Monitoring SARS-CoV-2 in air and on surfaces and estimating infection risk in buildings and buses on a university campus

Epidemiological characteristics and transmission dynamics of the outbreak caused by the SARS-CoV-2 Omicron variant in Shanghai, China: A descriptive study

“…Moreover, residents may still have been exposed to the virus inside their buildings. 34 It is thus important to carry out quantitative evaluations of the unavoidable risks posed by the adopted strategies. Empirical evidence from Shanghai shows that it is possible to maintain containment policies against the highly transmissible Omicron BA.2 variant, although this required unprecedented efforts to achieve.…”

SARS-CoV-2 surveillance with environmental surface sampling in public areas

“…Environmental surface surveillance is a useful public health tool that has been used for detection and mitigation of various infectious diseases. In their environmental surface sampling study, Zhang et al [ 30 ] detected SARS-CoV-2 on university campus surfaces, indicating that routine and multidisciplinary environmental surveillance approaches should be used. Cheng et al [ 31 ] sampled 377 environmental surfaces in a hospital, and found a 5% SARS-CoV-2 positivity rate.…”

Stability of SARS-CoV-2 on inanimate surfaces: A review

“…The studies of Cheng VC et al ( Cheng et al, 2020 ) and Kim UJ et al ( Kim et al, 2020 ) both sampled medical environments and found that the surface positive rate was 5% and 3%. While, the study of Zhang X et al ( Zhang et al, 2022 ) sampled in non-medical environments (classroom, office, cafeteria, bus, gym, etc.) and found that the positive rate was only 1.5%.…”
