Why COVID-19 is hitting us now -- and how to prepare for the next outbreak

  • 0:01 - 0:05
    I want to lead here by talking
    a little bit about my credentials
  • 0:05 - 0:06
    to bring this up with you,
  • 0:06 - 0:08
    because, quite honestly,
  • 0:08 - 0:13
    you really, really should not listen
    to any old person with an opinion
  • 0:13 - 0:15
    about COVID-19.
  • 0:15 - 0:16
    (Laughter)
  • 0:16 - 0:20
    So I've been working in global health
    for about 20 years,
  • 0:20 - 0:25
    and my specific technical specialty
    is in health systems
  • 0:25 - 0:29
    and what happens when health systems
    experience severe shocks.
  • 0:29 - 0:31
    I've also worked
    in global health journalism;
  • 0:31 - 0:35
    I've written about
    global health and biosecurity
  • 0:35 - 0:38
    for newspapers and web outlets,
  • 0:38 - 0:40
    and I published a book a few years back
  • 0:40 - 0:44
    about the major global health threats
    facing us as a planet.
  • 0:44 - 0:48
    I have supported and led
    epidemiology efforts
  • 0:48 - 0:52
    that range from evaluating
    Ebola treatment centers
  • 0:52 - 0:56
    to looking at transmission
    of tuberculosis in health facilities
  • 0:56 - 0:59
    and doing avian influenza preparedness.
  • 0:59 - 1:02
    I have a Master's Degree
    in International Health.
  • 1:03 - 1:05
    I'm not a physician. I'm not a nurse.
  • 1:05 - 1:09
    My specialty isn't patient care
    or taking care of individual people.
  • 1:09 - 1:13
    My specialty is looking at populations
    and health systems,
  • 1:13 - 1:16
    what happens when diseases
    move on the large level.
  • 1:17 - 1:21
    If we're ranking sources
    of global health expertise
  • 1:21 - 1:24
    on a scale of one to 10,
  • 1:24 - 1:27
    one is some random person
    ranting on Facebook
  • 1:27 - 1:31
    and 10 is the World Health Organization,
  • 1:31 - 1:35
    I'd say you can probably put me
    at like a seven or an eight.
  • 1:35 - 1:37
    So keep that in mind as I talk to you.
  • 1:39 - 1:42
    I'll start with the basics here,
    because I think that's gotten lost
  • 1:42 - 1:46
    in some of the media
    noise around COVID-19.
  • 1:46 - 1:50
    So, COVID-19 is a coronavirus.
  • 1:50 - 1:54
    Coronaviruses are
    a specific subset of virus,
  • 1:54 - 1:58
    and they have some unique
    characteristics as viruses.
  • 1:58 - 2:01
    They use RNA instead of DNA
    as their genetic material,
  • 2:01 - 2:05
    and they're covered in spikes
    on the surface of the virus.
  • 2:05 - 2:07
    They use those spikes to invade cells.
  • 2:08 - 2:11
    Those spikes are the corona
    in coronavirus.
  • 2:12 - 2:16
    COVID-19 is known as a novel coronavirus
  • 2:16 - 2:20
    because, until December,
    we'd only heard of six coronaviruses.
  • 2:20 - 2:22
    COVID-19 is the seventh.
  • 2:22 - 2:23
    It's new to us.
  • 2:23 - 2:25
    It just had its gene sequencing,
  • 2:25 - 2:26
    it just got its name.
  • 2:26 - 2:27
    That's why it's novel.
  • 2:28 - 2:32
    If you remember SARS,
    Severe Acute Respiratory Syndrome,
  • 2:32 - 2:34
    or MERS,
  • 2:34 - 2:36
    Middle Eastern Respiratory Syndrome,
  • 2:36 - 2:38
    those were coronaviruses.
  • 2:38 - 2:41
    And they're both called
    respiratory syndromes
  • 2:41 - 2:44
    because that's what coronaviruses do --
  • 2:44 - 2:46
    they go for your lungs.
  • 2:46 - 2:49
    They don't make you puke, they don't
    make you bleed from the eyeballs,
  • 2:49 - 2:50
    they don't make you hemorrhage.
  • 2:50 - 2:52
    They head for your lungs.
  • 2:53 - 2:55
    COVID-19 is no different.
  • 2:55 - 2:59
    It causes a range of respiratory symptoms
  • 2:59 - 3:02
    that go from stuff like
    a dry cough and a fever
  • 3:02 - 3:05
    all the way out to fatal viral pneumonia.
  • 3:05 - 3:09
    And that range of symptoms
    is one of the reasons
  • 3:09 - 3:12
    it's actually been so hard
    to track this outbreak.
