Low risk of environmental contagion by SARS-CoV-2 in non-sanitary spaces.

OBJECTIVE: To study the presence of SARS-CoV-2 on surfaces (high, medium and low contact) and airs in non-sanitary spaces with high public influx to evaluate the risk of environmental contagion. METHODS: Surfaces and airs were analysed by RT-qPCR to detect the presence of SARS-CoV-2. RESULTS: 394 surfaces and air samples were obtained from spaces with high public influx such as offices, shopping centres and nursing homes. The virus was not detected in any of the samples analysed. CONCLUSION: Although we cannot emphatically conclude that there is no risk of environmental 27 infection by SARS-CoV-2 in non-sanitary spaces, we can affirm that the risk is almost non- existent.
