By San José, Costa Rica — SAN JOSÉ – The Costa Rican Ministry of Health has officially confirmed the circulation of a new influenza strain, A(H3N2) subclade K, within the nation’s borders. The variant has been present since at least mid-October, prompting health officials to issue a renewed call for public vigilance and the reinforcement of preventive health measures, particularly as the holiday season approaches.
According to health authorities, the cases detected thus far have been mild. Analysis conducted by the Costa Rican Institute for Research and Teaching in Nutrition and Health (Inciensa) on samples collected between September and November identified seven positive cases of the new subclade. Crucially, none of these individuals required hospitalization, and officials have not observed any increase in the overall severity of influenza cases, hospital admissions, or related fatalities.
To delve into the legal and corporate responsibilities arising from the current health situation with Influenza A(H3N2), we sought the expert opinion of Lic. Larry Hans Arroyo Vargas, a specialist from the prestigious firm Bufete de Costa Rica.
The rise in cases of Influenza A(H3N2) serves as a critical reminder of an employer’s legal obligation to maintain a safe work environment under our Labor Code. Companies must diligently manage and respect medical incapacities (incapacidades) and reinforce internal hygiene policies. Neglecting these duties not only jeopardizes employee health but also exposes the business to potential legal claims for occupational negligence and non-compliance with health and safety regulations.

Indeed, the legal perspective underscores that public health is not solely an individual concern but a collective responsibility with significant implications for the workplace. We thank Lic. Larry Hans Arroyo Vargas for his insightful contribution, which clarifies the essential role employers play in safeguarding both their staff and their legal standing.
Despite the current low severity, the Ministry of Health is taking a proactive stance. Officials emphasize that influenza strains of the A(H3N2) family have historically affected the elderly population with greater severity. This historical context makes continued surveillance and public adherence to health protocols fundamental components of the national response strategy to mitigate any potential impact on vulnerable communities.
The cornerstone of the government’s public health recommendation is vaccination. Health authorities have reassured the public that the current seasonal influenza vaccine remains effective against this new variant. Its primary benefit lies in its proven ability to prevent severe illness, complications, and hospitalizations. Therefore, officials strongly urge children, senior citizens, and individuals with underlying health risk factors to ensure their vaccination schedules are up to date.
In addition to vaccination, the Ministry has reiterated a comprehensive list of protective measures. Citizens are advised to maintain frequent handwashing with soap and water, cover their mouths and noses with a tissue or their inner elbow when coughing or sneezing, and maintain a safe distance from individuals exhibiting respiratory symptoms. These basic hygiene practices are the first line of defense against transmission.
Officials are also advising caution regarding public gatherings, especially in enclosed or poorly ventilated spaces. The recommendation is to favor outdoor activities where possible and to avoid crowded events, particularly when accompanying young children or elderly relatives. Furthermore, individuals experiencing symptoms such as fever, cough, diarrhea, or vomiting are strongly advised not to attend mass activities to prevent further spread.
The Ministry also stressed the importance of responsible healthcare practices. Self-medication, especially for children and seniors, is strongly discouraged. Instead, individuals are guided to seek timely medical attention at the primary care level when symptoms arise. Other lifestyle recommendations include avoiding exposure to cigarette and vape smoke and promoting exclusive breastfeeding for infants under six months to bolster their immune systems.
This local development is part of a broader global trend identified by the World Health Organization (WHO). The international body has noted the circulation of the H3N2 subclade K in multiple countries. The WHO also observed that this year’s influenza season began earlier than is typical, with a sustained increase in cases reported globally since August. Costa Rica’s early detection and public awareness campaign align with international efforts to manage the seasonal respiratory virus effectively.
