Approximately 50 000 new human immunodeficiency virus (HIV) infections develop in the United States each year.1 How many of these people know of their HIV infection? How many are engaged in HIV care? How many are successfully treated with antiretroviral therapy (ART)? Surprisingly, until very recently, the answers to these simple questions regarding HIV care were unknown.
