HIV can lie latent in a person for years before it starts exhibiting symptoms.
A newly developed test can detect latent HIV in a body by specifically looking for a gene that is only expressed when HIV is present and replicating.
The test can also detect up to 70 times more HIV in a body than other tests (such as the current standard Q-VOA test).
HIV is the virus that causes AIDS, a disease which attacks the immune system itself instead of attacking an organ of the body. It appeared first in a 1959 death in the Congo and in a visiter to that country, Ardouin Antonio, who also died that year. But was only noticed by the general public when a man called Ken Horne died in 1980 of a disease (Kaposi’s syndrome) that was considered harmless. Read more about AIDS here.
