The infection worsened and developed into pneumonia in both lungs. He is currently experiencing an “initial, slight insufficiency” in his kidney function, according to the Vatican.

What is the current status of Pope Francis’s health? According to the Vatican, Pope Francis is in critical condition and he has been receiving treatment for the double pneumonia.

Pneumonia is an inflammation of the lungs, typically caused by a viral or bacterial infection. It occurs when the alveoli (small sacs in the lungs) become filled with pus and fluid, making breathing painful and limiting oxygen absorption.

Blood tests on Sunday also showed mild signs of kidney failure, but things are “currently under control”, the Vatican said, referring to the kidneys’ function of filtering waste products from the blood.

Francis also developed anaemia and, during blood transfusions on Saturday, received hematin, a treatment that can help increase haemoglobin levels, which in turn helps the blood carry more oxygen.
