The Texas Department of State Health Services (DSHS) reported today that the number of human West Nile virus (WNV) cases has increased by 11 during the past several days, bringing the total confirmed cases to 41.
Of the 41 cases reported to date, 60 percent (25) have been of the more serious neuroinvasive disease.
Montgomery County has seen the most cases at 13, followed by Harris County with eight and Dallas County with five.
In 2013, Texas reported 183 WNV cases, dramatically down from the 1,868 cases reported in 2012.
West Nile virus is a mosquito-borne illness. Up to 80 percent of people infected with West Nile virus will have no symptoms. However, some infections can result in serious illness or death.
People over 50 years of age and those with weakened immune systems are at a higher risk of becoming seriously ill if they become infected with the virus. For more infectious disease news and information, visit and “like” the Infectious Disease News Facebook page
