Hong Kong health authorities have issued a warning due to a significant rise in norovirus-related food poisoning cases since January 18. The Centre for Health Protection reported 23 food poisoning incidents, affecting 69 people, with 20 cases involving 57 individuals linked to raw oyster consumption. Investigations revealed the oysters originated from various countries, including Korea, France, Ireland, and Spain. Health officials advise vulnerable groups, such as pregnant women, young children, the elderly, and those with weakened immune systems or liver disease, to avoid eating raw or partially cooked oysters to prevent infection. The increase is drastic, with 16 cases reported in the first five days of February alone, compared to about one case per week in late December.
