Worldwide, around 30 million people enter and leave prison each year. Of these people, around 4.5 million have hepatitis C, almost 1 million have HIV and 1.5 million have hepatitis B infections.
In many countries, prisons are underfunded and overcrowded, and injecting drug use is common. Those who enter prison uninfected are at risk of becoming infected, as few countries provide the range of prevention programs required to halt transmission inside.
Once detained, prisoners are often denied access to life-saving treatment for these infections.
