The medical condition of Norway's King Harald has experienced a decline, according to a recent statement issued by the royal palace. The 89-year-old monarch continues to receive medical care at Oslo University Hospital, Rikshospitalet, where doctors are treating a bacterial infection in his bloodstream with antibiotics.

Palace officials noted that the king has shown a positive response to the antibiotic regimen despite the recent setback in his health. However, he will stay hospitalized and remain on an extended medical leave from his official duties until further notice.

King Harald has occupied the Norwegian throne since 1991 and was initially admitted to the hospital a week prior. During his absence, his son, 53-year-old Crown Prince Haakon, has stepped in to act as regent and manage official state responsibilities.

Medical challenges have increasingly impacted the sovereign in recent times. In the weeks leading up to his current hospitalization, he received cortisone treatments for haemolytic anaemia, an uncommon blood disorder that diminishes red blood cell counts and causes significant fatigue alongside shortness of breath.

Public appearances by the king have already been scaled back significantly due to his advanced age. Following a health scare while vacationing in Malaysia earlier in the year, during which he was fitted with a pacemaker, the royal household announced a permanent reduction in his schedule of public engagements.

The Norwegian monarchy has navigated a series of difficult circumstances over the course of the year. Crown Princess Mette-Marit underwent a lung transplant in June after managing a rare pulmonary fibrosis diagnosis for several years.

That medical procedure followed legal proceedings involving the crown princess's son, Marius Borg Høiby, who received a prison sentence after a criminal conviction. Furthermore, public scrutiny emerged earlier in the year regarding past associations between the crown princess and the late sex offender Jeffrey Epstein, prompting a public apology from Mette-Marit regarding her past judgment.
