What are the dangers of hepatitis C? There is a general lack of attention to hepatitis C and a very low rate of knowledge about the disease, and even widespread misconceptions. The results of the Hepatitis C Awareness Survey published by the China Hepatitis Prevention and Control Foundation show that 76% of respondents did not know that hepatitis C is curable, and 80% of respondents even incorrectly believed that “vaccination can prevent hepatitis C”. Because of this, many hepatitis C patients are missing out on the best time to get treatment. There is no vaccine available for hepatitis C worldwide. The results of a survey on the prevalence of hepatitis C in China show that the number of reported cases of hepatitis C in 2008 was about 120,000, six times higher than in 2003. Hepatitis C has also been underappreciated by the public and is the statutory infectious disease with the highest clinical underreporting rate. Hepatitis C is a major cause of cirrhosis and liver cancer, resulting in approximately 300,000 deaths each year in China. The main danger of hepatitis C is that it leads to cirrhosis and liver cancer. Hepatitis C has no abnormal reaction during the incubation period, making it impossible to detect it at once. The incidence of hepatitis C in China is also quite high, with about 50% of hepatitis C patients turning into cirrhosis, and nearly 50% of these cirrhotic patients developing liver cancer. This shows that considerable attention should be paid to hepatitis C. The transmission of hepatitis C, the pathway are: 1, blood transmission, mainly: (1) by blood transfusion and blood products transmission. Since 1993, when blood donors were screened for anti-HCV, this route has been effectively controlled. However, due to the existence of window period of anti-HCV, the unstable quality of anti-HCV testing reagents and the fact that a few infected people do not produce anti-HCV, it is impossible to completely screen out HCV-positive people, and a large number of blood transfusions and hemodialysis may still be infected with HCV. (2) Transmission via broken skin and mucous membranes. This is by far the predominant mode of transmission, and in some areas, HCV transmission due to intravenous drug use accounts for 60% to 90%. The use of non-disposable syringes and needles, dental instruments without strict sterilization, endoscopy, invasive operations and needle sticks are also important ways of transdermal transmission. 2.Sexual transmission: The risk of HCV infection is higher for those who have sexual intercourse with HCV infected persons and those who have sexual promiscuity. 3.Mother-to-child transmission: The risk of HCV transmission from an anti-HCV-positive mother to her newborn is 2%, but if the mother is positive for HCV RNA at the time of delivery, the risk of transmission can be as high as 4% to 7%. high HCV viral load may increase the risk of transmission. 4, other: tattoo, tattoo eyebrows, ear piercing and other cosmetic, manicure, pedicure and other invasive operations hidden infection crisis. 5.The transmission route of some HCV infected people is unknown. Kissing, hugging, sneezing, coughing, food, drinking, sharing utensils and water glasses, no skin breaks and other contacts without blood exposure generally do not transmit HCV. Treatment of hepatitis C The chronicity rate of hepatitis C is too high and the treatment is mainly antiviral therapy with interferon combined with ribavirin, long-acting interferon is played once a week and ordinary interferon is played every other day, the chances of sustained response to long-acting interferon is 10% higher than The chance of sustained response with long-acting interferon is 10% higher than with regular interferon. Interferon alone is not good, but should be added to ribavirin. There is a standardized treatment regimen, but on top of the standard, there is an individualized regimen for appropriate adjustments. Chronic hepatitis C treatment should be individualized based on viral genotyping and patient response. Interferon has many side effects and ribavirin also has adverse effects, so treatment regimens need to be properly guided by a specialist physician at a specialized hospital. With the clinical application of interferon combined with ribavirin, the gold standard of hepatitis C treatment, the cure rate of hepatitis C has reached about 70%.
