One of the things that I don't think we are doing a good job of here in Canada is promoting our COVID Alert app. Most of the people I talk to don't seem to have it installed on their phones. And most of the people I talk to seem to be nervous about sharing personal information with it, including their location. (That's not actually how the app works.)

The thing with exposure alert apps is that they're only really useful if most people are using them. And they're only really useful if people who test positive for the virus enter the code that they are given into the app. So it relies on us trusting that other people will do the right thing. I get that. But those same shortcomings apply when we just ask someone if they've been exposed to anyone with COVID-19.

I could be wrong, but my view on this is pretty simple.

If everyone who had COVID-19 got immediately sick and showed highly discernible symptoms, then this virus would likely be a lot easier to control. Part of the problem, as I understand it, is that some people get really sick and some people don't get sick at all. But these latter people can still unknowingly spread it around -- perhaps to other people who might get really sick.

Given this variability, it's critical for us to know who has been potentially exposed and who has not been exposed. Otherwise, we're running around mostly blind. From what I can tell, exposure alert apps are one of the best ways for us to track transmission. But, of course, it only works if you've got the app. For those of you who don't already have it, you can download it for both iOS and Android by going here.

P.S. I'm writing this post because it came up with my barber today while I was getting a haircut. He wasn't all that aware of the app, but he ultimately concluded that we have a problem of education and that he was going to download it. Maybe some of you will do the same after reading this.

Back in March, I was reading everything I could find about COVID-19 and about pandemics. Eventually that tapered off. But this week I decided that it was time to go back and learn a lot more about the 1918 Spanish Flu.

I've just ordered John M. Barry's 2004 book called The Great Influenza. Bill Gates wrote about it over the summer -- after he reread it -- and said that it will teach you almost everything you need to know about the influenza. He also said that it's never been more relevant.

Despite happening over 100 years ago, there are no doubt lessons that we can learn from this great influenza. The most important being that leadership and honesty, of course, matter a great deal during a time of crisis.

Barry also argues that the 1918 influenza was responsible for altering the flow of history. He makes the claim (convincingly according to Bill) that it was a contributing factor in the rise of Hitler and the start of World War II.

So I'm looking forward to receiving my copy later this week. If you'd like to purchase your own, you can do that over here. And if you've already read it, please let me know what you thought in the comment section below.

Seeing people out at bars and at amusements parks in this WSJ video about Wuhan, China is a little odd given that in this part of the world we are decisively in our second wave. But that is what is happening. In fact, the title of the video is, "Wuhan, Former Pandemic Center, Emerges as Tourist Hot Spot."

Over a recent public holiday, the city saw nearly 19 million tourists -- the most of any Chinese city. And while tourist revenues are still thought to be down by some 30%, Chinese people are seemingly feeling confident enough to get back out and do things.

Based on what the WSJ is reporting, this seems to be supported by a few things. International travel isn't happening, so it's becoming a boon for local tourism, which is not that dissimilar from what's happening in other countries. (Domestic air travel is rebounding faster than international travel when you look at flight volumes across major airlines.)

At the same time, Wuhan implemented what sounds like some pretty extensive testing, which is in turn supported by a national healthcare platform that presumably makes contact tracing easier. These things seem to have given people the confidence to go out again. And I don't doubt that the same will eventually happen in the rest of the world.
