You are absolutely correct. I apologize for any misinformation I may have provided.
No, my opinion above is not based on any realtime data, as I believe that is still up in the air (no pun intended). But rather, I’m basing everything on my understanding of the basic viral molecular structure. Viruses have an outer shell called a capsid, and sometimes even coated with some proteins. These tend to harden during colder weather, hence increasing the survivability of the virus in finding a host. It also tends to liquefy during warmer temperatures, making the viral components susceptible to the elements, shortening the transmissibility of certain virus.
Now, the funny thing with nature is, as much as new things occur, it still follows patterns. This new virus is from the coronaviridae family, which we have at least 4 known circulating seasonal viruses around. My thought is it will take on the general characteristics of the family, and behave similarly.
You are right to say that anything at this time is pure speculation, so I could be wrong. However nature takes on patterns, and generalities rather than exceptions. Only time will tell.
