Hand, Foot, and Mouth Disease (HFMD) is a common viral illness that mostly affects infants and young children, though adults can also catch it. In Singapore, HFMD is a significant concern, especially in childcare settings. This article will help parents understand HFMD, including its symptoms, preventive measures, and treatments.
What is Hand, Foot, and Mouth Disease?
HFMD is a very contagious viral infection caused by a group of enteroviruses such as the coxsackievirus, enterovirus, and echovirus. It commonly affects children below 5 years old, although adults can also be infected. As the name suggests, it typically causes rashes on the hands and feet, and ulcers in the mouth.
How Does HFMD Spread?
HFMD can be transmitted through saliva, mucus, fluid from the blisters, and faeces of the infected person. It spreads via direct physical contact such as hugging, kissing, sharing food and drinks, or through contaminated objects. The incubation period is about 3 to 5 days.
Dr. Jacquelyn Melody, Senior Family Physician at Oaklife Family Clinic, explains, "HFMD is often called the 'silent sufferer' for kids because the rashes and ulcers can cause significant discomfort without any prior warning."
How Common is HFMD in Singapore?
HFMD is quite common in Singapore, especially among children under five. According to the Ministry of Health (MOH), there were over 40,000 reported cases in 2019. The disease often peaks during the hotter months, with frequent outbreaks in kindergartens and childcare centers.
What are the Symptoms of HFMD?
HFMD symptoms usually appear 3 to 5 days after exposure to the virus.
Common symptoms include:
Rashes: Usually found on the hands, feet, particularly the palms and soles, around the mouth, buttocks, elbows, and knees. They can be flat, rounded, or fluid-filled. The rashes on the palms and soles may be painful.
Ulcers: Can be found anywhere in the mouth including the tongue and back of the throat. Children usually complain of throat or mouth pain which often leads to poor oral intake and crankiness . Babies and toddlers with HFMD tend to drool more than usual.
Fever: May be the first symptom that appears. It is not uncommon to reach a temperature of 40 degrees celcius.
Vomiting and diarrhoea
Lethargy
However the symptoms varies; some may only get 1 or 2 of the symptoms, while others get more. Each symptom also may appears at different stages of the illness.
Dr. Jacquelyn Melody adds, "HFMD can cause significant discomfort in children, making it crucial for parents to recognize the symptoms early and provide appropriate care."
What are the Complications of HFMD?
The most common complication of HFMD is dehydration due to poor fluid intake. Certain strains of the virus, such as EV71, can cause serious complications to the heart, brain, and nervous system, but this is rare.
Worrying Symptoms
Parents should be concerned if their child exhibits:
Poor feeding
Lethargy
Shortness of breath
Drowsiness
Confusion
Severe headache
Persistent vomiting
Fits
If you notice any of these symptoms during the course of the illness, consult a doctor immediately.
How Long Will It Take for My Child to Recover from HFMD?
Recovery typically takes about 7 to 10 days. However, the virus is still shed in the faeces for about 12 weeks, meaning the faeces remain contagious for a while.
Can My Child Get Infected Again?
Yes, children can get infected again because there are different strains of enteroviruses which cause HFMD and Herpangina. Immunity to one strain may not protect against others.
What is the Treatment for HFMD?
The mainstay of treatment is symptomatic relief.
Paracetamol and Ibuprofen are commonly used to manage fever and painful ulcers.
Sometimes topical gels can be applied to the ulcers or pacifiers.
At home, parents should provide a soft diet and plenty of fluids. Focus on fluid intake rather than solid intake to prevent dehydration. Offer cold fluids and popsicles to relieve painful ulcers and encourage fluid consumption.
There is no special cream for the rashes.
Dr. Jacquelyn Melody advises, "Cool the food or drinks, including formula milk, before giving them to the child. Warm or hot foods can be more painful to the ulcers. Cold fluids and popsicles can help soothe the painful ulcers and encourage more fluid intake."
What Should Parents Do to Prevent HFMD?
Preventing HFMD involves good hygiene and awareness. Here are some tips for parents:
Frequent Hand Washing
Teach your children to wash their hands regularly with soap and water, especially after using the toilet and before eating.
Disinfecting Surfaces
Regularly clean and disinfect common surfaces like toys, doorknobs, and furniture.
Avoiding Close Contact
If your child is infected, keep him/her at home to prevent spreading the virus. Do not send him/her to school or daycare for the whole duration of the Medical Certificate (MC) or until he/she is certified fit to return to school by their doctor.
Promoting Vaccination
While there is no specific vaccine for HFMD, ensuring your child is up-to-date on other vaccinations helps maintain overall health.
HFMD in Adults
Adults can also get HFMD, especially if they are in close contact with infected children. Adults usually have milder symptoms, but it is still important to practice good hygiene.
"Preventing HFMD starts with good hygiene practices. By educating parents and children about proper hand washing and disinfecting surfaces, we can reduce the spread of this contagious disease." says Dr. Jacquelyn Melody
One of our patients, Mrs. Tan, shared her experience: "When my toddler, Emily, first showed symptoms of HFMD, I was really worried. But with the guidance from Dr. Jacquelyn at Oaklife Family Clinic, we managed to keep Emily hydrated and comfortable. The cold popsicles were a lifesaver!"
