Mexico is facing an active measles outbreak across all 32 states. What it is, how it spreads, its symptoms, and why vaccination remains the only way to prevent it.
Measles is an extremely contagious viral disease that primarily affects the respiratory tract before spreading through the rest of the body. It spreads through respiratory droplets from coughing and sneezing, and an infected person can pass it on to others from four days before to four days after the characteristic rash appears.
Mexico is currently facing an active outbreak that has reached all 32 states, with Chihuahua, Jalisco, Chiapas, Michoacán and Guerrero among the states with the highest case counts. Health authorities attribute the rise mainly to declining vaccination coverage and incomplete immunization schedules among children.
Symptoms usually appear 7 to 12 days after exposure, in two stages. The first includes high fever, runny nose, red and watery eyes, white spots inside the mouth, and a persistent dry cough. Days later comes the eruptive stage: the fever briefly drops and rises again before a red rash appears, starting on the face and spreading to the rest of the body, along with general malaise.
While most uncomplicated cases resolve with adequate rest and hydration, measles can lead to serious complications — especially in infants under one year, pregnant women, and people with weakened immune systems: severe dehydration, ear infections, pneumonia, brain swelling, and even death. There is no specific antiviral treatment for measles; care focuses on relieving symptoms and preventing complications.
The MMR vaccine, which protects against measles, mumps and rubella, remains the only proven way to prevent the disease. Mexico's recommended schedule is a first dose between 12 and 23 months of age, with a booster at age 6; during active outbreaks, an additional dose can be given to children under 5. The vaccine is available at no cost through IMSS, IMSS-Bienestar, ISSSTE, and state health centers.
If you have symptoms consistent with measles, you should seek care at a health center right away, avoid contact with others until a diagnosis is confirmed, rest, stay hydrated, and avoid self-medicating.
