Gelonghui, April 24, 丨 The tourism sector fell collectively, tourism in the western region fell to a standstill, tourism in Tibet and Xi'an fell 6%, Huatian Hotel fell 5%, and Jinjiang Travel, Zhongxin Travel, and Junting Hotel fell 4%. Jin Dongyan, a professor at the School of Biomedical Sciences at the Li Ka-shing Medical School of the University of Hong Kong and a virologist, said that the increase in the movement of people during the “May 1st” holiday caused a slight increase in the epidemic. Currently, there is no soil or conditions for a large-scale COVID-19 epidemic in the country. Jin Dongyan said that recently it was discovered that the XBB.1.16 strain that has just been introduced into China is a strain derived from BA.2. There has been no significant increase in pathogenicity, so there is no need to worry too much. Judging from COVID-19 trends in many countries and regions around the world, the possibility of a local or large-scale global outbreak caused by XBB.1.16 in the future is minimal.
