Hand Foot and Mouth Disease

Hand, Foot, and Mouth Disease is a common illness that usually causes fever, mouth sores, and skin rash. It can spread quickly at schools and childcare centers. Most people get better on their own in 7 to 10 days. Though it mostly affects young children, it can occur at any age. Outbreaks are most common in the Summer and Fall. Despite its scary name, the illness is generally mild.

How it Spreads

Hand, Foot and Mouth Disease is caused by viruses. A person infected with one of the viruses can be contagious, meaning they can pass the virus easily to other people. It can be spread through contact with:
- Droplets with virus particles made after the infected person sneezes, coughs, or talks. These droplets can land on or be rubbed into the eyes, nose, or mouth.
- Contact with the droplets from objects contaminated by children who have the viruses.
- Fluid from blisters.
- Stool of children who are infected. This generally involves an infected child contaminating their own fingers and then touching an object that another child touches. The child who touched the contaminated object then puts their fingers into their own mouth or another person's mouth.

Signs and Symptoms

Tiny blisters in the mouth and on the fingers, palms of hands, buttocks, and soles of feet that last a little longer than a week (one, few, or all of these body sites may be involved with the blisters).
May see common cold signs or symptoms with fever, sore throat, runny nose, and cough.
Blisters in the mouth that can make it difficult for children to eat or drink.
Vomiting and diarrhea can occur, but are less frequent.
Most children have mild symptoms for 7 to 10 days.

Prevention

Wash hands often for at least 15 to 20 seconds:
- after changing diapers
- after using the toilet
- after handling items soiled with stool or saliva
- after blowing your nose, coughing, or sneezing
- before/after caring for someone who is sick
- before eating or making meals
Avoid touching your eyes, nose, and mouth.
Keep blisters clean and avoid touching them.
Teach and help children to wash their hands and avoid toughing the blisters.
Avoid sharing of toys between children who are likely to place toys in their mouth.
Avoid close contact with infected people (e.g., hugging, kissing).
Do not share eating and drinking utensils.
Clean and disinfect high-touch surfaces and shared items, such as toys and doorknobs, as well as change tables and pads after each diaper change.

Treatment

There is no specific medical treatment. Most people get better on their own in 7 to 10 days. Talk to your healthcare provider if you have concerns.

Reporting

Individual cases not reportable to the Health Unit.

Should one go to childcare, school, or work if they have hand, foot, and mouth disease?

No exclusion necessary, unless too ill to participate in activities, has uncontrolled drooling with mouth sores, or has a fever with behavioural change.

For schools and childcare centres, exclusion will not reduce spread because some children may shed the virus without being symptomatic and other children who became ill may shed the virus for weeks in their stool.

Follow the direction of your healthcare provider or occupational health at your workplace.
