🧵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.
Boiled water or pasteurized water may taste flat. To make it taste better, pour the water back and forth from one clean container to another to reoxygenate it (to add more oxygen to the water, which improves the flavor).🍶🍶
This safe and effective method of solar water disinfection (SODIS) is used by more than 2 million people in 28 countries to disinfect their daily drinking water, according to the Centers for Disease Control (@CDCGlobal). ☀️💦🍶
