Dr. Larry Brilliant played a key role in eradicating smallpox from the world – so what are the biggest dangers humanity faces now? Brilliant rates politics as on-par with infectious disease.
The greatest global threats to health can be divided into two categories, explains epidemiologist and former head of philanthropy at Google, Dr. Larry Brilliant: there is the biological, and the socio-political. In the last 30 years, there have been at least 30 heretofore unknown viruses that have jumped from animals to humans, for worrying reasons Brilliant attributes to modernity and our increase in animal protein consumption. Still, the socio-political threats are the more immediately dangerous. There are centrifugal forces at play that are pushing society to two extreme camps. The domestic and global division caused President Trump’s ‘America First’ mentality and disregard for public health leaves us vulnerable to new viruses that, if they aren’t detected early enough, could be the next pandemic. "Right now because of the re-organization and nationalism… and dislike for the United Nations and its agencies, I think we're in a period of grave vulnerability," says Brilliant. Larry Brilliant is the author of Sometimes Brilliant: The Impossible Adventure of a Spiritual Seeker and Visionary Physician Who Helped Conquer the Worst Disease in History.
