General textbook guidelines for R0 of 2 to 4 is to keep containment going for at least 3 months, plus I'll add another month there (end of April). But then again, I don't know the data about virulence very well, because its not that available (still hard to know). The issue is the juxtaposition with Flu season. I would try to contain as much as possible until the end of April. But then, I think there are plenty of cases where containment is a long term tactic (Iran?). The most troubling aspect is that we haven't seen a situation where we lost control of tracing as much as right now for a long time, this usually can lead to the frontline being overwhelmed. Community spread is happening faster than expected (my theory is that intestinal gas plumes is how it spreads faster in contained areas).
We got lucky with SARS, we are way past the point where luck is a factor now. Institutions have to work for real and make strong calls or the consequences will be problematic.
I'm on 2000mg of Quercetin a day - this might be something we'll mass produce as a pharmacological preventive intervention. There are some clinical studies of Quercetin vs. SARS showing its efficacy, and a researcher from Montreal is leading a clinical study in China to test it the field on already sick patients. I'm thinking it will be better as a preventive (reduce the R0).
Currently in Panama about to fly back towards Canada.