  • 3:12 - 3:17
    Plenty of people get
    COVID-19 but so gently,
  • 3:17 - 3:21
    their symptoms are so mild, they don't
    even go to a health care provider.
  • 3:21 - 3:23
    They don't register in the system.
  • 3:23 - 3:27
    Children, in particular, have it
    very easy with COVID-19,
  • 3:27 - 3:29
    which is something
    we should all be grateful for.
  • 3:32 - 3:34
    Coronaviruses are zoonotic,
  • 3:34 - 3:37
    which means that they transmit
    from animals to people.
  • 3:37 - 3:42
    Some coronaviruses, like COVID-19,
    also transmit person to person.
  • 3:43 - 3:46
    The person-to-person ones
    travel faster and travel farther,
  • 3:46 - 3:48
    just liked COVID-19.
  • 3:48 - 3:51
    Zoonotic illnesses
    are really hard to get rid of,
  • 3:51 - 3:54
    because they have an animal reservoir.
  • 3:54 - 3:57
    One example is avian influenza,
  • 3:57 - 4:02
    where we can abolish it
    in farmed animals, in turkeys, in ducks,
  • 4:02 - 4:07
    but it keeps coming back every year
    because it's brought to us by wild birds.
  • 4:07 - 4:08
    You don't hear a lot about it
  • 4:08 - 4:11
    because avian influenza
    doesn't transmit person-to-person,
  • 4:11 - 4:15
    but we have outbreaks in poultry farms
    every year all over the world.
  • 4:17 - 4:21
    COVID-19 most likely skipped
    from animals into people
  • 4:21 - 4:23
    at a wild animal market in Wuhan, China.
  • 4:25 - 4:27
    Now for the less basic parts.
  • 4:28 - 4:32
    This is not the last major outbreak
    we're ever going to see.
  • 4:32 - 4:36
    There's going to be more outbreaks,
    and there's going to be more epidemics.
  • 4:36 - 4:39
    That's not a maybe. That's a given.
  • 4:40 - 4:43
    And it's a result of the way
    that we, as human beings,
  • 4:43 - 4:45
    are interacting with our planet.
  • 4:45 - 4:48
    Human choices are driving us
    into a position
  • 4:48 - 4:51
    where we're going to see more outbreaks.
  • 4:52 - 4:53
    Part of that is about climate change
  • 4:53 - 4:56
    and the way a warming climate
    makes the world more hospitable
  • 4:56 - 4:58
    to viruses and bacteria.
  • 4:58 - 5:04
    But it's also about the way we're pushing
    into the last wild spaces on our planet.
  • 5:05 - 5:08
    When we burn and plow
    the Amazon rain forest
  • 5:08 - 5:10
    so that we can have
    cheap land for ranching,
  • 5:10 - 5:14
    when the last of the African bush
    gets converted to farms,
  • 5:14 - 5:19
    when wild animals in China
    are hunted to extinction,
  • 5:19 - 5:22
    human beings come into contact
    with wildlife populations
  • 5:22 - 5:25
    that they've never come
    into contact with before,
  • 5:25 - 5:28
    and those populations
    have new kinds of diseases:
  • 5:28 - 5:32
    bacteria, viruses,
    stuff we're not ready for.
  • 5:33 - 5:34
    Bats, in particular,
  • 5:34 - 5:37
    have a knack for hosting illnesses
    that can infect people,
  • 5:37 - 5:40
    but they're not
    the only animals that do it.
  • 5:41 - 5:45
    So as long as we keep making
    our remote places less remote,
  • 5:45 - 5:47
    the outbreaks are going to keep coming.
  • 5:49 - 5:54
    We can't stop the outbreaks
    with quarantine or travel restrictions.
  • 5:54 - 5:56
    That's everybody's first impulse:
  • 5:56 - 6:00
    "Let's stop the people from moving.
    Let's stop this outbreak from happening."
  • 6:00 - 6:05
    But the fact is, it's really hard
    to get a good quarantine in place.
  • 6:05 - 6:08
    It's really hard
    to set up travel restrictions.
  • 6:08 - 6:12
    Even the countries that have made
    serious investments in public health
  • 6:12 - 6:14
    like the US and South Korea
  • 6:14 - 6:16
    can't get that kind of restriction
    in place fast enough
  • 6:16 - 6:19
    to actually stop an outbreak instantly.
  • 6:19 - 6:23
    There's logistical reasons for that,
    and there's medical reasons.
  • 6:23 - 6:26
    If you look at COVID-19 right now,
  • 6:26 - 6:30
    it seems like it could have a period
    where you're infected and show no symptoms
  • 6:30 - 6:32
    that's as long as 24 days.
