ST. AUGUSTINE, FL.—  The Florida Department of Health in St. Johns County (DOH-St. Johns County), in partnership with the Anastasia Mosquito Control District (AMCD), advises residents and visitors of an increase in mosquito-borne disease activity within the south east quadrant of St. Johns County. One human case of locally acquired West Nile Virushas been confirmed and there is a heightened concern that additional residents may become ill. The public should remain diligent in preventative measures like “Drain and Cover.”

In recent weeks, sentinel chicken flocks tested positive for West Nile virus. Additionally, West Nile Virus infection was detected in the death of one horse. The risk of transmission of mosquito borne illness to humans has increased. DOH-St. Johns County and AMCD continue ongoing surveillance and prevention efforts.

To avoid being bitten by mosquitoes and to limit exposure, residents and visitors are reminded to “Drain and Cover”:

DRAIN  standing water to stop mosquitoes from multiplying.

  • Drain  water from garbage cans, house gutters, buckets, pool covers, coolers, toys, flower pots or any other containers where sprinkler or rain water has collected.
  • Discard  old tires, drums, bottles, cans, pots and pans, broken appliances, and other items that aren't being used.
  • Empty and clean  birdbaths and pet's water bowls at least twice a week.
  • Protect  boats and vehicles from rain with tarps that don’t accumulate water.
  • Maintain  swimming pools in good condition and appropriately chlorinated. Empty plastic swimming pools when not in use.

COVER  skin with clothing or repellent.

  • Clothing - Wear shoes, socks, and long pants and long sleeves. This type of protection may be necessary for people who must work in areas where mosquitoes are present.
  • Repellent - Apply mosquito repellent to bare skin and clothing.
    • Always use repellents according to the label directions. Repellents with DEET, picaridin, oil of lemon eucalyptus, para-menthane-diol, 2-undecanone and IR3535 are effective.
    • Use mosquito netting to protect children younger than 2 months old.

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, 2-undecanone 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 or para-menthane-diol 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.
