Tao Lina, a domestic vaccine expert, told the Global Times that nearly 20 positive patients were found in two days after the Nanjing epidemic, indicating that the epidemic has been going on for some time. According to Taulina's speculation, as a key population, these airport staff should have completed the injection of two inactivated vaccines, otherwise the epidemic may be more serious.
Tao Lina said that most of these patients are mild or asymptomatic, indicating that the vaccine is still effective, highlighting the important role of the vaccine in epidemic prevention and control. Tao Lina believes that in order to increase the protective effect of the vaccine, airport staff can take another shot of the vaccine.
Most of the infected people in this sudden epidemic in Nanjing are airport flight support personnel:
This sudden epidemic in Nanjing began on the morning of July 20th. During routine nucleic acid detection of Nanjing Lukou International Airport staff, 9 cases were found to be positive. Patients are mainly engaged in airport flight support, including 8 airport cleaners and 1 cabin cleaners.
In addition to Nanjing Lukou International Airport, COVID-19 was previously infected by staff at Shenzhen Baoan Airport and Shanghai Pudong International Airport, causing local epidemics.
Jin Dongyan, a professor at the School of Biomedicine of the University of Hong Kong, believes that the Lukou airport epidemic may be a small "super-transmission event". First, individual cleaning staff are infected by infected people or imported pollutants, and then transmitted to other cleaning staff.
