Travel Vaccination Recommendations
There are no vaccinations required when traveling to Costa Rica from the US but the CDC recommends that your usual vaccinations – measles-mumps-rubella, varicella [chickenpox], polio, tetanus and influenza - be current. It also advises people to get vaccinated against Hepatitis A and typhoid which are acquired through contaminated water and/or food. While San Jose has an excellent infrastructure and the water is safe to drink, the risk increases when you travel to more rural areas. Malaria prevention is not a current recommendation. People, who plan to work with animals, get a tattoo or “exchange body fluids” should also consider a Hepatitis B vaccination and, possibly, a rabies vaccination.
The Zika virus which is spread by mosquitoes is in Central and South America including Costa Rica. Most people, if they got it, would experience symptoms similar to a common cold and not even realize that they had it. The danger with Zika is that it can cause birth defects and, consequently, the recommendations are for pregnant women to not travel to Costa Rica, for women to not get pregnant for up to six months after traveling to Costa Rica and to not get pregnant for up to six months from a partner who has traveled to Costa Rica.
