MedicalResearch.com Interview with: Dr. Ajit Ahlawat (en.) Scientific staff (Post-Doc), Department Experimental Aerosol & Cloud Microphysics Leibniz Institute for Tropospheric Research (TROPOS) MedicalResearch.com: What is the background for this study?   Response: World Health Organization (WHO) has recently acknowledged that novel coronavirus (COVID-19) can be transmitted via aerosols after an appeal from 239 scientists from 32 countries including the chemist Prof. Hartmut Herrmann from our institute i.e. TROPOS. In order to contain the spread via the aerosol particles floating in the air, the researchers recommend not only continuing to wear masks but also, and above all, good indoor ventilation. In aerosol research, it has been long known that air humidity plays a major role i.e. either at high humidity, more water adheres to the particles and so they can grow faster or at low humidity, evaporation occurs and particle will lose its water content. So, we were curious about what types of studies have already been conducted on this topic and how indoor relative humidity (RH) will influence SARS-CoV-2 airborne transmission in indoor environments.
