Latest Infectious Disease News
THURSDAY, Oct. 25 (HealthDay News) -- The number of West Nile virus cases this year has surpassed 4,700, U.S. health officials reported Thursday, and the number of deaths has reached 219, up from 183 last week.
As of Tuesday, 48 states had reported West Nile infections in people, birds or mosquitoes. A total of 4,725 cases involved people. Of these cases, 51 percent were classified as neuroinvasive disease (such as meningitis or encephalitis) and 49 percent were classified as non-neuroinvasive disease.
The 4,725 cases mark the highest number reported through the fourth week of October since 2003. The bulk of reported cases (3,215) were from eight states -- Texas, California, Louisiana, Mississippi, Illinois, South Dakota, Michigan and Oklahoma -- and the highest number of reported cases (1,628) in any one state were in Texas, according to the U.S. Centers for Disease Control and Prevention.
The best way to avoid the 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:
