## Q&A

**Q: What is HFMD (Penyakit Tangan, Kaki dan Mulut) and what causes it?**  
A: HFMD is a common viral infection caused by enteroviruses, most frequently Coxsackievirus A16 and Enterovirus 71 (EV-A71). It primarily affects infants and children under age five, presenting with fever, sore throat, painful oral sores, and maculopapular or vesicular rashes on the palms, soles, and diaper areas.

**Q: How does HFMD spread among children in daycare or school?**  
A: HFMD spreads through direct contact with nose and throat secretions (saliva, sputum, nasal mucus), fluid from blisters, respiratory droplets from coughing or sneezing, and the fecal-oral route via contaminated hands, toys, or surfaces.

**Q: What is the recommended home care treatment for a child with HFMD?**  
A: Because HFMD is viral, antibiotics are ineffective. Care focuses on symptom relief: offering cold fluids, popsicles, and soft non-acidic foods to soothe mouth ulcers, administering pediatrician-approved antipyretics for fever, and maintaining strict handwashing to prevent household spread.

**Q: What severe warning signs require emergency medical attention?**  
A: Immediate hospitalization is required if a child displays persistent high fever lasting over 48 hours, extreme drowsiness, repeated vomiting, sudden jerking movements (myoclonic jerks), rapid heart rate, or inability to swallow fluids resulting in dehydration.

**Q: When is it safe for a child to return to school after an HFMD infection?**  
A: Children should remain isolated until all blisters have completely dried and crusted over, mouth ulcers have healed, and they have been fever-free for at least 24 hours without medication—typically around 7 to 10 days from symptom onset.
