So it is almost certainly a vast underestimate of the number of cases. That's all I said. The various reasons we are almost certain that this is true, ranging from from instances of probable community transmission to estimates of RNA sequence variation have been discussed multiple times I said previously that we should stop all international travel, which may be excessive. I canceled a work related trip to Italy myself and after that my employer cancelled all work related international travel and requires any personal international travel to be reported to HR and for people traveling to the highest CDC alert level countries to self quarantine for 2 weeks upon returning. I think all employers and local health departments should institute similar restrictions. This might minimize new new infectious cycles from starting and could slow down the spread.
