Published recently by the Minister of Transportation of Argentina.  Below is the link to Mario Meoni’s announcement.  Also below is the gist of the communication in English.

Highlights:  Starting at midnight on March 19th, all domestic planes, long distance trains and buses are suspended completely until midnight March 25.  This is to prevent people who are not taking the health crisis seriously from travelling during the long weekend (March 23 and 24 are holidays in Argentina). They will also be checking roads. The government wants people to understand that they have to stay indoors and are not on vacation. Normal buses and trains will take only seated people, no passengers will be allowed to stand.
