Rabies

Dogs infected with rabies are not commonly found in Portugal.If rabies exposures occur while in Portugal, rabies vaccines are typically available throughout most of the country.Rabies pre-exposure vaccination considerations include whether travelers 1) will be performing occupational or recreational activities that increase risk for exposure to potentially rabid animals and 2) might have difficulty getting prompt access to safe post-exposure prophylaxis.Please consult with a healthcare provider to determine whether you should receive pre-exposure vaccination before travel.For more information, seecountry rabies status assessments.
