New figures show that Brazil now has the fourth largest outbreak of the coronavirus in the world. Nearly 240,000 people are infected and more than 15,000 have died of COVID-19. Health experts say a lack of testing means the real figures could be much higher, and warn the worst is yet to come. And researchers are testing whether specially-trained dogs can sniff out the Coronavirus in humans -- even before symptoms are evident. Teams in the UK and the US have begun trials to find out whether canines can detect unusual scents coming from people infected with COVID-19. Success could transform the global response to the global coronavirus pandemic. In other news:
