AIDS
December 4th, 2010
Hi folks! Hope you all doing well. at the moment I am going to give you some interesting information about the deadliest diseases in this world. Yes my dear readers today I am going to give you some useful and informative information about the AIDS. One of the deadliest diseases that made millions of people died for the last few decades is AIDS. Today I am going to give some information about the existence of AIDS in this world. The AIDS virus is estimated to have been among people from 100 years ago, aka a decade longer than the researchers expected. According to the latest study of genetic analysis, HIV has emerged between the years 1884 and 1924; with the closest estimate is the year 1908.
Previous estimates of HIV scientists began to emerge in 1930. But the new AIDS officially recognized in 1981 as the immune disease is loss of attention of health officials in the U.S. society.
This finding is not a monumental milestone, but it means the virus is already among us longer than we thought.
The researchers highlight that year was the emergence of HIV as the emergence of cities in Africa. They believe, contributed to regional development in the emergence and spread of HIV.
HIV is derived from a chimpanzee virus that moved to humans in Africa, especially when humans began to eat the great apes. Some people may be infected in this way, but many do not realize what happened.
As the city grows and more people live closer together and prostitution emerged, then the rapid spread of HIV began. “How to live in the city to make HIV spread faster because the virus is more easily move from one person to another,” said Worobey.
The findings were based on HIV samples taken from a woman in Kinshasa in 1960. This is the second sample is found before the year 1976, while the other samples obtained in 1959, also from Kinshasa.
Based on the fact that HIV mutates rapidly, then the two virus samples were compared. Genetic material difference counting backwards by considering how long they need time to grow into something different. Finally found when both are separated from a common ancestor.
In addition to using two samples from Kinshasa, the researchers also compared with 100 modern samples to create a viral family tree that was found early ancestors and appeared in 1884 until 1924.
Say the researchers, not surprising that the virus had been around a long time before finally recognized. The article caused the infection often takes several years to produce symptoms of illness. In addition, at the beginning of its appearance, it infects only a few people in Africa.
