Covid-19 in Melbourne [Australia] and Viral Load

For those in other parts of the world, my city, Melbourne, is in the middle of a Covid-19 resurgence, and we’re being locked down again.

Much has been made about the so-called ‘error of judgement’ that led to a private security company being tasked with keeping travellers in hotel quarantine. The truth, however is a lot more complicated:

  • yes, the security guards assigned to the hotels were not properly ‘educated’ about the virus,
  • and yes, some of those security guards caught the virus themselves,
  • and yes, the infected guards did bring the virus home to their friends and family,
  • but…they would not have been able to infect as many friends and family if Scott Morrison, Prime Minister of Australia and leader of the Liberal National Party had not pushed so hard for Victoria to reopen.

Part of the re-opening in Victoria included the ability to visit more people outside of our immediate families. This led to big family get togethers, especially in migrant families for whom family connections are not only strong but vital.

Now think – what would a family get together be without kisses and hugs?

‘The government said it’s okay to get together so it must be safe. And if it’s safe, why should we not kiss and hug?’

One of the reasons why social distancing is so important could well be viral load.

No idea what that is?

I was struggling with the concept myself until I watched Dr John Campbell’s video this morning:

There is some technical stuff in the video, but Dr John is very good at explaining complex ideas in simple ways so please don’t skip this one.

For those who only want the bottom line, it’s this:

  1. a small viral load – i.e. about 10 viral particles – will likely get caught in the mucus membranes of the nose and throat, giving your immune system TIME to mount a counter attack. By the time the virus has spread enough to reach the lungs, the body is already fighting back. This could explain why some disease is less deadly.
  2. a large viral load – i.e. about 100 viral particles – goes straight to the lungs. Once in the lungs, it begins causing pneumonia before the immune system has had a chance to fight back. The lungs are a perfect place for the virus to reproduce and spread, so it does. This could explain why lung infections can be so deadly.

The mechanism determining whether we get a mild infection or a severe one is much more complicated that just viral load, but understanding the impact of viral load can make a difference in how we behave.

If I walk down the street, wearing a mask, and I pass you, also wearing a mask, the chance of being infected with a large viral load is almost zero.

But if you and I are in a crowded bus, and neither of us is wearing a mask, the chance of breathing in a lot of viral particles goes way up.

And finally, if we are friends and we kiss and hug when we meet, the chance of becoming infected or passing on the infection sky rockets. Why? Because the pathways for the virus include:

  • breath to breath
  • contact to contact, via saliva
  • hand to hand and then from hand to mouth/nose/eyes
  • passive droplets in the air
  • passive droplets on surfaces
  • passive droplets on uncooked food such as salads, or cooked foods that may have been touched by hand [after cooking], or breathed on accidentally [after cooking]
  • passive droplets on plates, cutlery, towels, toys

I could go on and on, but I think you can see where this is going. The more contact, the greater the likelihood of severe infection. So yes, in hindsight, a private security company obviously wasn’t the right choice. But who would have been? The police? What makes us think the police or the ADF [Australian Defence Force] would have been better educated about pandemic protocols?

And finally, let’s not forget the bloody great elephant in the room: the reopening. If people had not been allowed to visit each other, the virus could not have spread from the security guards in the first place. Or if it had, the clusters would have been small and manageable.

It takes two to tango, and Victoria’s dance partners included:

  • Scott Morrison and henchmen like Dan Tehan, the Federal Education Minister who castigated my Premier for being too cautious and not opening up the schools faster.
  • And let’s not forget Michael O’Brien. Michael who? Michael O’Brien, the leader of the LNP here in Victoria. Yes, the man in the same party as Scott Morrison et al. The man so desperate to gain political advantage that he made attack ads against my Premier, telling Victorians that they were missing out, being left behind, doing it tough because we weren’t opening up fast enough.
  • Smarmy Tim Wilson should probably rate a mention as well. Yet another LNP politician in Victoria looking to cash in on Covid-19.

I’m sure there are more, but I can only handle so much anger in one day so I’m not going to go online to research who else played a part in what’s happening to my city and my state. For me, the bottom line is that my Premier, Dan Andrews, has fought long and hard to keep people alive. Those other politicians I named care only about one thing – the economy.

I ask you to remember those names when Covid-19 stops being an inconvenience and starts hurting the people you love.

    Little islands of sanity in an increasingly fucked-up ocean of stupidity and greed … that’s what it’s come to, I think, and we need to defend those islands for all our sakes. Once the ocean recedes then can we engage with the wider world again.

    Hear, hear! The absolute stupidity of people who refuse to wear masks, wash their hands, and distance themselves is appalling. So simple, yet apparently a bridge too far for many. SMH. The only good news is that more folks here in the US are actually figuring out the Rs and the twit in the WH are crapping all over those who would vote for them. Reopen schools? Are they delusional?

