Test one

——The spread of the transmission chain, the footprint of the infected person involves many places

  With the advancement of nucleic acid testing for all employees in Nanjing, the number of newly confirmed cases in Nanjing increased significantly in the past two days. In the two days on the 25th and 26th, the number of newly confirmed cases in Nanjing exceeded 30, and the number reached 47 on the 27th.

  From July 20th to 27th, Nanjing City reported a total of 153 local confirmed cases, including 81 cases of light type, 68 cases of normal type, and 4 cases of heavy type.

  According to incomplete statistics, in more than a week, the epidemic transmission chain has spread to more than 10 cities in 5 provinces, including Jiangsu, Anhui, Guangdong, Sichuan, and Liaoning, where infected people have appeared.

  In addition, the footprints of the infected and close contacts also involve other provinces.

At present, close contacts and sub-close contacts have been found in Taizhou City, Zhejiang Province.

The infected person in Dalian had traveled to Zhangjiajie and the ancient city of Phoenix in Hunan. In addition, they had also transited in Xianyang, Xi'an.

  The number of cases is increasing rapidly, and the epidemic "spillover"... Whether all infected persons can be detected in the shortest time and the spread is controlled is the biggest test.

On July 26, the Nanjing "Fire Eye" laboratory was stepping up its construction at the Nanjing International Expo Center, with staff debugging equipment.

Test two

——Delta mutant with stronger transmission ability

  At the press conference on the prevention and control of the new crown pneumonia epidemic in Nanjing on the 27th, the traceability results of the epidemic were announced-the strain causing the epidemic is the delta mutant strain.

  Ding Jie, deputy director of the Nanjing Centers for Disease Control and Prevention, introduced that the delta mutant strain that caused the epidemic has a strong spreading ability and a fast spreading speed.

The particularity of the place where the epidemic occurred has also led to a further expansion of the spread.

  In the face of mutated strains with stronger transmission capacity, only expanded control, intensive screening, and early detection of cases can effectively deal with them.

Test Three

——Typhoon "fireworks" struck, epidemic flood situation superimposed

  Severe weather conditions were accompanied by the outbreak.

The floods in Henan are still ongoing, and the No. 6 typhoon "Fireworks" has landed again this year.

  From the 25th, the impact of typhoon "fireworks" on Nanjing has continued to increase.

According to a message from the Nanjing Meteorological Bureau, the "firework" center has entered the territory of Nanjing after 10 o'clock on the 27th.

In the afternoon of the same day, the Nanjing Municipal Meteorological Department issued a yellow warning of heavy rain.

  Data from the Meteorological Department showed that during the strongest rainfall period on the 27th and night, the rain intensity in Nanjing was 51.7 mm in 1 hour and 144.6 mm in 6 hours.

It is expected that there will still be moderate to heavy rains in the city on the 28th, with southeast winds of magnitude 5 to 6, and gusts of magnitude 7 to 8.

  Faced with the dual challenges of epidemics and extreme weather, how to prevent and reduce disasters while taking into account epidemic prevention is the key.

Test four

——It is difficult to overlap the epidemic and summer travel

  The outbreak of the epidemic in Nanjing this time coincides with summer travel and summer vacation, and is the peak period of personnel travel and mobility.

  Nanjing Lukou International Airport, where the epidemic has occurred, is "an important hub for the world-class airport cluster in the Yangtze River Delta", which also makes it difficult to stop the spread of the virus.

  After the outbreak, Nanjing City has successively upgraded a series of prevention and control measures.

  This includes, before leaving Nanjing, all types of personnel must provide a green code of health code and a certificate of negative nucleic acid test within 48 hours; strict access control in all communities; suspension of operation of 8 long-distance passenger stations in the city; suspension of airtight KTV, movie theaters, gyms, etc. The premises are open, and so on.

Under the epidemic situation, Nanjing is facing numerous challenges.

Must win, and must win!
