Covid-19 will not disappear in the summer

A new study shows that the climate has little influence on the rate of infection for the new Coronavirus SARS-CoV-2. Only if a larger part of the population is immune, it could make an effect on the Climate is noticeable, report the researchers from the Princeton University in the journal Science.

The rapid spread of the Virus in Brazil, Ecuador, Australia and other tropical countries also suggests that warmer conditions will put a stop to the pandemic, because that is where the infection started during the summer season. Model calculations and experiences with other viruses suggest that Covid-19 reacts without a vaccine or other control measures only on a seasonal changes, when the number of infected people is reduced. Further results indicated that the Virus reacts more sensitive to warmer weather, the longer and more consistently distancing measures will be implemented.

The climate has only a small influence

Dr. Rachel Baker said: "We assume that a warmer or wetter climate will not slow down the Virus in the early stage of the pandemic. We see a certain influence of climate on the size and timing of the pandemic, but in General, it will spread the Virus regardless of the climate conditions fast, since the population is so vulnerable."

For the study, the researchers simulated different scenarios for the pandemic in different climate zones around the world would be, and had experience with similar viruses – for example, the flu virus – feed. In all scenarios, the climate was only a mitigating factor when large parts of the human population were immune or resistant to the Virus.
