Attitudes like yours are why it kept spreading instead of petering out. I'm not saying that people need to get vaccinated, but I'm god damn sick of people not caring about spreading disease, whether vaccinated, or not. Humanity, as a whole, is in a war with disease. We don't need collaborators. All it takes for evil to triumph is for good people to do nothing.

> Healthy, young people who were intentionally exposed to the coronavirus SARS-CoV-2 developed mild symptoms — if any — in a first-of-its-kind COVID-19 human-challenge study.
That doesn't mean they weren't contagious.
> The first participants received a very low dose — roughly equivalent to the amount of virus in a single droplet of nasal fluid — of a virus strain that circulated in the United Kingdom in early 2020. Researchers anticipated that a higher dose would be needed to infect a majority of participants, says Andrew Catchpole, chief scientific officer of hVIVO. But the starting dose successfully infected more than half of the participants.
> The virus replicated incredibly rapidly in those who became infected. On average, people developed their first symptoms and tested positive, using sensitive PCR tests, less than two days after exposure, on average. That contrasts with the roughly five-day ‘incubation period’ that real-world epidemiological studies have documented between a probable exposure and symptoms. High viral levels persisted for an average of 9 days, and up to 12 days.
