I have an exercise science test tomorrow, and am a bit confused about the differences between Hepatitis B, C, and HIV
Are all three primarily passed through contact with an infected person's blood? - or does one of them happen more often with semen, vaginal fluid etc.?
Can all three be contracted through sexual contact, semen, vaginal fluid etc?
HBV has flu like symptoms, and affects liver?
HCV also has flu like symptoms, and affects liver, but is much more serious?
HIV - like HCV it has no vaccine, and can kill you within around 2 years without medication?
