This article provides an update on the influenza A H3N2 variant K situation in Bolivia as of December 22, 2023, and will be updated as new information becomes available. As of January 1, 2026, the situation remains as described below, with ongoing monitoring by Bolivian health authorities.
Current Situation: New Cases and National Alert
Bolivia has confirmed four cases of the influenza A H3N2 variant K, according to a statement by Bolivian Minister of Health and Sports, Marcela Flores, on December 22, 2023. The latest cases involve two children under five years of age, one in the Santa Cruz department and another in the Chuquisaca department. These cases were confirmed through genomic sequencing laboratory tests.
Previously, the first two cases of the K variant were detected in El Alto and La Paz. Simultaneously, Bolivia has recorded a total of 76 cases of influenza A H3N2 that are *not* related to the K variant, as of the official report date.
In response to the increasing number of cases, the Bolivian Government declared a national epidemiological alert on December 17, 2023, for both influenza A H3N2 and its variant K.This alert is a preventative measure designed to protect the country’s health system and prevent hospital overcrowding.
Patient Status and Treatment
Minister Flores reported that all four patients diagnosed with the K variant are currently stable and receiving medical treatment at home under health monitoring. This indicates a focus on managing the illness in a non-hospital setting where possible.
Government Response and Preparedness
The national epidemiological alert aims to enhance the vigilance of health personnel in identifying suspected cases, notably among vulnerable populations: children, the elderly, and individuals with pre-existing health conditions. This targeted approach is crucial for early detection and intervention.
The alert also facilitates expedited administrative processes for the procurement and distribution of essential medicines and medical supplies. minister Flores emphasized that these actions are “based on scientific evidence to prevent needless hospitalizations and protect the capacity of our health services.”
Variant K: Contagion and Severity
Minister Flores clarified that the K variant does not appear to be more lethal than other strains of influenza. However, she noted that the variant exhibits changes in three proteins that may increase its transmissibility from person to person. Clinical symptoms remain consistent with those of seasonal influenza.
Understanding the increased transmissibility is key to public health messaging and preventative measures. While the illness itself isn’t necessarily more severe, faster spread can still strain healthcare resources.
Public Health Recommendations
The Ministry of Health continues to urge the public to adhere to biosafety measures and promptly seek medical attention if experiencing respiratory symptoms. Early detection and appropriate medical care are vital for effective management of influenza cases.
