SYDNEY – On April 6, Australian researchers will start trials of the tuberculosis drug Bacillus Calmette-Guerin (BCG) as a possible treatment of the deadly Covid-19 coronavirus now spreading across the globe.

It represents perhaps the most hopeful test yet of an existing medicine currently in everyday use to tame the highly contagious Covid-19 virus.

“I am hopeful that within three months we will have a good idea which drugs are good and which drugs are bad,” said Australian National University geneticist Gaetan Burgio. “The field is moving very quickly.”

Fast action is required as the pandemic jumps from global epicenter to epicenter, with caseloads currently exploding in the United States while still ravaging Europe and gaining ground in South America after originating in China.
