How Long Does Hand, Foot, and Mouth Disease Last?

Quick Answer

Hand, foot, and mouth disease (HFMD) typically runs its course in 7–10 days. Symptoms begin 3–6 days after exposure, with fever and sore throat first, followed by mouth ulcers and a rash on the hands and feet. Most people, especially children, recover fully without treatment.

HFMD Timeline

Phase	Timeframe	What Happens
Incubation	3–6 days after exposure	No symptoms yet; virus is developing
Early illness	Day 1–2	Fever, sore throat, reduced appetite
Blister stage	Day 2–5	Painful mouth sores, rash on hands and feet
Recovery	Day 5–10	Fever gone, sores heal, rash fades
Post-illness	Weeks 1–4	Possible skin peeling or nail changes

Symptoms and Their Duration

• Fever — Usually the first sign, lasting 2–4 days.
• Mouth sores — Painful ulcers on the tongue, gums, and cheeks that last about a week.
• Skin rash — Flat or raised red spots, sometimes with blisters, on the palms and soles, lasting up to 10 days.
• Peeling and nail changes — Skin on fingers or toes may peel, and nails can loosen or shed weeks later, then regrow normally.

How Long Is It Contagious?

People with HFMD are most contagious during the first week of illness, but the virus can spread even after symptoms fade. It can remain in stool for weeks after recovery. To reduce spread, children should stay home while they have a fever or open blisters.

Factors That Affect How Long It Lasts

• Age — Children usually recover faster; adults may have longer or more severe symptoms.
• Immune health — A weakened immune system can prolong illness.
• Which virus strain — Coxsackievirus A16 is most common; some strains cause more severe disease.
• Secondary infection — Scratched or infected blisters can slow healing.

How to Ease Symptoms and Speed Comfort

1. Manage pain and fever — Use acetaminophen or ibuprofen as directed (never aspirin for children).
2. Soothe the mouth — Offer cold liquids, ice pops, and soft foods; avoid acidic or spicy items.
3. Stay hydrated — Dehydration from painful swallowing is the main complication to watch for.
4. Keep skin clean — Don't pop blisters; wash hands often to prevent spread.
5. Rest — Recovery is faster with plenty of rest.

When to See a Doctor

Seek medical care if there are signs of dehydration (no wet diapers, no tears, dry mouth, unusual sleepiness), a fever lasting more than 3 days, a very high fever, or symptoms that worsen instead of improving after 10 days. Call promptly for a stiff neck, severe headache, or trouble breathing, and always contact a doctor for infants under 6 months or anyone with a weakened immune system.
