In the wake of 10 deaths due to West Nile virus, and hundreds of infections, authorities in Texas are spraying insecticide in the Dallas region, hoping to curb the spread of the disease, which can spread by mosquitoes.
A total of 693 cases of West Nile virus infections, including 26 deaths, were reported as of Aug. 14 to the Centers for Disease Control and Prevention (CDC). The number of cases reported by this second week in August is the highest since 1999, when the disease was first seen in the U.S., according to the CDC.
About 60 percent of this year's cases have involved the "neuroinvasive" form of West Nile infection, in which the nervous system is affected. Such cases can cause inflammation of neural tissues, such as meningitis and encephalitis. More than 80 percent of all reported cases were from six states (Texas, Mississippi, Louisiana, Oklahoma, South Dakota and California), and almost half of all cases have been reported from Texas.
...Early fall is the time of year that mosquitoes tend to have the highest levels of the virus, and human cases tend to peak around this time.
...There is no treatment for West Nile virus infections, according to the CDC.
