The U.S. Centers for Disease Control and Prevention (CDC) has issued a travel advisory for Zika-affected countries in the Americas. The CDC recommends pregnant women consider postponing non-essential travel or consult with a doctor to discuss specific risk factors before traveling. Zika has been reported in some Caribbean and Latin American destinations.
What is Zika Virus?
Zika virus is a mosquito-borne disease closely related to dengue fever, chikungunya, and West Nile virus. The virus can be spread from mosquito to human. Recent studies have shown that pregnant women who are infected can pass the virus to their unborn child. Cases of poor pregnancy outcomes and serious birth defects such as microcephaly have been reported.
How can I Protect Myself?
If you are planning a trip to any Zika-affected country, follow these guidelines:
- Discuss the relative threat of Zika virus infection with your doctor. This is especially important if you are pregnant or may become pregnant while traveling.
- Use insect repellent containing at least 20% DEET. Non-DEET alternatives are also available - such as picaridin, oil of lemon eucalyptus, or IR3535. Be sure to follow the specific instructions on the repellent you use, to make sure that you maintain protection at all times.
- Wear long sleeves, pants, socks, and hats to cover as much skin as possible while comfortable. The more skin you cover with clothing, the less opportunity disease-carrying mosquitoes have to bite you. Clothing can also be treated with permethrin to provide additional protection against mosquitoes.
- Prevent mosquitoes from coming indoors. Whenever possible, stay in rooms that are air-conditioned or that have intact window and door screens. Routinely check rooms for mosquitoes, and use indoor insecticide sprays and/or traps to kill any mosquitoes that come inside.
- Monitor yourself for signs of fever, vomiting, or aches and pains. If you get sick while traveling in a Zika-affected area or shortly after returning home - especially if you were pregnant during your trip or suspect you might have become pregnant - seek medical attention, and be sure to inform your doctor that you may have been exposed to Zika virus.
