"However, when taking quality into account, and only analysing those sero surveys that had a low risk of bias, it is interesting to note that the inferred IFR rises substantially to 0.76% (0.37-1.15%). This may be due to the bias in lower-quality serosurveys being towards a higher prevalence (30), which in turn lowers the IFR substantially."

"the data we have so far indicate that the crude mortality ratio (the number of reported deaths divided by the reported cases) is between 3-4%, the infection mortality rate (the number of reported deaths divided by the number of infections) will be lower."

DONATIONS:
If you'd like to support this channel, please don't send money to me. My videos are free and my channel isn't monetized, so if you'd like to donate and encourage me to spend the time and effort it takes to check all this information, please send money to a charity I endorse, listed in the video description. Thanks.
The charity I strongly endorse is called Health in Harmony. It funds a hospital in Borneo that provides affordable health care to villages on the edge of a national park in return for a pledge not to cut down trees. The pledges are monitored, and the result has been a dramatic decrease in deforestation rates and an increase in the health of the local population.
Thanks to your generous contributions, the founders are spreading the idea to other countries, like Madagascar.
See psmag.com/social-justice/save-the-trees-well-save-your-life-46121 for an explanation of their work.
