HIV is a deadly disease caused by the Human Immunodeficiency Virus. It has affected millions of persons worldwide and has no cure discovered until today. Many awareness measures have been undertaken to educate people about this HIV AIDS disease. A HIV test can help know whether you are infected or not.
Transmission from primates
HIV test has proved transmission of pathogens from the apes to the humans. The human population of Africa was living near the population of the host animals. The infectious pathogen of the monkeys and apes had the capability to attack and invade humans too. The SIV virus, the infectious pathogen, was found in abundance in Africa. The human population must have encountered thousands of direct exposure to the virus, through which the virus gained a successful foothold on the human population. The HIV test also shows the mutative history of the virus. The virus has undergone several mutations to boost its ability of invading humans to humans. Thus, HIV started spreading to the human population in the late 19th century.
Diminished male population
The Africa of that time was abundant with infected animals. Africa came under the colonial rule and was subjected to a lot of new changes. Major numbers of the male population were shipped to the ports and other countries for work. This disturbed the female and male ratio, promoting sexual promiscuity. This condition promoted intercourse with different and multiple partners, promoting the spreading of HIV. HIV testing was not known at that time.
The colonial forces that settled in Africa shipped many of its population to many countries worldwide for working as slaves in their plantations. Many of the human populations of Africa were infected; and this increased movement of people promoted the spreading of HIV. The HIV test has been found positive in many individuals of Africa.
The harsh and new working conditions lead to many epidemics among the Africans. They were vaccinated for these epidemics by their colonial masters. But these vaccinations were very unhygienic and unsafe. They were not administered properly. Vaccinations against small pox, trypanosomiasis, leprosy, yaws, sleeping sickness, Schistosomiasis, tuberculosis and syphilis were very commonly administered to all, but the injections and equipments were not sterilized before and after use. These unsafe and unsterile vaccinations led to the spreading of the HIV virus. Today, HIV test is done during organ transplants and blood donations to screen for the presence of HIV virus.
The immune of the workers were suppressed due to the extreme stress of forced labor and harsh conditions. This depressed immune system would have easily given a lot of chances for the SIV virus to infect and mutate in their body. The weak immune system could not fight against these viruses effectively.
Bush meat was served to all laborers in those days. Many primates were killed for meat, out of which many have become endangered and extinct now. Great apes, monkeys and lemurs were killed for meat. If a person with an open wound in his hand butchered the meat, or hunted the animal and brought it back, the infected blood of the animal can come in direct contact with the blood of the person. Thus HIV was transferred.
