I’m sure your mother heard that information. And I wouldn’t be surprised if she heard it from someone at a hospital, maybe even a nurse.
And I understand that we’re all looking for more information. Many of us want to know what we can do, and want to know more about the virus and how to protect ourselves.
So when someone hears that the virus ‘dies at over 77 degrees due to it having a thin layer of fat keeping it alive’, that sounds like really good news.
But, it’s not true. If it were true, then the virus would be rendered inactive the moment it entered a human body. And bats have body temperatures of as much as 105° when they fly, so how would the virus thrive in them if this were true?
Maybe the whole ‘melt the fat’ idea came from what we know about how
soap affects the virus. I don’t know.
But if what your mother is thinking is that turning up the thermostat will kill the virus, that’s a bad idea - in most circumstances, it will only make the virus able to remain active longer.
And the last thing we need is people turning up their houses to over 70° to ‘kill’ the virus because of a rumor they heard on the internet. With all the desperation so many people have to ‘find something to do about it’, or to try to get control over our lives with everything that is going on, false or even harmful information like that - information that is easily demonstratively wrong - can really hurt others.
The truth is that human coronaviruses really enjoys 70° and can survive on exposed surfaces at 70°
for up to a month ( albeit most of the variants of it have a half life of under a few hours
depending on other conditions ). And the new human coronavirus has been observed to remain viable for
three days on stainless steel in those or similar conditions, and for as long as
17 days in examples like some of the cruise ships.
In fact, if you turn the temperature up even higher, it remains viable even longer, and you have to go up to 86° before you really start to shorten it’s life on most surfaces and 104° before you can get it to behave more like a flu virus.
So turning up your thermostats is not going to help.
What WILL help is disinfectants with 62-71% ethanol, or 0.5% hydrogen peroxide, or 0.1% sodium hypochlorite (bleach). Spraying or wiping surfaces with these can inactivate coronaviruses within a minute.
The
CDC has a ‘how to disinfect’ worksheet that you might also find very handy.
Part of the problem with all of this is that the virus is not ‘technically speaking’, alive. It’s just a self-replicating molecule that is really good at rewriting the DNA of cells with it’s tiny strand of RNA.
It’s hard to ‘kill’ something that isn’t really ‘alive’ to start with.
