Human immunodeficiency virus (HIV) is a retrovirus that can lead to acquired immunodeficiency syndrome (AIDS), a condition in humans in which the immune system begins to fail, leading to life-threatening opportunistic infections.
What are the early symptoms of HIV infection?
Many people do not develop any symptoms when they first become infected with HIV. Some people, however, get a flu-like illness within three to six weeks after exposure to the virus. This illness, called Acute HIV Syndrome, may include fever, headache, tiredness, nausea, diarrhoea and enlarged lymph nodes (organs of the immune system that can be felt in the neck, armpits and groin). These symptoms usually disappear within a week to a month and are often mistaken for another viral infection.
During this period, the quantity of the virus in the body will be high and it spreads to different parts, particularly the lymphoid tissue. At this stage, the infected person is more likely to pass on the infection to others.
More persistent or severe symptoms may not surface for several years, even a decade or more, after HIV first enters the body in adults, or within two years in children born with the virus. This period of "asymptomatic" infection varies from individual to individual. Some people may begin to have symptoms as soon as a few months, while others may be symptom-free for more than 10 years. However, during the "asymptomatic" period, the virus will be actively multiplying, infecting, and killing cells of the immune system.
What are the later symptoms of HIV/AIDS?
Lack of energy
Weight loss
Frequent fevers and sweats
A thick, whitish coating of the tongue or mouth (thrush) that is caused by a yeast infection and sometimes accompanied by a sore throat
Severe or recurring vaginal yeast infections
Chronic pelvic inflammatory disease or severe and frequent infections like herpes zoster
Periods of extreme and unexplained fatigue that may be combined with headaches, lightheadedness, and/or dizziness
Rapid loss of more than 10 pounds of weight that is not due to increased physical exercise or dieting
Bruising more easily than normal
Long-lasting bouts of diarrhoea
Swelling or hardening of glands located in the throat, armpit, or groin
Periods of continued, deep, dry coughing
Increasing shortness of breath
The appearance of discoloured or purplish growths on the skin or inside the mouth
Unexplained bleeding from growths on the skin, from mucous membranes, or from any opening in the body
Recurring or unusual skin rashes
Severe numbness or pain in the hands or feet, the loss of muscle control and reflex, paralysis or loss of muscular strength
An altered state of consciousness, personality change, or mental deterioration
Children may grow slowly or fall sick frequently. HIV positive persons are also found to be more vulnerable to some cancers.
What Happens Inside the Body?
Once HIV enters the human body, it attaches itself to a White Blood Cell (WBC) called CD4. Also, called T4 cells, they are the main disease fighters of the body. Whenever there is an infection, CD4 cells lead the infection-fighting army of the body to protect it from falling sick. Damage of these cells, hence can affect a person's disease-fighting capability and general health.
Causes Of AIDS & HIV :
Infection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate, or breast milk. Within these bodily fluids, HIV is present as both free virus particles and virus within infected immune cells. The four major routes of transmission are unprotected sexual intercourse, contaminated needles, breast milk, and transmission from an infected mother to her baby at birth. Screening of blood products for HIV has largely eliminated transmission through blood transfusions or infected blood products in the developed world.
You can't get it from mosquito bites, coughing or sneezing, sharing household items, or swimming in the same pool as someone with HIV.
