He found him and began to swim back to the shore.
According to his profile on the Jewish General Hospital, Wainberg's research focus at the time of his death was on finding "novel concepts" to prevent HIV infection in developing countries.
Batist noted he had co-published a paper with Wainberg on the topic of cancer bio-markers and said it was an indication of his brilliance he was able to make contributions to fields outside his immediate expertise.
Waineberg was a Medicine and Microbiology professor at Montreal's McGill University, where he received his bachelor's degree, as well as director of the McGill University AIDS Centre.
Dr. Wainberg identified 3TC (Lamivudine) as an antiviral, and it became one of the first effective treatments for people who contracted HIV. Other beach-goers went into the water and assisted his son in bringing him onto the shore.
"Mark Wainberg was a giant in HIV science".
Oil edges up as Saudis reported to back extension of production cuts
Rising production has come before record US oil stockpiles have had time to drain, putting pressure on regional prices. USA crude production is set to grow to 9.9 million bpd in 2018, from 9.22 million bpd this year.
A friend of, and informal adviser to, UNAIDS for many years, he also served as the President of the International AIDS Society from 1998 to 2000.
Dr. Wainberg said the world should also spend more money on getting antiviral drugs to the estimated 7 million people living with AIDS in the world who can not afford treatment.
Firefighters continued performing CPR as Dr. Wainberg was taken to hospital, where he died.
In recent years, Dr. Wainberg had once again returned to the lab.
The internationally renowned scientist, who was at the forefront of HIV research from the very beginning of the global AIDS epidemic, drowned on Wednesday while swimming off Bal Harbour in Florida, Radio Canada said. His ensuing AIDS research earned him honors such as the Order of Canada and the Legion d'honneur, the highest honors for civilians given by Canada and France, respectively.
