The Navajo Nation changed its 57-hour weekend lockdown to a 32-hour weekend lockdown that began at 9 p.m. Saturday and will end at 5 a.m. Monday.

Tribal officials said the daily curfew also will be changed to those same hours on the vast reservation that covers parts of Arizona, New Mexico and Utah.

But for some people who contract the virus, especially those who are older or have underlying health conditions, it can cause more severe illness and death.
