CDC: New HIV Diagnoses for Black Americans Were Highest in Vulnerable Communities – Verywell Health
Key Takeaways
New CDC data shows that Black Americans are diagnosed with HIV at a rate that’s about four times higher than rates for all other racial groups combined.Some of the factors that drive higher rates of HIV transmission among Black Americans are lack of access to health care, discrimination, lack of awareness of HIV status, poverty, and stigma.The CDC in partnership with the federal government has launched an initiative to end the HIV epidemic in the next 10 years.
Despite progress made in curbing HIV (human immunodeficiency virus) nationwide, these improvements aren’t equal. A new Centers for Disease Control and Prevention (CDC) shows that disparities still persist among new HIV diagnoses, with Black Americans being diagnosed at a larger proportion than others.
The new data shows that Black Americans are diagnosed with HIV at a rate that’s about four times higher than rates for all other racial groups combined. Black adults accounted for 43% of the nation’s HIV diagnoses.
Additionally, the CDC found that rates of new HIV diagnoses among Black adults were higher in communities with the highest social vulnerability index (SVI). This index uses census data to determine the potential negative effects on the health of communities that are caused by external factors and stressors, such as natural or human-induced disasters and disease outbreaks.
What’s Driving Higher Rates?
Using data obtained from the National HIV Surveillance System (NHSS) and the 2018 CDC SVI, CDC researchers examined 13,807 diagnoses of HIV infection among Black adults in 2018 and the association between HIV infections and social vulnerability.
“The study found that 52% of Black adults diagnosed with HIV resided in areas in the country with higher social vulnerability index scores—often residentially segregated communities comprised predominately of Black people,” André Dailey, MSPH, CDC epidemiologist and lead study author, told Verywell.
Black adults in communities with high SVI were 1.5 times more likely to be diagnosed with HIV compared to those living in communities with lower SVI scores.
“Although social vulnerability does not explain all the disparity in HIV diagnosis, the study shows that Black adults in communities with high SVI scores might find it harder to obtain HIV prevention and care because of various factors,” Demetre Daskalakis, MD, MPH, director of the Division of HIV Prevention at the CDC, told Verywell via email.
These factors include:
RacismPovertyLack of access to health careLack of awareness of HIV statusStigma
A history of racial discrimination and residential segregation is correlated with factors associated with higher social vulnerability and higher rates of HIV diagnosis. Segregation limits Black people’s access to important resources and affects neighborhood quality.
Addressing High Rates of HIV Infection
Despite efforts to reduce transmission, HIV continues to disproportionately impact Black Americans and other vulnerable groups. Daskalakis said that the study underscores the continuing and urgent need to address the social determinants that contribute to disparities and deliver better HIV prevention and care to people who need it most.
This looks like addressing:
Unstable housingPovertyLimited access to health careSubstance use disorderTransportation to servicesHIV stigmaRacismDiscrimination
The Department of Health and Human Services announced the Ending the HIV Epidemic in the U.S. initiative in 2019, which aims to reduce new HIV infections in by 90% by 2030 by leveraging scientific data in HIV prevention, diagnosis, treatment, and outbreak response.
Through the initiative, the CDC and other government health agencies are partnering to allocate “resources to communities that could benefit from key, science-based HIV prevention strategies that are scaled up in innovative ways to reach populations equitably,” Daskalakis explained.
“The development and prioritization of interventions that address the conditions in which people are born, grow, live, work, and age, are critical to addressing those experiencing an increased risk of HIV infection among Black adults living in communities with higher SVI scores,” Daskalakis said.
And if implemented correctly, “these interventions might help prevent HIV transmission and reduce disparities among Black adults,” Daskalakis added.
What do these interventions look like? Some of it includes key prevention strategies like expanding access to pre-exposure prophylaxis (PrEP) in settings like STD clinics as well as syringe services programs.
