CD4 and viral load test results, so estimates of percentages of persons retained in care are based on a limited number of states; 2) MMP data might include persons more likely to be retained in care or adhere to ART; and 3) the estimate assumed no viral suppression among persons not in care, although a small percentage of persons demonstrate viral suppression without taking ART.CDC's estimate that 28% of all HIV-infected persons are virally suppressed is higher than the 19% reported in a recent review (15). CDC used more recent data and different methods that did not depend on estimates of the proportion of persons in care who need ART. The previous estimate calculated that 80% of persons in care need ART, of whom 75% receive it (15).The 2010 National HIV/AIDS Strategy goals of reducing HIV incidence, increasing access to care and improving health outcomes for persons living with HIV, and reducing HIV-related disparities and health inequities are interdependent. Reducing national HIV incidence and improving individual health outcomes require increased access to care and elimination of disparities in the quality of care received. To meet these goals and break the cycle of HIV transmission in the United States, achieving high levels of engagement at every stage in the continuum of care is essential. Currently, a substantial proportion of HIV-infected persons have been tested and initially linked to care, and of those retained in care, 89% are prescribed ART, and 77% achieve viral suppression. However, only an estimated 28% of all HIV-infected persons in the United States are virally suppressed, largely because even among those with diagnosed infection, only 51% are receiving regular HIV care (8--11). Without substantial improvement in these percentages, 1.2 million new HIV infections would be expected to occur in the United States over the next 20 years (16). Based on estimated lifetime HIV treatment costs of $367,000 per person (2009 dollars) (17) caring for persons who become infected could cost as much as $450 billion in health-care expenditures (16).CDC supports state and local health department programs to expand and monitor HIV testing and linkage to medical care, especially in high prevalence areas. Because ensuring that persons with HIV infection receive continuous medical care is important, CDC is working with health departments throughout the nation to expand their efforts to collect laboratory reports on all CD4 and viral load test results for persons diagnosed with HIV. Local programs can use these data (in accordance with privacy and confidentiality policies, laws, and regulations) to identify persons not in care and to facilitate efforts to ensure they receive appropriate care. CDC will continue using MMP to monitor receipt of ART and prevention services among persons in care and identify opportunities for improvement. CDC will share this information with grantees, partners, health-care providers, and other federal agencies (e.g., the Health Resources and Services Administration) to improve the delivery of care, treatment, and prevention services for all persons with HIV infection.The results in this report indicate that progress has been made; however, continued and intensified efforts are needed. Only with success at each step
