I found this article which makes that claim, and cites the WHO joint mission report. However, I can’t find the claim (or the number “25%” used in any capacity) in the cited document at all. I suspect that the article mixed up percent of cases which are asymptomatic with the percent of transmissions which are from asymptomatic sources.
