If you want to know how one Covid-19 patient can set off a chain of infections, Delhi’s case No. 10 is a good example. The patient is a woman with a history of travel to Saudi Arabia. According to government data, five of Delhi’s 30 novel coronavirus cases so far, excluding her, are linked to her. This includes the Dilshad Garden resident’s two daughters, her brother, mother and a doctor who attended to her before she was taken to Guru Tegh Bahadur Hospital with high fever, cough and shortness of breath.
