AIDS is caused by the infection with the Human immunodeficiency virus(HIV). And it is a collection of symptoms known as Acquired Immuno Deficiency Syndrome. The destruction of the human immunity system by the virus leads to the opportunistic infection as well as an increased risk of autoimmune diseases and malignancy. The steps occurring in infection involve an interaction of HIV not only with the CD4 molecules on cells but also with other cellular receptors.
HIV/AIDS VIRUS & ITS SYMPTOMS
Diagnosis of HIV/AIDS
HIV is usually diagnosed by testing the blood and saliva for antibodies of HIV, which are usually found in the blood and saliva usually from 12 weeks. With technology advancements few tests have been introduced which can detect HIV antigen in the blood immediately after an infection. Few home kits are lately been approved by the FDA for the diagnosis of HIV by taking a swab of fluid from upper and lower gums.
Symptoms of HIV/AIDS
Immediately after exposure to HIV the affected individual may experience the following symptoms like nausea and vomiting, diarrhea, sore throat, aching of muscles, rashes, fever and fatigue. It is always not necessary that the person infected should always experience these symptoms as there are chances of aggravation of infection without any symptoms. Get the doctor’s opinion before undergoing any personal medications.
