Those links don’t help me understand much.
Wikipedia’s https://en.wikipedia.org/wiki/Flutrack seems different, it’s an analysis of twitter searching for words like “influenza”.
In fact, the only reference to it in wikipedia seems to be a single sentence in https://en.wikipedia.org/wiki/Influenzanet
“Influenzanet is a syndromic surveillance system that monitors the activity of influenza-like illness (ILI) with the help of volunteers via the Internet. … In Australia, a comparable project called Flutracking started in 2006 with 400 Flutrackers completing a 10 – 15 second online survey about flu-like symptoms each week has over 8,000 weekly participants in 2010.”
Aha, here’s the link you want to read:

2018 was a low flu incidence year in Australia, fairly constant at up to 1.8%. But that’s still a lot higher than Holland, Belgium, Portugal in 2008-2009, which peaked at 1.2% and went as low as 0.1% (even less in Belgium). Most who sought medical help for fever and cough in Australia in 2018 did not have the flu, only 4.3% did. mollwollfumble guesses that most of the rest had colds, 2018 was a bad year for colds.

I find cold temperatures can give me a runny nose.
ie under 15 degrees, this temp would be slightly different for different people
I’m wondering if there is a way to keep colds and flu at bay using warm air ?
Use people who regularly get colds each year
Create a study into people who wear face marks designed to keep the temperatures of the nose at warmer temperatures
maybe they will only have to wear face masks for only a few months of the year while in colder environments
I’m thinking face marks that can create a temperature of around 20 degrees.
The face masks could be designed to be transparent and light and just covering the nose area.
