First, compare the figures for the two days in Shanghai. The day before yesterday (April 27), Shanghai added 1,292 local confirmed cases (including 858 previously asymptomatic infections turned into confirmed cases) and 9,330 asymptomatic infections. Among them, 432 confirmed cases and 9,140 asymptomatic infections were found in isolation and control, and the rest were found in the investigation of relevant risk groups.
That is, only 2 confirmed cases and 190 asymptomatic infections were found in the “relevant risk population screening”. This is social transmission, and the numbers have begun to fall to a relatively low level.
If the 858 cases of asymptomatic people turned into confirmed cases are subtracted, there were only 9,764 new infections found on that day.
Since April 22, the number of new positive cases in Shanghai has been decreasing for 6 consecutive days. According to the figures in recent days, the effect of the closure of the city is more significant. The decrease of 20% on the previous day and the decrease of 22% on the 27th compared with the previous day, not only the actual number of infections has dropped, but the decline is expanding, which shows that the epidemic is gradually under control. The resumption of work and production in Shanghai has been started in batches.
Friends who are worried about the Shanghai epidemic getting out of control can breathe a sigh of relief. When the mainland uses the two tools of foot restraint and full-staff testing together, even the spread of the epidemic can be controlled.
