Tuberculosis vaccine, BCG seems to correlate well with lower rates of infection and lower mortality. Many immigrants to the US may have had a BCG vaccine at birth or childhood. Countries like the US, Italy, Belgium, Netherlands have never required universal BCG vaccine, and those countries have had some of the highest rates of infections and mortality.
Just look at some country pairs that are close demographically and geographically but different on BCG status, like Ireland-UK, Portugal-Spain, Norway-Sweden, and the results are quite intriguing. The first country in each of the 3 pairs has universal BCG vaccine, while the 2nd country in the 3 pairs does not. In each pairing the mortality rates are multiples lower.

Yes. I've had a BCG vaccine at birth or childhood. Not sure how long immunity lasts and the neg. has been chest xray requirements vs PPD skin tests. I hope this correlation is clinically significant

On a side note I've wondered why they don't vaccinate everyone here in US. Parts of US have had TB outbreaks
Pledge makes an antibacterial all surface spray that I spray into a microfiber and wipe the screen but I have a screen protector on it. Also I can’t speak as to if it’s effective against the virus, I’ve been using it since before the pandemic.

Will Clorox wipes, with bleach, damage black seats? I wiped mine down after picking my niece up from the airport last week, then freaked out and wiped them all again with just a wet rang because I was afraid the bleach would stain the seats.

As a microbiologist, we have the saying, "If it dries, it dies." Bacteria and viruses die when they dry.
Of course, if one were to spit a glob of sputum onto your dashboard, the various viruses would live for a while. Until they dry.
Also, if someone sprays you with droplets and you lick them off, there is a chance you will get infected, assuming they are a carrier, but that's why they want you to wash your hands. If you breathe in just after someone sneezes in your face, well, you'll likely get infected. That's what masks are about, but anyone keeping 6' distance will be unlikely to get moist spray on them. Even then, not everyone who gets infected gets sick. That's why the 6' rule. If it dries, it dies.
All this silliness about wiping down your car, your MCU, your door knobs, etc, is pretty much useless, unless you just need to feel good about yourselves.

Supposedly it works for ~20yrs, against TB, but the idea is that it revs up the immune system so that it's better at combating Covid-19. Harvard Med and Mass General are doing a 4000 person study, so we'll find out in a few months. I hope they test different strains of BCG, because the Japanese/Russian/Brazil version is an older strain and seems to be particularly promising. The Denmark strain seems to be not as effective. The countries I listed are countries of manufacture, but are used widely by other countries. Most european countries use the Denmark strain, that sort of thing. My birth country used the Japanese-made strain.
Interesting. But I don’t think I was being paranoid when I posted this, long before the UK and the world went into lockdown. After all, the BBC still reports that the virus may live on hard surfaces for several days: Covid-19: How long does the coronavirus last on surfaces?
That’s the BBC, not Fox News. Arguably the most reliable and impartial news source in the world?
But I take your point that we may all be taking this disinfecting stuff a bit too far. Thank you. It’s a bit moot now anyway given that I can’t really drive anywhere these days!
5 years ago is a long time ago.
At my work we have to do safety training modules every year.
According to the map I have, India uses multiple BCG strains, so you can't tell. Of course, the map is only for 2003 to 2007, but gives some idea. There are country pages, at: BCG Wold Atlas
hoping multiple BCG strains= cocktail? I got mine in the 70s

Banana emits radiation.

Inside banana shipments to hide the radiation signal.
let’s ban banana!! Lol
For real, google it up.

Yeah they also have done a complete shutdown, that's being enforced a la China style.
You're right about testing though. Once it get's into the slums all bets are off: Inside the race to halt the virus in a vast Indian slum
