TOPSHOT - A man inhales vapours at a booth installed by Tanzanian herbalist Msafiri Mjema in Dar es Salaam, Tanzania, on May 22, 2020 as a preventive treatment against COVID-19 coronavirus. - People willing to undergo the treatment will pay 1000 Tanzanian shillings (about less than a half a US dollar) to enter the booth, and inhale vapours of water and salt, for 5 to 10 minutes. Steam inhalations are a popular traditional treatment for flu, high fever, and malaria. Tanzania's President John Magufuli said that one of his children had contracted COVID-19 coronavirus and had recovered thanks to steam inhalations using lemons and ginger. Tanzania is one of a few countries in Africa that have not taken extensive measures against the virus. (Photo by Ericky BONIPHACE / AFP)
