Latest Infectious Disease News
WEDNESDAY, Nov. 7 (HealthDay News) -- This year's West Nile virus outbreak has now reached 5,054 cases, including 228 deaths, U.S. health officials reported Wednesday.
As of Tuesday, 48 states plus the District of Columbia had reported West Nile infections in people, birds or mosquitoes. Of the 5,054 cases involving people, 51 percent were classified as neuroinvasive disease (such as meningitis or encephalitis) and 49 percent were classified as non-neuroinvasive disease.
The 5,054 cases mark the highest number reported through the beginning of November since 2003. The bulk of reported cases are from 10 states -- California, Illinois, Louisiana, Michigan, Mississippi, Nebraska, Ohio, Oklahoma, South Dakota and Texas. The highest number of reported cases in any one state is in Texas (1,684 cases, 76 deaths), according to the U.S. Centers for Disease Control and Prevention.
The best way to avoid the mosquito-borne virus is to wear insect repellent and support local programs to eradicate mosquitoes. There is no treatment for West Nile virus and no vaccine to prevent it, according to the CDC.
Typically, 80 percent of people infected with the virus develop no or few symptoms, while 20 percent develop mild symptoms such as headache, joint pain, fever, skin rash and swollen lymph glands, according to the CDC.
Although most people with mild cases of West Nile virus will recover on their own, the CDC recommends that anyone who develops symptoms see their doctor right away.
The best way to protect yourself from West Nile virus is to avoid getting bitten by mosquitoes, which can pick up the disease from infected birds.
The CDC recommends the following steps to protect yourself:
