	Description:		The number of cases of Covid -19 infections in Brazil and deaths related to the pandemic may be much higher than official figures show. Testing of the living is not widespread and there are few resources for analysing the potential role of the virus as a cause of death. Virologist Fernando Spiliki gives us his bleak assessment. A remarkable study from South Africa shows just how easily the virus can spread around a hospital, with a single infected person infecting many. However the route of infection is not necessarily direct person to person transmission says investigator Richard Lessells from the University of KwaZulu Natal. And from London a study in a hospital with many Covid patients at the height of the pandemic supports the South African findings; Researchers found viral particles on surfaces and in the air says Professor Wendy Barclay from Imperial College. An early warning system for outbreaks of the virus or second waves may come from analysis of sewage, Jordan Peccia from Yale University analysed waste from his local sewage treatment works and found peaks in concentrations of the virus in the sludge occurred a few days before increases in hospital admissions.
