A strain of influenza, dubbed the “super flu,” has officially arrived in Mexico. Health authorities confirmed the country’s first case of the H3N2-K variant, a subtype of influenza A, was identified on December 12.
According to the federal Department of Health, the infected individual has since recovered following a course of antiviral treatment.
Hospitals in the United Kingdom, however, have reported increased admissions linked to the virus, and cases have also been identified in the United States and Canada. In response, airports are heightening health screenings to prevent further cross-border transmission.
Symptoms
Although symptoms mirror those of a common cold, health experts emphasize a critical difference: the onset of H3N2 influenza is typically abrupt and more intense.
The primary symptoms include:
- Sudden high fever
- Persistent dry cough lasting several days
- Sore throat and nasal congestion
- Widespread headache and muscle pain
- Debilitating fatigue beginning in the first hours
- Chills and sweating
Experts have point outed that a cold usually begins gradually, with mild discomfort, sneezing and predominant nasal congestion, while influenza begins with high fever and more severely affects the ability to perform daily activities.
Though H3N2 is a known seasonal virus, this particular variant can lead to serious complications for vulnerable groups. Health officials are urging heightened caution for:
- Pregnant women
- Children under 5 and adults over 65
- Individuals with chronic conditions (heart, lung, kidney, or liver disease)
- Those with metabolic disorders, neurodevelopmental conditions, or blood-related illnesses
The confirmed case has renewed calls from public health advocates to intensify vaccination campaigns ahead of the peak winter season, especially for these high-risk populations.
