The nose – the entry point for COVID-19?

Researchers have found that there are two types of cells inside the nose that are the likely entry point for the COVID-19 virus. These cells work as “viral entry receptors” and are highly accessible to the coronavirus because of the location in the nose. (Sungnak et al. 2020)

This developed the idea of a nasal protection device that could reduce the exposure to viruses.

In 2021, NOSA launched NOSA Microbial Control – a medical device designed to reduce your exposure to viruses when you breathe in through your nose.

Tests by external laboratories have shown that NOSA Microbial Control can reduce up to 93% of Coronavirus, Rhinovirus and Norovirus when in contact with the device. A reduced exposure to viruses has been shown to reduce the risk of respiratory infections.
