British Prime Minister Johnson announced on the 21 day, from 24 this month, from the legal sense of lifting all the existing England new crown restrictions, from April 1st onwards will no longer provide free COVID-19 testing for the public. However, this move has attracted many opposition voices in the scientific community. Johnson announced the British government's new plan to "coexist with the new crown" in the lower house of Parliament on the same day. According to the new plan, those who are positive for the new crown test will no longer need to be self isolated, the government will no longer track close contacts, and close contacts who are not fully vaccinated will no longer need to be self isolated. Johnson said that before April 1, the government still suggested that people who tested positive for Xinguan should stay at home for isolation, but after April 1, it was entirely up to the diagnosed person to decide. At that time, the UK will no longer provide free new crown testing for the general public, but will continue to provide free testing for the elderly and vulnerable groups. Johnson said COVID-19 has not disappeared, but "we can now deal with it in a very different way, from government restrictions to personal responsibility". This new plan has aroused strong opposition from many people in the scientific community. Experts say that the premature lifting of restrictive measures is likely to lead to the accelerated spread of COVID-19, which is not based on scientific guidance and violates the basic principles of public health. It will put children, the elderly and other vulnerable groups at risk. According to the recommendations of the British emergency Science Advisory Group, there is still considerable uncertainty in COVID-19. There may be a marked rebound or a more dangerous variant. The British Medical Association said it was too early to lift the restrictions. (Xinhua News Agency)
