Causes Of Middle East Respiratory Syndrome (MERS)

MERS-CoV is a zoonotic virus, meaning it can spread from animals to humans. Exposure to camels or camel products were the source of MERS-CoV infection in humans. The presences of antibodies to the virus have been found in camels in Saudi Arabia, Egypt and Qatar [2].

MERS-CoV is transmitted easily when a person comes in close contact with an infected camel. The virus can enter the human body through air or by the consumption of raw camel milk or uncooked camel meat.

The doctor will physically examine you and ask about your symptoms and your recent travel history. Then for diagnosis, samples will be taken from the patient's respiratory tract. Polymerase chain reaction testing (RT-PCR testing) is a diagnostic test that confirms the presence of MERS-CoV in the body [4].

Blood tests, chest X-ray, lung secretion test and kidney function tests can also help determine if a person has been infected or not.
