COVID-19 is primarily transmitted person to person via respiratory droplets. A few studies have isolated viral RNA in both stool and urine of a small number of severely ill patients with COVID-19. It is less clear whether this represents viral shedding or infectious virus in these samples. Proper hand hygiene should be used at all times when changing diapers or any other time that you may come in contact with stool or urine.
