HIV is a virus that is spread through unprotected sex (oral, vaginal, or anal). If only one of the partners has the virus, it can be spread to the other.
Symptoms- pain in abdomen, pain while swallowing, cough, fatigue, fever, loss of appetite, sweating, vomiting, diarrhea, nausea, ulcers or white tongue in mouth, sores or swelling in the groin. HIV is also chronic, as it stays with the host for life.
HIV can also be a lethal disease in some cases. It attacks the immune system by destroying cells that attack it so there is no way to stop it on your own.
Treatment- to treat HIV, you can only suppress the symptoms and seek a doctor immediately if you think you have it. You should also tell your sexual partner that they have HIV.
HIV killed nearly 2.5 million people in the US last year and is most common in Africa. More than 95% of HIV infections are in developing countries.
