According to an answer to a similar question, IATA has the travel rules published here: https://www.iatatravelcentre.com/international-travel-document-news/1580226297.htm
However, there are missing countries and possibly missing rules.
For example, Romania is not listed there, but people coming from Italy, South Korea etc. should stay in quarantine 2 weeks.
Is there another way to find out what are the travel rules related to the new Coronavirus?
