New Measles Variant Sparks Alerts
New Measles Variant Sparks Alerts
The discovery of a more aggressive measles variant in Europe has set off alarms worldwide.
Vaccination remains the main weapon against measles – don’t let your guard down!
Measles, a disease that seemed under control thanks to vaccination, has re-emerged with a vengeance in Europe, and what is even more worrying, with a more aggressive variant. Experts have detected a significant increase in cases, some of which have serious and even fatal complications. The World Health Organization (WHO) has issued an alert, urging countries to strengthen their immunization programs.
The measles variant in question is genotype B3, which has been linked to outbreaks originating in Morocco, where cases have been reported since September 2023. Its detection in wastewater in cities such as Brussels has set off alarm bells.
Why is it so dangerous?
This new variant of measles has a greater capacity for transmission and can cause more severe complications, especially in young children, pregnant women and people with weakened immune systems. Complications include pneumonia, brain inflammation and blindness.
Could it reach the United States?
Globalization and the constant flow of people between countries increase the risk of this variant reaching the United States. In fact, isolated cases have already been reported in certain regions of the country, indicating that the threat is real.

What can we do?
Vaccination is the best protection. The Centers for Disease Control and Prevention (CDC) recommends that all children receive two doses of measles, mumps and rubella (MMR) vaccine. Adults who are unvaccinated or who have not had measles should also be vaccinated.
In addition, it is important to take the following measures:
– Maintain hygiene: wash hands frequently and cover mouth and nose when coughing or sneezing.
– Avoid contact with sick people: If someone in your household has measles, stay away from them.
– Watch for symptoms: Symptoms of measles include high fever, rash, cough, runny nose and red eyes. If you or someone you know has these symptoms, seek medical attention immediately.
