As previously mentioned in a post above, the UK forecast likely had lots to do with major moves in policy in the US.

Also concerning is the trajectory of cases. I received the following spreadsheet a few days ago. It is based on data compiled by Johns Hopkins. It shows that we are on the same track as Italy, roughly 10 or 11 days behind in terms of total numbers (though with far more widespread cases geographically, and with areas that have likely had more prolonged unrecognized community spread).
If you're wondering about current data, the Johns Hopkins website as I write this on 3/17 lists 6362 confirmed infections and 108 deaths in the US. The main point, though, is that we are on much more of an Italy/France/Spain slope as opposed to South Korea. I don't know, but would suspect that the higher number of deaths in Italy is due to two effects: an older population at baseline, and a health system that is was already beginning to be overwhelmed by the analogous March 6th date (matching the March 17th date in the US).
As for things that you can do individually to lessen risk, there is a some emerging evidence that use of Ibuprofen or other NSAIDs, ACE inhibitors
(ACE list) or Angiotensin Receptor Blockers (ARBs - an alternative to ACE inhibitors)
(ARB list) may increase overall risk for bad outcomes with COVID-19. The thinking is that these medications all increase ACE2 expression. ACE2 happens to be the receptor that the virus attaches to, causing infection. More receptors equals a higher viral burden with initial exposure. Might be worth a discussion with your doctor if you are in an at-risk group to switch to a different medication for basic pain control or blood pressure control for the next few months.
