How to prevent hand-foot-mouth disease in kids: practical tips for 2025

Hand-foot-mouth disease gains attention in 2025 due to outbreaks in daycare centers and schools across Brazil, mainly affecting children under five. Caused by enteroviruses like Coxsackie A16, the viral infection peaks in autumn and winter, as warned by health departments in states like Amazonas and Mato Grosso do Sul. Parents and educators seek guidance to identify and curb its spread, which occurs through contact with secretions or contaminated objects.

Initial symptoms include fever above 38°C, sore throat, and loss of appetite, progressing to specific lesions within hours. Transmission happens quickly in group settings, explaining the rise in reported cases this year.

Health authorities recommend immediate isolation upon detecting symptoms, prioritizing hygiene to reduce risks.

Key characteristics of the infection

Hand-foot-mouth disease stems from enteroviruses affecting the digestive tract and spreading via respiratory or fecal routes. In 2025, records show an incubation period of three to six days, with higher incidence in infants and preschoolers. No vaccine is approved in Brazil, but clinical diagnosis aids early control.

Severe cases account for less than 1% of records, according to epidemiological surveillance, focusing on complications like dehydration from painful oral lesions.

Initial symptoms and progression

Fever appears first, lasting two to three days, followed by red spots in the mouth that turn into painful ulcers. Lesions on palms and soles emerge as small blisters, typically without intense itching.

Children may experience general malaise, with vomiting or diarrhea in 20% of cases, worsening the need for constant hydration.

The full course lasts five to seven days, with residual nail peeling in some cases, without permanent sequelae.

Identified transmission methods

The virus spreads through direct contact with saliva, feces, or lesion fluids, contaminating common surfaces in daycares. Asymptomatic adults contribute to spread, especially when handling toys without proper cleaning.

In schools, sharing utensils accelerates contagion, with peaks in humid regions like the North.

Indirect transmission via food or water is rare but underscores the need for daily kitchen cleaning.

Reports from 2025 note the virus persists in feces for up to four weeks post-symptoms, requiring prolonged care.

Daily hygiene measures

Washing hands with soap and water for at least 20 seconds prevents most infections, especially after diaper changes or before meals. Frequently touched surfaces, like tables and toys, should be disinfected weekly with diluted solution.

Avoiding blowing on hot food for children reduces direct oral transmission, a common family practice.

Caregivers should use gloves when handling lesions, disposing of materials in lidded bins to contain contaminated waste.

Strategies in school settings

Daycares enforce a mandatory seven-day isolation after the first symptom, monitoring entire classes for early detection. Educators receive annual training on classroom disinfection, focusing on floors and exposed furniture.

• Keep distance between children during group snacks;
• Schedule collective hygiene breaks after recreational activities;
• Record weekly cases to alert parents via digital notices.

These measures reduced outbreaks by 30% in Mato Grosso do Sul units this year.

Practical tips for families

Parents teach children not to touch eyes, nose, or mouth with dirty hands, a habit blocking viral entry in 70% of cases. Offering cold drinks during episodes eases oral discomfort, maintaining fluid intake above 1 liter daily for two-year-olds.

• Cover coughs with the forearm instead of hands;
• Dispose of used tissues immediately;
• Avoid crowded parks during seasonal peaks.

These simple routines integrate easily into daily life.

Care during home treatment

Relieving fever with paracetamol under medical guidance keeps temperatures controlled, while soft foods like purees aid nutrition without irritating ulcers. Lukewarm baths prevent additional inflammation in blisters, with gentle drying to avoid secondary infections.

Monitoring dehydration signs, like dry mouth or reduced urine, requires immediate consultation, though rare in mild cases.

Relative rest speeds recovery, with gradual return to activities after complete healing.

Surveillance in endemic regions

In the North and Midwest, health departments intensify campaigns in June 2025, distributing educational materials at health posts. National records show 15% more notifications than in 2024, linked to higher viral circulation post-rains.

Rural families access rapid tests via mobile units, aiding local outbreak mapping.

This integrated approach strengthens collective response, cutting hospitalizations by 25% in monitored areas.
