Some patients experience early symptoms of hepatitis C genotype 1a that include fatigue, fever, muscle aches and loss of appetite, according to MedicineNet. Approximately 75 percent of patients have no early symptoms. As the disease progresses, yellowing of the skin or eyes sometimes occurs.
Genotype 1 is the most common form of hepatitis in the United States, according to MedicineNet, and the genotype is divided into types 1a and 1b. As of March 2015, hepatitis causes 8,000 to 10,000 deaths in the U.S. each year. Prompt treatment is vital to limit the damage done by the disease and reduce the risk of liver failure.
