Saves us the summer before the Corona pandemic? Experts believe this to be a Problem

At the very beginning of the Coronavirus pandemic could be heard again and again: heat, sun and UV-light to stem the Virus. Everything is in the summer so better? “We’d like to know,” said Susanne Glasmacher, spokeswoman for the Robert Koch Institute. A “certain effect” will give it, the lack of basic immunity of the population, but it is such an advantage for the Virus, it will spread more. A “small effect” is not significant, the head of Virology at the Medical University of Hannover, Thomas Schulz. Also, Clemens Wendtner, chief physician of the clinic for infectious diseases at the Munich, clinic Schwabing, expects a slight Slowdown in the summer, but warns: “We must not fall into the Illusion that we will achieve the higher temperatures, the Disappearance of the Virus.”

According to Melanie Brinkmann, a Professor at the Institute for genetics at the Technical University of Braunschweig, and the virologists Prof. Friedemann Weber pour out the Virus can be destroyed on surfaces with direct sunlight due to heat. The UV component of sunlight can damage its genetic material.

Coronavirus has a better chance to multiply

The Problem: In principle, there is the effect of the summer, although the usual course of Influenza, the flu, show, Schulz said. But the Chance for the new Coronavirus to replicate in a population that was largely immune, is much better. The dose of UV light, the Outdoor feel, little impact. Brinkmann and Weber stated, however, that with Sars-CoV-2 related coronaviruses of humans were the most in the Winter on the an active: “We hope, therefore, that this is also the case for Sars-CoV-2.”

Due to the lack of immunity against the new Coronavirus, all of the disadvantages of the summer was not sufficient for the Virus to push back, also said RKI spokeswoman for glass-makers. You referred to the swine influenza H1N1, which broke out in April 2009, and many of the flu cases have also been triggered in the summer – and well into the following year.

Virus could be stopped, “a little bit” by UV-light and heat

Schulz can imagine that heat and sun can press to light the so-called reproduction number of the Virus – “but only slightly”. This indicates how many people are infected on average by one Infected attached. “Who says that it’s all so bad, all of the cold viruses fell in the summer, I can only say: Dream on!”, Schulz stressed.

The Berlin-based virologist Christian Drosten had said in the NDR Podcast, a pandemic Virus will not stops about social distancing, UV-light and heat is very strong, “but quite a bit”. According to estimates, one-half of a unit could be stripped “” of the reproduction number in summer.

Whether it will come in the next Winter to a re-increase, depends, according to Brinkmann, the number of Infected in late summer and autumn, but also of Test and therapy, interruption of infection chains and “all of our behavior”.

You have to, as long as there is no vaccination, with a flare-up of infections from about October to expect, said Wendtner. May be it will be as is currently the Hotspots, but the Virus will spread throughout the country. “We will carry Covid-19 in the year 2021.” Whether all this can take place for this year’s events – from the Olympic Games cancelled, or next year, moved up to the Oktoberfest then, be open. Schulz asked anyway: “distance, distance, distance.”
