What do moisture measurements tell us?

(Note:  This post was composed in March 2014 but somehow never got published) No environmental measurement is arguably more critical to understanding the indoor environmental factors relevant to the presence of fungi or the potential survival of infectious airborne agents than the moisture measurements. Characterization of the presence of moisture on surfaces, also known as …

Answer to the seasonal flu mystery? – Indoor environment-microbe interactions

The Virginia Tech group has published another paper looking at the impacts of indoor environmental conditions on microbes. In this case, it’s potentially a key clue to the on-going search for an explanation to the seasonality of influenza puzzle. It’s not just airborne humidity but also the droplet. composition that matter. Past efforts to find …

“Mechanisms by Which Ambient Humidity May Affect Viruses in Aerosols” new paper from Linsey Marr’s group

An interesting review article from Linsey Marr’s group at Virginia Tech looking at the various factors that might influence virion survival in aerosols.   Abstract below: Many airborne viruses have been shown to be sensitive to ambient humidity, yet the mechanisms responsible for this phenomenon remain elusive. We review multiple hypotheses, including water activity, surface inactivation, …
