From Jan Kulveit: A very inexpensive and effective mitigation measure is the compulsory wearing of masks. This has been implemented in several Asian countries. Masks do not protect the wearer – but they protect from infection by pre-symptomatic and asymoptomatic individuals. They also remind everyone of the need for distancing and lack of a mask is a signal of someone not taking the situation seriously and so should be avoided. Additional policy recommendations from his group here.
