WebMD (https://www.webmd.com/hepatitis/digestive-diseases-hepatitis-c https://www.webmd.com/hepatitis/digestive-diseases-hepatitis...) says that 3.9 million people in the US have this disease, more than 1 in 100 of the population. And https://hepatitisc.net/what-is/statistics/ https://hepatitisc.net/what-is/statistics/ says that worldwide abou 70 million, again roughly 1 per 100. This seems rather a lot. What is missing from the statistics I have been able to find is any breakdown by location, lifestyle, diet, etc. The only hint is that the majority of injection-drug users are infected and that poor blood screening in the past has contributed. If this disease is so widespread it seems to me that public health measures that prevent or reduce the risk of infection must, in the long run at least, be necessary. What measures might they be and is there anything that an individual can do to reduce their risk?