  • 6:32 - 6:36
    So people are walking around
    with this virus showing no signs.
  • 6:36 - 6:40
    They're not going to get quarantined.
    Nobody knows they need quarantining.
  • 6:43 - 6:47
    There's also some real costs to quarantine
    and to travel restrictions.
  • 6:48 - 6:50
    Humans are social animals,
  • 6:50 - 6:53
    and they resist when you try
    to hold them into place
  • 6:53 - 6:54
    and when you try to separate them.
  • 6:55 - 7:01
    We saw in the Ebola outbreak that as soon
    as you put a quarantine in place,
  • 7:01 - 7:03
    people start trying to evade it.
  • 7:03 - 7:07
    Individual patients, if they know
    there's a strict quarantine protocol,
  • 7:07 - 7:09
    may not go for health care,
  • 7:09 - 7:13
    because they're afraid of the medical
    system or they can't afford care
  • 7:13 - 7:16
    and they don't want to be separated
    from their family and friends.
  • 7:16 - 7:18
    Politicians, government officials,
  • 7:18 - 7:21
    when they know that they're
    going to get quarantined
  • 7:21 - 7:22
    if they talk about outbreaks and cases,
  • 7:22 - 7:27
    may conceal real information for fear
    of triggering a quarantine protocol.
  • 7:28 - 7:31
    And, of course, these kinds
    of evasions and dishonesty
  • 7:31 - 7:35
    are exactly what makes it so difficult
    to track a disease outbreak.
  • 7:37 - 7:41
    We can get better at quarantines
    and travel restrictions, and we should,
  • 7:41 - 7:44
    but they're not our only option,
    and they're not our best option
  • 7:44 - 7:46
    for dealing with these situations.
  • 7:47 - 7:52
    The real way for the long haul
    to make outbreaks less serious
  • 7:52 - 7:55
    is to build the global health system
  • 7:55 - 8:00
    to support core health care functions
    in every country in the world
  • 8:00 - 8:02
    so that all countries, even poor ones,
  • 8:02 - 8:07
    are able to rapidly identify and treat
    new infectious diseases as they emerge.
  • 8:08 - 8:13
    China's taken a lot of criticism
    for its response to COVID-19.
  • 8:13 - 8:17
    But the fact is, what if COVID-19
    had emerged in Chad,
  • 8:18 - 8:21
    which has three and a half doctors
    for every hundred thousand people?
  • 8:22 - 8:25
    What if it had emerged
    in the Democratic Republic of the Congo,
  • 8:25 - 8:29
    which just released its last
    Ebola patient from treatment?
  • 8:29 - 8:32
    The truth is, countries like this
    don't have the resources
  • 8:32 - 8:34
    to respond to an infectious disease --
  • 8:34 - 8:37
    not to treat people
    and not to report on it fast enough
  • 8:37 - 8:39
    to help the rest of the world.
  • 8:41 - 8:46
    I led an evaluation of Ebola
    treatment centers in Sierra Leone,
  • 8:46 - 8:49
    and the fact is that
    local doctors in Sierra Leone
  • 8:49 - 8:52
    identified the Ebola crisis very quickly,
  • 8:52 - 8:55
    first as a dangerous
    contagious hemorrhagic virus
  • 8:55 - 8:57
    and then as Ebola itself.
  • 8:57 - 9:02
    But, having identified it,
    they didn't have the resources to respond.
  • 9:02 - 9:05
    They didn't have enough doctors,
    they didn't have enough hospital beds,
  • 9:05 - 9:08
    and they didn't have enough information
    about how to treat Ebola
  • 9:08 - 9:10
    or how to implement infection control.
  • 9:11 - 9:16
    Eleven doctors died
    in Sierra Leone of Ebola.
  • 9:16 - 9:19
    The country only had 120
    when the crisis started.
  • 9:20 - 9:21
    By way of contrast,
  • 9:21 - 9:25
    Dallas Baylor Medical Center has
    more than a thousand physicians on staff.
  • 9:27 - 9:29
    These are the kinds
    of inequities that kill people.
  • 9:29 - 9:32
    First, they kill the poor people
    when the outbreaks start,
  • 9:32 - 9:35
    and then they kill people
    all over the world
  • 9:35 - 9:36
    when the outbreaks spread.
  • 9:37 - 9:39
    If we really want to slow down
    these outbreaks
  • 9:39 - 9:41
    and minimize their impact,
  • 9:41 - 9:44
    we need to make sure
    that every country in the world
  • 9:44 - 9:47
    has the capacity to identify new diseases,
  • 9:47 - 9:48
    treat them
  • 9:48 - 9:51
    and report about them so
    they can share information.
