A clear and simple visual story on how COVID-19 spreads and kills -- and how we will beat it. In the spirit of Sun-Tzu's "Know your enemy," we chose to tell the story from the point of view of the virus.
Written by a bestselling author, a disease scientist PhD, and an award-winning cartoonist, this story gives a renewed sense of perspective. Writing this helped us see what to do next, and even gave us a bit of needed calm.
We hope this story does the same for you.

Karl Malamud-Roam, & Lloyd Dangle
2. 2
Know your enemy
and know yourself;
in a hundred
battles you will
never be in peril.
- Sun Tzu, The Art of War
3. We put this story together to help
ourselves better understand COVID-19 in
a super-accessible way. Maybe our story
can help you better understand it too.
3
Like many of you, weâre pretty freaked out
about the rapid spread of Corona Virus
COVID-19. And for us, we find one of the
best ways to stay sane is to get to work.
So as healthcare heroes are saving patients,
virologists are working on vaccines, and
public health teams are tackling everything
else, we decided to do what we do best:
Letâs try to tell a well-informed visual story.
A quick note from Dan, Karl, & Lloyd:
The story we chose to tell is from the virusâs
own point of view. Itâs not a story weâve
seen told yet, and we thought that knowing
what our enemy is up to is the best way to
defend against it.
Getting to know the virus has given us a
renewed sense of perspective, helped us see
what makes sense to do now and why, and
even given us a bit of needed calm.
We hope this story does the
same for you.
A note on the science: We based
everything here on published
sources and provide a list of
sources at the end. If we got
anything wrong, please let us
know â and send your sources so
we can make valid corrections!
We plan to update this as new information
comes in; updates will be posted on
slideshare.net
Also, we know a virion doesnât
have eyes and a mouth âş. Weâve
chosen to represent COVID-19
this way so that we can more
easily understand how it works
and what it is trying to do.

5. The Story
Unfolding
Today
- Part 1 - â Meet VIC the Virus
â What Vic does
â How Vic kills
â How dangerous Vic is
â Why the Pros are so
scared of Vic
â Some good things to
do now to be safe
6. Iâm Vic the Virus. You people call me Covid-19.
Iâm a new member of the
âcorona virusâ
family, and a pretty simple
one, at that.
Iâve got some code (RNA)
inside a protective coat
(made of protein), and a
key (a chemical sensor also
made of protein). Thatâs
about it.
My job, like all organisms, is
to pass my genetic
code to my kids and send
them out into the world.
Sounds simple, right? Well, it
isnât.
6
Call me Vic.
Years ago, they named my family of
viruses âCoronaâ because in
early microscope images our
sensors sort of looked like a crown.
This is my PROTEIN COAT.
This key is one of my
ACE-2 receptor sensors.
Iâm lucky in that Iâm one of
the first to have this
special key. (Youâll see why
in a moment!)
This is my RNA CODE.
7. Iâm just trying to make my way through the world and do my job:
ensure my code keeps living and gets passed on to my kids.
But it isnât easy.
Three things make my life
tough:
First off, traveling is
tricky; I canât walk, I canât
swim, and I canât climb. What
I can do is âflyâ and cling to
things.
Second, I need a home
(my âhostâ) to live in. Out here
in the world Iâm fragile and
can die from almost anything:
heat, soap, drynessâŚ
Third, I canât make my
kids by myself. I need
my host to do that for me.
Itâs rough!
7
8. Lucky for me, youâre the perfect home!
When we meet, I hope you
let me in.
If you do, three things might
start to happen:
1) Infection
2) Illness
3) Immunity
But Iâm getting ahead of
myself; letâs take those one
at a timeâŚ
8
PAT
9. Because your nose, throat, and lungs are the perfect
host home for me, I would love to infect you!
The cells in your nose and
throat are a great place
for me to live. Iâm happy
there⌠and I can be so quiet
you might not even know Iâm
there.
But what I really want is to
get into your lung cells.
Theyâre like heaven for me.
Give me enough time in your
nose, and Iâll try to make my
way down to your lungs.
9
1) Infection
10. The reason youâre so perfect is because my key opens your cells!
Just what I needed!
With your help, hereâs what I do:
â I attach myself to the outside of
your cell.
