High heat and humidity could weaken the coronavirus, according to a study

high-heat-and-humidity-could-weaken-the-coronavirus-according-to-a-study


The idea that the new coronavirus could decrease in intensity during the summer has long been debated. In fact, it is the reaction of the coronavirus to high temperature and humidity. One study found that it weakens in such an environment.


The research was conducted by the National Biodefense Analysis and Countermeasures Center at the request of the US Government. Specialists observed a regressive reaction of the virus to strong sunlight.


High heat and humidity could weaken the coronavirus

In fact, the sun kills the virus on surfaces and in the air. "Our most striking observation to date is the strong effect that sunlight appears to have on killing the virus, both on the surface and in the air," a Homeland Security spokesman, Bill Bryan, wrote Thursday. 

"I saw a similar effect on both temperature and humidity. The increase in temperature or humidity or both is generally less favorable to the virus, "the official added.


Does the virus weaken when summer comes?

Scientists have been researching the possibility of the virus weakening since the temperature rose with the arrival of summer in the northern hemisphere.

"We identified one of the weak links in the chain of virus transmission. We have identified that humidity and heat are weak elements in this chain. We have identified that sunlight, UV rays are a weakness in this chain ", insisted Bill Bryan, an expert in Science and Technology at the Department of Homeland Security.


80% humidity is almost fatal for Covid-19

To support his claims, the expert presented some data in figures from the study - conducted by the National Biodefense Analysis and Countermeasures Center.


According to these data, the half-life of the virus - the time required to halve its power - is 18 hours at a temperature between 21 and 24 degrees Celsius and a humidity of 20%, on a non-porous surface. These are surfaces such as door handles.


But this half-life is reduced to six hours, when the humidity level rises to 80% and to only two minutes when sunlight intervenes in the equation.


When the virus is suspended in the air, the half-life is one hour, at a temperature of 21 to 24 degrees Celsius and 20% humidity.

At the same humidity level and temperature, but in sunlight, this duration decreases to a minute and a half. Bill Bryan concludes that summer could create "an environment in which transmission can be reduced." But that doesn't mean the pathogen is completely eliminated.


And the results of this study alone cannot justify a lifting of the social distancing measures in place in the United States, he warned. Previous studies have shown that the virus survives better in cold and dry weather than in heat and humidity.


However, US health authorities believe that even if the number of new coronavirus infections decreases over the summer, the level of infection is likely to rise again in the fall and winter - as is the case with seasonal viruses.

coronavirus-should-you-actually-wear-gloves-when-shopping

If you've seen a lot of people wearing gloves while shopping and listened to, like each of us, the authorities sending official messages on how to protect ourselves from the spread of coronavirus, you probably already wonder if you should do that when you go shopping.


 Many of the few people we meet these days usually wear either surgical gloves or household gloves, or even crocheted gloves when shopping.  But is it true that you are safer if you are wearing shopping gloves?


 Experts say that the supermarket is not necessarily among the most dangerous places you can be in these days, and some specialists even go so far as to claim that wearing gloves when shopping is really doing you more harm than good.  


 First of all, this is because gloves behave exactly like your hands without gloves.  The new coronavirus does not reach our bodies through our hands - so this is not where we need to protect ourselves.  If we touch a contaminated surface on the drops of another person, and then touch anything else, we can only spread the virus, whether or not we have gloves.  Indeed, experts warn, it is very likely that the virus will adhere to a latex surface rather than to human skin. And the skin is immediately washed with soap and water, which you may not have been tempted to do as soon as you enter the house after wearing gloves for shopping, but which is essential for prevention.




And that is precisely the problem with wearing gloves for shopping or anywhere else these days.  That they can give you a vague sense of security, which is not at all justified. And if you go to more places and touch more things that you do not necessarily need to touch, just because you feel protected, it is very possible to spread the virus.  Just think that if you go shopping with your bare hands, you probably wipe them with a pocket disinfectant or an alcohol wipe before you go, say, and at the pharmacy.


And then, public health experts warn, most of us do not know how to properly remove our gloves, as health professionals would do, much more familiar with these hygiene rituals.  Even medical staff have difficulty in accurately following the steps to ensure that they are protected.

a-cat-spent-40-days-alone-due-to-quarantine-she-managed-to-survive-and-even-give-birth-to-kittens

In the Chinese city of Wuhan, a cat spent 40 days at home alone, due to the fact that its owners were infected with coronavirus and were hospitalized.


 The owner of a British shorthair cat named Le-Le said that his entire family of seven people became infected with the coronavirus on the eve of the Chinese New Year.  By that time, the cat was at the last stage of pregnancy. When all family members were hospitalized, the owner of Le-Le did not ask others to look after the cat, because in his apartment it was possible to get infected of the deadly infection.


 As a result, Le-Le was left alone in an empty apartment.  The cat managed to survive thanks to two open bags of food that its owner had left before leaving for the hospital.

“I keep turtles and fish at the balcony in the aquarium.  There was also filtered water that the cat could drink !, ”the owner explained.


 Together with his wife, he closed all the windows and doors, in addition to the balcony, before leaving for treatment.


 “After that, we had no idea what was happening in the apartment,” he admitted.


 After 40 days, his wife was discharged from the hospital.  She returned home and found that Le-Le gave birth to four kittens and feels great.  However, the pet ate all the fish in the aquarium.

why-do-some-healthy-young-people-die-from-coronavirus-the-specialists-have-two-explanations

Covid-19 "attacks" the most powerful of the elderly, but even young and apparently healthy people do not get rid of coronavirus.  The news about the death of some adolescents, young people without previously diagnosed health problems has shocked us in recent weeks.  Why do some healthy, young people die from the new coronavirus? The specialists have two explanations, which will be deepened by thorough research.


 It remains one of the biggest mysteries of the current Covid-19 pandemic.  In general, the disease causes severe complications to people past the age of 65 and those with certain conditions, such as cancer, diabetes, high blood pressure or obesity.  However, there were also casualties among young people without health problems, including among medical personnel. In some cases, after the death, certain conditions with which the victim had not been diagnosed, in other words, was not known to be sick.

The researchers are facing this huge challenge, to discover the cause of the strange behavior of the coronavirus.  Several theories have already been put forward. Some researchers believe that the amount of virus we are infected with is extremely important: we have been exposed directly and strongly, the complications can be serious.  "A person with a high viral load has more virus particles than a small virus," says virusologist Alison Sinclair of Sussex University.

 "We still do not know what the impact of viral load is on the symptoms of a person infected with Covid-19.  It will be important to find out if there is a link between large viral loads and serious cases, ”added Sinclair. 


 In addition, the first data from China suggest that viral load is higher in patients with a more severe form of the disease, as is the case with SARS and influenza.

But other researchers argue that the main explanation lies in genes.  Some of us are simply genetically predisposed to develop the most serious forms of Covid-19.  Virology expert Michael Skinner from Imperial College in London explained, quoted by the Guardian: "It is quite possible that some of us may have a genetic particularity that will make us react much worse when we are infected with coronavirus."


 "It may be a similar sensitivity of some people with Covid-19, and this makes them more acute due to serious side effects," Skinner added.


 An example of such sensitivity is given by the herpes simplex virus.  In some people, a genetic mutation that affects TLR3 cell receptors in the central nervous system makes them unable to react to the worst stroke of the virus, so they make a disease called herpex simplex encephalitis that can lead to seizures.
