In a new study entitled “SARS-CoV-2 Nucleic Acid Screening in Nearly Ten Million Residents of Wuhan, China,” the findings appear to be good news in terms of asymptomatic spread and duration of immunity after infection.
According to a study, more than 9.8 million people in Wuhan, China (where they are thought to be descended from COVID-19) were tested between May 14 and June 1 to measure the rate of infection in the community.
Among the findings:
- 9,865,404 participants who had not previously been infected with COVID-1
- 300 people were tested positive but no symptoms (asymptomatic).
- 1174 close contacts of asymptomatic patients, all tested negative for coronavirus.
- There are 34,344 recovered cases of coronavirus.
- Of these, 107 were tested positive again (.310%), but “viral cultures were negative for all asymptomatic positive and repository cases, indicating that there was no ‘viable virus’ in the positive cases found in this study.”
The following is a summary of the study:
Strict control measures for COVID-19 were imposed in Wuhan between 23 January and 8 April 2020. Estimates of the spread of the infection after the release of the restrictions could inform the management of the post-blockade pandemic. Here we describe a nucleic acid screening program for SARS-CoV-2 between May 14 and June 1, 2020 in Wuhan. All residents of the city over the age of six meet the conditions and 9,899,828 (92.9%) participated. No new symptomatic cases and 300 asymptomatic cases were identified (detection rate 0.303 / 10,000, 95% CI 0.270–0.339 / 10,000). There were no positive tests among 1174 close contacts of asymptomatic cases. 107 of 34,424 previously recovered patients with COVID-19 were tested positive again (re-positive percentage 0.31%, 95% CI 0.423–0.574%). Therefore, the spread of SARS-CoV-2 infection in Wuhan is very low five to eight weeks after the end of the blockade.
