Which is the role of the skin in the transmission of the coronavirus? In this video, Marc Domingo, PhD Researcher at the Soft Matter Theory Group at ICMAB, shares with us some of the simulation work he has done trying to elucidate the interactions that may occur between the skin and the coronavirus.
The transmission of respiratory viruses in general (including coronaviruses and SARS-CoV-2 in particular) involves the expiratory emission of virus-containing aerosols and droplets which may infect other individuals via direct or indirect mechanisms. The possibility of contamination of human skin by infectious virions might play an important role in indirect transmission of respiratory viruses but little is known about the fundamental physico-chemical aspects of the virus-skin interactions.

In this video we show all-atom simulations between the spike SARS-CoV-2 glycoprotein and two models of skin, made with Visual Molecular Dynamics (VMD) from computer simulations performed with the software Nanoscale Molecular Dynamics (NAMD) at the Centro de Supercomputación de Galicia (CESGA).
The video also explores what type of information we can obtain from research based in theoretical simulations, as well as some of its shortcomings.
