Health authorities around the world will have to be extra vigilant before, during, and after the pilgrimage to Mecca to contain this new virus since many of the patients suffering from this disease have had no animal contact, pointing to a possible human to human transfer.

In the case of the MERS-CoV ( Middle East respiratory syndrome coronavirus) the primary host is thought to be an insect eating bat, Neoromicia Zuluensis. This makes the camel connection even more puzzling since a blood sucking vampire bat would have been easier to connect to the camels. , .

Since majority of the deaths have occurred in Saudi Arabia, the annual pilgrimage to Mecca can be a testing ground for how far and widely MERS-CoV will likely travel this year after the Hajj, as devotees return to their home countries. Adding to the possibility of a massive pandemic outbreak is the fact that majority of the pilgrims are elderly people, and a large number may be immuno-compromised.
The World Health Organization is advising pilgrims that are planning to undertake Umra, or Hajj to use caution and minimize contact with those who may be suffering from respiratory illnesses, and if already contracted keeping away from others to avoid infecting them.
