Top Event
• There are only 2 threats leading you to catching Covid-19: via airborne transfer of the virus, or
from direct contact with infected surfaces and then touching your face and infection via eyes,

o your death or
o the death of someone you infect
o a protracted lockdown
And the Top Event, when things start to go wrong, is when you become infected.
