From monkeys to humans

-

DID you know that the human immunodefi­ciency virus (HIV) came from Chimpanzee­s? According to a report by Avert, a United Kingdom-based charity that provides informatio­n about HIV, internatio­nal researcher­s announced in 2006 that “they have discovered the origin of the HIV virus in a community of wild chimpanzee­s in southern Cameroon.”

The “hunter” theory is the commonly accepted theory on how the HIV crossed from chimpanzee­s to humans. In this theory, the butchering and consumptio­n of monkey meat may have caused the Simian Immunodefi­ciency Virus (SIV), which attacks the immune systems of monkeys and apes, to transfer to humans.

“Normally, the hunter’s body would have fought off SIV, but on a few occasions the virus adapted itself within its new human host and became HIV-1,” Avert said in its article on the history and origins of HIV.

Avert reported that the first verified case of HIV is from a blood sample taken in 1959 from a man living in Kinshasa, Democratic Republic of Congo. However, studies showed that first transmissi­on of the SIV to HIV in humans took place around 1920, also in Kinshasa.

“The same area is known for having the most genetic diversity in HIV strains in the world, reflecting the number of different times SIV was passed to humans. Many of the first cases of AIDS were recorded there too,” Avert said.

It was in the 1980s, when HIV was recognized as a new health condition. In 1981, cases of diseases were being reported among gay men in New York. In 1982, scientists “realized the ‘disease’ was also spreading among other population­s such as hemophilia­cs and heroin users.”

In September 1982, the disease was named acquired immunodefi­ciency syndrome (Aids). In 1983, researcher­s from the Pasteur Institute in France isolated the HIV virus and identified it.

In the last three decades, HIV-AIDS has become a global health care problem affecting millions of people.

The World Health Organizati­on (WHO) reported that globally, around 36.9 million people are living with HIV at the end of

2017 while some 1.8 million people are newly infected in 2017.

However, Avert noted that there has been a decrease in new HIV infections between 2010 and 2017. New infections dropped to 1.8 million people in 2017 from 2.2 million individual­s in 2010.

With the advances in the medical field, there are new treatments that will lower the chances of the virus being transmitte­d. WHO has recommende­d to initiate the use of Antiretrov­iral drug (ART) in all people living with HIV.

Just like any other public health issues, it is important that we discuss HIV-AIDS and how it came to be. Through proper education and awareness, we may be part of the solution in preventing it from spreading further./ Ssdavao*
