HBV stands for Hepatitis B virus, a serious and potentially life-threatening infection that affects the liver. There are a number of synonyms for HBV, including viral hepatitis B, serum hepatitis, and B-type hepatitis. Hepatitis B is a highly contagious viral infection that is transmitted through contact with infected blood or bodily fluids. Symptoms of HBV include fatigue, fever, loss of appetite, nausea, vomiting, abdominal pain, and yellowing of the skin and eyes. There is currently no cure for HBV, but there are treatments available that can help manage the symptoms and slow down the progression of the disease. It is important to get vaccinated against HBV and to practice safe sex and drug use to prevent the spread of infection.
