Due to the serious rebound of the epidemic situation in COVID-19, many areas in Britain began to implement the most stringent epidemic control measures. Greater manchester began to implement the highest and third level epidemic control measures in England, while Liverpool and Lancashire are already at the highest level of epidemic control.

South Yorkshire will also enter the third level of control. In addition, Warrington has been moved to the third-level epidemic control list and is expected to be implemented next week. Nottingham and other places may also be moved into the third-level epidemic control list next week. The specific contents of the three-level control measures include: pubs and bars that do not provide meals are closed, people from different families are not allowed to meet indoors or outdoors, and the government guides travel in and out of the area.

Poor epidemic prevention is one of the reasons for the surge in cases.

The last wave of epidemic was Omicron's ba. 1, but the mutant ba.2 brought a new wave of epidemic, which is one of the reasons for the increase of cases again. However, experts and scholars believe that ba.2 will not trigger another wave of epidemic. Mehul Sutal, a virologist at Emory University, said that although ba.2 is highly contagious, whether it can trigger another wave of epidemic depends on whether it can infect people who are immune to the virus, including those who have been infected with Omicron and recovered.

Lawrence Yang, a professor of molecular oncology at the University of Warwick, said in an interview that the factors related to the increase in cases are more likely to be lax epidemic prevention, leading to more social gatherings and fewer people wearing masks. In other words, the reason for the rebound is that the number of new cases has not bottomed out. Once epidemic prevention is liberalized, the number of cases will increase.
