Spontaneous mutations mean that a virus can become more infectious by bad luck alone. We were unlucky.

- naasking 4y agoThe virus becoming more infectious over time is exactly my point. That's typical. What's not typical is the virus already being so infectious right from the start. Normally a zoonotic transfer circulates poorly in the human population before it mutates to become more infectious for the host. COVID-19 was already excellent at infecting humans from the earliest points we've found. That's very, very unusual.
