Milan the northern region of Lombardy which has borne the brunt of Italy's coronavirus outbreak has no case. Alberto further told RAI television that "The swabs that were performed over the last 10 days showed a viral load in quantitative terms that was absolutely infinitesimal compared to the ones carried out a month or two months ago.

A clinical trial of hydroxychloroquine as a means of treatment for COVID-19 has been temporarily suspended by the World Health Organization, WHO. The move by WHO followed new data suggesting that the drugs increase mortality among patients.

Phase1 human trial of a COVID-19 vaccine called the Ad5-nCoV shows that it is safe, well-tolerated and able to generate an immune response against the SARS-CoV-2 in participants. The trial demonstrates that a single dose of the new vaccine produces virus-specific antibodies and T cells in 14 days, making it a potential candidate for further investigation.
