Δ virus is the most important variant in COVID-19 in the world. Compared with other strains, Delta strain has stronger transmission ability. This means that with the extension of the COVID-19 epidemic, COVID-19 is also growing. Delta virus spreads faster, and may spread for four or five generations in just a few days. Moreover, Delta virus is more hidden and difficult to detect, and many infected people may not be diagnosed by one or two nucleic acid tests.
The epidemic situation in Putian has brought people a warning. At the initial stage of the epidemic, people in close contact only need to be isolated 14 days. With the spread of the epidemic and the escalation of the virus, the hiding ability of the virus is getting stronger and stronger, and the isolation period of only 14 days can no longer meet the needs of anti-epidemic. The source of the epidemic was even hidden for more than a month, which brought great difficulties to China's epidemic prevention work. It is necessary not only to extend the isolation period, but also to carry out multiple tests. Many infected cases in Putian are children, with as many as 30 children under the age of ten. It is difficult for every adult to watch these young children go to the examination alone and endure the pain.
Make epidemic prevention measures routine. Although the epidemic situation in China has been well controlled, it is far from over. From last year to this year, the virus was silent in China for a period of time, and then broke out in Nanjing. From Nanjing to Yangzhou, and now to Putian, the virus has been active in a small area in China. Everyone must actively cooperate with the government in order to nip the epidemic in the bud. Wear a mask when you go out, wash your hands and disinfect frequently when you go in and out of public places, and seldom go to a closed environment. Only if each of us does a good job in epidemic prevention can we firmly control the epidemic situation in a low-incidence state.
