Contagious disease refers to a communicable disease that can spread rapidly from person to person through direct contact (touching an infected person), indirect contact (touching a contaminated object), or droplet contact (inhaling droplets made when an infected person coughs, sneezes, or talks). HIV stands for human immunodeficiency virus. HIV attacks the body’s immune system, gradually destroying its ability to fight infections and certain cancers. If it is left untreated, HIV can develop into acquired immunodeficiency syndrome (AIDS). This is the most severe stage of HIV and is usually fatal. In the past, HIV infection was commonly considered a death sentence.
Today, AIDS is considered a chronic, life-threatening illness. AIDS symptoms include soaking night sweats, fever (for several weeks), persistent diarrhea, cough and shortness of breath, unexplained fatigue, blurred vision, white spots in the mouth, skin rashes and weight loss. It can be detected simply by a blood test. Unprotected sex with an infected partner is the most common route of infection for women.
Ways through which HIV can transmit:
HIV/AIDS can also be spread via blood. Some women become infected after sharing needles to inject drugs. A lack of knowledge about the virus and how it is spread is the main reason for the incredible spike of infections during the past three decades.
