In Plain English: The Clinical Takeaway
- Enterovirus 71 (EV71): A specific strain of the virus known to cause severe complications, and mortality in young children.
- Fecal-Oral Transmission: The primary mechanism of viral spread, occurring through contact with contaminated surfaces, hands, or direct contact like handshakes, embraces, or kissing.
- Active Immunization: A vaccine is available for children aged six months to five years, administered in a two-dose series separated by at least one month.
Epidemiological Surge and Regional Spread Across Vietnam
According to disease surveillance data released by the Ho Chi Minh City Center for Disease Control (HCDC) on October 28, local infections escalated sharply beginning in early September. Weekly caseloads surpassed 1,400 during the 37th week of the year and remained above the five-year average for four straight reporting periods. Nationally, Vietnam registered approximately 100,000 hand, foot, and mouth disease cases between January and September 2026, representing a more than 2.5-fold increase compared to the previous year. Epidemiological data indicates that children under the age of five account for 87.3% of all documented infections nationwide. Beyond Ho Chi Minh City, the highest case concentrations over the recent four-week window appear in Dong Nai, Dong Thap, Tay Ninh, Lam Dong, Da Nang, and Hanoi, with health authorities warning that transmission will likely continue.

Transmission Dynamics and Institutional Prevention Protocols
Hand, foot, and mouth disease spreads primarily through the fecal-oral route, direct contact via handshakes, embraces, or kissing, and contact with contaminated environmental surfaces such as toys, clothing, and doorknobs. HCDC emphasizes the ‘Three Cleanliness’ preventive framework: consuming cooked food and boiled water with unshared utensils; regularly cleaning toys, doorknobs, desks, and floors with soap or detergent; and practicing rigorous hand hygiene before meals and after bowel movements. Educational institutions are directed to maintain environmental sanitation, ensure adequate ventilation, conduct morning health screenings, and supply clean water and soap.
Contraindications & When to Consult a Doctor
Pediatric patients exhibiting these clinical signs must be isolated at home and evaluated by healthcare professionals. Per public health guidelines, infected children must suspend school attendance for a minimum of 10 days or until all symptoms completely resolve, while avoiding public gatherings during the acute 7-to-10-day window. Blister fluids must be handled and disposed of with strict sanitary precautions. Parents seeking active immunization should consult authorized vaccination centers regarding the two-dose EV71 vaccine schedule for children aged six months to five years.
