“We all know how things go viral on the Internet. You see something funny. A cat video, and you share it with 10 people, and those people share it with 10 people each, so you’re up to 100. And those 100 share it to another 10, so you’re up to 1,000. They keep sharing, and 1,000 becomes 10,000 and then 100,000 and then 1 million. So in only six cycles of transmission, one person can affect one million. Real viruses, like the new coronavirus, work exactly the same way.”
– Dr. John Abikhaled, Travis County (Texas) Medical Society, explaining the cycle of COVID-19 transmission.
