Female Asian tiger mosquitoes:

  • are not strong fliers, they stay near their breeding sites.
  • prefer to bite ankles and the lower leg. Don't forget to protect these areas with repellents.
  • also bite around the head, neck, and arms.

The Centers for Disease Control advises everyone, especially in the Southern states to protect themselves from mosquito bites by using repellents containing 1 of 4 active ingredients: DEET, Picaridin, Oil of lemon eucalyptus, or IR3535 and protective clothing.

According to the U.S. Zika response plan, Zika transmission is defined as two or more cases not due to travel or sex with an infected person that occur in a 1 mile diameter over the course of a month.

Morbidity and Mortality Weekly Report publication:Contraceptive Use among non-Pregnant and Postpartum Women at Risk for Unintended Pregnancy and Female High School Students, in the Context of Zika Preparedness — United States, 2011—2013 and 2015. 8/3/16.

CDC scientists used data from four state-based surveillance systems to estimate contraception use for non-pregnant and postpartum women at risk for unintended pregnancy, and sexually active female high school students, who live in states with the potential for local Zika virus transmission.

Main findings:
• About 1 in 3 women at risk for unintended pregnancy are not using any birth control method.
• Use of long-acting reversible contraception (LARC including intrauterine devices and implants)—the most effective method to prevent unintended pregnancy—remains lower than use of moderately and less effective reversible contraceptives such as pills and condoms.
• Moderately effective and less effective contraceptive methods, including pills, patches, rings, injections, condoms and other barrier methods, were used more frequently than highly effective methods across all age groups and race/ethnicity.

New peer reviewed paper:Prolonged Detection of Zika Virus RNA in Pregnant Women. Obstetrics & Gynecology. 1 August 2016 8/3/16.

CDC’s latest report in Obstetrics & Gynecology highlights the experience of five pregnant women infected with Zika virus who had evidence of Zika virus in their blood longer than is typically expected. CDC scientists raise important questions about what this finding might mean — whether it is unique to pregnant women and if so, whether it is linked to poor pregnancy or birth outcomes.
Main Findings:
• Four pregnant women with signs or symptoms consistent with Zika virus disease and one pregnant woman without symptoms had evidence of Zika virus in their blood for longer than expected (mean duration viral RNA is detectable in serum was approximately 10 days).
o Four pregnant women with symptoms had evidence of Zika virus in their blood up to 46 days after they had symptoms.
o One pregnant woman without symptoms had evidence of Zika virus in her blood at 53 days after last date of possible exposure.
• One pregnant woman had evidence of infection in her fetus. Three of the pregnancies are complete and one is ongoing.

Frequently asked questions about mosquitoes and Zika in Kentucky.

Aedes aegypti mosquitoes are more likely to spread viruses like Zika, dengue, chikungunya, and other viruses than other species of mosquitoes. Fortunately, it is very rare in Kentucky. The map below shows the Centers for Disease Control (CDC's) estimated range of Aedes aegypti based on where it occurs or has previously been found.

Estimated range of Aedes aegypti in the US (CDC 2016)

Aedes albopictus, the Asian tiger mosquito (ATM), occurs throughout the state and is a species of importance should local transmission occur in Kentucky. The ATM is an outdoor (garden) mosquito that breeds in most any water-filled container. It is an aggressive, day-biter that will feed on humans and a variety of available domestic and wild vertebrates. It is primarily active late afternoon through early evening although it has a secondary period of activity around dawn. It is responsible for most of the mosquito bites that occur in Kentucky city suburbs.

Estimated range of Aedes albopictus in the US (CDC 2016)

These maps represent the CDC's best estimate of the range of these two species in the US. They are not meant to represent the risk for spread of disease.