  • 9:52 - 9:56
    COVID-19 is going to be
    a huge burden on health systems.
  • 9:57 - 10:00
    COVID-19 has also revealed
    some real weaknesses
  • 10:00 - 10:02
    in our global health supply chains.
  • 10:02 - 10:07
    Just-in-time-ordering, lean systems
    are great when things are going well,
  • 10:07 - 10:11
    but in a time of crisis, what it means is
    we don't have any reserves.
  • 10:11 - 10:14
    If a hospital -- or a country --
  • 10:14 - 10:17
    runs out of face masks
    or personal protective equipment,
  • 10:18 - 10:21
    there's no big warehouse full of boxes
    that we can go to to get more.
  • 10:21 - 10:23
    You have to order more from the supplier,
  • 10:23 - 10:27
    you have to wait for them to produce it,
    and you have to wait for them to ship it,
  • 10:27 - 10:28
    generally, from China.
  • 10:28 - 10:33
    That's a time lag at a time
    when it's most important to move quickly.
  • 10:33 - 10:37
    If we'd been perfectly
    prepared for COVID-19,
  • 10:37 - 10:41
    China would have identified
    the outbreak faster.
  • 10:41 - 10:45
    They would have been ready
    to provide care to infected people
  • 10:45 - 10:47
    without having to build new buildings.
  • 10:47 - 10:50
    They would have shared
    honest information with citizens
  • 10:50 - 10:53
    so that we didn't see these
    crazy rumors spreading
  • 10:53 - 10:55
    on social media in China.
  • 10:55 - 10:58
    And they would have shared information
    with global health authorities
  • 10:58 - 11:01
    so that they could start reporting
    to national health systems
  • 11:01 - 11:03
    and getting ready
    for when the virus spread.
  • 11:04 - 11:07
    National health systems would then
    have been able to stockpile
  • 11:07 - 11:09
    the protective equipment they needed
  • 11:09 - 11:13
    and train health care providers
    on treatment and infection control.
  • 11:13 - 11:17
    We'd have science-based protocols
    for what to do when things happen,
  • 11:17 - 11:19
    like cruise ships have infected patients.
  • 11:20 - 11:24
    And we'd have real information
    going out to people everywhere,
  • 11:24 - 11:28
    so we wouldn't see embarrassing,
    shameful incidents of xenophobia,
  • 11:28 - 11:33
    like Asian-looking people getting attacked
    on the street in Philadelphia.
  • 11:33 - 11:35
    But even with all of that in place,
  • 11:35 - 11:38
    we would still have outbreaks.
  • 11:39 - 11:42
    The choices we're making about
    how we occupy this planet
  • 11:42 - 11:43
    make that inevitable.
  • 11:44 - 11:48
    As far as we have an expert consensus
    on COVID-19, it's this:
  • 11:49 - 11:51
    here in the US, and globally,
  • 11:51 - 11:54
    it's going to get worse
    before it gets better.
  • 11:54 - 11:59
    We're seeing cases of human transmission
    that aren't from returning travel,
  • 11:59 - 12:01
    that are just happening in the community,
  • 12:01 - 12:03
    and we're seeing people
    infected with COVID-19
  • 12:03 - 12:07
    when we don't even know
    where the infection came from.
  • 12:07 - 12:09
    Those are signs of an outbreak
    that's getting worse,
  • 12:09 - 12:12
    not an outbreak that's under control.
  • 12:14 - 12:17
    It's depressing, but it's not surprising.
  • 12:18 - 12:19
    Global health experts,
  • 12:19 - 12:22
    when they talk about
    the scenario of new viruses,
  • 12:22 - 12:25
    this is one of the scenarios
    that they look at.
  • 12:25 - 12:28
    We all hoped we'd get off easy,
  • 12:28 - 12:31
    but when experts
    talk about viral planning,
  • 12:31 - 12:35
    this is the kind of situation and the way
    they expect the virus to move.
  • 12:37 - 12:40
    I want to close here
    with some personal advice.
  • 12:41 - 12:42
    Wash your hands.
  • 12:42 - 12:45
    Wash your hands a lot.
  • 12:45 - 12:48
    I know you already wash your hands a lot
    because you're not disgusting,
  • 12:48 - 12:50
    but wash your hands even more.
  • 12:50 - 12:54
    Set up cues and routines in your life
    to get you to wash your hands.
  • 12:54 - 12:57
    Wash your hands every time
    you enter and leave a building.
  • 12:57 - 13:01
    Wash your hands when you go into a meeting
    and when you come out of a meeting.
