More info on Covid-19

My thanks to Don Charisma for posting the latest Dr John Campbell health video on his blog.

For those who haven’t yet heard of Dr John, he’s a retired UK nurse/teacher/researcher who is analysing the latest data about this virus and explaining it to us. He has a Youtube channel, and this is his latest video:

I strongly recommend watching the entire video because it is full of information relevant to different countries, but here are the bits of particular interest to me.

Confined spaces and aircon

There was some meticulous research done [in China] on the spread of infection in a bus. I don’t know what it is about the air conditioning in the bus, but it basically doubled the radius of infection to 4.5 metres. In simple terms, the virus from an infected passenger travelled much further than previously thought.

Note: the radius of infection is basically how far droplets containing virus will spread in the air before falling to the ground.

Virus survival on surfaces

Another thing that worried me is the information about how long the virus survives on surfaces such as metal, cloth, paper etc. It can survive – on surfaces – at 37C for days. That’s roughly 10C more than previously thought. That means this virus is hardier than we imagined. It also means that every infected person has the potential to infect people he or she is never in physical contact with.

Think about all the shopping trolley handles we touch, how many counters in shops, how many door knobs, tables, chairs… The list is endless, which means we have to be super vigilant, not just to protect ourselves, but to protect those we love. Do NOT soldier on, you could kill someone.

Government intervention

And finally, a word about government intervention. The countries that have been proactive about stopping the spread of Covid-19 are doing better than those which have not. We need to learn what works and do it in our own countries.

One thing which has worked particularly well in South Korea is ‘drive through testing’. You stay safe inside your car – your own little bubble of protection – and drive away without having to come in physical contact with others who may or may not be infected.

When I saw news footage of people waiting in long queues [here] to be tested, my first thought was, “well, if they didn’t have it before, they may well have it now”. Gatherings of people who may already be infected is such a bad idea…

Melbourne [Australia]

Daniel Andrews [Premier of my state of Victoria] has declared that his government is going to take more stringent measures against the spread of Covid-19. I’m glad, but I still think that allowing Moomba and the Grand Prix to go ahead in Melbourne was a bad idea.

I understand that we do not yet have the level of community spread that triggers more ‘stringent’ measures, but we also don’t have the community awareness required to take this threat seriously. Traditional, normal public gatherings like these simply reinforce the idea that we’re ‘safe’.

We’re not safe, and we have to get used to that idea. We have to get used to taking precautions such as wearing masks and gloves, washing our hands religiously, staying away from crowds and air conditioned centres. We have to start doing these things now so that when things do get worse, they’ll get worse at a slower rate.

Northern Italy

I cannot stress enough how important it is to slow the spread of this virus.

The following is a screenshot of a thread I read on Twitter last night. It’s from Northern Italy and describes a health care system teetering on the brink of collapse. Yet Northern Italy has a world class health system.

We have world class hospitals in Australia too, but people with the pneumonia stage of the infection need ventilators. These machines are capable of breathing for the patient until they are capable of breathing on their own again. But if everyone gets sick at once, how many are going to miss out on ventilators because there aren’t enough to go around? How many will die?

Deaths by age

Going back to the Dr John video, the stats showing the break down of deaths by age show that small children appear to be remarkably resilient:

From the age of 10 onwards, however, young people do die from Covid-19 as well. 0.2% of deaths amongst young people may not sound like much, but they are still people, real people.

Do you really want your ‘she’ll be right’ attitude to result in the death of your brother, sister, best friend, lover, wife, husband?

Or what about your parents? Aunts? Uncles? Grandparents?

We have to slow the spread of this virus, and we have to start now.

    Perhaps now that it’s been ‘officially’ declared a pandemic people and governments will start to be a little more proactive. I don’t have high hopes for it being timely though, inertia being what it is in bureaucrat-land.


    • acflory

      Yes, you’re right, inertia is going to be the greatest danger. This is where elected officials in govt could really make a difference. If. I fear they’re not learning the lessons from Italy, or still motivated by outdated ideologies…like let’s have a surplus no matter what…

    I so wish more people would take this seriously.

    We canceled our family vacation and wills tay home and hike instead. I know it was a hard choice, but losing my kids or spouse is harder. Or knowing we contracted and it gave it to someone else who didn’t make it.


    • acflory

      -hugs- It is a hard choice, but I truly believe it’s the only ethical one. It may also be the only sure way to protect our loved ones. I believe the US is starting to ramp up its response to Covid-19. Fingers crossed it’s fast enough to stop the spread of this damn virus.

    That’s interesting about the length of time the virus will live on surfaces. Last I heard, they weren’t;t sure of the answer to that. Which is part of the problem we all have….that this virus is so new and so much about it is unknown.
    As for the Grand Prix, i think this would be a good time to cancel it altogether! That’s me going back to the Save Albert Park days, with Corvid-19 thrown in!


    • acflory

      Yes, this virus is so new, a lot of this information is only coming out in dribs and drabs as researchers scramble to understand it.

      I’ve never been to the Grand Prix or watched it on tv so I’d be happy to have it cancelled as well, especially now. πŸ˜€


  • Candy Korman

    Hand washing. No hugging friends hello & goodbye. Not dancing Tango. No hand shaking. Washing hands washing hands washing hands….


    • acflory

      Yup…that’s about it. Oh, but you could try the elbow bump and foot tap. πŸ™‚ Not sure where it started but I saw a video of guys tapping each other’s /feet/ instead of shaking hands. It actually looked like fun. πŸ™‚



    Without being alarmist I’m pretty sure there’s more to #covid19 than meets the media eye… the stats are only coming from cases that have been tracked and tested positive. The number of infected people voluntarily self-isolating could be quite different and there’s still a chance they might have been contagious and in contact before self-isolating. Just like other flu viruses, so easily spread. Early days yet.


    • acflory

      Not being alarmist at all, Dale. That’s why we’ve self-isolated already. I wear a mask when I /have/ to go shopping and while I’m getting contemptuous looks, I’ve stopped caring. By the time the authorities officially declare Covid-19 as loose in the community, it could already be too late for vulnerable people.

      Btw, remember that little plastic greenhouse thing I bought a couple of years ago? I set it up again two days ago and I’m growing lettuce in it, in plastic cups [with holes drilled through the bottom]. I’ve also planted basil, peas, leeks, spring onions and some herbs. If even some of them thrive, we’ll have salad type stuff that hasn’t been touched by anyone else.
      Two days ago I still felt a little paranoid. Today? I’m thinking planting more.

    Really good video. Thank you for sharing it.
    I read today that several pregnant women with Covid-19 gave birth to children who did not test positive for the virus. Wonderful news and very interesting.
    My youngest daughter lives in the USA. After coming back from a trip to Las Vegas, Nevada she fell ill with the symptoms of Covid-19. The doctor would not test her (she has good healthcare insurance through her work). She was told that she’d only be tested if she were very ill and in the ER.
    To her credit, she self-isolated and worked from home.


    • acflory

      OMG…that’s awful, Ellen. Is your daughter okay? I’m sure she’ll sail through it, but you must be so worried.
      On a more general level, I know Las Vegas is a crowded place with lots of out of town visitors, but for your daughter to catch Covid-19 /there/ is a frightening indicator of how the virus will spread as people return home to other states.
      Please keep us updated on your daughter’s progress. And please stay healthy yourself.
