How Soon Can You Get HFMD Again

Hand, Foot, and Mouth Disease (HFMD) is a common yet often misunderstood illness, particularly among children.

What Causes HFMD and How It Spreads

HFMD is a contagious illness caused by coxsackieviruses.

HFMD is particularly common in settings like schools or nurseries, where close interaction between children increases the risk of transmission:

• Coughing and sneezing
• Touching contaminated objects
• Contact with an infected person via saliva, nasal secretions, blister fluid or faeces

Duration and Recovery Timeline

The duration of HFMD varies depending on the individual and the severity of the symptoms. Generally, the illness lasts 7–10 days.

Fever and sore throat usually appear first, followed by a blistering rash in a few days. Symptoms often peak by day three or four and then gradually ease.

Signs of recovery include reduced fever, improved appetite, and more energy. Blisters may take longer to heal, even after children are no longer contagious.

Can You Get HFMD Again?

Yes, it is possible to get HFMD more than once.

Immunity to HFMD is virus-specific, which means that recovering from one strain of the virus (e.g., coxsackievirus A16) only protects against that particular strain.

With multiple strains in circulation, reinfection is possible. Children with developing immune systems are especially vulnerable to catching it again.

Adults, on the other hand, tend to build stronger immunity, though reinfection is not entirely out of the question.

HFMD Lookalikes: What Can Be Mistaken for It

HFMD shares symptoms with other illnesses, which can sometimes cause confusion.

Conditions like chickenpox, herpangina, and other viral rashes can appear similar but have distinct differences. Here’s how HFMD differs from other conditions:

• Chickenpox: Causes blisters across the entire body, whereas HFMD blisters are mainly found on the hands, feet, and mouth. 
• Herpangina: Leads to mouth sores but doesn’t include rashes on the hands and feet, unlike HFMD. 
• Other conditions: Allergic reactions or viral rashes could also be mistaken for HFMD. 

If you’re unsure, consulting a healthcare professional is the best way to get an accurate diagnosis.

Diet Tips: What to Eat with HFMD

Eating can become a challenge for those suffering from HFMD due to painful sores in the mouth. Soft, cool foods are often the most soothing. Here are some safe options:

• Cold treats like yoghurt, popsicles, or ice cream can help numb mouth pain.
• Hydrating foods such as watermelon or cucumber help maintain hydration levels.
• Soft meals like mashed potatoes, soups, or porridge are easy to swallow and can provide necessary nutrients.

It’s wise to avoid spicy, salty, or acidic items, as these can irritate the sores further. Encourage regular sips of water or cool liquids to prevent dehydration.

Prevention Tips for Families and Schools

Preventing HFMD relies on good hygiene and early detection. Both families and community settings play a crucial role in minimising the spread of the disease.

Tips for Families

• Teach children to wash their hands thoroughly and frequently, especially before meals and after using the toilet. 
• Encourage children to cover their mouths when coughing or sneezing. 
• Regularly disinfect toys and common surfaces in the home to reduce contamination. 

Tips for Schools and Nurseries

• Maintain proper sanitation practices in shared spaces. 
• Encourage parents to keep children at home who show symptoms of HFMD. 
• Quickly isolate confirmed cases to minimise outbreaks in group settings. 

Stay Vigilant, Stay Healthy

Combating HFMD calls for a two-pronged approach – treating symptoms effectively and preventing the virus’s spread.

Reinfection is always a possibility, but proactive hygiene and care can reduce its likelihood.

By staying alert, encouraging healthy habits, and raising awareness, parents and caregivers can better protect children from this illness.
