Argentina's Mendoza region faces surge in H3N2 influenza cases

Argentina’s health ministry reported a sharp increase in cases of the influenza A (H3N2) "super‑flu" across the country, with the province of Mendoza experiencing the greatest pressure on hospitals and emergency services. Health Minister Rodolfo Montero said the virus is the same strain that circulated previously but has a higher contagion level, describing recent weeks as “quite complicated” for health facilities. The national epidemiological bulletin confirmed a rise in respiratory illness, noting that 23 jurisdictions reported cases, especially the Northwest and Central regions.

Medical experts warned that the situation could develop into a broader outbreak. The Argentine Association of Respiratory Medicine highlighted that the H3N2 subclade K is under international monitoring for its transmissibility and urged accelerated vaccination. In Mendoza, the vaccination campaign started on 3 March, delivering about 5,000 doses daily—significantly above the usual weekly totals. Authorities continue to recommend standard preventive measures such as vaccination for high‑risk groups, mask use, ventilation and avoiding close contact with symptomatic individuals.
