    I live in Madrid, Spain in an area that has been a hotbed for SARS-CoV-2 contagion. I have kept confined all this time, but my girlfriend has to go to work, so I am not isolated.
    I have only had one real symptom: 2 days complete anosmia. I couldn’t even smell vips vaporub with my nose inside the jar. I normally have a keen sense of smell and this was a very weird experience. After two days of sudden and total blackout (I smell my coffee every morning and one day it wasn’t there), I got back to maybe 50% and then gradually up to (3 weeks later) maybe 80%. I don’t know what I had since I don’t have access to a test of any kind. In any case I thought you’d find this interesting.

    I love all your podcasts (specially TWIV). Keep on the good work.

    Reminds me a bit of what I tend to study pathogenic fungi and ameoba! They often cause loss of smell before showing CNS symptoms as the enter through nasal epithelium or smell fibers
