Introduction

Since it appeared in the early 1980s, the acquired immune deficiency syndrome (AIDS) and the human immunodeficiency virus (HIV) that causes it have wrought physical and social devastation around the world. in despite of many scientists researches, HIV/AIDS continues to be a major global public health issue.  AIDS remains unacceptable scourge that affects all especially countries and most deprived populations:37 million people live HIV/AIDS in the world and, in France, we still deplore about 6,000 new contaminations per year. AIDS, having claimed 36.3million (27.2-47.8) lives so far.

What is this progression today?

How the COVID-19pandemic has Impacted HIV/AIDS?

I-Brief History and origin of HIV/AIDS

AIDS was first described times in 1981.However, thanks to retrospectives studies on serums show that, a 1959 HIV virus could be identified. HIV infection in human came from a type of chimpanzee in central Africa. The chimpanzee version of the virus, (called simian immunodefiency virus, or SIV) was probably passed to humans when humans hunted these chimpanzees for meat and came in contact with their infected blood. Other studies have shown that HIV circulates in humans for longer than that. Since the end of the 19^th century probably HIV has an animal reservoir. At least forty species of monkeys Africans (including chimpanzees, gorillas, green monkeys, mangabeys, mandrills and cercocebes) are naturally infected with retroviruses similar to HIV. The infection does not cause AIDS in some of these species. Virus circulating among part of these species of nonhumans African primates have been transmitted to humans and have given rise to HIV type 1 and 2. At least 12human transmission events have occurred.it possible that HIV may have existed in an isolated population before spreading due to the increasing urbanization of world and the increase in flows of populations at beginning of the 20^th century.

II- HIV/AIDS, what is this?

HIV (human immunodeficiency virus) is a virus that attacks body’s immune system. If HIV is not treated, it can lead to AIDS (acquired immunodeficiency syndrome)

HIV infection affected the immune system, which is the body’s natural defenses against disease. yes, if left untreated, serious illnesses can occur. usually harmless infections, such as the flu or bronchitis can get worse, become very difficult to treat or even lead to death.

1-The causes of HIV/AIDS

HIV refers to the human immunodeficiency virus .it is transmitted sexually ,through blood ,and from mother to child .From mother to child may take place :either during the last trimester of pregnancy, by passing from HIV to through the placental barrier during blood exchange between the mother and the fetus ;either during childbirth, or….
