HOUSTON – As rain continues to move across the Houston area, health officials are warning that the wet weather is also creating the perfect breeding ground for mosquitoes.
The Texas Department of State Health Services confirmed the first human case of West Nile virus in Texas this year was reported in Harris County.
According to DSHS, the resident was diagnosed with West Nile neuroinvasive disease — the most serious form of the virus that can affect the brain and nervous system.
“West Nile and other mosquito-borne illnesses are a fact of life in Texas in the warmer months, and all Texans should take precautions against mosquito bites to stay safe and healthy,” DSHS Commissioner Dr. Jennifer Shuford said in a statement.
Health officials say most people infected with West Nile virus never develop symptoms. However, about 20% can experience what’s known as West Nile fever.
Common West Nile symptoms include:
Fever
Headache
Body aches
Fatigue
Rash
Less than 1% of infected people develop neuroinvasive disease, which can cause severe neurological complications including:
Tremors
Convulsions
Neck stiffness
Paralysis
Disorientation
State health leaders say preventing mosquito bites is the best way to reduce the risk of infection.
