Following a recent surge that claimed 13 lives as November 2025, health officials are reporting a decline in influenza cases across the region. While the A(H3N2) virus drove a important wave of illness – with nearly 200 hospitalizations reported over the past three months – a separate health concern is emerging. Authorities are now tracking an increase in acute gastroenteritis, commonly known as stomach flu, alongside a continued risk of leptospirosis, particularly in areas impacted by recent rainfall.
Flu Cases Decline After 13 Deaths, While Gastrointestinal Illnesses Rise
Health officials are reporting a decrease in influenza cases following a recent surge that resulted in 13 deaths since the start of the outbreak in November 2025. During the week of January 19-25, 2026 (Week 4), seven confirmed cases of influenza A were identified, leading to one hospitalization and one additional fatality. This brings the total number of flu-related deaths to thirteen.
Over the past three months, a total of 455 confirmed flu cases have been recorded, with 199 requiring hospitalization and 23 needing intensive care. The decline in key indicators suggests the peak of the epidemic, which was primarily driven by the A(H3N2) virus, has passed. This is welcome news as influenza can pose a serious health risk, particularly for vulnerable populations.
However, health authorities are observing a different trend with acute gastroenteritis (GEA). Reports indicate an increase in consultations for diarrhea and vomiting among both children and adults. Laboratory tests have identified norovirus and rotavirus as circulating pathogens, both of which are highly contagious, especially during warmer months.
Gastroenteritis Cases Increasing
The rise in gastrointestinal illnesses highlights the importance of preventative measures, as these infections can quickly spread within communities.
Staying Vigilant Against Multiple Illnesses
Even as influenza cases subside, public health officials continue to emphasize the importance of preventative measures such as frequent handwashing, proper food hygiene, and annual influenza vaccination to prevent severe illness and limit the spread of viruses. These practices remain crucial for protecting individual and community health.
Additionally, officials are warning of an increased risk of leptospirosis during the rainy season. Four cases were reported during the week of January 19-25, all requiring hospitalization, with two patients needing intensive care. This underscores the need for awareness and preventative measures in areas prone to flooding and water contamination.
The combination of these circulating illnesses serves as a reminder of the ongoing need for vigilance and proactive health practices.
