Abstract
Using photo-epidemiology, we found extreme variation in COVID-19-related face covering use in Phnom Penh, Cambodia (97%); Lima, Peru (86%); Kerala, India (41%); Cuernavaca, Mexico (25%); Atlanta, USA (21%) and Kinshasa, DRC (4%) probably attributable to differences in population experience with face coverings and variations in timing and implementation of relevant advisories.
