Most dangerous is the heavy death toll in Iran, which means that there is - and has been for a good month+ - a very high (higher than anywhere outside of China) number of infected patients there, either covered up (until it became too big to hide - sound familiar?) or woefully un-diagnosed (likely a combination of both). And Iran, while not that well connected to the US, is connected to EU, Canada, etc. closely, and that could become just the tipping point and the vector from which this becomes a global pandemic, as the disclosure of the problem - a very serious problem - from there came just a few days ago, and again the heavy death toll (highest, by far, anywhere outside of China) is a clear indication of the gravity of the situation there. The directly adjacent countries and some others have already closed their borders to Iran (as have several countries also to Korea and Japan).
