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.

thanks-to-coronavirus-the-world-is-getting-cleaner-and-environmental-friendly

The measures undertaken by various countries to put people under stringent lockdowns to stop the spread of the coronavirus have experienced an unforeseen and unique benefit. The outbreak has, at least in part, contributed to a noticeable drop in pollution and greenhouse gas emissions in some countries.


“Since the lockdown: Venice's canals have become crystal clear. Italy's coasts have dolphins coming nearer and nearer. Japan now has deer roaming free in the streets, and Thailand: the same with monkeys. China has record-breaking pollution cuts. The Earth has already begun showing signs of amazing things that are happening from the absence of human pollution. What if- and hear me out..- what if the entire human population used this as an opportunity to restart society on a greener, more environmentally conscious foot. What we're seeing in the span of a couple of days is amazing. A pipe dream.” Gina Mayer

The drastic measures enforced by China during the coronavirus outbreak have slashed deadly air pollution, potentially saving the lives of tens of thousands of people, a Stanford University researcher said.


Klopp said the pandemic could make companies and governments realize that other threats to humanity, including climate change, could be the most devastating and harmful.

"As we move to restart these economies, we need to use this moment to think about what we value," she said. "Do we want to go back to the status quo, or do we want to tackle these big structural problems and restructure our economy and reduce emissions and pollution?"


Now we must realize the harmful impacts we made to our planet are the deadliest one, we must understand that we have to stop pollution and finally start being friendly to our planet.

Is the pandemic virus a sign to stop humans actions against planet?

Let’s think about this one more time.

how-to-prepare-your-own-chlorine-disinfectant-recipe-at-home

Chlorine based disinfectant is one of the most powerful solutions that eliminates coronavirus from surfaces.  The recipe is very simple and you can try it right at home. Here's what you have to do!


If you want to prepare your own disinfectant with which to sanitize your home, you will need to be very careful about how you use chlorine.  Because it is a caustic substance, it should not be mixed with other solutions, but diluted only with water, in appropriate proportions. Here is the exact network and what you need to do!


 How to prepare your own chlorine disinfectant.  Recipe for home

 The American Center for Disease Control recommends disinfecting surfaces in our home - tiles, wall tiles, linoleum, door handles, etc. - using a chlorine solution with a concentration of 1:50, ie 20 ml of chlorine per liter of water.  This disinfectant, properly prepared, sanitizes surfaces and objects that we come into contact with daily, but does not affect our health. If you think this amount of chlorine is small, find out that it is actually more than enough for the complete elimination of coronavirus.


 The tools you need:


 You will need a spray container where you can keep the solution;

 A graduated container to make the necessary measurements;

 Household rubber gloves;

 A nose and mouth protection mask.  This way you will avoid inhaling chlorine vapors.  If you do not have a mask, you can use a scarf, a handkerchief, a handkerchief, any textile material that will prevent you from inhaling the vapors;

 Water;

Chlorine;


Recipe for daily use


 First of all, you must know that the disinfectant is prepared outdoors, or, if you do not live at ground house and do not have a yard, go to the balcony.  If you do not have a balcony, prepare the solution in a very well ventilated room, with the windows wide open. Chlorine releases extremely toxic vapors. To make a solution with a concentration of 1:50 you need 20 ml of chlorine in 1 liter of water.  Pour water into a basin, add chlorine, mix and use the solution for washing on the floor or for disinfecting other objects. The disinfectant can be used daily, and if it is more concentrated, it should be used once a few days.

 The chlorine-based disinfectant is prepared according to a very simple recipe, but we must pay close attention to the quantities of chlorine and water we use.  It is the most important aspect. If not, chlorine could seriously affect our health.

boris-johnson-tests-positive-for-coronavirus

U.K. Prime Minister Boris Johnson has tested positive for the coronavirus, he announced this on his personal page on social media.


Johnson mentioned in a video that he has "mild symptoms" of coronavirus, including fever and "a persistent cough." Johnson is the first world leader found to be infected with the virus. 

