West Nile Virus

Clark Middleton has died aged 63 after contracting West Nile Virus, and stars who have worked alongside "The Blacklist" and "Twin Peaks" actor have been taking to social media to pay tribute.

Around one in 150 people infected with West Nile virus develop a serious illness.

"Tracking and monitoring the types of mosquitoes that exist in Nebraska communities is critical, which in turn helps us identify potential public health implications and implement prevention measures to reduce risk," a state epidemiologist said.

The deadliest year for West Nile virus so far in the U.S. was 2012, with almost 300 deaths.

There is no vaccine to prevent infection, and there are no medications to treat the virus in people.

West Nile Virus has caused neuroinvasive conditions like meningitis and brain inflammation in 29 people in the U.S.

The virus could cause potentially dangerous health issues in humans and is most commonly spread by mosquitos.

Cases of the disease spread by mosquitos in Los Angeles have risen in the past five years.

Sometimes summer really bites.

Cities around the country are spraying pesticides meant to kill mosquitos that don't work—and could pose a serious health threat.

The new insect would be introduced in the wild to supplant disease carriers with a harmless imposter.
