West Nile virus numbers down big compared to 2012, Texas most dramatic difference

New data recently released by the US Centers for Disease Control and Prevention (CDC) shows that the number of cases and deaths due to West Nile virus (WNV) in 2013 are down significantly compared to the same time frame in 2012.

West Nile virus Transmission cycle

As of Sept. 24, the federal health agency is reporting 1,135 cases across the country, with 44 fatalities.

In 2012, the CDC reported 3,969 cases of West Nile virus disease in people, including 163 deaths on Oct. 2.

In all of 2012, there were a total of 5,674 WNV cases and 286 deaths. The 2012 numbers were the highest for West Nile since 2003.

Clearly, the most dramatic difference in a state between 2012 and 2013 in WNV cases is Texas. Last year, the Lone Star state recorded an astounding 1,868 cases with 89 fatalities.

With three months left in 2013, Texas has reported a paltry (compared to last year) 62 cases and four deaths to date.

According to the CDC, WNV is most commonly transmitted to humans by mosquitoes. You can reduce your risk of being infected with WNV by using insect repellent and wearing protective clothing to prevent mosquito bites. There are no medications to treat or vaccines to prevent WNV infection.

Fortunately, most people infected with WNV will have no symptoms. About 1 in 5 people who are infected will develop a fever with other symptoms. Less than 1% of infected people develop a serious, sometimes fatal, neurologic illness.
