According to a study published on the BioRxiv platform, researchers at the Kyoto Prefectural University of Medicine (Japan) found that the Ômicron variant can survive up to 21 hours on the skin and also 193 hours, which represents about eight days, through plastic surfaces.
Although it has not yet been peer-reviewed, the study was unable to ascertain how far the virus still alive on the surface would be able to infect people. The researchers were able to see more clearly that Omicron is the variant that can survive the longest in plastic.
Check the total hours that each of the analyzed variants is able to withstand on plastic surfaces:
- Ômicron, as mentioned before: 193.5 hours
- Alpha: 191.3 hours
- Beta: 156.6 hours
- Delta: 114 hours
- Range: 59.3 hours
- Original strain: 56 hours
The time that Covid-19 remained on the skin was as follows:
- Omicron: 21.1 hours
- Alpha: 19.6 hours
- Beta: 19.1 hours
- Delta: 16.8 hours
- Range: 11 hours
- Original strain: 8.6 hours
To reach that conclusion, the team tested the survivability of each variant, including Omicron, on a polystyrene (plastic) plate. Afterwards, tests were carried out on samples of human skin collected for forensic autopsy: “In theory, if these particles found on surfaces are contaminants, then this may explain part of the infection process by Ômicron.”
