The HIV virus is very difficult to diagnose from symptoms alone, and it is estimated that 1 in 3 people who have the infection in the UK remain undiagnosed. There are a number of high-risk groups that could potentially catch the infection and these include:
It is of the utmost importance that you have a HIV test if you are in one of these high-risk groups. The HIV test is done by taking blood and testing it for the presence of the HIV virus, but the test will only detect the presence of the virus after three months of the initial infection. It is advised that a second test be taken three months after the first one.
