Italy's former prime minister Silvio Berlusconi, in hospital after testing positive for coronavirus, has the early stages of double pneumonia, national news agency ANSA reported on Friday.
Double, or bilateral, pneumonia affects both lungs and can make breathing difficult. The condition has been seen in many cases of patients hospitalised with COVID-19.
Berlusconi, 83, was taken to Milan's San Raffaele hospital on Thursday evening, two days after his Forza Italia party announced he had coronavirus.
