| Virus überlebt natürliche UV-Strahlung im Winter |  |
Besides geographic and atmospheric ozone, other factors such as topography and cloudiness also play a very important role in the distribution of UV radiation and, consequently, in the inactivation and survival of SARS-CoV-2. Based on the data for December 2019, daily solar irradiation would not be sufficient to reach a level of sterilization across the European continent in the last month of the year. According to the researchers, this may enable the coronavirus to survive long enough outdoors to stay infective for several hours or even over whole days. This is quite different to the situation in mid-April 2020, after the first peak of the pandemic in Europe, when the sterilization of SARS-CoV-2 through solar UV radiation was quite high.
