Covid-19. The loss of smell, or anosmia, combined with the loss of taste can last for several weeks if you have contracted the virus.

Loss of smell, or anosmia, combined with loss of taste can last for several weeks if you have contracted the virus. In a July 24 study, researchers at Harvard Medical University demonstrated that this was the result of how SARS-CoV-2 entered our body, as you can find out in the video at the top of this article.

Science Advances was to confirm one or the other of the hypotheses, to better understand how the virus enters the human host. “data-reactid =” 14 “> Anosmia can come from a local cause (the nasal cavity where locates the olfactory) or cerebral mucosa: the brain, under the effect of an imbalance, can indeed lead to a loss of smell. One of the objectives of the study published in the journal Science Advances was to confirm one or the other, to better understand how the virus enters the human host.

ACE 2 receiver. Component of several types of cells, such as stem cells and blood vessels, its role in our body is complex and essential. But it provides the coronavirus with a real “gateway” to enter our body. “data-reactid =” 15 “> The result of the study is undoubtedly: SARS-CoV-2 does infect the respiratory cavity, via an enzyme whose role researchers have long suspected: the ACE 2 receptor. of several types of cells, such as stem cells and blood vessels, its role in our body is complex and essential, but it provides the coronavirus with a real “gateway” to enter our body.

The ACE2 receptor, outside the cell, allows the virus to attach itself to it, and open the cell to infect it. It is then that our sense of smell is disrupted, and with it that of taste. For the researchers, this is confirmation that our airways are not only where the virus is concentrated, but also that it does not normally infect neurons: good news, because the brain damage can then be much more severe. .
