👉 Heptrevirinae is a group of viruses that are known for their ability to cause hepatitis, also known as liver disease. They belong to the family of retroviruses and are classified into two main groups based on their genetic structure: heparanases (Hepatitis E virus) and heparinase (hepatitis B virus). These viruses can infect both humans and animals, presenting symptoms such as abdominal pain, fever, jaundice, and liver failure.
