Case of West Nile virus confirmed in San Bernardino

The San Bernardino County Department of Public Health confirmed last week that one of the first locally acquired human cases of West Nile virus for the year was contracted in San Bernardino and issued a warning to residents.

“West Nile virus can cause a serious illness in humans. Therefore, I urge residents to take precautions to protect themselves against mosquito bites” said San Bernardino County Health Officer Michael A. Sequeira, M.D.

West Nile virus is transmitted to humans through the bite of an infected mosquito. Signs and symptoms of the virus may include fever, body aches, rash, nausea, vomiting, and headache.

Most people infected with the virus have no symptoms. However, people 50 years of age and older and individuals with diabetes, hypertension, who are immunocompromised or have a recent history of chemotherapy have a higher chance of getting sick and are more likely to develop complications.

The most effective way to avoid West Nile virus is to prevent mosquito bites.

If you experience a sudden high fever (above 102°F), severe headache, or a stiff neck, seek medical help right away.

The risk of infection due to West Nile virus typically increases from summer through early fall. Residents are encouraged to protect themselves from mosquito bites during outdoor activities, especially at dawn and dusk.
