What Are the Biggest Global Threats to Public Health?

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.

Larry Brilliant: If I were asked what are the greatest global threats to health today I would divide that into two parts. One, of course, would be the biology the Ebola, Zika, bird flu, swine flu world and I will talk about that. But far more than that are the kind of centrifugal forces that are pulling us a part as a nation, pulling us apart as a world, the deterioration of all of the international and national organizations that we depend upon to keep us safe. The World Health Organization, which failed to protect the world against Ebola and didn't do a great job on Zika either and it will have a new leader in May of this year. There are a couple of candidates who are terrific and some that aren't so good, but either way WHO is going to be going through a period of years of introspection and re-organization.

We have a new Secretary General of the UN. He's a good guy. He's from Portugal, Gutierrez. He just started. It will be a while before he can find all the bathrooms in the UN buildings. We've just lost the head of CDC. We have a new acting head of CDC, who is also good. But CDC will go through a headless period. And then we have Trump and we have a White House which would almost reflexively discard anything that had the word of public in it and one of those words is public health. And they have not shown a keen interest in pandemics. And the whole idea of America first, which might be good for many things, is singularly not good for a global pandemic. It's an oxymoron. It doesn't work. These centrifugal forces that put us in a period of vulnerability are the gravest threats.

On the biology side, in the last 30 years we've had 30 novel here before unknown diseases that jumped from animals to humans, they're almost all viruses. In addition to Ebola and Zika and bird flu and swine flu we have coronaviruses like SARS and MERS, we have arboviruses and a lot of other viruses that continue to jump at the rate of about one a year. That rate is increasing slightly. I don't think it's increasing at a catastrophic rate. The causes of its increasing are that animals and humans are living in each other's habitat now more than ever. Part of that is the clear cutting of forests to grow soybeans and things of that nature. Another reason is that as countries have gotten slightly more wealthy they begin to consume more protein and more animal protein.

I remember when I work at a Google I gave a talk to 3000 young Indian Googlers in Hyderabad and I asked them to raise their hand if their grandparents were vegetarian. They all raised their hand. Then I asked them to raise their hand if their parents were vegetarians and about half raise their hand. And then I asked them if they were vegetarians and no one raise their hand. And I think that's leads to the increase in chickens and pigs that we've been saying in China and India, not pigs so much in India. And that means the kind of way in which Asia houses and farms are all together and you can go to Laos and see a pancake house that has pigs on the ground floor, chickens in the middle, and humans up on top. When pigs are eaten what's left to them is fed to the chickens, and when the chickens are eaten what's left of them is fed to the pigs. And of course everything is fed to humans. That's like a natural virus experiment. You really wouldn't want to do that if you were trying to keep the world safe from viruses.

So we are having more viruses jump from animals to humans for lots of different reasons related to modernity. And normally our ability to protect the world keeps apace with that, maybe even is a little bit ahead and every year we're a little bit safer. That's not true right now. Right now because of the re-organization and nationalism and re-organization and dislike for the United Nations and its agencies I think we're in a period of grave vulnerability. So it's those two things together.

 

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.

Navy SEALs: How to build a warrior mindset

SEAL training is the ultimate test of both mental and physical strength.

Videos
  • The fact that U.S. Navy SEALs endure very rigorous training before entering the field is common knowledge, but just what happens at those facilities is less often discussed. In this video, former SEALs Brent Gleeson, David Goggins, and Eric Greitens (as well as authors Jesse Itzler and Jamie Wheal) talk about how the 18-month program is designed to build elite, disciplined operatives with immense mental toughness and resilience.
  • Wheal dives into the cutting-edge technology and science that the navy uses to prepare these individuals. Itzler shares his experience meeting and briefly living with Goggins (who was also an Army Ranger) and the things he learned about pushing past perceived limits.
  • Goggins dives into why you should leave your comfort zone, introduces the 40 percent rule, and explains why the biggest battle we all face is the one in our own minds. "Usually whatever's in front of you isn't as big as you make it out to be," says the SEAL turned motivational speaker. "We start to make these very small things enormous because we allow our minds to take control and go away from us. We have to regain control of our mind."

New guidelines redefine 'obesity' to curb fat shaming

Is focusing solely on body mass index the best way for doctor to frame obesity?

Surprising Science
  • New guidelines published in the Canadian Medical Association Journal argue that obesity should be defined as a condition that involves high body mass index along with a corresponding physical or mental health condition.
  • The guidelines note that classifying obesity by body mass index alone may lead to fat shaming or non-optimal treatments.
  • The guidelines offer five steps for reframing the way doctors treat obesity.

  • The company's protein powder, "Solein," is similar in form and taste to wheat flour.
  • Based on a concept developed by NASA, the product has wide potential as a carbon-neutral source of protein.
  • The man-made "meat" industry just got even more interesting.
