The corona virus disease COVID-19 has changed the world. To combat the pandemic, researchers and companies around the world are working to develop vaccines and medicines. Chitosan also has potential in the area of vaccine development and functionalization of protective equipment such as respirators. We have prepared summaries of recent publications on chitosan as an aid in the fight against corona.

In the current corona pandemic, the protection of medical personnel who have contact with Covid-19 infected patients is important, also to ensure stability of the health care services. The personal protective equipment of hospital staff includes particle filtering respiratory masks. From early 2021, a clinical study will be conducted to investigate the protective effect of a new type of respirator with a filter element containing chitosan nanoparticles in Brazil. More about this study and other current clinical studies with chitosan in this article.

What about the viral safety of chitosan? Here, we would like to present an interesting publication about the viral safety of chitosan. Chitosan can be applied as a virus-free biopolymer for medical products in human, as the deacetylation process of chitin is sufficient for virus inactivation, shown by Park et al (2015). The researchers from Korea used chitin from Heppe Medical Chitosan to show that viruses are efficiently inactivated during the deacetylation process from chitin to chitosan.

The corona virus disease COVID-19 has changed the world since early 2020 in many ways. To combat the pandemic, researchers and companies around the world develop vaccines and medicines. Chitosan has potential in the area of vaccine development and functionalization of protective equipment such as respirators. We prepared reviews of recent publications about chitosan in the fight against corona.
