Vietnam HFMD Outbreak: EV71 Strain Fuels Fears

Vietnam has reported approximately 7,300 cases of hand, foot, and mouth disease (HFMD) across its most populous city since the beginning of the year. During the week of March 9 to 15, 2026, 837 new cases were recorded. Health authorities are particularly alarmed by the presence of the Enterovirus 71 (EV71) strain, which accounted for 25% of tested samples. This highly virulent strain poses a significant risk due to its rapid transmission and potential for severe neurological and respiratory complications in children under five.

To combat the escalating situation, health officials have initiated enhanced surveillance and preventive measures. Schools are being urged to ensure adequate handwashing facilities and coordinate with local health authorities to disseminate public health messaging. The health ministry has also put forward a proposal for mandatory medical isolation for nine infectious diseases, including HFMD. This measure would apply to confirmed cases, suspected cases, carriers, and exposed individuals, with isolation potentially occurring at home or in designated facilities.

Symptoms of HFMD typically include fever, sore throat, mouth sores, and a rash. While most children recover within seven to ten days, health experts warn that symptoms can worsen rapidly. The US Centres for Disease Control and Prevention (CDC) notes that adults can also contract the disease. Prevention strategies emphasize frequent handwashing, avoiding face touching with unwashed hands, and regular disinfection of frequently touched surfaces and shared items like toys.
