Background on the Influenza H3N2 Variant
The World Health Organization (WHO) issued an alert regarding the circulation of the H3N2 influenza variant, also known as “super flu,” in Europe and the United States. However, David Kershenobich, Mexico’s Federal Secretary of Health, reported that only one case has been registered in Mexico and there is currently no significant health risk for the country.
Understanding the H3N2 Variant
Kershenobich explained that the H3N2 variant is not new or extraordinary; it’s a subclassification of the influenza virus already covered by the seasonal vaccine available in Mexico. He emphasized that vaccination not only prevents infections but also significantly reduces severe cases and hospitalizations.
The Single Case in Mexico
Kershenobich Stalnikowitz detailed that the single case involved a 40-year-old man from Mexico City who did not require hospitalization and exhibited a typical seasonal influenza clinical presentation. Currently, there are no individuals infected or hospitalized due to this variant.
Contagiousness and Treatment
The secretary highlighted that the H3N2 variant is more contagious but responds well to standard treatments, including oseltamivir. He assured that there is ample supply of this medication in the public health system.
Seasonal Influenza Vaccine Availability
Kershenobich pointed out that the seasonal influenza vaccine for 2024-2025 is entirely produced in Mexico, and there are sufficient doses to cover the at-risk population.
