The weather and temperature are abnormal.

This is because the number of floating population in Chongqing is relatively large. After the power shortage in Chongqing, the high temperature weather in Chongqing may lead to signs of a rebound in the epidemic.

As far as Chongqing is concerned, Chongqing itself has rich experience in prevention and control. After the appearance of confirmed cases, Chongqing has organized all personnel to carry out nucleic acid testing as soon as possible, and at the same time, it is also closely checking the traces of confirmed patients in COVID-19, which can further prevent the spread of COVID-19 epidemic. To a certain extent, the COVID-19 epidemic was discovered earlier in Chongqing, and the prevention and control measures of COVID-19 epidemic in Chongqing were also very good, so the local COVID-19 epidemic was initially controlled.

There are 23 confirmed cases in Chongqing.

After finding signs of rebound, the number of confirmed cases in Chongqing was 23, and there were also 8 asymptomatic infected people. Of all the patients, 1 batch of patients were imported from abroad to Chongqing. 1 Example has been to Laos, 1 Example has been to Hong Kong, and 2 cases have been to Singapore.

The epidemic situation in Chongqing was caused by imported cases from abroad.

For this wave of COVID-19 epidemic, although there are no confirmed cases of COVID-19 in Chongqing, Chongqing itself has a large population, and imported cases from abroad have led to the emergence of COVID-19 epidemic in Chongqing. To some extent, imported cases from abroad are the main reason for the rebound of epidemic situation in many cities. Especially in cities like Chongqing, because Chongqing has a large number of people traveling abroad every day, if foreigners don't do a good job in nucleic acid testing and COVID-19 screening, these people can really bring the COVID-19 epidemic to the local area.

Finally, I personally suggest that cities closely investigate the possibility of imported cases of infection. For all first-tier cities and second-tier cities, the rebound of COVID-19 epidemic will affect people's basic life, and even affect the industrial production of relevant cities. We need to try our best to prevent imported cases in all cities.
