Covid 19 should be no new cases?

[silverfoxcc]

Did i dream it, or when this was first rampant, there was an article that said it could not survive over 25C or thereabouts

With this heatwave at the moment,why are there new cases..or was the original article a lot of 'Bo Lax' ?

Probably a load of cobblers as per: drinking hot liquids / alcohol / dettox kills it..


..not everyone works in 25C+ temperatures though (even if it was true).. hence the out breaks at meat packaging plants: Cold + People need to get closer in order to communicate over the noise from refrigerators.. etc etc..

Survival time varies with temperature. Hotter= shorter.
No idea what shape the relationship curve is. Linear/non-linear/exponential or whatever.

Well it seems to survive in the human body at a temperature of 35.8 ok so it probably is cobblers.

Human body temperature is 36-37'C (airways a few degrees cooler) so if the virus couldn't survive at 25'C+ we would all be immune to it.

It would probably be able to survive a few degrees more than human body temperature.

However, it won't like prolonged exposure to UV light and any virus outside the body will start to lose viability, some faster than others.
Although I don't have specific figures, perhaps at 20'C you would find 1% of viruses 'die' each minute outside the body while at 25'C it's 2% dying each minute, up to about 50'C where probably all the viruses would die within a minute.

Some types of viruses are quite tough and even at 25'C half of them might still be viable a month after being ejected from someone's body. Others are quite fragile.

I recall the article too, but like silverfoxcc said it was about the length it can survive without a host. The hotter it gets the quicker it dies

I did some googling a while back on this and at 56 degrees it reduces fairly rapidly but it needs 92 degrees or higher to actually kill it off completely, even then its not instant.

I think the thing to bear in mind is that if the hot weather did it for CV-19 then you wouldn't have flare ups in hot countries or regions, all of which, we do! The real concern is the cold weather, as has been shown by the meat packing plants, it thrives in those kind of temps, winter could be tough, plus side of these kind of conditions, people tend to stay home more when the weather is god awful, we'll see I guess.

Anyone have a crystal ball handy?
