Covid......... easy to protect yourself.

[IT Minion]

False equivalence

Not at all, all are protective measures, all complement each other. All are useful and the presence of one doesn't mean you shouldn't do the other.

(although if we're being pedantic I'm not sure how useful airbags and seatbelts are at preventing Covid-19 transmission nor the effect of washing hands on car crashes)

I read last night that they *think* transmission by touching covid contaminated surfaces things amounts to about 10%. The rest is airborne. How the heck they can figure that out though..?

Possibly by contact tracing?

When groups of people in air-conditioned offices are infected when they sit under an air-outlet circulating air from an area where an infected person sits; but people at the other end of the office, under a different air circulator, are not infected, although they use the same lift-buttons, door-handles and toilets; and where people sharing a kitchen, or handling glasses in an outdoor bar, are not infected, would give the real-life clues.

Respiratory infections which are exhaled by one person, and inhaled by another, passing from the first respiratory tract to the second, are very successful.

no doubt we will know more as time progresses

I think this is the "office" story

https://wwwnc.cdc.gov/eid/article/26/8/20-1274_article

"However, if we restrict our results the 11th floor, the attack rate was as high as 43.5%. This outbreak shows alarmingly that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can be exceptionally contagious in crowded office settings such as a call center. The magnitude of the outbreak illustrates how a high-density work environment can become a high-risk site for the spread of COVID-19 and potentially a source of further transmission. Nearly all the case-patients were on one side of the building on 11th floor."

I think heating the water, growing yeasts in it, and storing it in sealed containers may also have helped. Viruses can only propagate inside living cells.

A useful travellers' tip is to drink water from the hot tap in hotels, because it will have been heated, and stored at an elevated temperature, which pasteurises it.

The hot water supply might be safer than the cold in some parts of the world, but there is no way I would normally advise using using stored hot water as drinking water. One word - Legionella!

 

[JohnD]

yes, I thought that might be mentioned.

Do you think it is caught by inhaling aerosol droplets? Or by drinking water?

If hot water is stored in a cylinder, does the virus propagate? How long does it take to die?


(hint: I know the answers)

update - bacillus, not virus, thanks EddieM

My understanding is, that Legionella is killed by temperatures over 60C, but can propagate in any stored water or water which is in a dead leg of pipework. So, if there are any less frequently used sections of pipework, or unused sections following modifications, they should be flushed regularly or dead legs removed.

Correct, but you don't get Legionnaire's from drinking contaminated water; you get it from breathing the aerosol / droplets.

 

[EddieM]

Legionnaires disease is caused by the legionnaires bacillus As stated viruses cannot replicate by themselves as they lack DNA, having RNA instead.

First lockdown was a complete failure.
Now heading into another one which will also be a complete failure.

The graphs from the first lockdown, the hospitalisations and deaths, would suggest it was an over whelming success.

covid is still here. As strong as ever.
The graphs are nonsense. Cooked up by a government in panic.

They rolled them out yesterday for nothing more than a scaremongering exercise.
The scamdemic rolls on.

You are (and you know it) spouting absolute nonsense.

You are a believer in wild conspirancy theories and I claim my five pounds.

"Last week the signs were growing that this dictatorship of stupidity may at last be coming to an end.
Distinguished scientists from around the world are demanding sanity. Even our pathetic MP's are beginning to wonder if they have been had.

The media are slowly waking up to their proper duty of questioning authority.
The fact most people who get covid 19 are just fine is starting to sink in.
The mad shut down measures are visibly not working."
