Contagious illnesses people will not be allowed to perform hajj, according to the Saudi government.

In a press release issued on Monday (November 10) the Ministry of Religious Affairs said, pilgrims may face corrective and regulatory actions if non-eligible individuals attempt to travel.

Each pilgrim must obtain a health certificate confirming they are free from medical risks that could hinder their participation in hajj, it said.

Letters detailing the rules have been sent to concerned countries.

The ministry said, pilgrims with non-functioning major organs—such as those undergoing dialysis for kidney failure, suffering from serious heart disease, or lung disease requiring continuous oxygen support—will not be permitted to perform hajj.

People with infectious diseases such as tuberculosis or viral hemorrhagic fever, as well as cancer patients undergoing chemotherapy or other intensive immunotherapy, will also be barred from performing Hajj.
