Yuan Guoyong said that the Omicron variant is slightly more severe than the seasonal flu virus, but far less severe than the Alpha and Delta variants. Elderly or young children who have not been vaccinated against Covid-19, especially those with chronic diseases, can die from the infection. Adults and children who are vaccinated and do not have chronic diseases, even if they are vaccinated, have only mild symptoms or no symptoms at all. Adults and children with chronic diseases who have not completed the vaccination may have more symptoms, and the results after infection will be in the middle of the two.
He believes that the top priority is to get all eligible Hong Kongers vaccinated as soon as possible. Citizens should wear double-layer masks, outer cloth masks, and inner surgical masks when going out to improve fit and filtering, and should observe social distancing measures.
Yuan Guoyong suggested that if there are unvaccinated young children, the elderly or patients with chronic diseases in the family, one can try to perform a rapid antigen test every other day for each member of the family, so as to prevent one of them from being infected and isolate them as soon as possible. However, if there are not enough rapid antigen tests, consider wearing a double-layer mask even at home and maintain social distancing as much as possible to minimize the exposure of unvaccinated young children, the elderly or patients with chronic diseases to the virus. Close contact, such as kissing and talking, can infect young children. The virus can grow rapidly in young children, and in a small percentage of them, the immune system reacts violently, and the inflammation can be so severe that the brain swells rapidly, leading to a fatal acute necrotizing encephalopathy.
