French President Emmanuel Macron is working in self-isolation from an official residence outside Paris after he tested positive for Covid-19 on Thursday in a result that caused alarm across Europe. "I am doing well. I have the same symptoms as yesterday: tiredness, headaches, a dry cough like hundreds of thousands of others of you," Macron said in a video message posted on his Twitter account that he appeared to have recorded himself with a phone.
