This guy is a 25 year expert on the subject of Corona Viruses and how they spread.
"Three things the virus does not like: 1. Sunlight, 2. Temperature, and 3. Humidity," Nicholls said in response to a question about when he thinks confirmed cases will peak.
"Sunlight will cut the virus' ability to grow in half so the half-life will be 2.5 minutes and in the dark it's about 13 to 20 [minutes]," Nicholls said. "Sunlight is really good at killing viruses."
For that reason, he also added that he doesn't expect areas such as Australia, Africa and the Southern hemisphere to see high rates of infection because they are in the middle of summer.
Regarding temperatures, Nicholls said the warmer the better for stopping the spread of the virus, according to the transcript of the conference call.
"The virus can remain intact at 4 degrees (39 degrees Fahrenheit) or 10 degrees (50 F) for a longer period of time," Nicholls said, referring to Celsius measurements, according to the transcript. "But at 30 degrees (86 degrees F) then you get inactivation. And high humidity -- the virus doesn't like it either," he added, the transcript of the call showed.
At the University of Hong Kong, Nicholls has spent the past 25 years studying coronavirus and he served as a key member of the team that characterized SARS. The Hong Kong University Faculty of Medicine's Clinical Research Centre also created the world's first lab-grown copy of novel coronavirus, according to CNN correspondent Kristie Lu Stout, giving researchers a major breakthrough in understanding the behavior of the virus.
Meanwhile keep riding your ebike out in the Sunlight, stay away from crowds, and build up your immunity from great exercise. This virus affects your respiratory system, and the higher your METS, the better.
A healthy person, not an athlete but an ordinary healthy person, can typically sustain a range of 1 MET (sleeping or sitting quietly) to roughly 10 METS. Each MET is about 3.5 VO2 points, more or less. Thus, if you know your VO2Max you know, more or less, what your METS capacity is. (This relationship isn't exact, but the estimates you can get without a lab test are close enough for this purpose.)
3. Moderate exercise (e.g. walking at ~3 mph) requires somewhere around ~3-4 METS.
4. Vigorous exercise is typically defined as 6 METS or above.
5. Climbing Stairs has been shown to be somewhere between 8 and 9 METs, or materially into the vigorous exercise realm.
6. Many runners, even reasonably-elderly ones can radically exceed 6 METS.
Incidentally, in a few months of effort you can go from a capacity of ~5 METS to quite close to 10.
People do it all the time; it's called Couch-to-5k and while it takes effort, most people can accomplish that in ~3-4 months.
So why 10 METS ? Well if you cannot climb stairs without becoming winded you're in quite a bit of trouble and it doesn't matter whether that's due to asthma, COPD or just generally poor physical condition. Presume that you get hit hard enough that this bug takes 5 METS out of your peak capacity at its worst. If you can only barely reach 6 you're basically at risk of death! Add some cardiac compromise and the risk goes up quite materially. Basically, this virus attacks your lungs ability to move oxygen and CO2. The stories you hear about smokers (men) in Asia getting hit harder by this than anyone, are true.
So get ebiking, and even turn the motor off throughout yoru trips, to make yourself do some real oxygen exchange.
