MECCA : Muslim pilgrims from around the world are pouring into the holy city of Mecca in Saudi Arabia, undeterred by the spread of the MERS virus which has killed 284 people in the kingdom. The faithful who dream of visiting Islam's holiest shrines in Mecca and Medina travel to western Saudi Arabia to perform the lesser umrah pilgrimage throughout the year. ‘We have received warnings by authorities in our country about MERS and were informed of the importance of taking precautions,’ said 45-year-old Abdullah, a pilgrim from Malaysia. Wearing a mask, Abdullah said he applies disinfectants as he enters the crowded Grand Mosque in Mecca. ‘God will protect me,’ he said. More pilgrims are expected to arrive with the approach of the Muslim fasting month of Ramadan, which starts late in June, and sees hundreds of thousands descend on Mecca for umrah.But numbers will rocket when the faithful arrive for the hajj pilgrimage, the largest annual religious gathering worldwide, which takes place this year in October. Local authorities in Mecca are distributing leaflets and brochures containing advice on hygiene and measures to minimise the risk of infection by the mysterious Middle East Respiratory Syndrome.Tunisian pilgrim, Safia Bin Mohammed shrugged off the fears of MERS. ‘I am not afraid,’ she said. ‘It was not easy to come here, so I couldn't have postponed my pilgrimage,’ said the 56-year-old woman, insisting she was ‘complying with the medical precautions.’ In a preemptive measure to avoid a potential importation of the virus, which has reached more than a dozen countries and as far afield as the United States, Tunisian authorities are advising their nationals to postpone their plans for pilgrimage this year.The cases outside the Middle East relate to people who became ill while in the region, with some involving pilgrims travelling to Mecca. Last year, five million pilgrims visited the kingdom for umrah and hajj. This year, the number of umrah pilgrims has reached 4.8 million since the start of the lunar Muslim calendar in October, according to official statistics. Fears mounted in April when several cases of infection were registered in the western city of Jeddah after MERS had been largely confined to Eastern Province, where it first appeared in April 2012.The port city of Jeddah, which lies 80 kilometres (51 miles) north of Mecca, is the main entry point for pilgrims. But Saudi Arabia's hajj ministry dedicated specifically to the annual pilgrimage has not yet taken any special measures related to MERS. MERS is considered a deadlier but less transmissible cousin of the SARS virus that appeared in Asia in 2003 and infected 8,273 people, nine percent of whom died.
