Study shows that Covid-19 can survive high temperatures

Virus 'dies faster in direct sunlight'

William Bryan, the under secretary for science and technology at the US Department of Homeland Security, says the coronavirus may be killed faster under increased temperature, humidity and sunlight.

"We identified that heat and humidity is a weakness" of the virus' ability to spread, Bryan says, showing data suggesting that the virus could survive for 90 seconds under direct sunlight, and for 90 minutes without any solar contact.

The findings are an "emerging" result of their work, Bryan says.

I think there is a difference between surviving and propagating, the virus survived but only resumed when conditions improved. 

The virus was placed in kidneys "donated" by African Green monkeys.  The virus continued replicating while subjected to 60 degrees celsius heat for an hour. It was only killed off by 100 degree heat.

Would also be interesting to see two similar sets of samples.

One left in direct sunligt and one left in the shade.

 

Just to see if the natural UV does something or not.

There's no argument about this. It's been proven clearly in both covid-19, and for decades past in relation to older viruses. It's extremely easy to provide scientific verification of how long the virus lasts on various types of outdoor surfaces in different conditions, and it's baffling that people are even debating about it.

 

The far more complicated question to answer is what happens to the virus inside someone's body in a tropical climate. Is the version that people catch weakened in dose by the heat and humidity? Why are so much fewer people in the tropics dying of it? Do people in these regions have better natural immunity, or fight off viral infections more easily in the hot humid weather? Is it connected with the long established phenomenon that people's immune systems are weaker and more susceptible in the cold winter months? 

 

There have been zero examples of runaway covid-19 rates in any tropical country (ie. escalating in a few weeks from low case numbers to tallies in the six figures (and numbers of deaths in five figures). The US, Italy, Spain, France and the UK all have these high infection and death rates and all have comparable climates. In South East Asia where the first reported cases predated those in Europe and the US, why are the death rates so low? We're not talking half or a third here, but <0.1 - 0.5% of the death rates in the Western countries listed above. 

 

It seems obvious that people are asking the wrong questions in this debate. Two months ago it was a valid thing to ask - will the virus recede and die out in the summer months? But now it's a completely different question - why has the virus had only minimal effects on populations of hot tropical countries compared to the worst affected countries in the west (and initially North East Asia)? Two months ago this was speculation, but now it's backed up by numbers, particularly of death rates which can't be easily covered up. Why has India with it's 1.35 billion people and terrible conditions of overcrowding and lack of sanitation only had 700+ deaths? Why has Malaysia that had a huge cluster of infections in late February at a religious gathering still only recorded less than 100 deaths? Why have Thailand's widely reported clusters in late February and early March not amounted to anything? We really need to be asking better questions.

No one believes that lying idiot a-hole except uneducated racist rednecks

We differ in opinions! people that make remarks like you have tend to be uneducated persons who are unable to think for themselves from what I am seeing, they are unable to accept that there is another POV besides there own - whatever - have a nice day ????

I think this is way too complicated to understand without a year or more of testing. 

 

Imagine just for example you wanted to test what ants can survive. So you drop a brick on them. Oh, wow, they "survived".... mangled and crippled. 

 

Viruses are not even "alive" anyway. 

 

I would not give two ounces of credit to this either way. Be cautious but I just think we need to admit we do not know yet.

AS you say and I have said here before , you cannot dismiss the facts that Thailand and its SEA neighbours have up to now been the least effected countries . That alone merits a global study . Why is it that the winter months bring colds and flu ? it is a fact that peoples immunity levels drop in colder climates as the levels of vitamin D drop because of the lack of exposure to the sun .
In the UK the NHS has suffered great losses of coloured doctors , nurses and others involved at the front line at a disproportionate rate compared with white medics . Reason being low vitamin D / immunity as their skin colour is to protect them from the much stronger sun from their countries of origin . 
The WHO need major support , not criticism but an inquiry into the whole virus event as there are lessons to be learnt . The UKs SAGE also need to be investigated over the initial advice given to B.Johnson 
Big questions , will we ever be rid of this virus ?   where did it come from ?  is there a threat that this could happen again from a different virus ?  Is germ warfare being researched by secretive countries ?
One thing is for sure and that is the virus has disrupted life as we knew it and also for the future . It may well be that wearing masks will become mandatory as at the moment the voluntary  practice is common in some Asian countries
