Then these samples were placed Plastic boxes and human skin of carcasses at a temperature of about 77 degrees. In the first element, the original Wuhan variant survived for a few 56 hoursWhile the other strains – Alpha, Beta, Delta and Micron – survived until more than three timeswith the outstanding performance of this latest boom: It lasted for 193 hours (8 days).

In addition, the human skin test yielded the following results: the original strain from Wuhan, 8 hours; Other strains (alpha, beta and delta) More than 16 hours; Micron strain, 21 hours.

For its part, the study was conducted in Hong Kong – which is also awaiting peer review – Various tests on plastic, paper, glass and stainless steelThe results were similar: The Micron remained active for more hours than the other breeds.
