HOUSTON - A second human case of West Nile virus has been confirmed in Harris County.
A northwest Harris County 15 to 24 year old male has been diagnosed with the virus. He is expected to recover.
The first case was of a northeast Houston woman between the ages of 55 and 74 who may have a pre-existing health condition.
Some of the symptoms of West Nile virus include headaches, body aches and fever.
"We're starting to see an increase in the number of mosquitoes that are actually infected with West Nilevirus ," said Rudy Bueno, director of the Harris County Mosquito Control Division.
Officials said there have been four confirmed cases of West Nile virus in birds in Harris County.
Recent rains have created a breeding ground for mosquitoes.
Health experts recommend using plenty of repellent.
Most people become infected within three to 10 days of a bite from an infected mosquito.
