In a way I am for mandatory quarantine of any one coming into the country. I know that would be hard to do but it may be the safest,for the general public.
The virus will not be totally 'stopped' by travel bans or border walls! Most people who are infected will recover and a vaccine will be developed with the science and physician attention. There of course, will be those who will die before a 'cure' is found ! Travel bans will slow the development of a cure, as well as crippling the economic base of the countries of the world
The world health organization is stating that the travel ban could do more harm than good and I like to think that they have more expertise than politicians. Travel restrictions slow down getting needed supplies to affected areas. However, we need to be reasonable about travel and safety precautions until we know more about the virus.
"[W]e need to seriously reexamine our current policy banning travel from China and quarantining returning travelers. All of the evidence we have indicates that travel restrictions and quarantines directed at individual countries are unlikely to keep the virus out of our borders... Travel bans and quarantines will make us less safe if they divert attention and resources from higher priority disease mitigation approaches that we know are needed to respond to cases within the United States."
"I am always reluctant to implement travel bans because of the risk that they wind up being counterproductive. Travel bans hurt national economies and often encourage other countries to limit their transparency to avoid potential bans. Travel bans can also divert resources away from other urgently required activities."
