Measles in the USA

24 Feb 2025

From 1 January to 20 February 2025, the Centres for Disease Control and Prevention (CDC) reported a total 93 measles cases in 8 States: Alaska, California, Georgia, New Jersey, New Mexico, New York City, Rhode Island, and New Mexico.

These numbers will increase as measles outbreaks are ongoing in New Mexico and Texas.

Measles is a highly infectious viral disease spread through sneezing, coughing or direct contact with respiratory fluids. It causes a rash, high temperature (fever) and muscle aches and can have serious complications.

Advice for Travellers

Travelling abroad may increase your risk of measles. Your risk of exposure may be higher if you will be visiting friends and relatives and/or mixing with the local population during your trip.

Two doses of measles vaccine (given as part of MMR in the UK) are needed in your lifetime to fully protect you.

Check with your GP before travelling to ensure you have received two doses of MMR vaccination.

Children should be up to date with the UK Vaccination Schedule. This includes a dose of MMR vaccine at around 12-13 months, and a second dose usually given from 3 years 4 months of age.

• If your child has not yet had 2 doses of the MMR vaccine, talk to your GP or travel health professional as they may be able to have the vaccine earlier than normal if you are travelling to an area considered to have a high risk of exposure to measles.
