There is really only one way of stopping the spread of this virus worldwide and that is to work at stopping the spread of the virus where it is most virulent. 

Stopping/checking flights from infected areas sounds good but is pointless unless either every other country in the world does the same or we totally stop all movement in or out of the country.

An almost aside of an item was on the news the other day about grave diggers who are at real risk, (no suits or breathing equipment), complaining because they hadn't been paid for two weeks!

Aid in the way of equipment and money needs to be directed urgently towards the infected areas.
