In season 1 of the zombie show, The Walking Dead, TS-19, I think the episode was called, Rick and his band of merry survivors were at the CDC and were told that they were all infected, well, at least the leader Rick was told. It was enough to make him hit the booze, as I would. However, an Oxford study that around half of the UK population is infected has been interpreted as indicating that the corona bug is not so bad after all:

“Because testing regimens across the world have varied tremendously, the actual mortality and hospitalization rates of COVID-19 have been hard to pin down. But modeling by researchers at the University of Oxford could provide some welcome good news, even if the initial takeaway doesn’t seem so promising. According to hypothetical modeling from Oxford’s Evolutionary Ecology of Infectious Disease lab, half of the population of the United Kingdom may have already been infected with the coronavirus. If this modeling is confirmed in follow-up studies, that a minuscule number of those infected require hospital treatment, with a majority showing very minor symptoms, or none at all. In the mathematical experiment, the researchers looked at the population who are at risk of a severe infection. While a risk rate of 0.1 percent suggested a high number of infected people — suggesting lower hospitalization and mortality rates — a higher risk rate of 1 percent implied the possibility of a more threatening virus at the population level. In the following chart, ρ represents the risk rate, with the dramatic yellow line representing the possibility of a majority of the U.K. population infected.”
