Does COVID-19 damage the liver?

Some patients hospitalized for COVID-19 have had increased levels of liver enzymes — such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Increased levels of liver enzymes can mean that a person’s liver is at least temporarily damaged. People with cirrhosis [liver scarring] may be at increased risk of COVID-19. Some studies have shown that people with pre-existing liver disease (chronic liver disease, cirrhosis, or related complications) who were diagnosed with COVID-19 are at higher risk of death than people without pre-existing liver disease.

How does COVID-19 mainly spread?
