After investigating 50 of those travelers, the CDC was able to determine that measles spread during air travel in at least one of those situations, the spokesperson said. That is usually based on connecting confirmed cases of measles among airline passengers sitting near each other.

As measles cases surge in the U.S. and around the globe, the CDC is issuing new guidance to travelers, encouraging them to get vaccinated for the disease and postpone travel plans if they have not done so yet.

The Centers for Disease Control and Prevention is warning people about the risks of contracting measles while traveling.

In a Substack post, Paul Offit, MD, a vaccine expert at the Children's Hospital of Philadelphia, noted how unusual it was that HHS Secretary Robert F. Kennedy Jr. would "unilaterally eliminate" COVID shots from the childhood immunization schedule -- "without input from vaccine advisory committees and without allowing for public comment."

The CDC’s new Covid-19 recommendations are the first time that Robert F. Kennedy Jr. has narrowed access to vaccines in the U.S.

Africa CDC has managed the mpox response through an Incident Management Support Team (IMST) jointly led by Africa CDC and the World Health Organization, working with 26 other partners, including UNICEF, the International Committee of the Red Cross, and Gavi, the Vaccine Alliance.

NewsNation has obtained a letter from the CDC sent to hospitals and health care providers after the 2023 train derailment in East Palestine, Ohio.

Robert F. Kennedy Jr. said in a social media video that the U.S. would no longer recommend Covid-19 vaccines to children and pregnant women. The CDC has yet to make the policy official.
