the virus of aids affects the growth of?
cd4 t cells
bullet::::- hiv (human immunodeficiency virus) damages the body's immune system, which interferes with its ability to fight off disease-causing agents. the virus kills cd4 cells, which are white blood cells that help fight off various infections. hiv is carried in body fluids, and is spread by sexual activity. it can also be spread by contact with infected blood, breast feeding, childbirth, and from mother to child during pregnancy. when hiv is at its most advanced stage, an individual is said to have aids (acquired immunodeficiency syndrome). there are different stages of the progression of and hiv infection. the stages include primary infection, asymptomatic infection, symptomatic infection, and aids. in the primary infection stage, an individual will have flu like symptoms (headache, fatigue, fever, muscle aches) for about 2 weeks. in the asymptomatic stage, symptoms usually disappear, and the patient can remain asymptomatic for years. when hiv progresses to the symptomatic stage, the immune system is weakened, and has a low cell count of cd4+ t cells. when the hiv infection becomes life-threatening, it is called aids. people with aids fall prey to opportunistic infections and die as a result. when the disease was first discovered in the 1980s, those who had aids were not likely to live longer than a few years. there are now antiretroviral drugs (arvs) available to treat hiv infections. there is no known cure for hiv or aids but the drugs help suppress the virus. by suppressing the amount of virus in the body, people can lead longer and healthier lives. even though their virus levels may be low they can still spread the virus to others.

economic impact of hiv/aids





















































hiv and aids affects economic growth by reducing the availability of human capital. without proper prevention, nutrition, health care and medicine that is available in developing countries, large numbers of people are falling victim to aids.





















































people living with hiv/aids will not only be unable to work, but will also require significant medical care. the forecast is that this will probably cause a collapse of babies and societies in countries with a significant aids population. in some heavily infected areas, the epidemic has left behind many orphans cared for by elderly grandparents.