â Guess what: Your cell wall* has an
ACE-2 lock (a specific
receptor)!
â Luckily for me, I have my ACE-2
key!** I open a little vestibule
into your cell wall.
â Because I have the right key, your
cell is happy to let me in.
10
* Scientists prefer to say âmembrane.â
** My cousin SARS also had an ACE-2 key,
and he killed a lot of people too!
My key fits your cellâs lock.
11. Iâm going to use your cell to make my kids.
when my genetic material enters your cell you donât even notice!
Leaving my coat at the door,
I shoot my RNA code into
your cell. Then I trick your
cell to make my RNA.
Inside your cell, thereâs a
bunch of your RNA.
Normally, your RNA tells your
ribosomes which
proteins to make.
But lucky for me, your
ribosomes can't tell your
RNA from mine!
11
My codeâŚ
hijacks your ribosomes!
12. And before long youâve made my kids for me!
So my RNA tells your ribosomes
to make more of ME!
First, my RNA tells your cells to
copy my RNA.
Next, your cell makes copies of my
protein coat.
Finally, your cell puts my RNA in
my new coats.
And now youâve made more of me!
Cool! I get your cells to make my
children, complete with their own
coats to protect our code.
12
Which then make
more of ME!
13. Then we all like to settle in and really make ourselves at home.
Most of my kids settle in the
neighborhood, entering cells in
your nose, throat, or lungs.
Eventually we take over big
chunks of the territory and
then start thinking about
moving on.
13
Weâre tired of
quarantine! Can
we go out now?
14. And then you send my kids out into the world for me!
Coughing sends my little babies
flying!
Even just exhaling could be
enough to send some out into
the world.
Now they can infect your whole
human family and keep my story
going!
14
PATâs Family, Friends,
colleagues, and even
random folks!
15. Thereâs just one problem with our deal. You might get ill.
Now hereâs the thing about us
viruses: although we love you,
your body doesnât love us.
15
2) Illness
16. Because I trigger your own defenses to react so strongly,
your own body might hurt you. Sorry.
Once Iâm inside you doing my work,
your cells might detect me.
If they do recognize that I donât
belong there, your body sends all
kinds of defenses to try and take
me out:
First, you cough to try to get
me out of your body.
Next, in order to lock me down and
keep me from spreading, your cells
tighten up and surround me with
fluid.
Thatâs called inflammationâŚ
and with me, thatâs likely to
backfire.
16
Your body inflames to try
to lock me down.
You cough to try to get me out.
17. In extreme cases, I might kill you. But itâs not just
me that does you in; itâs your own inflammation!
Remember, I love to live in your
lung cells.
But hereâs the problem for you:
when your lung cells become
inflamed, they canât do your
breathing anymore.
Your lungs fill with fluid, you get
pneumonia, and if it
spreads to both your lungsâŚ
well, you suffocate, your organs
fail, and you die.
WHICH MEANS Iâm mostly
dangerous to people with old or
weak lungs.
Sorry. It sucks for me and a lot
of my kids too.
17
When your lung fills with fluid,
you canât breathe.
18. But hereâs the thing, I donât kill everyone.
In fact, Iâm not as deadly as some other viruses.
18
Because many people will
get me, a lot of people are
likely to die.
If I infect you, you will
probably get really sick, but
you probably wonât die.

But I will kill a
lot more than
they did.
19. 5 reasons the Pros are so scared of meâŚ
Look, I might
not be the
deadliest virus
out there, but I
do have some
special traits
that freak
experts out:
19
1) Having the ACE-2 key means
I have a super easy time
infecting your lungs â which is
really dangerous to you.
3) Iâm so good at hiding inside you so
that you might not even know I'm there.
Which means nobody really knows how
contagious I am â and how many of you
are already infected.
4) My family is good at
mutating and adapting.
(More on that in Part 2)
5) Scariest of all is Iâm new,
unknown, and unpredictableâŚ
and youâre not testing fast
enough to know whoâs infected.
2) I spread much
more easily than my
deadlier cousins.
20. The super good news for you is that you have a lot of ways to avoid me.
20
Wash your hands a lot.
Plain old soap and water
literally melts my
protective coat!
Practice good social distance:
- Cough danger distance = 6 feet.
