Winter Vomiting Bug and Norovirus are the same!
It is more likely to occur in winter, foreign countries call it Winter Vomiting Bug. Norovirus typically causes symptoms of gastroenteritis that resolve on their own. Symptoms include nausea, vomiting, diarrhea without blood, and abdominal pain. In addition to ingesting contaminated food and water, infection can occur through person-to-person contact, contact with contaminated objects, and aerosolized vomitus. Groups with weakened immune systems such as pregnant women, infants, young children, and the elderly are more susceptible to infection.
Prevention 1. Keep clean and hygienic
Always keep your hands clean, especially before handling or eating food and after going to the toilet. As the virus may be transmitted by contaminated vectors, patients or carriers should avoid handling food and caring for children, the elderly and those who are immunocompromised. When cleaning or handling vomit and feces, gloves and a surgical mask must be worn, and hands must be washed thoroughly afterwards.
Prevention 2. Pay attention to the hygiene and safety of food
Avoid raw food, especially shellfish, or unpasteurized food that contains raw materials that will not be cooked. Oysters are considered to be the most common food causing norovirus food poisoning outbreaks in Hong Kong.
