This is incorrect. There was a paper recently where they determined that covid directly cleaves your smell receptors from inside your nose. They will grow back eventually. This is reassuring, because initially they thought that covid may be directly attacking the brain's ability to process smell. However, this is not the case. Zinc deficiency has been identified as correlated with severe covid symptoms, but it's not the reason for loss of smell in covid cases. The covid deniers make me shake my head. Do you know how stupid you look? We have sequenced a brand new virus. The data is out there in the open if you know how to read it. The sequencing is on Github FFS! Now, whether you believe in the politicization of covid is another matter. But denying that there is no virus called covid-19 just makes you look like an ignorant fool.
