ABSTRACT
Objective To analyze the detection of SARS-CoV-2 in household environment and public place environment of Huangpu District, and describe the feature of SARS-CoV-2 contamination in the environment exposure to the infected cases, so as to support the control strategies such as disinfection and health communication. Methods The results of RT-PCR test for the environmental samples exposure to the cases infected by SARS-CoV-2 during February 1 to March 31 2022 in Huangpu District of Shanghai were collected as the research data. Pearson χ2 was used to test the significance of the differences between positive rates of SARS-CoV-2 contamination. Results From February 1 to March 31, household environment samples had a higher positive rate (6.47%, 234/3 618) of SARS-CoV-2 contamination while the public place samples had a lower one (1.22%, 47/3 582) in Huangpu District of Shanghai (χ2=141.908, P<0.01). Among the household buildings, the lane houses of old style representing poorer living condition had the highest positive rates (8.31%, 96/1 155) of SARS-CoV-2 contamination while the apartments representing better living condition had the lowest (3.59%, 22/612) (F=5.25 P<0.05). Among the samples from household environment, samples regarding sewerage had the highest positive rates (13.30%, 58/436) of SARS-CoV-2 contamination, while samples regarding the tool of cooking and sweeping had the lowest (3.10%, 17/548) (F=9.84 P<0.01). Among the samples from public place environment, samples regarding entertainment tools had the highest positive rates (13.33%, 2/15) of SARS-CoV-2 contamination, while samples regarding the tool of cooking and sweeping had the lowest (0.62%, 4/646) (F=4.22 P<0.01). Conclusion In the environment exposure to the SARS-CoV-2 infected cases, the disinfection, ventilation and cleaning should be intensified strictly. SARS-CoV-2's surviving in sewage environment should be evaluation dynamically. More health communication should be pushed to people of poorer living condition. © 2022 Editorial Office of Chinese Journal of Schistosomiasis Control. All rights reserved.
