Resumen
BARRERA-NUNEZ, David et al. Rapid review of transmission of SARS-CoV-2 by contact with objects and surfaces. Salud pública Méx [online]. 2021, vol.63, n.1, pp.126-135. Epub 15-Ago-2022. ISSN 0036-3634. https://doi.org/10.21149/11877.
Objective:
To identify scientific evidence on the indirect transmission of SARS-CoV-2 in out-of-hospital spaces and population measures for its prevention.
Materials and methods:
A rapid review of what has been published in PubMed and MedRxiv between 12/01/2019 and 04/24/2020, on the topics: 1) the contamination and viability of SARS-CoV-2 in different inanimate surfaces; 2) products accessible at home level with disinfectant efficacy against SARS-CoV-2; 3) the cases and outbreaks of SARS-CoV-2 transmitted through surfaces.
Results:
A high proportion of the objects people infected with SARS-CoV-2 use (toilet, pots and electronic tablets) are contaminated. This virus remains viable from hours to days in paper, cardboard, cloth, glass, wood, plastic, steel and face masks. Ethanol, 2-propanol, chlorine, and soap are effective in deactivating it. There is little evidence on cases and outbreaks by indirect contact.
Conclusions:
Studies are required to determine the minimum infectious dose by autoinoculation. Appealing to the precautionary principle, we include recommendations to reduce the risk of indirect contagion.
