Hanoi (VNA) – Infectious respiratory transmitted diseases are making the rounds in the current winter-spring season, increasing the risk of illnesses such as seasonal flu, measles and roseola.
Vietnam has recorded just 912 flu cases nationwide so far this year, a staggering 97% drop compared to the same period last year, which saw 34,442 cases. Even more encouragingly, there were no fatalities reported during this time.
However, health experts cautioned against complacency. While the number of cases has plummeted, the virulence of detected flu strains, such as A/H1N1, A/H3N2, and influenza B, remains unchanged. These viruses are still capable of causing severe illness, particularly among vulnerable populations like children and those with underlying health conditions.
Major hospitals in Hanoi, including the National Hospital for Tropical Diseases, Bach Mai Hospital, and the National Children's Hospital, have observed a concerning rise in severe flu cases. Some patients infected with influenza A require advanced interventions such as Extracorporeal Membrane Oxygenation (ECMO), a life-support measure used when lungs fail to function properly. Others faced complications exacerbated by pre-existing health issues.
Experts attributed this increase to heightened travel and altered living conditions during the Lunar New Year (Tet) holiday, a time when families gather and crowds swell.
Also in 2024, Vietnam documented 289,214 seasonal flu cases, resulting in eight deaths, an 18% decrease in cases but a five-fatality increase compared to 2023. Notably, four deaths from influenza A(H1N1) occurred in Binh Dinh province, all involving patients with severe chronic illnesses. Fortunately, no new virus variants were detected. Several cities and provinces posted high numbers of flu cases, including Thanh Hoa (46,600), Thai Binh (26,345), Nghe An (17,949), Ha Tinh (14,073), and Son La (10,162).
Vietnam is not alone in grappling with these challenges. Globally, the incidence of influenza-like illnesses (ILI) and acute respiratory infections (ARI) has been climbing since late 2024, particularly in the northern hemisphere. Different regions are battling distinct flu strains. Europe reports all subtypes, North America sees predominantly influenza A, Central America and the Caribbean face A/H3N2, West Africa battles influenza B, and East Africa contends with similar outbreaks. Meanwhile, Asia is witnessing a resurgence of influenza A(H1N1) pdm09.
Experts stressed that seasonal flu is an acute respiratory infection caused by influenza viruses, occurring annually, typically peaking in winter and early spring.
The public was urged not to underestimate its impact, especially concerning children who are particularly vulnerable and often require longer recovery times.
To proactively prevent seasonal flu, the public should get vaccinated, cover mouth and nose when coughing or sneezing, and wear masks in crowded places and on public transportation. Other daily precautions include washing hands regularly with soap and clean water or use hand sanitizer, especially after coughing or sneezing, avoid spitting in public places, minimise contact with those showing signs of flu unless absolutely necessary.
They should also maintain a healthy lifestyle with nutritious foods, regular physical activity, and immune-boosting practices.
If experiencing symptoms like cough, fever, runny nose, headache or fatigue, seeking medical advice promptly is crucial. Self-diagnosis and self-medication should be avoided to ensure proper examination and treatment./.
