by talking a little bit about my credentials to bring this up with you,

because, quite honestly, you really, really should not listen

to any old person with an opinion about COVID-19.

So, I've been working in global health for about 20 years,

and my specific technical specialty is in health systems

and what happens when health systems experience severe shocks.

I've also worked in global-health journalism.

I've written about global health and biosecurity

about the major global health threats facing us as a planet.

I have supported and led epidemiology efforts

that range from evaluating Ebola treatment centers

to looking at transmission of tuberculosis in health facilities

I have a master's degree in International Health.

My specialty isn't patient care or taking care of individual people.

My specialty is looking at populations and health systems -

what happens when diseases move on the large level.

If we're ranking sources of global-health expertise

1 is some random person ranting on Facebook,

and 10 is the World Health Organization -

I'd say you can probably put me at like a 7 or an 8.

in some of the media noise around COVID-19.

and coronaviruses are a specific subset of virus,

and they have some unique characteristics as viruses.

They use RNA instead of DNA as their genetic material,

and they're covered in spikes on the surface of the virus,

and they use those spikes to invade cells.

Those spikes are the corona in coronavirus.

because, until December, we'd only heard of six coronaviruses.

it just had its gene sequencing, it just got its name -

If you remember SARS - severe acute respiratory syndrome -

or MERS - Middle East respiratory syndrome,

and they're both called respiratory syndromes

they don't make you bleed from the eyeballs,

they don't make you hemorrhage, they head for your lungs.

It causes a range of respiratory symptoms

that go from stuff like a dry cough and a fever

all the way out to fatal viral pneumonia.

And that range of symptoms is one of the reasons

it's actually been so hard to track this outbreak.

but so gently, their symptoms are so mild

that they don't even go to a health care provider.

Children, in particular, have it very easy with COVID-19,

which is something we should all be grateful for.

which means that they transmit from animals to people.

Some coronaviruses, like COVID-19, also transmit person to person.

The person-to-person ones travel faster and travel farther,

Zoonotic illnesses are really hard to get rid of

where we can abolish it in farmed animals,

but it keeps coming back every year because it's brought to us by wild birds.

because avian influenza doesn't transmit person to person,

but we have outbreaks in poultry farms every year all over the world.

COVID-19 most likely skipped from animals into people

This is not the last major outbreak we're ever going to see.

There's going to be more outbreaks, and there's going to be more epidemics.

And it's a result of the way that we, as human beings,

Human choices are driving us into a position

Part of that is about climate change and the way a warming climate

makes the world more hospitable to viruses and bacteria.

But it's also about the way we're pushing into the last wild spaces on our planet.

When we burn and plow the Amazon rain forest

so that we can have cheap land for ranching,

when the last of the African bush gets converted into farms,

when wild animals in China are hunted to extinction,

human beings come into contact with wildlife populations

that they've never come into contact with before,

and those populations have new kinds of diseases:
