One of the recurring themes of this blog is how much we still have to learn about the influenza virus, and how it is spread. Amazingly, even in 2011, many of the basic questions about influenza are still unanswered.
How long do flu viruses remain airborne?
How far can a flu virus travel in the air?
Do surgical masks or N95 protect the wearer?
What are the relative values of hand washing, mask wearing, and social distancing during a pandemic?
We’ve seen a number of studies over the years that have provided partial – and sometimes conflicting – answers. But solid scientific data on which to base recommendations remains scant.
From NTDTV, we get a report today on one Singapore research study’s attempt to quantify how far viruses may travel via coughs and sneezes.
This brief report includes an English Language 2min 30sec minute video with interviews with virologist Dr. Julian Tang and slo-mo film clips of sneezes.
Probably best to wait until you’ve finished breakfast to watch it.
As this study is planned to run until mid-2012, results won’t be going viral anytime soon.
