First Mosquitoes Testing Positive for West Nile Virus Reported
The Illinois Department of Public Health (IDPH) has confirmed the first mosquitoes to test positive for West Nile virus in Illinois for 2020. The Des Plaines Valley Mosquito Abatement District collected a positive mosquito batch on May 31, 2020 from River Forest, Illinois, and North Shore Mosquito Abatement District collected a positive mosquito batch on June 5, 2020 in Evanston, Illinois. No human cases of West Nile virus have been reported so far this year.
Ford County Public Health Department is urging residents to be aware of West Nile virus activity in their area and take steps to protect themselves and their family from West Nile virus and other mosquito borne diseases.
West Nile virus is transmitted to people by infected mosquitoes. Seasonal outbreaks often occur in local areas that can vary from year to year. Many factors impact when and where outbreaks occur, such as weather, numbers of mosquitoes that spread the virus, and human behavior.
The best way to prevent West Nile virus disease is to avoid mosquito bites and to practice the three “R’s” – Reduce, Repel, Report:
Approximately 1 in 5 people who are infected with West Nile virus will develop symptoms such as fever, headache, body aches, joint pains, vomiting, diarrhea, or rash. Less than 1 percent will develop a serious neurologic illness such as encephalitis or meningitis (inflammation of the brain or surrounding tissues). About 10 percent of people who develop neurologic infection due to West Nile virus will die. People over 50 years of age and those with certain medical conditions, such as cancer, diabetes, hypertension, kidney disease, and organ transplants, are at greater risk for serious illness.
There are no medications to treat, or vaccines to prevent, West Nile virus infection. People with milder illnesses typically recover on their own, although symptoms may last for several weeks. In more severe cases, patients often need to be hospitalized to receive supportive treatment, such as intravenous fluids, pain medication, and nursing care. Anyone who has symptoms of concern should contact a health care provider.
