For most people, the new coronavirus causes mild or moderate symptoms such as fever and cough that clear up in two to three weeks.

But for some — especially older adults and people with existing health problems — it can cause more severe illness, including pneumonia and death.

The Navajo Nation’s current 57-hour weekend lockdown remains in effect. It includes the closure of all businesses to deter traveling and help prevent the further spread of the coronavirus.

The tribe’s reservation stretches into northeastern Arizona, northwestern New Mexico and southeastern Utah.
