Health officials issue mosquito-borne disease advisory after dengue fever case confirmed

MIAMI- The Miami-Dade County Florida Department of Health (DOH-Miami-Dade) is on a mosquito-borne illness advisory following confirmation of an identified case of dengue fever in a Miami-Dade resident. . This is the first local case of dengue infection in 2022.

Dengue fever is a virus transmitted by mosquito bites by Aedes mosquitoes that also spread chikungunya and Zika virus. Most people infected with dengue have mild or no symptoms. Those who develop symptoms usually recover after about a week.

DOH-Miami-Dade encourages the following mosquito protection efforts to prevent mosquitoes from breeding and to protect your skin by remembering to “Drain and cover.”

DRAIN standing water –

  • Drain water from garbage cans, gutters, buckets, pool covers, coolers, toys, flower pots or any other container where rain or sprinkler water has collected.
  • To throw old tires, drums, bottles, cans, pots and pans, broken appliances and other items that are not in use.
  • empty and clean birdbaths and pet water bowls at least once or twice a week.
  • Protect boats and vehicles from the rain with covers that do not accumulate water.
  • Maintain swimming pools in good condition and suitably chlorinated. Empty plastic pools when not in use.

COVER the skin –

  • Clothes – Wear shoes, socks and long pants and long sleeves. This type of protection may be necessary for people who work in areas where mosquitoes are present.
  • Repulsive – Apply insect repellent to bare skin and clothing, but not under clothing.
    • Always carefully read the instructions on the label for approved use before applying any repellent – Some repellents are not suitable for children.
    • Always use repellents according to the label. Repellents containing DEET, picaridin, oil of lemon eucalyptus, para-menthane-diol and IR3535 are effective.
    • Use a mosquito net to protect children under 2 months.

COVER doors and windows –

  • Repair broken screens on windows, doors, porches and patios to keep mosquitoes out of your home.

Additional tips on using repellents

  • To protect children, read the instructions on the label to make sure the repellent is age-appropriate. According to the Centers for Disease Control and Prevention (CDC), insect repellents containing lemon eucalyptus oil should not be used on children younger than three years old. DEET is not recommended for children under two months of age.
  • Avoid applying repellents to children’s hands. Adults should first apply the repellent to their own hands, then transfer it to the child’s skin and clothes.
  • If additional protection is needed, apply a permethrin-based repellent directly to your clothing. Again, always follow the manufacturer’s instructions.
