New MSM Population Estimates Could Shift the Response to HIV Prevention: A How Do You AIDSVu Case Study

For many years, the HIV surveillance system has been “the conscience of the epidemic” and data on case counts and rates have been the most objective measures of our challenges and our successes in responding to the epidemic.

Our 30 second tutorial will teach you how to use the map.


Map Overview

Search for your location or use the mouse to click and drag the location you are viewing on the map, and the +/- buttons to zoom.



Each map has a legend that shows the map's color key and corresponding range.



Click City, County or State to view data at different levels of detail.


Data Set

Use the Prevalence Data toggle to see where people are living with HIV, and use the New Diagnoses Data toggle to see cases diagnosed in recent years. Prevalence data are a useful indicator of where the epidemic stands today, and where it has been in the past, while new diagnoses data indicate more recent trends and patterns.


Rate/Case Count

The map can be viewed by rates or by case counts. The rates show the number of cases per 100,000 people in the population to view the relative concentration of people in an area living with an HIV diagnosis. This differs from the number of cases, which is the actual number of people living with an HIV diagnosis. Additionally, the map view year can be selected from the dropdown list.


Demographic Filters

View the maps by race, age or sex by selecting here. If a filter is shaded, it is unavailable for the map view.


Transmission Categories

View prevalence data by transmission category, like male-to-male sexual contact, by choosing an option here.