  • 13:01 - 13:03
    Get rituals that are based
    around handwashing.
  • 13:04 - 13:06
    Sanitize your phone.
  • 13:06 - 13:10
    You touch that phone with your dirty,
    unwashed hands all the time.
  • 13:10 - 13:12
    I know you take it
    into the bathroom with you.
  • 13:12 - 13:14
    (Laughter)
  • 13:15 - 13:20
    So sanitize your phone and consider
    not using it as often in public.
  • 13:20 - 13:23
    Maybe TikTok and Instagram
    can be home things only.
  • 13:25 - 13:26
    Don't touch your face.
  • 13:27 - 13:29
    Don't rub your eyes.
  • 13:29 - 13:30
    Don't bite your fingernails.
  • 13:30 - 13:32
    Don't wipe your nose
    on the back of your hand.
  • 13:32 - 13:34
    I mean, don't do that anyway
    because, gross.
  • 13:34 - 13:36
    (Laughter)
  • 13:36 - 13:38
    Don't wear a face mask.
  • 13:38 - 13:41
    Face masks are for sick people
    and health care providers.
  • 13:41 - 13:45
    If you're sick, your face mask
    holds in all your coughing and sneezing
  • 13:45 - 13:48
    and protects the people around you,
  • 13:48 - 13:49
    and if you're a health care provider,
  • 13:49 - 13:52
    your face mask is one tool
    in a set of tools
  • 13:52 - 13:54
    called personal protective equipment
  • 13:54 - 13:57
    that you're trained to use
    so that you can give patient care
  • 13:57 - 13:58
    and not get sick yourself.
  • 13:58 - 14:01
    If you're a regular healthy person
    wearing a face mask,
  • 14:01 - 14:04
    it's just making your face sweaty.
  • 14:04 - 14:05
    (Laughter)
  • 14:05 - 14:07
    Leave the face masks in stores
  • 14:07 - 14:10
    for the doctors and the nurses
    and the sick people.
  • 14:11 - 14:14
    If you think you have
    symptoms of COVID-19,
  • 14:14 - 14:16
    stay home, call your doctor for advice.
  • 14:17 - 14:23
    If you're diagnosed with COVID-19,
    remember it's generally very mild.
  • 14:23 - 14:24
    And if you're a smoker,
  • 14:24 - 14:27
    right now is the best
    possible time to quit smoking.
  • 14:28 - 14:29
    I mean, if you're a smoker,
  • 14:29 - 14:32
    right now is always the best
    possible time to quit smoking,
  • 14:32 - 14:35
    but if you're a smoker
    and you're worried about COVID-19,
  • 14:35 - 14:39
    I guarantee that quitting
    is absolutely the best thing you can do
  • 14:39 - 14:43
    to protect yourself
    from the worst impacts of COVID-19.
  • 14:45 - 14:47
    COVID-19 is scary stuff,
  • 14:47 - 14:52
    at a time when pretty much all of our news
    feels like scary stuff.
  • 14:52 - 14:57
    And there's a lot of bad-but-appealing
    options for dealing with it:
  • 14:57 - 15:02
    panic, xenophobia,
    agoraphobia, authoritarianism,
  • 15:02 - 15:07
    oversimplified lies that make us think
    that hate and fury and loneliness
  • 15:07 - 15:09
    are the solution to outbreaks.
  • 15:09 - 15:11
    But they're not.
  • 15:11 - 15:13
    They just make us less prepared.
  • 15:13 - 15:18
    There's also a boring
    but useful set of options
  • 15:18 - 15:20
    that we can use in response to outbreaks,
  • 15:20 - 15:24
    things like improving health care
    here and everywhere;
  • 15:24 - 15:27
    investing in health infrastructure
    and disease surveillance
  • 15:27 - 15:29
    so that we know
    when the new diseases come;
  • 15:29 - 15:32
    building health systems
    all over the world;
  • 15:32 - 15:37
    looking at strengthening our supply chains
    so they're ready for emergencies
  • 15:37 - 15:39
    and better education,
  • 15:39 - 15:44
    so we're capable of talking about disease
    outbreaks and the mathematics of risk
  • 15:44 - 15:46
    without just blind panic.
  • 15:47 - 15:49
    We need to be guided by equity here,
  • 15:49 - 15:51
    because in this situation, like so many,
  • 15:51 - 15:55
    equity is actually
    in our own self-interest.
  • 15:56 - 15:58
    So thank you so much
    for listening to me today,
  • 15:58 - 16:00
    and can I be the first one to tell you:
  • 16:00 - 16:03
    wash your hands
    when you leave the theater.
  • 16:03 - 16:05
    (Applause)
