Traceability analysis completed: confirmed that the source of the infection was from overseas foreigners.
Today (October 18), Shanghai disease control department has completed the tracing analysis of Wang’s gene sequencing of asymptomatic infected Huadu. From the perspective of evolutionary relationship, the viral gene sequence of Wang Mou infected with asymptomatic Huadu in Shanghai is highly homologous with the viral gene sequence of imported cases found in the isolation hotel where Wang Mou works, and the main mutation sites are completely consistent. This result is completely consistent with the previous epidemiological survey results. Therefore, it can be absolute affirmations that Wang’s infection comes from the imported cases of isolated hotels.
The investigation of key areas has ended, with a total of 148295 people being investigated.
