Saudi Arabia, which has barred pilgrims from Sierra Leone, Liberia and Guinea from the Haj due to Ebola concerns, will allow Nigerians to attend, an official was reported as saying, suggesting the smaller outbreak there was less worrying.

Guinea, Liberia and Sierra Leone have been worst hit by an outbreak of the disease in West Africa, with a combined death toll in those three countries recording  2,097 since March, the World Health Organization (WHO) says.

A further eight people have died in Nigeria, out of 23 cases, and there has been one confirmed case in Senegal.

There are no approved Ebola vaccines or treatments.

Saudi Arabia said in April it would not issue visas for the 2014 Haj to pilgrims from Sierra Leone, Liberia and Guinea due to the Ebola outbreak in those countries.

Millions travel to Makkah each year for the Haj pilgrimage that all Muslims must perform at least once in their lifetime, if they are able. This year's will take place in October.

The Arab News daily quoted Mohammed Al-Khasheem, deputy health minister for planning and development, as saying there was no need to worry about Nigerians coming on pilgrimage.

"We have not stopped issuing Haj visas to Nigerians and we know that about 70,000 pilgrims come from the African country every year," he was quoted as saying.

"The WHO knows the situation in Mina and Arafat during the Haj season and there is no need to worry about a few Ebola cases that have occurred in Nigeria," he said, referring to holy Haj sites in Saudi Arabia.

"We have taken precautionary measures to prevent an Ebola outbreak in the kingdom during the Haj season," Al Khasheem said. "We have made early preparations for the annual pilgrimage," he said.

He said the ministry's department for preventive medicine is in constant contact with the WHO on the latest developments on Ebola and other infectious diseases. - Reuters
