HIV/AIDs.
HIV is a virus most commonly caught by having unprotected sex or by sharing infected needles and other injecting equipment to inject drugs. (http://www.nhs.uk/conditions/hiv/pages/introduction.aspx)
Scientists believe HIV came from a particular kind of chimpanzee in Western Africa. Humans probably came in contact with HIV when they hunted and ate infected animals. Recent studies indicate that HIV may have jumped from monkeys to humans as far back as the late 1800s. (http://aids.gov/hiv-aids-basics/hiv-aids-101/what-is-hiv-aids/)
Symptoms: Most people who are infected with HIV experience a short, flu-like illness that occurs two to six weeks after infection. After this, HIV often causes no symptoms for several years.
It's estimated that up to 80% of people who are infected with HIV experience this illness.
The most common symptoms are fever, sore throat and body rash. Other symptoms can include tiredness, joint pain, muscle pain and swollen glands (nodes).
The symptoms, which can last up to four weeks, are a sign that your immune system is putting up a fight against the virus.

“HIV is an abbreviation for the human immunodeficiency virus which is the virus that causes AIDs. We know it is transmitted sexually, by exposure to blood and from mother to child. We also know that over time it weakens the body’s immune system, so that an infected individual becomes susceptible to a whole variety of serious infections and even some cancers. But that happens relatively very slowly, perhaps over 5, 10 or even more years.
The people most risk for HIV really depends on what part of the world you’re talking about. So in this country, in the UK, the most at risk is homosexual men, also recent immigrants from the sub-Saharan Africa and their sexual partners. There is also an epidemic associated with injection drug use and that’s been seen particularly in the southern parts of Europe”
