Exploring why some COVID-19 patients lose their sense of smell.

[2greys]

Doctors have reported that partial or total loss of the sense of smell is often an early symptom of infection with SARS-CoV-2, the virus that causes COVID-19. Now, researchers reporting in ACS Chemical Neuroscience have shown that in mice, two proteins required for SARS-CoV-2 entry are produced by cells of the nasal cavity that contribute to odor detection. Moreover, larger amounts of the proteins are made in older animals than in younger ones..............................If also true in humans, this result could explain why older people are more susceptible to SARS-CoV-2, the researchers say.

I lost my sense of both smell and of taste when I was first investigated for bronchiectasis, about 10 years ago, so there must be a link with BX and Covid-19, 2G. For me these were the first indicators of my diagnosis at the time, which scans confirmed . Thanks for the article.
