The West Nile Virus, which appeared on the East Coast in 1999, has now spread to multiple states and has affected multiple species of animals, including two cats. Of the 18 human cases, one person has died. Other mammals include 14 bats, three rabbits, three squirrels, two raccoons, two cats, one skunk, and one chipmunk. Confirmed cases were also found in blue jays and at least one raven.
Mosquitoes transmit the virus to people and animals when taking a blood meal.
In humans, people over 50 years of age have the highest risk of developing severe illness. People with compromised immune systems are also at risk, however, anyone can get the virus. The symptoms of mild infections in humans include fever, headache, and body aches, often with skin rash and swollen lymph glands. Headache, high fever, neck stiffness, stupor, disorientation, coma, tremors, occasional convulsions, and paralysis mark more severe infections. There is no specific treatment for animals or people with West Nile Virus.
