Indian River County —The Florida Department of Health in Indian River County (DOH-Indian River) and Indian River Mosquito Control District (IRMCD) continue to warn residents about the continued increase in mosquito-borne disease activity in Indian River County.

Several sentinel chickens have tested positive for West Nile virus (WNV) infection. No human infections with WNV have been identified in Indian River County at this time, but the risk of transmission to humans has increased. Indian River Mosquito Control District and DOH-Indian River continue surveillance and prevention efforts.

DOH-Indian River and IRMCD want to emphasize the importance of residents and visitors protecting themselves against mosquito-borne diseases. Because of our climate on the Treasure Coast, there is at least some risk of exposure to mosquito-borne disease throughout the year. Symptoms of West Nile Virus disease may include headache, fever, fatigue, dizziness, weakness and confusion. Physicians should contact their county health department if they suspect an individual may have a mosquito-borne illness.

To reduce mosquito bites, residents are advised to reduce outdoor activities and dusk and dawn, when mosquitoes are most active, wear protective clothing, such as long sleeves and long pants, and apply commercially available repellents according to label directions, repair or replace household screening will help reduce mosquitoes.

Tips on Repellent Use

Always read label directions carefully for the approved usage before you apply a repellent. Some repellents are not suitable for children.

Products with concentrations of up to 30 percent DEET (N, N-diethyl-m-toluamide) are generally recommended. Other U.S. Environmental Protection Agency-approved repellents contain picaridin, oil of lemon eucalyptus, para-menthane-diol, or IR3535. These products are generally available at local pharmacies. Look for active ingredients to be listed on the product label.

Apply insect repellent to exposed skin, or onto clothing, but not under clothing.

In protecting children, read label instructions to be sure the repellent is age-appropriate. According to the Centers for Disease Control and Prevention (CDC), mosquito repellents containing oil of lemon eucalyptus should not be used on children under the age of three years. DEET is not recommended on children younger than two months old.

Avoid applying repellents to the hands of children. Adults should apply repellent first to their own hands and then transfer it to the child’s skin and clothing.

If additional protection is necessary, apply a permethrin repellent directly to your clothing. Again, always follow the manufacturer’s directions.

Cover doors and windows with screens to keep mosquitoes out of your house.

Repair broken screening on windows, doors, porches, and patios.

For more information on what repellent is right for you, consider using the Environmental Protection Agency’s search tool to help you choose skin-applied repellent products:

The Department continues to conduct statewide surveillance for mosquito-borne illnesses, including West Nile virus infections, Eastern equine encephalitis, St. Louis encephalitis, malaria, chikungunya and dengue. Residents of Florida are encouraged to report dead birds via the Florida Fish and Wildlife Conservation Commission’s site - For more information, visit DOH’s website at or contact your county health department.
