CDC: West Nile Illness Surging This Year
Cases of West Nile illness are being reported at about triple the usual rate, U.S. health officials say. The Centers for Disease Control and Prevention (CDC) said there have been 1,118 human cases so far in 2012. About half have been in Texas. In a typical year, the CDC said, fewer than 300 cases are reported by the middle of August. Most cases are reported in August and September. CDC officials suggested that the mild winter, early spring and very hot summer have spurred breeding of the mosquitoes that carry the disease. They spread it by biting infected birds and then biting humans or other animals. Only 1 person out of 5 gets sick from the infection. Symptoms usually are mild. About 1 person out of 150 has a serious illness. The most severe symptoms include neck stiffness, paralysis and coma. The Associated Press wrote about the outbreak August 22.
