Measles Warning Updated by CDC
The Centers for Disease Control and Prevention (CDC) has updated its warning about the risk of contracting measles, particularly for travelers. This update comes after the agency received reports of infectious travelers flying in the USA this year.
Risk of Measles in Travel Environments
Travelers can catch measles in various environments, including airports, train stations, public transportation, tourist attractions, and large, crowded events. Since the beginning of the year, the CDC has received at least 62 reports from travelers who were contagious with the highly transmissible virus during flights to or within the USA.
Investigation and Findings
After examining 50 of these travelers, the CDC found that measles spread in at least one of these situations during flights. This is usually determined by connecting confirmed cases of measles among airline passengers sitting near each other. There have also been numerous public notifications about the possible risk of exposure to measles at airports after travelers were found to be contagious.
Updated List of Countries with High Measles Incidence
The CDC has updated its list of countries with high measles incidence. Instead of listing specific countries, the agency now warns that the virus is an ongoing risk worldwide and that more international travelers are being infected. Neighboring countries, including Mexico and Canada, have also reported significant measles outbreaks.
Recommendations for Travelers
The CDC recommends that all travelers be vaccinated against measles before going to an international destination. The agency has also updated its guidance for doctors to advise on additional measles vaccines for some domestic travelers. Travelers should consider postponing their trip if they are not vaccinated.
Measles Cases in the USA
At least 1,088 cases of measles have been reported in the USA so far this year, with two other countries – Iowa and Nebraska – now reporting their first confirmed cases. Around 90% of the confirmed cases are connected to outbreaks in the USA and do not involve travel outside the country.
Ongoing Risk of Measles
While federal health officers have declared that the current outbreak seems to be slowing down, they have warned of the risk of another spread driven by travel. The affected states remain hypervigilant, particularly during the travel season. The CDC continues to monitor the situation and provide updates on the risk of measles for travelers.
