[30] Foreigners, especially those from developing and underdeveloped countries such as Nigeria, Kenya, Burundi, Congo, Malawi, Bangladesh, Oman and Iraq, come to the city for advanced medical care.
[36] With more than 75 percent of the medical tourists being from the Middle East, hospitals in the city are vying for 'halal' certification.

Located at Elavur village, 40 km from the city centre, the project will be executed in three phases.
The bio hospital is expected to be the first of its kind in India, designed as tertiary care in all sub-specialities of medicine supported by modern basic sciences including stem cell technology, tissue engineering and nanotechnology, which would also focus on integration of traditional and alternate medicinal technologies such as ayurveda, naturopathy, and siddha to the services.
