Abstract:
Objective:To investigate the survival of 2019 novel coronavirus (2019-nCoV) on the surface of inanimate objects at different temperatures.Methods:CNKI, WanFang Database, VIP, PubMed, Web of Science, Cochrane Library and Embase were searched for articles published from January 1, 2020 to June 15, 2022 with "2019-nCoV, surface, inanimate, environments, environmental, matrices, factors, conditions, contact, personal protective equipment, transmission, stability, persistence, viability, survival, survivability, infectivity, transmission". The literature was screened according to the inclusion and exclusion criteria. After the data in the literature were extracted, the improved MINORS scale was used to evaluate the literature quality. RevMan5.4 software was used for meta analysis, and Stata17.0 software was used for Begg′s test and Egger′s test to evaluate the publication bias.Results:A total of 20 studies were included. Meta-analysis result showed that the survival ability of 2019-nCoV on the surface of non-porous objects (stainless steel, glass and plastic) was significantly different from that on the surface of porous objects (cloth, wood board, banknote, cotton, cardboard) ( Z=5.94, P<0.001; Z=17.85, P=0.004; Z=38.20, P<0.001). The result of subgroup analysis showed that there was no significant difference in the survival ability of the virus between banknotes and glass, plastic surfaces under the same conditions ( Z=0.81, P=0.420; Z=1.79, P=0.070). The half-life of the virus at 4 ℃ was significantly different from that at 25 ℃[ MD=47.49 h, 95% CI: 7.00~87.99, Z=2.30, P=0.020]; The half-life of the virus at 25 ℃ was also significantly different compared with that at 35 ℃[ MD=5.46 h, 95% CI: 0.13~10.78, Z=2.01, P=0.040]. Conclusions:Under the same conditions, the survival time of 2019-nCoV on the surface of nonporous objects was longer than that on the surface of porous objects, and the higher the temperature, the shorter the survival time.
