Background: HIV-infected individuals with other STD have an increased risk of transmitting the virus to their sex partners. Therefore, starting STD prevention among HIV-infected people in a timely manner is one of key measures.
Objectives: to estimate the occurrence time of STD among HIV-infected people.
Methods:HIV-infected persons with new STD were identified from HIV/AIDS and STD surveillance registries among aged above 16 years residents at diagnoses of HIV and STD in Davidson County during 2005 to 2010. STD infection was defined as chlamydia, gonorrhea, primary/secondary or latent syphilis diagnosed at the same time or after HIV diagnosis. Duration from HIV to STD was derived from date of HIV diagnosis and date of lab result of STD reported.
Results: Of 154 identified persons, 30% were AIDS patients, and 70% had HIV-infection. Their average age was 30 years (IQR 24-37 years). Males were 88.3%. Non-Hispanic blacks were 55%, Non-Hispanic whites 31.8%, and Hispanics 8.4%. MSM only accounted for 68%. About 22% persons had more than one STD. After excluding reinfection, 183 STD infections were used in the analysis. The average duration from HIV to STD was 58 days. There were no statistical differences found for types of STD (P=0.38), race and ethnicity (P=0.95), risk factors of behavior (P=0.15), and gender (P=0.23). HIV-infected people had STD in significantly shorter time than AIDS patients (39 and 86 days, respectively), (P=0.046). There was no correlation between age at HIV/AIDS diagnosis and time of STD infection (P=0.35).
Conclusions:: the majority of HIV- infected persons had STD within 2 months of the diagnoses. HIV-infected people had STD in a much shorter time than AIDS patients.
Implications for Programs, Policy, and Research: Healthcare providers immediately provide STD screening and counseling to newly HIV- infected persons is a critical step to prevent STD within the identified population.
