Building on international alerts, Colombia's Ministry of Health confirmed the first case of influenza A(H3N2) subclade K in a traveler with mild symptoms. Officials are monitoring this seasonal variant, with pediatric experts urging enhanced prevention amid peak transmission risks for children.
Colombia's Ministry of Health and Social Protection announced the first confirmed case of influenza A(H3N2) subclade K, detected via molecular tests by the National Institute of Health (INS). The patient presented mild respiratory symptoms and recent international travel history, consistent with patterns seen in global spread reported earlier in Europe, the US, and Latin American surveillance.
Authorities are tracking influenza A subtypes like A(H1N1)pdm09 and A(H3N2), which peak seasonally between May-June and September-November. This detection follows broader alerts on the K subclade's circulation abroad.
Dr. Catalina Vásquez, Pediatric Pulmonology coordinator at Hospital Infantil Universitario de San José in Cali, highlights risks for children under three and those with chronic conditions like asthma or diabetes. 'Infections can progress to severe pneumonia, especially in young children,' she warns, advising prompt care for symptoms such as breathing difficulty, persistent fever, or lethargy.
Recommendations include annual vaccination for children under three, seniors over 60, pregnant women, chronically ill individuals, and healthcare workers, alongside handwashing, ventilation, and breastfeeding. 'Timely prevention is key during peak seasons,' Dr. Vásquez emphasizes.
This case reinforces the need for vigilance to curb complications in vulnerable groups.
