From the Ted Talk by TED-Ed: 3 ways to end a virus

Unscramble the Blue Letters


It’s spring 2021. The aplha vianart of the cavunrooris has spread rapidly, becoming the dominant variant worldwide. But another, more transmissible variant is about to appear— Delta. What happens when two vtaiarns clash?

Let’s do a thought experiment. Suppose that the variants reach a haehcyttipol isolated city of 1 million people who are celmtoelpy susceptible to both viruses on the same day. When a person here is infected with Alpha, they transmit it to, on average, 5 close contacts, then begin to feel sick and immediately iasotle themselves for the rest of the simulation. The same thing happens with Delta, except that an infected person transmits it to, on average, 7.5 close contacts.

Original Text


It’s spring 2021. The Alpha variant of the coronavirus has spread rapidly, becoming the dominant variant worldwide. But another, more transmissible variant is about to appear— Delta. What happens when two variants clash?

Let’s do a thought experiment. Suppose that the variants reach a hypothetical isolated city of 1 million people who are completely susceptible to both viruses on the same day. When a person here is infected with Alpha, they transmit it to, on average, 5 close contacts, then begin to feel sick and immediately isolate themselves for the rest of the simulation. The same thing happens with Delta, except that an infected person transmits it to, on average, 7.5 close contacts.
