Experts from King’s College London compiled the report earlier in the year titled “Mapping Maximum Biological Containment Labs Globally” in an effort to highlight the “significant risks” posed by the labs amid the pandemic.

The paper – and accompanying interactive map – shows the 59 biosecurity level four (BSL-4) locations, both in operation or planned, which deal with some of the most deadly pathogens.
It highlights 18 in Europe, 14 in North America, 13 in Asia, seven in Britain, four in Australia and three in Africa.
More than three quarters of the world’s BSL4 labs – some 46 – are also located in urban areas, meaning impacts of any leak could have devastating consequences.
