S. health officials.

Neither Lakey nor a leading U.S. Centers for Disease Control and Prevention official could explain why Texas has been so hard hit. Dr. Kyle Petersen, a West Nile specialist for the CDC, said the agency would look carefully at that question at the end of the season.

Lakey said state health officials are seeing signs that the mosquito-borne outbreak may have peaked in the northern part of Texas, the area by far the hardest hit. But he added that the number of cases and deaths in the state will keep rising at least into October.
Second person in McLennan County dies from West Nile Virus
Posted: Oct 26, 2012 8:35 PM GDT


MCLENNAN COUNTY - The Waco-McLennan County Public Health District has confirmed a second death caused by the West Nile Virus. An 82-year-old woman was diagnosed with West Nile Virus in September and died on Thursday.

There have been no new reports of West Nile Virus since October 2, and with cooler temperatures looming mosquitoes are typically less active. However, the Health District says mosquitoes are still present and have the potential to bite people and spread the virus.

The Health District strongly encourages everyone to continue to use mosquito repellant, with DEET, as needed on exposed skin and clothing.
