The Church of Jesus Christ of Latter Day Saints in Samoa has cancelled all their services and gatherings until a measles-related state of emergency passes.
The government declared a state of emergency on Friday night to assist it in dealing with an epidemic that has claimed at least six lives.
All schools and universities have been closed and government examinations scheduled for this month have been postponed indefinitely.
Hospitals are also implementing new policies with only one family member or caregiver allowed to attend to a patient and, unless they are requiring medical attention, no child under the age of 18 can visit a medical facility.
Police have been instructed to keep the peace, support staff and families of the hospitals, and attend to assisting with the monitoring of visitors.
The declaration also includes a ban on children attending public gatherings.
The church, which has 160 wards in Samoa, said their move to close services followed the government's lead.
Other denominations are continuing their meetings.
