About West Nile Virus
Age is a risk factor for West Nile virus. People over the age of 50 are at a higher risk for complications from encephalitis and meningitis, the most serious manifestations of the disease, according to the CDC. The CCDPH stated the recent human death case involved an individual in the 70 to 79-year-old age range.
West Nile virus is a potentially serious illness, transmitted to humans through mosquito bites. Those infected experience severe, mild and no symptoms, according to the Center for Disease Control. Most people do not exhibit any symptoms.
Symptoms including fever, headache and body aches can occur three to 15 days after an infected mosquito bite, according to the CCDPH.
Severe symptoms can include high fever, headache, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, vision loss, numbness and paralysis, according to the CDC. Symptoms can last several weeks, and neurological effects may be permanent.
Preventative measures include (source: CDC):
- Get rid of standing water around your home in pet bowls, flowerpots, old tires, baby pools and toys. Water allowed to stagnate for three to four days becomes a breeding ground for mosquitos.
- Check doors and windows have tightly-fitting screens, and repair tears or other openings.
- Keep gutters clean and free of debris, and weeds and grass cut short.
- Cover skin with lightly-colored, lose-fitting clothing when outdoors between dusk and dawn.
Use mosquito repellent with DEET, picaridin or oil of lemon eucalyptus.