- Avoid groups.
- Stay home.
- Donât travel unless you really have to.
This is why governments are
quarantining; they are trying to
keep people from getting
infected!
Wearing a mask might help keep
me out of your mouth and nose
â which is my only way in.
21. If you spread me
to as many other
people as you can,
Iâll be happy.
But you wonât. Itâs easy to spread me around:
I fly well, cling to hard surfaces
like spiderman, and love it when
people put me directly into
their own mouths and noses.
Thatâs how Iâm growing my
family! I canât do it without
your help.
Remember, my job is to keep my
code going. If you spread me
around, you're helping me, but
not your friends and family!
21
You might be
tempted to hang out
with a lot of others;
just remember â
thatâs good for me.
(And you canât tell who has
me just by looking!)
22. - Part 2 -
The Story as
it might
progress in
the future
â How we might
develop immunity
â How Vic might
mutate
â Potential Vaccines
and drugs
â What you might
want to think
aboutâŚ
23. Normally, your body can figure out how to defeat me
with tools you already have. (Innate immunity)
23
3) Immunity Aside from inflammation, your body has
other built-in defenses:
⢠Interferons in your cell notice
my RNA, try to block it, and hang
signs outside the cell that it's
infected.
⢠Your killer T-cells then rush
through your body and destroy the
cells Iâve infected.
Together these try to stop my infection
before I cause serious damage, and for
most germs they work well.
But theyâre slow and they kill a lot of
your cells â and theyâre just not good
enough to stop me.
24. But if that doesnât work, you call in the Seal Team! (Acquired immunity)
24
Your better defense is acquired
immunity: your body develops it
when you recognize that Iâm a new
kind of bad guy.
You create specific antibodies
that are like Navy SEALS trained to
kill only me. Theyâre deadly to me but
they take time to create and train.
Itâs a race to get your SEALs
deployed before pneumonia kills you.
If you stay alive long enough to
develop antibodies, they recognize
me and stop me before I can get
into any more cells.
Now youâre immune and I canât
make you sick anymore.
Game over for me, man!
25. Hereâs the thing⌠just like in your family,
my children arenât all identical.
Knowing that your body wants
to recognize and kill me, I want
to make sure my children
arenât exactly like me.
I want them to be close
enough to live like I do, but I
also need my kids to mutate
just enough to stay ahead of
your defenses.
25
26. Hey, I canât control all the mutating. Sometimes I might mutate into a
Crazy Cousin whoâs really hard on you.
Sometimes the mutations in
my code get more extreme.
If one of my descendants
becomes a Crazy Cousin, you
never know what might
happen.
My crazy cousin MERS
popped up a few years ago
and killed over one-third of
the people that he infected.
But he was so deadly he killed
his hosts before they could
send out his children. He died
out, but so did about 800
people.
26
27. Vaccines are cool for you because they supercharge your antibodies.
Vaccines are great for you and
terrible for me!
They trick your body into making
antibodies without having to
get infected or sick!
That's not fair to me!
But it's hard to get them to kill
me and my cousins without
hurting you â and getting that
right takes time.
In any case, vaccines only work if
you people get them before you
get sick!
27
28. Drugs might slow or stop your illness if you are infected.
Drugs donât stop me from
infecting you, but they might
stop me from killing you⌠and
will probably make you recover
faster.
Bad news for you, there are no
proven drugs against me or my
Corona family.
But bad news for me, your
researchers are looking at
several that seem promising.
Very possibly, youâll have a safe
treatment available to you
before you have a vaccine.
28
29. Look guys, if you REALLY want to kill me and
protect yourselves, you canâŚ
29
Stay rational and believe
in science; you will build
a safe vaccine and find
effective treatments.
Stay kind and believe in
each other.
Stay away from
crowds and keep
your hands clean.
Remember: Youâre the
resilient ones! (Iâm
just a damn germ!!)
30. The most important thing is to be realistically positive!
30
The impact of the economic downturn
might be worse than the public health
effects⌠so letâs be thoughtful about
how we buckle down.
And once things have stabilized, and
they will, letâs be prepared to kick the
economy back into gear FAST.
Remember: This too shall pass.
Letâs be as realistic as we can (based on what
we know and think we know) about what that
means, and for how long it might take.
