Summary
As the new school term begins, pediatric specialist Dr. Cheung Kit (張傑醫生) is urging parents to take precautions against infectious disease outbreaks in Hong Kong's kindergartens and schools. According to data from the Centre for Health Protection, hand-foot-and-mouth disease activity typically rises during early summer and after school reopenings. With the summer vacation reducing contact among children, cases remained stable during the break, but infections are expected to climb sharply now that students are back in classrooms .
Key Points
- Hand-foot-and-mouth disease, caused by Coxsackie virus and Enterovirus 71, has an incubation period of 3-6 days and spreads through droplets, saliva, blister fluid, and feces .
- Influenza A (H3) activity remains at high levels in Hong Kong, with more cases reported this year compared to last year, leading to increased hospitalizations and severe complications .
- Respiratory syncytial virus (RSV) is the most common cause of bronchitis and pneumonia in infants under one year, with an incubation period of 2-8 days .
- Rotavirus, the leading cause of gastroenteritis in children under five, typically spreads through fecal-oral transmission with an incubation period under 48 hours .
- Dr. Cheung warns parents against giving sports drinks to children with vomiting or diarrhea, as high sugar content and improper electrolyte ratios can worsen symptoms—oral rehydration salts should be used instead .
Why It Matters
The back-to-school period creates ideal conditions for disease transmission among children who share toys, desks, and participate in group activities. With multiple pathogens circulating simultaneously, parents face the challenge of distinguishing between similar symptoms. Dr. Cheung stresses that children showing severe symptoms such as breathing difficulty, blue lips, chest pain, confusion, or seizures require immediate emergency care . Early medical consultation rather than self-diagnosis via the internet is crucial for proper treatment and preventing complications.
