Since the emergence of the novel Sars-Cov2 virus that causes Covid-19, new symptoms are reported everyday. one of these symptoms that are common among Covid-19 patients is the sudden loss of smell, or anosmia.
It hasn’t been clear as if it’s caused by through neurological etiology. A new research highlights that the virus causes loss of smell through its infection to nonneuronal cells in forebrain, and nasal supporting cells.
Their finding suggests that olfactory neurons aren’t affected as they don’t express ACE2 receptor, the virus known mode of transmission.
This study opens the scope for better understanding how the novel coronavirus affect patients, and how to better combat it.
