People with risky behaviors should be tested regularly. Over decades, the virus slowly spread across Africa and later into other parts of the world. The area also had a growing sex trade around the time that HIV began to spread. Others remain completely healthy after 10 or even 20 years. Many of the first cases of AIDS were recorded there too.
Taking antiretroviral therapy regularly helps many people slow the progression of HIV and reach viral suppression. The lack of transport routes into the North and East of the country accounts for the significantly fewer reports of infections there at the time.
Age when symptoms start. How did HIV spread from Kinshasa?
Learn more about HIV and life expectancy. The area also had a growing sex trade around the time that HIV began to spread. The two different SIV strains then joined together to form a third virus SIVcpz that could be passed on to other chimps.

HIV stands for human immunodeficiency virus. Some molecular dating studies suggest that HIV-1 group M had its most recent common ancestor MRCA that is, started to spread in the human population in the early 20th century, probably between and During this time, the amount of CD4 cells starts to fall very quickly.
This stage can last 10 years or longer. The chronic HIV stage is known as the latent or asymptomatic stage. Some people seem to progress more quickly through their disease given their genetic makeup.
Treatments for HIV typically involve antiretroviral therapy.
People with weakened immune systems are also more susceptible to certain types of cancersuch as lymphoma and cervical cancer. It is far rarer, and less infectious than HIV The first verified case of HIV is from a blood sample taken in from a man living in what is now Kinshasa in the Democratic Republic of Congo.

Following the failure of his immune system, he succumbed to pneumonia. Doctors, baffled by what he had died from, preserved 50 of his tissue samples for inspection.
Immune cells can only look for viruses that resemble the previous generation of HIV, so the virus constantly ‘escapes’ the immune system. CD4 T-cells gradually decline in number.
This is because they are killed by HIV and also because they are over-activated and this leads to increased T-cell death. Diseases of immune origin. The immune system protects against infectious disease, Acquired immune deficiency syndrome is caused by infection with the human immunodeficiency virus (HIV), which destroys a certain type of T lymphocyte, the helper T cell.
AIDS, byname of acquired immunodeficiency syndrome, transmissible disease of the immune system caused by the human immunodeficiency virus ().HIV is a lentivirus (literally meaning “slow virus”; a member of the retrovirus family) that slowly attacks and destroys the immune system, the body’s defense against infection, leaving an individual vulnerable to a variety of other infections and.
Human immunodeficiency virus (HIV) is the virus that causes AIDS. When a person becomes infected with HIV, the virus attacks and weakens the immune system. As the immune system weakens, the person is at risk of getting life-threatening infections and cancers.
AIDS, HIV and The Immune System.
the result of which is loss of the ability of the body to fight infection and the subsequent acquisition of diseases such as pneumonia. We will examine the virus itself, the immune system, the specific effect(s) of HIV on the immune system, the research efforts presently being made to investigate this.Download
