HIV is a viral infection caused by the human immunodeficiency virus or HIV. It causes severe damage to the body's immunity. Due to HIV/AIDS, a person's ability to fight infection is reduced and this problem increases over time, due to which the person's chances of getting infections and diseases increase.
If nothing is done for HIV, then it can cause AIDS. AIDS is the last stage of HIV infection in which a person starts getting many deadly infections and cancer.
The initial symptoms of HIV are like flu which get cured on their own in some time and that is why most people do not know that they are infected with HIV and this virus keeps growing in their body. In the last stage, it causes blurred vision, dry cough, weight loss and shortness of breath.
It is believed that HIV infection spreads easily, but this is not true. This infection spreads by coming in contact with the body fluids of an infected person, such as blood, semen, breast milk or other genital secretions. The most common way of spreading it is by having sex without a condom. HIV infection does not spread through normal activities like shaking hands, hugging, kissing, sharing things or mouth-to-mouth.
Your HIV test is done to detect HIV infection and you are given proper treatment according to the stage. Although there is no cure available for HIV infection yet, some treatments can stop the growth of the virus, so that the person does not get AIDS and can live a healthy life.
