There are four confirmed cases of measles in Mexico City


The wake-up call came with the announcement that a girl of only eight years had a confirmed diagnosis of Measles. Located in Álvaro Obregón, the girl had the first dose of the measles vaccine, but the booster was never applied.

How could it be otherwise, an instrumented health operation immediately traveled 25 blocks around where the child lives, to locate possible infections and apply vaccines. There was no luck in finding the source of infection, but on the night of March 4, three other cases were confirmed in the Gustavo Madero delegation.

Now it is a boy of 10 years, and two men of 37 and 39 years respectively. None of them had the measles vaccine.

Measles has not been completely eradicated in Mexico. Just in 2019, 20 cases were registered in total, none in CDMX; in Mexico, they have not registered native cases since 1996.


The best protection is the triple viral vaccine, although according to the secretary of health of CDMX, Olivia López Arellano, there has been a decrease in access to vaccines in the capital from 2010 to 2018. According to the official, schemes have been initiated vaccination in children one year from 2019.

López estimated that from 2010 to 2018 there was a 20% decrease in access to vaccines, although he assured that by 2019 there was a slight rebound of 3% .1997 was the first year without measles in Mexico

Mexico has experience with measles. The last epidemic of the disease occurred between 1989 and 1990 when 89,163 cases were reported. From 2010 to 2019, 185 cases associated with imports were identified. However, as of 2018, there is a rebound in the world of measles, mainly due to a downward trend in vaccination according to the Ministry of Health. In an epidemiological report of 2019, it is said that to avoid the reintroduction of measles it is essential to guarantee vaccination coverage of 95% at the municipal level.

The measles vaccine in the case of children is the triple viral, which also serves to prevent mumps and rubella, and which is known as MMR. Its first application, to children under 12 to 15 months of age, reached minimum historical levels in 2017, when reported, according to data from the Pan American Health Organization, a coverage of 79%. Worse, the reinforcement applicable to children 4 to 6 years of age is only 62%.

If it is only about reinforcement, Mexico is in 34th place of 37 countries supervised by Paho in terms of MMR coverage. In 2016 Mexico was in fifth place, with MMR2 coverage of 98%. For adolescents and adults, the measles vaccine is the double viral (SR) that can be found in IMSS clinics and health centers. It should not be applied to pregnant women in their first trimester.

Measles is one of the leading causes of death among children, according to the World Health Organization. It is a disease caused by a virus that is transmitted through invisible droplets of saliva and that accompany exhalation. Symptoms include fever, cough, nasal discharge, conjunctivitis, and the characteristic skin rash.
