Recently outpatient, unfortunately, there is a wonderful woman because of tattooing and then suffer from hepatitis C, in recent months, this has been my encounter 3 cases due to tattooing, eyebrow tattooing infected cases, are about 20 years old young people, it is clear that these cosmetic pathways to infection of the virus is not an accidental event. There is a study, the United States of America, New York University Lange Medical Center researchers in 2004 ~ 2006 years, three hospitals in New York outpatient clinics received nearly 2,000 people about tattoos and hepatitis C status of the investigation. The results found that 34 percent of people with hepatitis C had tattoos on their bodies, compared to a rate of only 12 percent of those who did not have hepatitis C. After taking into account the main risk factors for hepatitis C, the rate of tattooed people was four times higher among those with hepatitis C than among the general population. Dr. Fritz Francois, the leader of the new study, said that tattoos themselves may constitute a major risk factor for hepatitis C, and that the latency period for the risk may be as long as several years. Hepatitis C, or “hep C” as it is often called, is one of the more common forms of viral hepatitis, caused by infection with the hepatitis C (HCV) virus. Mainly through blood transfusion, blood products, hemodialysis, organ transplantation, and through the sterilization of syringes, infusion sets, medical equipment; vertical (intrauterine) transmission, mother-to-child transmission is also an important way of transmission of hepatitis C; it can also be transmitted through sexual contact, close contact with the family life, hepatitis C is characterized by a very high tendency to chronicity, cirrhosis, high incidence of hepatocellular carcinoma, is the main viral hepatitis in the West, China’s Hepatitis C is mostly spread due to occupational blood donation and blood transfusion in earlier years. Previously, rare routes of transmission included skin injuries, tattoos, and sharing razors and toothbrushes. However, it is these rare routes of transmission that have led to an increase in the incidence of hepatitis C in recent years: it has been reported that there has been a recent trend of an increase in the number of people suffering from “hepatitis C” in the coastal areas of China, Taiwan, Hong Kong, etc., and that those suffering from the disease are generally younger, and it is highly suspected that it is due to an increase in the number of teenagers who have piercings and tattoos. Hepatitis C and other kinds of viral hepatitis, its symptoms are hidden is its main feature, infected patients do not have any discomfort, a few patients will be found because of the physical examination of the liver function is mildly abnormal and consult a doctor, but the doctor must be given to the anti-HCV, HCV RNA these two tests in order to find out. It is recommended that all patients with tattoos, eyebrow tattoos, ear piercing, foot rubbing and other infectious pathways should have at least one of the above tests to exclude the possibility of hepatitis C infection.
