Flu Epidemic Declines After 13 Deaths – Gastroenteritis Rising

February 2, 2026 discoverhiddenusacom Health

Public health officials are observing a shifting landscape of infectious diseases. While the recent surge in influenza appears to be waning, other illnesses, notably gastro-enteritis, are on the rise. This comes as cases of leptospirosis, a bacterial infection spread through water, are also being reported.

Flu Epidemic Declining

Data from the fourth week of January 2026 (January 19-25) indicates a decrease in influenza activity. Seven confirmed cases of influenza A were reported during that week, resulting in one hospitalization and one death. This brings the total number of influenza-related deaths since the start of the epidemic in November 2025 to thirteen.

Over the three-month period, a total of 455 confirmed cases have been recorded, leading to 199 hospitalizations and 23 admissions to intensive care units. Health authorities have noted a consistent decline in key indicators, suggesting the end of the epidemic, which was primarily driven by the A(H3N2) virus.

Did You Know? The current influenza epidemic has resulted in 23 patients requiring intensive care since November 2025.

Gastroenteritis Cases Increasing

Conversely, acute gastroenteritis (GEA) cases are increasing. The sentinel network is reporting a rise in consultations for diarrhea and vomiting among both children and adults. Laboratory reports confirm the presence of norovirus and rotavirus, both highly contagious viruses, particularly during warmer seasons.

Staying Vigilant Against Infection

Even as influenza cases decline, public health officials emphasize the continued importance of preventative measures. These include frequent handwashing, proper food hygiene, and influenza vaccination to prevent severe illness and limit virus transmission.

The risk of leptospirosis also increases during the rainy season. During the fourth week of January, four cases were reported, all requiring hospitalization, with two patients needing intensive care.

Expert Insight: The concurrent decline in influenza and rise in gastro-enteritis highlights the dynamic nature of infectious disease patterns. Continued vigilance and adherence to preventative measures are crucial, as seasonal shifts can quickly alter the prevalence of different illnesses.
