Hepatitis C virus (HCV) causes both acute and chronic infection. Acute HCV infection is usually asymptomatic, and is only very rarely associated with life-threatening disease. The incubation period for hepatitis C is 2 weeks to 6 months. Following initial infection, approximately 80% of people do not exhibit any symptoms. Those who are acutely symptomatic may exhibit fever, fatigue, jaundice (yellowing of skin and the whites of the eyes). Causes Hepatitis C caused due to contact with contaminated blood or needles used to inject illegal drugs or draw tattoos. Sometimes you don't get any symptoms, or just mild ones. But in some cases hepatitis C leads to cirrhosis, a risky scarring of your liver.
HCV infection is diagnosed in 2 steps: Screening for anti-HCV antibodies with a serological test identifies people who have been infected with the virus. If the test is positive for anti-HCV antibodies, a nucleic acid test for HCV RNA is needed to confirm chronic HCV infection.Hepatitis C does not always require treatment as the immune response in some people will clear the infection, and some people with chronic infection do not develop liver damage. When treatment is necessary, the goal of hepatitis C treatment is cure.
Each of the hepatitis viruses causes similar liver damage. The inflammatory process is activated throughout the whole liver, and hepatocytes are destroyed by cytotoxic cytokines and natural killer cells, both parts of the inflammatory process. Cellular necrosis takes place. If inflammation affects the periportal areas, cholestasis, or the interruption of the flow of bile takes place.
statistics: Of the 41,026 individuals with a clinically reported HCV infection 12,384 (30%) were women. The majority (80%) were born in 1950 or later, with a high representation of people born in the 1950s (32%) and the 1960s (28%), and the median birth year was 1958 .The total number of people notified at age 20-24 was 375 in 1992, but has since then been about the same over the years (ranging from 188 to 294; mean 254 per year), but 20-24 was the most prevalent age at notification in 2006 as the number of notifications of older people had decreased. According to the reports, 91% of the HCV infected were native Swedes.
