In April, preliminary results from the modelling made by a Finnish research consortium supported the idea of small aerosol emissions created by a coughing person to be spread and to be retained in a public space.
In the last week of May, the hypothesis was confirmed, and the study was released and entitled “Modelling confirms: Isolating the ill and prioritizing remote work are key strategies in combating the coronavirus”.

The joint project is conducted by a consortium led by Aalto University Assistant Professor Ville Vuorinen, involving around 30 researchers, with specializations in fluid dynamics, aerosol physics, social networks, ventilation, virology and biomedical engineering. The research is being carried out in conjunction with ESSOTE (the joint municipal authority for social and health services in South Savo), which proposed the research project. The main participants include:

In April and May, Environics has conducted a mutual ENVI BioScout study with ESSOTE, focusing to the presence and possible airborne transmission of SARS-CoV-2 in indoor spaces at the Mikkeli Central Hospital. We are currently analyzing the first set of the real-time ENVI BioScout measurement data, and the collected secondary air samples are under biological analysis.
