I am only talking about the US so I agree with you about the general population. However, the problem is serious relative to the size of one of the high risk groups that you mentioned since they account for roughly half of all the infections. Though that risk decreases through age 40 we are still talking about millions of people in either age group. As for MSMs, they do have a higher rate of incidence, especially when it comes to Syphilis and HIV, the 2 STDs with lowest overall infection numbers. Overall, MSM would be a subcategory within the larger age group. I would also like to know what the test rate is for the <25 group, but Im not sure the rate for the MSM group matters anymore than the white group or the obese group. I am also curious about the bisexual rate and their affect if any, being that they are the go between. My sample size was just over 30 people(laughable), most of which believed that no symptom meant no infection. It seems as though government and NGO's alike focus on awareness, of which testing happens to be a component. Not sure how successful they are. The other side is that even if testing is high, the process is tedious, which I can personally attest to. A person gets tested, then waits 3-5 business days to get their results. If positive, they then contact their partners. Assuming they still have their information, neither have blocked each other, and they make it over the hurdle that is stigma or shame. At which point their partner goes through the same process, and so on. All the while, all those who have yet to be notified are out in the world infecting others. The time it takes to test and treat someone is considerably slower than the time it takes to infect others. This is all conjecture, but the facts are limited and the stats we have are high. Due to the stigma associated with the topic its been tough getting people to talk so I honestly appreciate your response. After this I get the feeling that you'll be a critic of my idea, but hopefully a constructive one. My idea is to improve partner notification by taking a network approach which looks at partners to the 4th degree, and alerts those that may have been exposed. My hope is this will get more people tested. I understand the problems with my new partner receiving an alert that was set in motion by my ex, but if my new partner insists on condom use then we won't get alerts.
