HIV can now come from animal to human493 views
Though the HIV wave carries on to terrorize health and well-being of a huge section of the world’s populace, but scientists have warned that latest types of the virus jumping from animals to humans cannot be ruled out.
HIV stands for human immunodeficiency virus. If left untreated, HIV can lead to the disease AIDS (acquired immunodeficiency syndrome). Unlike some other viruses, the human body can’t get rid of HIV completely. So once you have HIV, you have it for life. HIV attacks the body’s immune system, specifically the CD4 cells (T cells), which help the immune system fight off infections. If left untreated, HIV reduces the number of CD4 cells (T cells) in the body, making the person more likely to get infections or infection-related cancers. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. These opportunistic infections or cancers take advantage of a very weak immune system and signal that the person has AIDS, the last state of HIV infection.
The recommendation roots from a research study where the scientists exposed the initial in vivo proof that strains of chimpanzee-carried simian immunodeficiency virus (SIV) that virologists think the forerunner of HIV can infect human cells.
Qingsheng Li, who is the lead author of the study and Associate Professor at the University of Nebraska-Lincoln in the US, has stated that “The question was whether SIV strains that have not been found in humans have the potential to cause another HIV-like infection,”
Li further stated that “The answer is that, actually, they do. They get replicated at a very high level. It’s surprising,”
The investigators discovered that the SIV forerunner of HIV-1 M – the strain responsible for the global HIV pandemic – and an additional inherited strain of HIV discovered just amid locals of Cameroon can jump from animals to humans.
The investigators furthermore found that the SIV forerunners of two HIV strains not recognized in humans also held to attack human cells later than manifold contacts in the lab.
The results presented in the Journal of Virology.
Li further told that “The emergence and re-emergence of infectious diseases have become a constant threat to global health, social stability, safety and economic systems,”
Zhe Yuan, the lead author and doctoral student at the University of Nebraska-Lincoln, stated that the experimental approach used by the team could assist in evaluating the risk posed by supplementary SIVs and much further animal-carried viruses.
It could establish in particular vital provided the vibrant nature of HIV and other zoonotic diseases, he added, numerous of which are the reason for latest epidemics or even pandemics.
Yuan further added “I think this analysis of the disease is very important for public health,” Yuan, stated that the latest group of HIV strains was found in 2009.
