When to Seek Medical HelpSigns of dehydration (no wet nappies for 8+ hours, no tears when crying), high fever not responding to medication, extreme drowsiness or irritability, or symptoms lasting more than 10 days.
Fingernail PeelingA few weeks after hand, foot and mouth disease, some children experience fingernail and toenail peeling or loss. This is harmless and the nails grow back normally over 1–2 months.
Can adults get hand, foot and mouth disease?
Yes, though it's much more common in children under 5. Adult cases are usually milder but can occasionally be more uncomfortable.
Is it the same as foot and mouth disease in animals?
No — completely different diseases caused by different viruses. Hand, foot and mouth disease only affects humans.
Can my child go to nursery?
Most guidance says children can return once they feel well enough, even if spots remain, as the virus can shed for weeks after symptoms resolve.
