COVID-19 Information


Please keep in mind this information is subject to frequent changes, and is current only through the most recent update. Last updated December 22, 2020. Cover image is public domain from CDC.

Contact Tracing

If you live in California, we now have CA Notify, a contact tracing app that uses anonymized Bluetooth handshakes to keep a record of all the (participating) phones you come in contact with. If you test positive, you can send an anonymous notification to everyone who might have been exposed. California was a bit slow to get this set up compared to some other states—I’ve started a list or you can check the app store on your phone to see if there’s something similar where you live.

General Tips

  1. WEAR A MASK.
  2. Stay away from people even if you feel well (aka “social distancing”).
  3. If you think you contracted the virus, stay home and don’t go to the ER unless you can’t breathe, feel faint, can’t keep fluids down.
  4. Take acetaminophen (also known as Tylenol) for fever/aches
  5. Exercising by yourself outside is ok.
  6. Bring food/supplies to elderly family members so they can avoid people–drop off supplies without direct contact.

Stuff I Wrote

Some of the things are either out of date or no longer as useful as they once were. When that happens I’ll move it down here.

  1. […] I think all of us in healthcare are trying to provide accurate and current information to our family and friends where possible, but the information changes day to day, sometimes even hour by hour. To deal with this some of my colleagues have put together a “living document” with updated information. That, along with some of the articles and resources I’ve found myself repeatedly linking, is collected here. […]

  2. […] home if we can. I am not qualified to predict what may happen or to give medical advice (you can read that here). I just know that we must all stay home and should wear a home made mask when we leave the house […]
