The schools have been disinfected and closures are to stop the illness spreading any further. People in Hong Kong are worried because in 2003, almost 300 people there died because of SARS (Severe Acute Respiratory Syndrome).
SARS can make people really ill like a cold or flu and can die if not treated quickly. But health officials say the recent outbreak of illness appears to be a normal type of flu. SARS is very rare and health officials say people in the UK are very unlikely to catch it.
