Sierra Leone's government has declared a five-day lockdown in the country's north to step up efforts to contain the Ebola epidemic, while making an exception for Christmas.
"Muslims and Christians are not allowed to hold services in mosques and churches throughout the lockdown except for Christians on Christmas Day (Thursday)," Alie Kamara, resident minister for the Northern Region, said.
The lockdown announced on Wednesday is designed "to intensify the containment of the Ebola virus", he said, adding: "We are working to break the chain of transmission."
Deputy communication minister Theo Nicol said "the lockdown for five days ... is meant for us to get an accurate picture of the situation", adding: "Other districts will carry on with their own individual lockdown after this if they deemed it necessary."
Ebola has killed more than 7500 people, almost all of them in west Africa.
Sierra Leone, Liberia and Guinea are the three nations worst-hit by the epidemic, and Sierra Leone recently overtook Liberia as the country with the highest number of Ebola infections.
Kamara said shops and markets would be closed throughout the period, and "no unauthorised vehicles or motorcycle taxis" would be allowed to circulate "except those officially assigned to Ebola-related assignments".
Among "key objectives" is to allow health workers to identify patients, Kamara said.
Sierra Leone declared a state of emergency on July 31 after the Ebola outbreak and imposed restrictions on the movement of people.
As of Wednesday six of the country's 14 departments have these restrictions in place.
On December 12, the government announced a restriction on large Christmas and New Year gatherings.
Several residents in the country's north told AFP by telephone that locals had largely been conforming to the new strictures.
"The streets are deserted and people are staying indoors or sitting in their backyards," said Felix Koroma, in Makeni, in the district of Bombali.
"Although the district is predominantly Muslim, it is traditional for Muslims to join with Christians to celebrate Christmas but from what I can deduce, it's going to be a bleak occasion," he added.
Sarah Tucker, in Port Loko district said the only activity she could see was "medics moving from house to house" looking to remove the sick from their homes.
But some residents said they had not been given adequate warning to stockpile supplies.
"The notice given was too short and it was difficult for us to keep food in the house," a resident of Magburaka, in Tonkolili, who wished to remain anonymous, told AFP.
"The lockdown is good but we are worried over what to eat until it ends."
The lockdown came after it was announced that a fourth member of the UN mission in neighbouring Liberia had been hospitalised after testing positive for the virus.
The UN employee tested positive on Tuesday and was immediately transferred to an Ebola treatment unit, said Karin Landgren, the special representative of UN chief Ban Ki-moon.
"UNMIL is taking all necessary measures to mitigate any possible further transmission - both within the mission and beyond," Landgren said, referring to the United Nations Mission in Liberia.
Liberia tops the number of Ebola deaths in the world with 3376 fatalities but has seen a clear decrease of new transmissions in the past month.
