LONDON, July 25 (Thomson Reuters Foundation) — When Louis, a 29-year-old gay man, realised he had caught something “nasty”, the doctor initially thought it was herpes. His symptoms started with a rash, followed by a high temperature and blisters on his face. “I was warning any guys I’d had contact with, ‘Be careful — I’ve got something that’s weird’,” Louis, who asked not to use his real name to protect his identity, said by phone. “I called the doctor again and that time he said it was monkeypox.” Louis, who is French and lives in Berlin, is one of more than 10,000 people across Europe who have been infected in the first monkeypox outbreak in multiple countries outside of areas of West and Central Africa where it is endemic.
