The Ministry of Health of Jujuy has issued a reminder to the public about the importance of maintaining regular preventive measures against respiratory viruses, including staying up to date with vaccination schedules. This comes as part of a national effort to monitor influenza A H3N2, including its K variant.
According to information from the National Ministry of Health, the K variant displays genetic changes that increase its ability to circulate. However, current evidence suggests it does not cause more severe clinical cases compared to other H3N2 variants seen in previous seasons. Between December 18, 2025 and January 9, 2026, there were 11 confirmed cases of this variant reported in Buenos Aires Province, Buenos Aires City, Neuquén, Mendoza, and Santa Cruz.
The symptoms of influenza A H3N2 can include sudden high fever (above 38 degrees Celsius), chills, muscle aches, headache, dry cough, sore throat, nasal congestion and fatigue. Children and older adults may also experience gastrointestinal symptoms such as vomiting or diarrhea.
Health authorities advise those who develop respiratory symptoms to seek prompt medical advice at their nearest health center or hospital rather than self-medicating. Special attention is recommended for individuals in prioritized groups.
Preventive actions recommended by health officials include frequent handwashing with soap and water; covering mouth and nose with the elbow when coughing or sneezing; ventilating rooms; avoiding sharing personal items; and cleaning frequently touched surfaces.
Annual flu vaccination remains a key prevention tool. It is recommended for children aged 6-24 months; pregnant women and those who have recently given birth; people aged 2-64 years with risk factors; people over 65 years old; healthcare workers; and other strategic personnel. The vaccines are described as safe and free of charge at vaccination centers throughout the province.
Jujuy continues epidemiological surveillance alongside other provinces to monitor respiratory virus trends and ensure an integrated healthcare response across its territory.
