Background on the Situation

The World Health Organization (WHO) has raised an alert regarding the circulation of the H3N2 influenza variant, colloquially known as the “super flu“, in Europe and the United States. In response, Mexico’s Secretary of Health, David Kershenobich, reported that only one case has been registered in Mexico, dismissing any immediate health risk to the country.

Understanding the H3N2 Variant

During Claudia Sheinbaum’s morning press conference, Kershenobich Stalnikowitz clarified that the H3N2 variant is not new or extraordinary but a subclassification of the influenza virus. He emphasized that this variant is already covered by the seasonal vaccine available in Mexico. The official highlighted that vaccination not only prevents infections but also significantly reduces severe cases and hospitalizations.

Contagiousness and Treatment

Kershenobich Stalnikowitz explained that the H3N2 variant is more contagious but responds well to standard treatments, including oseltamivir. He assured that there is sufficient stock of this medication in the public health system.

“At present, there is no problem for the country; it remains under epidemiological surveillance,” he affirmed.

Vaccine Production and Distribution

The Secretary of Health stressed that the influenza vaccine for the 2024-2025 season is entirely produced in Mexico and that there are enough doses to cover the at-risk population.

Additionally, those with chronic conditions such as diabetes, hypertension, obesity, asthma, pulmonary diseases, or any condition compromising the immune system should be protected.

Current Vaccination Coverage and Call for Action

Currently, Mexico has nearly 50% vaccination coverage. The Secretary of Health urged the population to visit health centers for vaccination, stating, “The best health system focuses on prevention. We have the vaccine and treatment.”
