During the COVID-19 crisis, the Czech Republic has experienced shortages of protective equipment (masks and respirators). What little was available was saved for the most vulnerable workers - doctors, nurses, social workers etc.
On March 14 (two weeks since the first confirmed case), a speaker, writer and social media influencer Petr Ludwig made an educational video on the importance of wearing masks, not as a protection for yourself but to protect others in case you are unaware of being sick and are not showing symptoms. The video cites a study by researchers from University of Cambridge which concludes that surgical masks are 3x more effective than home-made masks, nevertheless they recommend home-made masks as a last resort when surgical masks are not available. As of March 22, the video had 560k views and was shared and promoted by many other Czech influencers.
As the shortage of masks provided by the government continued, hospitals reached out on social media and asked if people may be able to sew a few masks for them because they were running low. In an unprecedented show of support, many people started making masks, not just for the hospitals but for everybody. The effort was both individual - people making masks by hand sewing or on a sewing machine at home, and organizational - theaters, non-profit organizations, small business and factories which normally produce clothes, linens, accessories redirected their efforts into full-time sewing. Local companies were sewing in bulk, supplying hospitals, senior citizen homes, the police or firemen. Masks were delivered to hospitals or to friends and neighbors who would often find them in their mailboxes. In some areas, people created “mask trees” where they would put available extra masks that were up for grabs for others.
