Their updated estimate is similar to ones from Iceland (mass testing) and others. More people than expected go trough the disease without symptoms. At least 50%.

The math goes as follows:

- 60% need to be infected for herd immunity.

- At least 50% of infected show no symptoms.

- CFR is 0.7%.

0.6×0.5×0.007 = 0.002

(This math assumes that everyone without symptoms is a diagnosed case, so overestimte)
