In this scenario, SIVcpz was transferred to humans as a result of chimps being killed and eaten, or their blood getting into cuts or wounds on people in the course of hunting. Apart from suggesting the current strains of HIV are likely to recombine in an unpredictable fashion – making the task of developing vaccines and treatments even more challenging than it already is – Cribb believes the findings have important implications for our understanding of retroviruses, the group of viruses to which SIV and HIV belong.

Hybrid Origin of SIV in Chimpanzees – Dimensions
As a result, it infects far fewer people, and is mainly found in a few countries in West Africa like Mali, Mauritania, Nigeria and Sierra Leone. News Video Monty the Python digests a whole wallaby. HIV may have originated as separate pathogens in monkeys Pic: But the origin of SIVcpz itself has been a mystery. It is far rarer, and less infectious than HIV Leave this field blank.

Byhalf of all infections in DR Congo were in locations outside of the Kinshasa area, reflecting the growing epidemic.
HIV is a type of lentivirus, which means it attacks the immune system. At first the disease was called all sorts of names relating to the word ‘gay’. When it transmutes into HIV, it becomes one of the worse killers of human beings and Asian monkeys. Ina few cases of rare diseases were being oribin among gay men in New York and California, such as Kaposi’s Sarcoma a rare cancer and a lung infection called PCP. The area around Kinshasa is full of transport links, such as roads, railways and rivers.
Latest In Depth Value of money is based on trust Bitcoin: The same area is known for having the most genetic diversity in HIV strains in the world, reflecting the number of different times SIV og passed to humans. Would you like to comment on this page?

The area also had a growing sex trade around the time that HIV began to spread. This explains why there is more than one strain of HIV American Museum of Natural History.
When to get tested? Xiv features web feed. You can find out more about the origins and history of HIV through our interactive timelinewhere you chimpanees read, watch, listen and explore key events from the history of the epidemic.
Global information and education on HIV and AIDS
The two different SIV strains then joined together to form a third virus SIVcpz that could be passed on to other chimps. You are here Home. Bailes and her team carried out extensive phylogenetic analyses comparing the structure of different strains of SIV to investigate the question.
The same scientists then conducted more research into how SIV could have developed in the chimps. The high population of migrants and sex trade might explain how HIV spread along these infrastructure routes. The AIDS-causing HIV virus is a hybrid of two monkey pathogens that swapped genes inside a chimpanzee, becoming the deadly global epidemic it is today, an international team of scientists report.
Hybrid origin of SIV in chimpanzees.
HIV first began to spread along the historic trade routes of the Congo basin in the s. Nevertheless, he agrees the new findings have important implications for public health.
This supports the hunter theory because every time SIV passed from a chimpanzee to a human, it would have developed in a slightly different way within the human body, and produced a slightly different strain. Julian Cribb, an Australian science writer and author of a book on the origin of AIDS, believes there is no evidence to support the idea that SIVcpz arose as a result of chimpanzees eating monkeys.
Use this form to email ‘HIV may be a hybrid mix of monkey viruses’ to someone you know: SIV is harmless in African monkeys. The most commonly accepted theory is that of the ‘hunter’. They concluded that the SIVcpz strain arose in chimpanzees through a series of transmission and recombination or genetic exchange events between SIVs in two species of monkeys: Please let us know any comments you have about the content on this page.
