West Nile Virus has made its first appearance of the season in a human in California.

The season's first two cases of West Nile Virus have been reported. 

"The first is a human case who resides in Contra Costa County who was recently hospitalized and since recovered. The second resides in San Joaquin County and has tested positive but has not developed symptoms of West Nile virus," Dr. Carrie Padgett of the Public Health Department said. 

Padgett says it's a reminder to protect yourself from mosquito bites.

"Apply insect repellent containing DEET. Repellents keep the mosquitoes from biting you, and DEET can be used safely on infants and children two months of age or older," Padgett said. 

While the risk to most people is low, West Nile virus can lead to serious illness like encephalitis or meningitis.  

If you're over 50 you have a higher chance of getting sick, and you're more likely to develop complications.  

So far this year, West Nile Virus has been detected in mosquitoes and birds in 19 California counties.
