Avoid Mosquito Bites

Are you planning to travel overseas? Protect yourself and your family from mosquito bites that can make you sick.
Mosquito bites can be more than just annoying and itchy. They can make you really sick. Protect yourself and your family when traveling overseas. Using insect repellent is the best way to prevent diseases like Zika, dengue, and chikungunya that are spread by mosquitoes.


Zika virus is primarily spread to people through mosquito bites. The most common symptoms of Zika virus disease (Zika) are fever, rash, joint pain, or conjunctivitis (red eyes). The illness is usually mild with symptoms lasting from several days to a week. Severe disease requiring hospitalization is uncommon, and deaths from Zika are very rare.

What do Zika, dengue, and chikungunya have in common?

  • Zika, dengue, and chikungunya are spread to people through the bite of an infected Aedes aegypti or Aedes albopictus mosquito.
  • Mosquitoes become infected with Zika, dengue, or chikungunya virus when they bite a person who is infected with one of those viruses. Infected mosquitoes can then spread one of these viruses to other people.
  • There are no vaccines or medicines for these diseases.
  • Once a person is infected with one of these viruses, he or she is likely to be protected from future infections.  
Because Zika can cause birth defects in babies born to women who were infected with Zika virus during pregnancy, CDC recommends the following:
  • Pregnant women should not travel to any area where Zika virus is spreading.
  • Pregnant women who must travel to one of these areas should talk to their doctor first and strictly follow steps to prevent mosquito bites during the trip.
  • Women trying to become pregnant, and their male partners, should consult with their doctor before traveling to these areas and strictly follow steps to prevent mosquito bites during the trip.
  • Zika virus can be spread by a man to his sexual partners. Men who have lived in or traveled to an area with Zika and who have a pregnant partner should either use condoms or not have sex (vaginal, anal, or oral) during the pregnancy.

Forty percent of the world's population lives in an area at risk for dengue and an estimated 390 million people per year are infected with the viruses. Dengue is a disease caused by one of four viruses (dengue virus 1, 2, 3, or 4), and it is possible for someone to get dengue up to four times. Dengue is a leading cause of illness and death in the tropics and subtropics.
Most people infected with dengue have mild or no symptoms. About one in four people who are infected with dengue will develop some symptoms of disease. Mild symptoms of infection begin with a fever and severe headache, pain behind the eyes, joint and muscle pain, and rash. Dengue symptoms can quickly become severe and even fatal. Early recognition of severe disease, followed by close management from a healthcare provider is critical.


The most common symptoms of chikungunya virus infection (chikungunya) are sudden onset of a high fever and joint pain. Other symptoms may include headache, muscle pain, joint swelling, or rash. Infection with chikungunya virus is rarely fatal, but the joint pain can often be severe and debilitating. Most patients recover in about a week, although long-term joint pain occurs in some people. Outbreaks have occurred in countries in Africa, Asia, Europe, and the Indian and Pacific Oceans.
In late 2013, chikungunya virus was found for the first time in the Americas on islands in the Caribbean. Since then, chikungunya has spread to 45 countries and almost 2 million cases have been reported. Though chikungunya is not common in the continental United States, Puerto Rico and the U.S. Virgin Islands have had large outbreaks.
