What is HIV?
If left untreated, HIV can lead to AIDS (acquired immunodeficiency syndrome) disease. AIDS is the final stage of HIV infection which occurs when the body’s immune system is severely damaged because of the virus and unusual infection result. Untreated, HIV infection has a mortality of 90%.
How long does it take to notice signs of HIV?
- It may take a few weeks to several months for the virus to multiply, attack the immune system, and cause symptoms.
- Symptoms appear sooner in HIV-1 and progress faster than HIV-2.
How do you get HIV?
- Sexual intercourse (anal sex has a higher risk of transmission than vaginal sex)
- Sharing of infected needles (intravenous drug abuse) or razors
- Unsterilized tattoo needles
- Pregnancy and childbirth
- Exposure to infected blood (e.g., needle stick injuries)
- Contact between open skin wounds
HIV does not spread through:
What are the other signs and symptoms of HIV?
- Frequent infections.
- Poor wound healing.
- Increased susceptibility to serious infections such as pneumonia (infection of the lungs), meningitis (infection of the brain), tuberculosis, fungal infection.
- Symptoms of other disease would be more severe in HIV patients than normal patients because of the weakened immune system.
How is HIV diagnosed?
- History and physical examination by the physician
- Complete blood investigation, including specialized blood tests to detect the presence of the virus, immune status, and treatment progression.
- Specialized blood and radiological investigations to diagnose superadded infections.
How is HIV treated?
What is the HIV prognosis if not treated?
If untreated, HIV infection will progress to AIDS and the mortality rate is 90 percent. Though it cannot be cured, with appropriate treatment and precautions, patients can live up to a normal life expectancy (more than 70 years).
How can HIV be prevented?
- Practice safe sex by using the barrier method of contraception such as condoms.
- Avoid sharing needles and razors.
- Avoid touching spilled blood.
- Ensure tattoo parlors use sterile needles.
- Transmission from mother to baby can be prevented by starting antiviral therapy early during pregnancy.
- With needle stick injuries, immediately wash and disinfect the area and visit a doctor.
