Warm, cold, damp? What Viruss Need for Survival

Will the Corona virus be eliminated by temperature increase? Virologist Thomas Pietschmann explains why spring really gives us hope and why women are clearly at an advantage in fighting virus disease.

Hope is, in the spring everything will be better. If it goes well, the new coronary virus known as SARS-CoV-2 will have the same fate as the flu virus. Spring with rising temperatures would end it, and thus all this tension would pass. The coronary virus season would fade just like the flual wave, which ends every year at the end of winter.

So much for hope. But if the SARS-CoV-2 virus is going to have the same mutation as you want, it can't be said with the correct precision that even virologists point out that Thomas Pietschmann “was strictly viewed and can't honestly predict that, because we don't know this virus. ”

Pietschmann is a molecular virologist and studies at the Centre for experimental and clinical studies of infections called Twincor, in Hanover. He deals with the so - called RNA viruses he belongs to. and hepatitis C virus. SARS-CoV-2 is also part of this group.

Virus? Unknown!

The particular “in this virus is, that man is confronted for the first time. From the data that we have from China, you can conclude, that the virus has only once passed from one animal to the human being has thus spread “, says Pietschmann.

In other words, unlike the viruses of influence, with which almost everyone has contacted once, our immune system is not prepared for a coronary attack.

This adds to the fact that the northern hemisphere is actually perfect for the rapid spread of viruses. On the one hand, it's temperature. Aspiring viruses - those spread through the respiratory system - are very easy when it is cold. “Virus has high stability when temperatures are low. Like food, which stays in the refrigerator the longer”, Pietschmann explains.

Cold and said, please!

The warmer it gets, the harder conditions become for viruses. “Virus Corona is surrounded by an ipide layer, so fat”, says Pietschmann. This layer does not resist the heat, and the temperature - growing virus will soon die. Other “Virus, like that noro, are more sustainable, because they are made up of proteins and hereditary molecules. ”

Other viruses also play secondary roles. Degu's viruses appear mainly in tropical and subtropical regions. This is not about what they prefer heat, but about the fact that warm areas are the habitat of mosquitoes that transmit this virus. The main role in the spread of this virus is not the temperature, but the insect or animal that transmits the virus”, says Pietschmann.

Air pollution also plays a role in delivering respiratory viruses. If viruses come out through a strong test from the person affected by them, they stay in the air. In the cold days, the buds from breathing with the viruses inside stay longer in the air than when the air is wet”, says Pietschmann.

In this way viruses spread very quickly. First, however, they spread in silence and in secret. From the first contact with the virus to the first symptoms may be several weeks. Incubation duration depends on the characteristics and biology of the virus.

Double Chromation X and estrogens

Temperature, pain, and trembling are the typical symptoms of a viral disease, and the signs that the body fights the viruses that have penetrated it. The success of this war depends not only on age and health but also on sex. Even in the case of the coronary virus, the figures speak, that women have a better chance of coping with men. The mortality quota in men at 2.8 percent is evidently higher than in women by 1.7 percent.

This has on one side the genetic reason”, says Pietschmann, “because some genes relevant to immunity, for example. The genes that are responsible for knowing the molester are encrypted in the X.” chromosome Since women have two X chromosomes and men only one then female gender is to the advantage of being more protected.

The female estrogen hormone also helps women to protect themselves against viral diseases. Some relevant genes in the immunologic direction also have linked elements for estrogens, where these genes are activated. This means that these genes are also commanded by hormones”, explains Pietschmann.

Perhaps the corona season will close at the beginning of spring in the Northern Hemisphere. According to the World Health Organization, meanwhile, a case has been recorded with SARS-CoV-2 in Brazil, in the southern hemisphere, where winter is expected to begin.
