🧵Please RT this #PublicHealth thread for internally displaced people & refugees in Sudan on how to disinfect drinking water.💦 You can kill pathogens in Sudanese surface water by boiling it for one minute.🔥 But another safe method uses the sun.☀️ #KeepEyesOnSudan #SudanUpdates
The @WHO recommends solar disinfection (SODIS) to disinfect drinking water when you cannot boil water. All you need is clear, plastic bottles, such as 1-liter or 2-liter bottles that previously held soda or juice. Place the bottles on a roof or in full sunlight for 6 hours.☀️ 
Six hours of exposure in full sunlight (or two days of exposure if the weather is cloudy) will pasteurize the water. The UV-A solar radiation combined with the heat from the sun for 6+ hours will destroy or deactivate most pathogens, making your water much safer to drink.
