I have made an evidence-based video about the importance of wearing masks (even homemade) for important prevention of the spread of coronavirus Covid-19 in society. Please share and help to spread the key message that can save lives and slow the pandemic.
We have tested the hypothesis in Czech technical universities, and it worked. Now it is obligatory to wear masks in the whole country. I'm part of the advisory team COVID-CZECH that consists of a virologist, epidemiologist, doctors with specialization in population protection, chemists, and physicist with specialization if filtration. This group is an advisory expert group of our government in Prague.

Scientific Studies
- "We conclude that population-wide use of face masks could make an important contribution in delaying an influenza pandemic. Mask use also reduces the reproduction number, possibly even to levels sufficient for containing an influenza outbreak." Brienen, Nicole CJ, et al. "The effect of mask use on the spread of influenza during a pandemic." Risk Analysis: An International Journal 30.8 (2010): 1210-1218."
- "Any type of general mask use is likely to decrease viral exposure and infection risk on a population level, in spite of imperfect fit and imperfect adherence, personal respirators providing most protection." - van der Sande, M., Teunis, P., & Sabel, R. (2008). Professional and home-made face masks reduce exposure to respiratory infections among the general population. PLoS One, 3(7).
- "However, during a severe pandemic when use of face masks might be greater, pandemic transmission in households could be reduced." MacIntyre, C. R., Cauchemez, S., Dwyer, D. E., Seale, H., Cheung, P., Browne, G., ... & Ferguson, N. (2009). Face mask use and control of respiratory virus transmission in households. Emerging infectious diseases, 15(2), 233.
