The Centers for Disease Control and Prevention (CDC) issued a new travel alert yesterday for Brazil due to an outbreak of measles.

As of August 4, 2018, health officials in Brazil have reported over 5,000 cases of measles, of which more than 1,000 are confirmed. The majority of cases continue to be reported in the states of Amazonas and Roraima.


In Amazonas State, all reported cases are Brazilian nationals and over 1,800 cases were reported in children less than 9 years old.

Travelers to Brazil, and the state of Amazonas in particular, should make sure they are vaccinated against measles with the MMR (measles, mumps, and rubella) vaccine before travel.

PAHO calls for rapidly increasing measles vaccination coverage in Latin America

What can travelers do to protect themselves?

  1. Make sure you are fully vaccinated or otherwise protected against measles.
  2. People who cannot show that they were vaccinated or are otherwise protected against measles should get vaccinated before leaving the United States:
    • Infants (6 through 11 months of age) should have 1 dose of MMR vaccine.
    • Adults and children over 1 year of age should have 2 doses of MMR vaccine separated by at least 28 days.
  3. Avoid contact with people who are sick.

Measles is a disease that can lead to serious complications, such as pneumonia (infection of the lungs), and even death. It is caused by a highly-contagious virus that is spread through the air by breathing, coughing, or sneezing. Signs and symptoms of measles include rash, high fever, and a cough, runny nose, or red, watery eyes.
