When the HIV epidemic first appeared in the 1980s, there were few apparent benefits to being tested for this virus, as there were no effective treatments. Also, fear and ignorance about a person's HIV status sometimes led to discrimination.
Now, as we have entered the fourth decade of what has become the HIV pandemic, a range of effective and tolerable therapies is widely available, particularly for people who are initiating therapy. Researchers in high-income countries now predict that a young HIV-positive adult who begins therapy today and takes this therapy exactly as directed and who had no pre-existing health issues will likely live a near-normal lifespan. Such is the tremendous benefit of potent combination anti-HIV therapy (commonly called ART or HAART) in the present era.
After the introduction of ART, in the late 1990s researchers noticed that there was an increase in reports of high-risk sexual behaviour among men who have sex with men (MSM) -- unprotected anal sex. This has led to a resurgence of HIV infections in Canada, Australia, Western Europe and the United States. Not surprisingly, there has also been an increase in sexually transmitted infections (STIs) such as syphilis, gonorrhea and hepatitis C virus.
Through these efforts, public health officials hope to demystify HIV testing and help more people know their HIV status so they can receive care and treatment and take precautions to not pass on the infection. More widespread HIV testing should also incite awareness of the need to know one's HIV status and discussion of ways to reduce the risk of transmission.
However, breaking down perceived barriers to HIV testing will not be easy. Research in the European Union has found that barriers to HIV testing can be grouped into three main categories, as follows:
At the level of the person, key barriers to HIV testing can include the following:
Researchers in Scotland have been assessing changes in HIV testing behaviour among men who have sex with men over the past decade. In surveys of more than 1,600 men, a research team in Glasgow has found that what it calls a "partial normalization of HIV testing" seems to have occurred. The researchers also found that while some barriers to testing have been reduced, "other key barriers remain important." The barriers identified in the Scottish survey are somewhat unique to HIV disease and so are likely applicable to other regions in high-income countries and could inform programs that seek to encourage HIV testing that leads to care and treatment.
The research team surveyed men at "commercial gay venues" in Scotland at two points in time: in the years 2000 and 2010. Overall, 1,625 men were interviewed.
More men who completed the survey (14%) in 2010 reported having unprotected anal intercourse with two or more partners in the past year than in the 2000 survey (9%).
The researchers found that HIV testing behaviours changed as follows:
Proportion tested in the past 12 months
Proportion never tested for HIV
People surveyed in 2010 were significantly more likely to view HIV testing as beneficial and routine compared to a decade earlier.
However, the survey found that a) there were no significant differences in the fear of having an HIV-positive test result, and b) attitudes toward HIV-positive people had not changed.
