The ratio of undetected asymptomatic COVID-19 cases to confirmed cases is high.

the verdict
REFUTED
the evidence says no
Recorded sources
0 sources for · 2 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that the ratio of undetected asymptomatic COVID-19 cases to confirmed cases is high?

No. The available scientific evidence items that estimate the proportion or ratio of undetected asymptomatic COVID-19 cases indicate that these numbers are relatively low compared to total or confirmed cases, refuting the claim that the ratio is high.
