The serious reasons of the epidemic situation are as follows: 1, the virus has strong transmission, fast transmission speed, strong concealment and short incubation period.
2. Yiwu has a large floating population, great mobility and frequent personnel contacts and exchanges.
3. The trajectory of some cases is complicated.
Since the "8.2" epidemic in Yiwu, 500 cases of positive infection in COVID-19 have been reported, including 4 confirmed cases in COVID-19 and 459 asymptomatic cases in COVID-19.