      Hi DV. Things we used to take as common sense have been politicized until black is white and white is black. The same is happening here, although to a lesser degree. I know things will change, eventually, but just at the moment the madness feels never ending.
      Stay well. -hugs-

    All I can say is this… take this thing seriously folks! I live in NYC which was for a few months the epicenter in the U.S. and is now, way, way down. The State and City governments worked the NUMBERS and the SCIENCE, restricting activity and loosening the restrictions only when the stats indicated it was OK. For example, this week in NYC we were supposed to allow a little indoor dining. There was a small uptick in the cases last week so there’s a delay in indoor dining. As it is high summer here, and the City is adaptable, we’re dining outside. So much so that I’m starting to think of the avenue on my corner as an extended buffet. in the meantime, other locations in the U.S. are determined to avoid restrictions on their activities. It’s as if NY never happened!!! They won’t or can’t learn from what we did (and what European countries did) and slowly open only after the lockdown has had a real impact. I’m astonished at what’s happening in Florida and Texas in particular. Wear masks. Wash your hands. Limit your activities.

    Right now, I’m hurting. I live alone and have very limited in-person interactions. I don’t live with family or a partner. So… I am lonely! I’m dealing with it. Slowly, slowly… I’m starting to get together with people in socially “distant” social settings, like the roof of my building, outdoor dining, etc. This is NOT the way I choose to live, but I want to avoid a repeat of this past spring so… I’m doing it.

    When I see people refusing to wear masks on the grounds of civil liberties I want to scream. Mask up! Wash up! And one day I’ll dance Tango again and we’ll all do the things we love and be out and about in crowds. JUST NOT NOW!

      -huge hug- Thank you, Candy. People, my people, your people, need to hear this. And we need to change our expectations. Sacrifice now so we can all live and enjoy life later.

      I really appreciate your honesty, and I’m so glad you’re starting to have some social interactions, even if they’re distant. Take care and stay strong.


  • A Melbourne-wide lockdown – Anne Lawson Art

    […] has copped a lot of flack because of the spread from hotel quarantine to security personnel. My friend Meeks points out that others, including the federal Liberal Government, had a big role to play in the outbreak […]


  • CarolCooks2

    Hurrah for WA cos they ain’t letting the other side in and neither are we…We are also still having to wear masks in public places, observe social distancing and have our temps checked and scan in if you have the app if not you sign in and out and give your details…No one argues they are just pleased we have zero cases for 40 days.Sorry to brag but it works and the kids in school have to wear full face masks…Now going to wash my hands…be well and stay safe Meeks x

      -hugs- You’re a champ, Carol. And for those who don’t know, Carol is living in Thailand. Everything she’s mentioned we could do too. It’s not rocket science. All it takes is a little bit of social responsibility and some common sense.

    Good on you for calling out the Liberals and their push to open up quickly. And Michael O’Brien carping on about how Andrews should have called in the army. No partisan politics there. I smiled when Andrews said at today’s press conference that he has much better and more important things to do than pay the political game that the Liberals are trying to get him to play. Because things are very serious, and the Liberal opposition just doesn’t get it. I also got fleetingly cross when O’Brien said he felt for the people in the northern suburbs. When has he ever cared about us before?! Grrr.

      lmao! I’m so glad I’m not the only one who’s noticed what that little creep has been doing. O’Brien, not Andrews!!
      Did you watch the 7.30 interview with Dan Andrews tonight? Trioli was trying to trip him up so badly. Instead we saw what courage under fire looks like. Still glad I live in Victoria. 🙂

      It was almost inevitable, Robbie. Not to big note, but I’ve been stockpiling toilet paper for weeks. I truly believe the Federal govt here has been putting the cart before the horse all along. Now we’re paying for it.
      How’s it going in South Africa? I haven’t seen anything for a while.

        As expected, C-19 is going mad here, Meeks. We have 215 000 infection compared to Australia which is not yet 9 000. We have had 3 500 deaths compared to your 106 deaths and we had 198 deaths yesterday. Our C-19 cases have doubled in the past 2 weeks. It is very sad as our people are very vulnerable. Government has really tried but you can’t really lock down our poor as I’ve mentioned before. It is impossible to self isolate when you live in a tin shack. I am providing food to 2 African families each month and we are supporting other funding initiatives through work and our church. We can’t do much more and it is very frustrating.

    Didn’t know the number you can tolerate of virus particles is so low! Ten? Wow.

      Yes, that was an eye opener for me too. I have no idea whether that’s an actual number of simply an illustration of small vs big. But it does make sense of the whole viral load thing, and why health care workers are more likely to get the virus despite the PPE.


      • Alicia Butcher Ehrhardt

        I had read before, and stowed away in the dim recesses of my mind, that we could handle 1000 virus particles, but that larger loads overwhelmed the system.

        It doesn’t matter – either you get too few, or you get sick. I’m wearing masks in public, and washing my hands, etc., so that whatever is out there, and I pick up, does not get transferred into my body via eyes, nose, or mouth!

        Washing with soap for twenty seconds DEFINITELY kills all of it. I can’t believe that a quick rub with a tiny squirt of hand sanitizer is equivalent. I almost never use it.
