The Ministry of Health and Social Protection, in coordination with the National Institute of Health (INS), informs the public that, as anticipated in the communication of December 18, the detection of the influenza A(H3N2) virus, subclade K (J.2.4.1), was confirmed in Colombia, in an imported case with a history of international travel to the United States.
The case involves an individual who presented with mild respiratory symptoms, such as fever, runny nose, and cough, and who reported recent travel on a cruise departing from Miami. Initial identification was made by the Genomics Group of Antioquia and subsequently confirmed by the Virology Group of the Directorate of Public Health Networks and the Genomics of Emerging Microorganisms Group of the Directorate of Public Health Research at the National Institute of Health (INS) through whole-genome sequencing (NGS).
To date, there has been no increase in the incidence of acute respiratory infections, nor in the severity of cases, hospitalizations, or deaths associated with this subclade of the virus in the country. Based on available evidence, the influenza vaccine continues to be effective in preventing serious complications, hospitalizations, and deaths.

The country has a strengthened epidemiological and laboratory surveillance system, which allows for the early detection of respiratory viruses and the timely implementation of control measures. The Ministry of Health and Social Protection will continue to transparently report any updates relevant to the country’s public health.
