Tuberculosis evaluation and treatment
Latent and active TB care.
Post-COVID and long-COVID care
Multidisciplinary management of post-acute sequelae.
By the numbers
- ~1.2 million people live with HIV in the U.S.; modern therapy yields near-normal lifespan.
- Antimicrobial resistance contributes to 1+ million global deaths per year.
- PrEP reduces HIV acquisition risk by 99% when taken as prescribed.
How to choose the right specialist
Verify board certification, ask how many of your specific procedure the clinician performs each year, and review patient outcomes — not just star ratings. A infectious disease provider who clearly explains your options, the evidence, and the realistic recovery timeline is worth more than the most heavily advertised name.
