COVID-19

Early in the pandemic,I analyxed the genetic sequences of coronavirus COViD-19 (SARS-CoV2) that were publicly available and created neighbor joining networks (trees). They would have been useful for tracking the geographic origins of an outbreak and keeping track of strains.  See links below.

Starting early April 2020, I had gathered evidence for what I think is the solution to the mystery that was growing for the seemingly baffling range of characteristics that made serious, even fatal, infection more likely, such as being a man or being very overweight. I had to leave the project for a while but got back to it and finished it up in late Septermber 2020  COVID-19 article

Tree info:

March 25, 2020 tree There are 104 publically available seqeunces. Notably absent are USA new sequences, including New York, New Jersey and Pennsylvnaia. Why aren't these being deposited as is standard for genetic data? Sequences from Valencia are striking with differences from other regions and each other. Valencia is all the way to the East of Spain, with Italy next door. Perhaps their sources are Italy whose explosion in cases may have allowed many surviving variants  Note perhaps NY would look just as diverse, were they to be availailable (most Italy sequences not available either). This alread;y increaseing diversity of the DNA from Valencia, whether from Italy or local, raises issue of new more virulent or deadly strains lurking within and also may limit the time that those recovered from a COVID-19 infection can enjoy immunity, especially with travel.  Finally, inspecting sequences from USA cruise ship finds many identical to original Chinese source virus. However, at least one is ve;ry diffrent and whether this reflects infection not actually from the curise ship or rapid mutation on the ship itself is unknown.   

 

 

 

   March 6, 2020 tree There are 48 publically available sequences. We can see the Illinois/CA 2 cluster may have been developing there for weeks, something not talked about in the news. Also note the greatest genetic diversity in the USA is in California; placement in the tree suggests this is not from community spread but from multiple independent episodes of infection from elsewhere.

Fun reviews:

"I haven't had a chance to actually read your book yet, but it looks fascinating." ALAN ALDA, award-winning actor, director, and science educator

 

"Your book was very inspirational and I kept putting it down to jot down ideas."DR. MARK S. RIDER, Clinical Psychologist, Texas

 

"I read the book (Cab Drivers), really loved it! I especially like how your tone in the book is casual, a few times I laughed out loud. That is my preferred way of reading and I bet student's will like it also in the case that it becomes assigned reading for someone." SABRINA PETERSON, graduate student, University of California, Riverside

 

"I was reading and reading and re reading and it looks like you were writing my mind. How
