Health authorities are issuing urgent warnings following a significant surge in Hand, Foot, and Mouth Disease (HFMD), with nearly 26,000 cases and eight deaths reported since the beginning of the year. The spike is driven largely by the prevalence of the EV71 viral strain, a variant known to be associated with more severe neurological complications and higher risks of critical illness in young children.
The escalation in infections has been particularly pronounced during March, with official data showing a clear upward trend in weekly averages compared to previous years. Public health officials attribute this rise to a combination of early onset of hot and humid weather—conditions under which enteroviruses thrive—and the high transmissibility of the current strain within childcare settings.
According to Vo Hai Son, Deputy Director of the Department of Disease Prevention, the burden of the disease is concentrated among children under the age of five. This demographic, particularly those in preschools and kindergartens, remains the most vulnerable to both the initial infection and the potential progression to severe disease if not managed early.
The Risks Associated with the EV71 Strain
While HFMD is often viewed as a mild childhood illness, the presence of World Health Organization recognized enteroviruses like EV71 changes the clinical outlook. Unlike milder strains, EV71 can lead to severe complications, including viral meningitis or encephalitis, which can affect the central nervous system and lead to fatalities if medical intervention is delayed.
The current outbreak highlights a seasonal pattern that typically peaks between March and May, and again from September to October. Because the virus is primarily transmitted via the gastrointestinal route—often through contaminated surfaces, toys, or direct contact with nasal and throat secretions—the environment of a crowded classroom provides an ideal vector for rapid spread.
Health officials warn that without the immediate implementation of comprehensive prevention and control measures, the number of severe cases could continue to climb throughout the current peak season.
Identifying Symptoms and Early Warning Signs
For parents and caregivers, early detection is the most effective tool in preventing the progression of the disease. The transition from a mild fever to a critical state can happen quickly, making vigilant monitoring essential for children under five.
The primary symptoms to watch for include:
- Fever: A sudden onset of high temperature is often the first sign of infection.
- Oral Ulcers: Painful sores or blisters appearing in the mouth and throat, which may produce eating or drinking difficult.
- Skin Rash: Compact red spots or blisters appearing specifically on the palms of the hands and the soles of the feet.
- General Malaise: Irritability, loss of appetite, and lethargy in toddlers.
Vo Hai Son emphasized a critical directive for families: “Parents must monitor their children’s health regularly, especially those under five. When suspicious signs such as fever, mouth ulcers, or rashes on the hands or feet appear, they must take them to a medical center for examination.”
Preventative Strategies for Schools and Homes
To curb the transmission rate, the health sector is integrating multiple detection channels in collaboration with local authorities and the education sector. The strategy focuses on breaking the chain of infection at the source: the classroom.
Current guidelines for educational facilities and parents include:
- Strict Isolation: Children showing any symptoms must remain at home and be excluded from school until fully recovered to prevent the virus from spreading to classmates.
- Environmental Hygiene: Frequent disinfection of classroom surfaces, shared toys, and common areas.
- Personal Hygiene: Encouraging rigorous hand-washing with soap and water, particularly after using the restroom and before meals.
- Enhanced Communication: Establishing direct lines of communication between teachers and parents to report new cases immediately.
| Factor | Details |
|---|---|
| High-Risk Age Group | Children under 5 years old |
| Primary Viral Strain | EV71 (Associated with severe illness) |
| Peak Periods | March–May and September–October |
| Transmission Route | Gastrointestinal / Direct Contact |
Clinical Management and Public Health Outlook
From a medical perspective, there is no specific antiviral treatment for HFMD; management is primarily supportive, focusing on hydration and fever reduction. Although, the risk of the EV71 strain necessitates a lower threshold for hospitalization. Medical professionals are urged to monitor for “red flag” symptoms, such as persistent vomiting, muscle weakness, or difficulty breathing, which may indicate neurological involvement.
The integration of the education sector into the public health response is intended to create a “surveillance net” that can identify outbreaks in real-time. By training teachers to recognize the early signs of the rash and fever, health officials hope to reduce the time between the onset of symptoms and clinical diagnosis.

Health authorities will continue to monitor the weekly infection rates and provide updates as the current peak season progresses. The next phase of the response will likely involve a review of the effectiveness of classroom disinfection protocols and a reassessment of case numbers as the region moves toward the end of the spring peak.
