Medical experts in Vietnam are issuing warnings regarding seasonal influenza risks as the transition from summer to autumn increases the likelihood of respiratory diseases. Data from the National Children’s Hospital indicated approximately 60-80 positive cases per week during late summer 2026, with a 20% hospitalization rate.

Health officials, including Dr. Truong Huu Khanh of the Ho Chi Minh City Infectious Disease Association, emphasize that influenza can lead to severe complications such as pneumonia, respiratory failure, myocarditis, encephalitis, and multi-organ failure. 

Specialists are urging high-risk groups—specifically pregnant women and children under five—to prioritize annual vaccinations. For pregnant women, vaccination is noted to provide dual protection by passing antibodies to the infant. For children, particularly those under two, vaccination is critical due to their developing immune systems. While a recent rise in COVID-19 cases has been noted, officials state current trends remain consistent with previous years.
