Low doses of SARS seem to have much lower mortality: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3367618/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3367618/ Of the 79 infected, 19 died. E block (where the index patient was), had 53 infections and 15 deaths for a mortality rate of 28%. Other units had 26 infections and 4 deaths, for a mortality rate of 15%. The death rate of patients in E7 (closest to the index patient and with the highest viral load) was 70%. That's more than 4x difference in mortality based on viral load! It would be very surprising if low doses of SARS-CoV-2 caused higher mortality. Therefore should allow researchers and volunteers to experiment with low dose deliberate infection. It could save hundreds of thousands of lives.
