Italy's mass testing programme to track cases of coronavirus is stretching the public health system to its limit. Poor organisation and widespread delays have left many people without tests, especially in poor neighbourhoods. Health authorities cannot cope with the long queues of people asking to get tested. But private tests cost €60 to €80 and many cannot afford that.

Two associations in Naples are offering COVID-19 tests to local residents at a controlled price of €18 or even for free. The free one is called a suspended swab test and takes its inspiration from a long-held tradition in Naples coffee shops.
