"UPDATE 4/22/2020:
The Navajo Nation Government has extended its declaration of a state of emergency and also extended the closure of Navajo Nation government offices and related entities until May 17th, to help slow the spread of C-19 on the Navajo Nation. The previous Executive Order was set to expire on April 26th. However, this does not necessarily mean everything is opening up on the 17th – the Nation will determine the next plan of action – check back for the next update." (re:
