VATICAN CITY — Pope Francis, who began his fifth day in hospital on Tuesday for what doctors have described as a “complex” respiratory infection, will not take part in this weekend’s Holy Year events, the Vatican said on Tuesday. 

The 88-year-old pontiff has been suffering from a respiratory infection for more than a week and was admitted to Rome’s Gemelli hospital on Friday. 

A planned public papal audience set for Saturday had been canceled “due to the health condition of the Holy Father,” the Vatican said in a brief statement.  

A papal mass scheduled for Sunday will still take place, but will be led instead by a senior Vatican official, it added. 

The Vatican said on Monday that doctors had changed the pope’s drug therapy for the second time during his hospital stay to tackle a “complex clinical situation.” They described it as a “polymicrobial infection of the respiratory tract.” 

Doctors say polymicrobial diseases can be caused by a mix of viruses, bacteria and fungi. 

Francis, who has been pontiff since 2013, has had influenza and other health problems several times over the past two years. As a young adult he developed pleurisy and had part of one lung removed, and in recent times has been prone to lung infections.
