Donald Trump has made an excellent political move, that will have no health benefits. A travel ban will not work.

I have woken up to find that Donald Trump has increased the travel ban due to COVID19.  Well, bits of one, this being a ban on travel from nations who are in the Schengen Agreement area.  

This move will have much more of an effect on how the American public view him, but little on this disease.  COVID19 is already in the USA and the rates are probably greater than have been tested considering the way the USA has not been able to test as many people as has happened in Europe.  Of course, Trump has decided to blame Obama for this.  But while he wanted to cut funds to the CDC which is responsible for managing the response to this in the USA, despite Ebola, it is uncertain if these cuts have taken effect.  

But travel bans do not work.  People in the UK had called for a travel ban when this started to stop people coming in from China.  But our first national to have it, contracted it in Singapore and brought it to the UK via France.  There is only one nation to have imposed more strict bans on travel due to COVID, this being North Korea, and this has not worked there to prevent it entering the nation, though it is unclear if they will be able to limit any spread or not with the measures that they have put in place.  And when it comes to this new travel ban, people in the Schengen Agreement area will find ways to get around this by travelling to other destinations, including the UK before flying to the US.

To put it simply, the travel ban that Trump has imposed is unlikely to do much to prevent the spread of COVID19, but it will appeal to many voters, even though it makes little sense.
