Augustin Yenga Bosongo, 73, a nurse, gives medicines to Otikala Itawelo, 10, to calm his fever at the Yalanga health centre, in Yakusu, Tshopo, Democratic Republic of Congo, October 2, 2022. The village of Yalanga is a day's journey from Yalolia by land and boat. Surrounded by jungle, it has no phone network or electricity. When the light fades, patients at the health centre lie in the dark on beds of hard bamboo. The clinic, a small building with a tin roof and five rooms, has had three monkeypox cases in the recent months. To notify the authorities of a new case, nurses must travel half a day to get phone reception. When they are busy, getting away is impossible. The recent cases were recorded weeks late, said nurse Alingo Likaka Manasse. REUTERS/Arlette Bashizi SEARCH "BASHIZI MONKEYPOX" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES.
