DHAKA -- Only scientists should study the origins of COVID-19, the leader of the Bangladesh Medical Association, the largest nationwide professional body of medical doctors in the country, told Xinhua on Tuesday.

"If we have a clear and transparent idea about its origins or source, it will be an easy task to deal with the virus," said Mustafa Jalal Mohiuddin, the association's president.

Mohiuddin, a former Member of the Bangladesh Parliament, hailed China for supporting his country with COVID-19 vaccines.

"Definitely we applaud Chinese support," he said, adding that if rich countries fail to help their less fortunate counterparts with vaccines, medical equipment and technology, the world can't expect a return to normalcy.

Mohiuddin said the Chinese government has taken the right approach to controlling the virus.
