Stage 1-acute initial infection.
A quarter of people initial symptoms between two and five weeks after infection with HIV.
Stage 2 of asymptomatic HIV-infection.
Duringthe asymptomatic (without symptoms), which lasts on average 10 years or more, a person looks and feels completely healthy while the virus is actively reproducing in the body.
Human immunodeficiencyvirus is a lentivirus (which causes acquired immunodeficiency syndrome (AIDS).
It was discovered and regarded as the agent of the emerging AIDS epidemic by Luc Montagnier's team in France in 1983.The virion is spherical, provided with a casing and with a protein capsid. Its genome is a catenary Mono RNA strand to be copied to provisionally DNA and integrate Jan multiply the infected cellgenome.
The protein antigens of the outer envelope membrane proteins of infectable cells, especially lymphocytes.
The process of conversion of RNA to DNA is a major feature of retrovirus and is carriedout by reverse transcriptase enzymatic actions.
HIV has a diameter of approximately 100 nanometers.
H.I.V.
Human Immunodeficiency Virus
Stage 3-symptomatic HIV infection.
The beginning of thesymptomatic phase indicates that the immune system is weakening against the attack of HIV, making the body more susceptible to diseases that normally would control.
Stage 4-advanced symptoms: AIDS.As the immune system weakens below, developed symptoms of AIDS.
Ways of getting HIV or AIDS.1.
1.Through sex.
2. By blood transfusion from one person to another.
3. For syringes or used needles.4. In a pregnancy.
Forms of not getting HIV or AIDS.
