Yesterday, Amory Lovins spoke about infectious repititis.

The infectious case was isolated from other patients.

We're treating cancer almost like it's an infectious disease.

New infectious diseases appear or reappear every few years.

Eighty percent of what walked in the door, in terms of illness, was infectious disease third world, developing world infectious disease, caused by a poor living environment.

Because when we're dealing with infectious diseases, we're dealing with living systems.

And they put me in an infectious disease ward at the hospital.

And so now of course we have this global problem in infectious diseases.

And when I went online and looked at the infectious read about the disease,

Suspecting that we both were in a house Where the infectious pestilence did reign,

And the people who avoid that have 30 percent less infectious disease or something.

We think that there is very very likely to be some sort of infectious culprit.

And this has turned out to be very effective in fighting certain intransigent infectious diseases

I'm an infectious disease physician, and in the early days of HlV, before we had our medications,

No longer do the poor and vulnerable need to be threatened by infectious diseases, or indeed, anybody.

We are afraid that crash may have caused the spread of an infectious virus... through this area.

I trained as an infectious disease physician, and I finished just as the HlV AlDS epidemic was unfolding.

Scientists around the world were intrigued by this cancer, this infectious cancer, that was spreading through the Tasmanian devil population.

But as I said earlier, this kind of logic applies across the board for infectious diseases, and it ought to.

Modern medicine in the late 19th century began to make major breakthroughs against the infectious diseases that killed a lot of people.

But a lot of money has been thrown out at the local level and at the federal level to look at infectious diseases.

And so that's the basic thing doctors are trained to do, and it's miraculous in the case of infectious disease how well it works.

In fact, the infectious agent of disease in this cancer is something altogether more sinister, and something that we hadn't really thought of before.

It's infectious repetitis, and we might as well try to have a theory of what's going on when that happens so that we can understand the conditions of infection.

The coming Third World War can be prevented only if we can awaken enough people, so those people become infectious and go on awakening other people in a chain.

When humans were hunter gatherers, roaming the wild savannas, we were never in one place long enough, and settlements were not large enough to sustain the transmission of infectious microbes.

Now, I had been working on other topics the emergence of infectious diseases, which come out of the natural ecosystems of the Earth, make a trans species jump, and get into humans.

So what doctors are mostly trained to do is diagnose that is, put you into a category and apply a scientifically proven treatment for that diagnosis and that works great for infectious diseases.

Humans are facilitating the spread of infectious diseases by shipping over 100 million amphibians around the world each year for use as food, pets, bait, and in laboratories and zoos, with few regulations or quarantines.

Washing is the antidote to the sort of bugs, the common infectious diseases of the eyes, the ears, the chest and the skin that, if they occur in the first five years of life, permanently damage those organs.

In the last century that's the one that was seven years ago half a billion people died from smallpox more than all the wars in history, more than any other infectious disease in the history of the world.

And so we wondered how we could let the amazing ideas that happen at TED, which are after all the most infectious ideas I have ever seen, boy, if you could see those into the world, what might happen?

And the focus when I'm talking about the diarrheal organisms, as well as the focus when I'm talking about any organisms that cause acute infectious disease, is to think about the problem from a germ's point of view, germ's eye view.

The good news is that we're at a moment in time when science, technology, globalization is converging to create an unprecedented possibility the possibility to make history by preventing infectious diseases that still account for one fifth of all deaths and countless misery on Earth.

The infectious diseases Cochrane Group, which are based in Italy, has been trying to get the full data in a usable form out of the drug companies so that they can make a full decision about whether this drug is effective or not, and they've not been able to get that information.

So, hopefully, we will go from being the art of medicine more to the science of medicine, and be able to do what they do in infectious disease, which is look at that organism, that bacteria, and then say, This antibiotic makes sense, because you have a particular bacteria that will respond to it.
