Hepatitis Giant Microbe

• HAV is spread primarily by unsanitary food and water
• HBV is transmitted in bodily fluids and can cause chronic liver disease
• HCV is perhaps the most dangerous: no vaccine is available
• HDV occurs only in the presence of HBV
• HEV is relatively mild and non-chronic
• HFV and HGV are newly identified; their connection with liver disease is debated
