The source of the MERS-CoV is not yet fully clear. A coronavirus very similar to the one found in humans has been isolated from camels in Egypt, Oman, Qatar, and Saudi Arabia. . It is possible that other reservoirs exist. However, other animals, including goats, cows, sheep, water buffalo, swine, and wild birds, have been tested for MERS‐CoV, but so far none have been found in these animals. These studies combined support the premise that dromedary camels are a likely source of infection in humans.
