Anti-epidemic masks as we know them today were invented in
more than a century ago,
during the Chinese state’s first effort to contain an epidemic by biomedical
means. When the plague struck the northeastern provinces of the China in the
autumn of 1910, the Chinese authorities broke with their longstanding
opposition to Western medicine: They appointed Wu Lien-teh (also known as Wu
Liande), a young and brilliant Cambridge-educated Chinese doctor from British
Malaya, to oversee efforts to stem the outbreak. The plague that was killing at
least 1 in 3 was about to meet its match. China
Soon after arriving in the field, Wu asserted that this plague wasn’t being spread by rats, as had been assumed, but was airborne. The statement was heresy, and turned out to be correct. Wu proved his point by adapting existing surgeons’ masks — which were made of a cotton wad encased in gauze — into easy-to-wear protective devices and ordered Chinese doctors, nurses and sanitary staff to use them. He also made sure that the masks were worn by patients and their immediate contacts, and he distributed some among the general public.
Wu’s Japanese and European colleagues on the ground were skeptical until the death of an eminent French doctor who wouldn’t cover up even while attending patients. Gauze masks were soon adopted, extensively. Some wearers would first stamp them with a seal from a temple — more than simply medical devices, the masks became talismans.
