Hand, Foot and Mouth Disease in Peak Season: Early Recognition for the Right Protection of Your Child

From April to June each year, Hand, Foot and Mouth Disease (HFMD) enters its peak season. Alongside the common viral strains, the circulation of the Enterovirus 71 (EV71) variant remains a major concern for paediatricians due to its rapid spread and the risk of silent progression to severe complications.

At FV Hospital, we encourage parents to actively monitor their children’s symptoms so that appropriate action can be taken promptly, without unnecessary panic, but also without underestimating the disease.

Be Alert to the “Silent Signs” of EV71

Unlike milder strains that often cause numerous blisters, children infected with EV71 may sometimes show very subtle symptoms:

• Small mouth ulcers, easily mistaken for common mouth sores, causing poor appetite and irritability.
• Very few blisters, appearing only in hard-to-notice areas such as the buttocks, elbows, or behind the knees.

3 “Red Flag” Signs Requiring Immediate Medical Attention

Parents should bring their child to the nearest medical facility immediately if any of the following symptoms appear:

1. Persistent high fever: A temperature above 39°C lasting more than 2 days and difficult to reduce with standard fever medication.
2. Startling or jerking movements: This may indicate that viral toxins are affecting the nervous system. Pay particular attention if the child startles while falling asleep or during play.
3. Movement disorders: Unsteady walking, trembling hands or legs, or weaker grip strength than usual.

Prevention Remains Essential While No Vaccine Is Available

As there is currently no specific vaccine available, maintaining good hygiene habits remains the most important protective shield:

• Hand hygiene: Wash hands frequently with soap for both children and caregivers.
• Surface disinfection: Clean toys, school supplies, and shared living areas thoroughly.
• Safe isolation: Keep children at home for at least 10 days from the onset of symptoms to support recovery and prevent community transmission.
