Orange County health officials have confirmed the first case of Human West Nile virus this year.
The announcement, issued by the Orange County Health Care Agency on Wednesday, stated a Huntington Beach resident tested positive for the virus. The exact date of their positive test was not released.
According to the county’s Deputy Health Officer Dr. Matthew Zahn, more positive cases may be reported in the coming weeks.
“West Nile Virus regularly occurs in Orange County during the summer months and into the fall…and with increased WNV activity reported by our partners at O.C. Vector Control, we anticipate that additional human cases may be reported in the coming weeks,” Zahn stated. “We encourage everyone to take precautionary measures to avoid mosquito bites as the best way to avoid West Nile Virus infection.”
There were seven reported positive West Nile virus cases in 2023.
Some of the recommended West Nile virus precautions include:
- Emptying all standing water to reduce areas in which mosquitoes may breed, such as flower pots and pet bowls
- Making sure window and door screens are in good condition
- Using insect repellent that contains DEET, picaridin, oil of lemon eucalyptus or products containing IR3535
- Limiting outdoor activity at dusk and dawn when mosquitoes are most active
- Wearing long sleeves and long pants when outdoors, if possible
O.C. health officials are cautioning residents that while “most people” who contract West Nile virus do not experience symptoms, about two in 10 will experience symptoms, including a fever, headache, body aches, nausea, tiredness and occasionally a skin rash.
More severe symptoms include severe headaches, neck stiffness, confusion, muscle weakness or paralysis. These occur more rarely, officials said, but anyone with those symptoms is urged to seek medical care immediately.