German Chancellor Angela Merkel decided to be under self-quarantine after her doctor was found infected with the coronavirus. She has undergone two tests that were confirmed negative, but there are awaiting results for the third test.

Johnson and Merkel said that they will continue to work from home, being self-isolates.


"Over the last 24 hours I have developed mild symptoms and tested positive for coronavirus," Johnson said via Twitter. "I am now self-isolating, but I will continue to lead the government's response via video-conference as we fight this virus. Together we will beat this."


If Johnson would not be able to accomplish his official duties, his role would be temporarily done by Dominic Raab, the U.K.'s foreign secretary and first secretary of state.


On the same day, some hours earlier the British health minister Matt Hancock, announced on his Twitter page that he is self-isolating at home with mild symptoms after he has tested positive for coronavirus.

The U.K. currently has over 12,000 confirmed cases of coronavirus, and 580 people have died from COVID-19, according to data compiled by Johns Hopkins University.

a-collection-of-5-fascinating-facts-about-the-1918-flu-pandemic

(1)Five hundred million people, in other words the third part of the entire world's population, were infected and fell ill.

 The "Spanish" influenza pandemic of 1918–1919, which caused approximately 50 million deaths worldwide, remains an ominous warning to public health. The disease was exceptionally severe. 

(2) The president of the United States, Woodrow Wilson that time, caught the flu— and so did future president Franklin Delano Roosevelt.

 Wilson felt bad during the Paris Peace Conference in 1919, he was negotiating the future path for the world after World War I. If he'd died during this times, it would have dramatically changed the future of many states. Wilson's daughter Margaret and much of his staff also got sick. Roosevelt — then the assistant secretary of the Navy — was infected while on a voyage to France aboard the USS Leviathan. Roosevelt survived the flu after being returned home to the States.

(3) The pandemic came to be known as the "Spanish flu," but it didn't actually start in Spain.

When the flu first hit Europe in early 1918, it spread throughout military camps on both sides of World War I. Even if it was going fast, governments involved in the war kept it a secret because they feared that acknowledging their troops were sick could help the enemy.

That's where Spain highlighted. Since it was a neutral country, it had no need to keep secrets when its people got sick, so the Spanish government and media reported what was happening. 

(4)No one actually knows where the virus started. For decades, scientists have debated where in the world the pandemic started, variously pinpointing its origins in France, China, the American Midwest, and beyond. The Spanish flu reached its height in autumn 1918 but raged until 1920.

(5)People who catched the flu felt severe fatigue, fever, and headaches. Many also suffered from a cough so severe they would turn blue, tear abdominal muscles from coughing, and bleed from the mouth, nose, and sometimes ears.

The disease, which came to be known as the Spanish flu, hit the young and healthy, with many victims dying within hours or a couple days after the symptoms began.

compilation-of-best-screenshots-during-video-conference-calls

The coronavirus pandemic is creating big troubles for people. Work and studies from home are the new conditions for everyone all across the globe. To prevent the virus from spreading at the workplace, schools and universities, more and more companies are turning to remote work as a necessary step to continue realizing their agenda. This unpredicted new reality is for an unknown time limits, but it made the bosses meet their employees online.


One of the leaders decisions, is to encourage people to work from home during quarantine. Working from home for someone is paradise, but for others can be horrible. Families with children found here a big problem, no video conference without them. There are also some people who have problems with modern technology, so they transform themselves in a potato, using some filters and are unable to figure out how to turn the filter off.

The global work-from-home movement intended to maintain efficiency during the COVID-19 pandemic, so people can maintain economic stability in their family budget. The closure of schools and transition to “distance learning” for children, created the condition of studying at home, so students now are the one who also have daily online conferences.

For many persons, setting up a home office is a full creation, while in self-isolation people get creative. Some parents share their desk space with kids or are having furry little friends participate in conference calls. No matter in which situation you are, you have to work or study at home. Online conferences are the best option, while learning and working process is maintained.
