2. Hepatitis B
Hepatitis B is a viral infection which can be life threatening in certain cases. Sufferers are thus at a high risk of cirrhosis and cancer of the liver. It spreads through various means and can even survive outside of the body for seven days. Exposure is most often caused by coming into contact with the blood or body fluids of a sufferer. Sexual intercourse also spreads this viral infection. The risk is highest in men who have sex with men, as well as sex workers and those employing their services. Drug users who inject their substances are also at risk, due to the unknown purity of the drugs. The reuse of others’ needles is also a huge risk factor. Many oral retro viral drugs are effective in treating this condition, but no single cure exists.
