If you already have one, do some science. Take a reading today, even if you feel good, especially if you feel good. Part of the process is noticing CHANGE. Keep taking them. Don’t have one? They’re not terribly expensive ($30-50) and it’s always fun to have new toys when you’re stuck in the house.
Got a thermometer? make sure it works. Make sure others know how it works. Take some baselines in the next few days. It’s interesting to do this while not sick so you can tell what actually is unusually high for you.

Too bad we don’t have one of these. You can be pretty sure that the disinformation machine is pointed at us, as well, so many of the activities described here as being pointed at Ukraine have their American analogies from the same sources.
Oh yeah, and this time around we have ultra rich script kiddies who have taken the russian models to heart and so now we have home grown disinformation campaigns

This guy does some excellent videos making really hard maths pretty and fun to learn about.
Pay attention to the gray part at the top of the graphs. These are the “removed” i.e. (sick and recovered) or (sick and not recovered) aka dead. Presumably no longer infectable, but there is not definitive evidence that that’s really a thing. EDIT: These are also the “sick and being removed to quarantine”, which in our current situation is NOT a thing.)
Sweden went a different way than many of their neighbors. They didn’t have a draconian lockdown, they just told people to be mindful and act like adults. There were more deaths, but they are on the other side and claiming that they’ll have “herd immunity” by May.

These animations are made using manim, a scrappy open-source python library: https://github.com/3b1b/manim
Code for this video: https://github.com/3b1b/videos/blob/master/_2020/sir.py
Honestly, given that the code for that video is meant for demo purposes, and not meant to reflect the true data of COVID-19, if you want to apply these ideas to the current situation I’d recommend looking for more professional epidemiological modeling tools that are less centered around animations and pedagogy and more focused on accurate predictions. For example, the Institute for Disease Modeling has a lot of models free for people to look at and play with.

Lots of people are using thermometer as a gauge for current health yet many people can stay apparently healthy.
The doc in this video suggest that perhaps a pulse oximeter can give some early indication of decrease in lung function, and that can help people determine that it’s time to go go hospital but not too late.
If you you are occasionally checking your temperature and own one of these widgets it might be worthwhile to add this, you know, for science
Nowhere is this crisis more deeply felt than by the essential workers on the front lines. Dr. Richard Levitan, an airway specialist who has practiced emergency medicine for over 30 years, is well aware of the urgency of their work. When the virus began to overwhelm New York City at the end of March, he rushed from his home in New Hampshire to volunteer at Bellevue Hospital, where he trained. Dr. Levitan recently wrote an op-ed in the New York Times detailing what he’s learned from treating COVID-19 patients at Bellevue. He also has co-founded a charitable organization, Prone2Help, which provides healthcare workers with free cushions, since doctors have found placing coronavirus patients on their stomach–called prone positioning–helps increase the amount of oxygen getting to their lungs. Dr. Levitan joins Hari Sreenivasan to discuss his work.
