Time of onset and duration of post-COVID-19 acute telogen effluvium
Data was gathered from 30 patients from March to July 2020 who reported intense hair shedding following a positive COVID-19 diagnosis, as denoted by positive PCR. TE initiated a median of 45 days (IQR=13) after RT-PCR positive test. Among patients that had TE resolved by July 31st (n=20), resolution occurred in a median of 33 days after onset. Among patients with ongoing TE by July 31st (n=10), median duration was at least 35 days, range 30-81 days. In sum, "COVID effluvium" appears to occur sooner and have a shorter duration than TE associated with other triggering events.
