MEXICO CITY (Reuters) - Dozens of people waited in their cars and on the sidewalk at a laboratory in an upscale Mexico City neighbourhood on Wednesday to be tested for coronavirus, eager for diagnoses despite the government's insistence that not everyone needs to be tested.

Mexico has reported 475 cases of coronavirus since detecting the first infection in late February, although some experts say the government's limited testing means the true number could be higher. Six people with the virus have died.
