The death of an umrah pilgrim on AirAsia X flight D7 171 from Jeddah to Kuala Lumpur on Friday night was not due to infection from the Middle-East Respiratory Syndrome Coronavirus (MERS-CoV).

Health director-general, Datuk Dr Noor Hisham Abdullah said autopsy conducted on the 64-year-old Indonesian found it was caused by a heart attack.

"The body was sent to Serdang Hospital for autopsy and samples were sent to Sungai Buloh Hospital laboratory to determine the cause of death.

"Since he had just performed the umrah, samples were taken for MERS-CoV screening and found to be negative," he said in a statement today.

Dr Noor Hisham said in the holy land, the victim suffered from fever, cough, shortness of breath and loss of appetite for a few days and sought treatment from clinics.

"During the flight from Jeddah to Kuala Lumpur, he suffered from breathing difficulty and later died," he added.
