Hong Kong Faces Rising Hand, Foot and Mouth Disease Cases: What Parents Need to Know
Hong Kong health officials are urging heightened vigilance as cases of hand, foot and mouth disease (HFMD) surge among children, particularly in childcare facilities and schools. The recent increase prompts a renewed focus on preventative measures and rapid outbreak reporting.
The Centre for Health Protection (CHP) has observed a consistent climb in HFMD clusters over the past several weeks. Initial reports from October 26th to November 1st identified 17 outbreaks affecting 50 individuals. This number escalated to 20 outbreaks (53 people) and subsequently to 25 outbreaks (61 people) in the following fortnights. The most recent data, spanning November 16th to 20th, revealed an additional 16 outbreaks impacting 40 people. A significant 82% of the 78 outbreaks recorded between October 26th and November 20th originated within childcare centers, kindergartens, and primary schools.
Consultation rates for HFMD at childcare centers, kindergartens, private clinics, and public hospital emergency departments have remained elevated since late October, indicating widespread community transmission. While the majority of cases are mild, health authorities are closely monitoring the situation.
Understanding Hand, Foot and Mouth Disease
Hand, foot and mouth disease is a common viral illness, primarily affecting young children. Symptoms typically begin with a mild fever, reduced appetite, a general feeling of being unwell, and a sore throat. These initial symptoms are often followed by the characteristic appearance of painful mouth sores, which can develop into ulcers. A rash typically appears on the hands and feet, but can also occur on the buttocks and genitals.
According to Dr. Edwin Tsui, Controller of the CHP, HFMD is most frequently caused by enteroviruses, including Coxsackie virus and enterovirus 71 (EV71). The disease exhibits a seasonal pattern in Hong Kong, with peak periods occurring from May to July and again from October to December. Dr. Tsui emphasized the importance of parental awareness and close monitoring of children, given the current elevated activity levels.
Although most HFMD cases resolve within seven to ten days, severe complications, while rare, can occur. This year, three pediatric cases required hospitalization due to severe enterovirus infections, though all patients have since made a full recovery. The close proximity of young children in school and institutional settings significantly increases the risk of outbreaks.
Schools and institutions are reminded to strictly adhere to the CHP’s Guidelines on Prevention of Communicable Diseases and to promptly report any suspected outbreaks. Venues offering play facilities for children under six are also advised to implement the CHP’s recommended infection control protocols.
A common misconception exists regarding the effectiveness of alcohol-based sanitizers against HFMD viruses. Dr. Tsui clarified that alcohol is not reliably effective against certain viruses responsible for HFMD, including EV71. Therefore, thorough handwashing with liquid soap and water remains the most effective preventative measure.
What steps can communities take to proactively reduce the spread of HFMD beyond school and daycare settings? And how can parents balance protecting their children with maintaining their social and developmental needs?
Preventative Measures Against HFMD
The CHP recommends the following measures to prevent the spread of HFMD:
- Maintain good ventilation in indoor spaces.
- Practice frequent and thorough handwashing with liquid soap and water, especially before meals, after using the toilet, after contact with respiratory secretions, and after handling diapers or soiled materials.
- Cover the nose and mouth when coughing or sneezing, and dispose of used tissues properly.
- Regularly clean and disinfect frequently touched surfaces, including furniture, toys, and shared items, using a 1:99 diluted household bleach solution (one part bleach with 99 parts water). Allow the solution to sit for 15-30 minutes before rinsing and drying.
- For visible contamination (e.g., respiratory secretions, vomit, excreta), wipe the area with disposable absorbent towels, then disinfect with a 1:49 diluted bleach solution (one part bleach with 49 parts water). Allow the solution to sit for 15-30 minutes before rinsing and drying.
- Avoid crowded places whenever possible.
- Keep children with symptoms of HFMD at home until their fever subsides, rashes have healed, and all blisters have dried and crusted over.
