(A) Survival times of the various viruses on a plastic surface. (B) Survival times of the various viruses on the surface of human skin. (C) Half-lives of the various viruses on a plastic surface. (D) Half-lives of the various viruses on the surface of human skin. Survival time is defined as the time until the virus can no longer be detected on the surface. All half-lives in the graphs refer to a condition when 2.0 and 3.0 Log₁₀TCID₅₀ (50% tissue culture infectious dose) of virus particles remained on the surface. Data are expressed as the median ±95% confidence interval.
