Stats refreshed September 2026
A patient-friendly guide to infectious disease — what specialists do, the most common procedures (complex antibiotic management, hiv care and prep, travel medicine), and what to look for when choosing one.
Complex infections, travel medicine, and antimicrobial stewardship. Below: the procedures patients ask about most, the numbers that put the field in context, and the questions worth raising at a first consultation with a infectious disease specialist.
Top procedures & treatments
Complex antibiotic management
OPAT (outpatient parenteral antibiotic therapy) and stewardship.
HIV care and PrEP
Modern single-tablet regimens and long-acting injectables.
Travel medicine
Pre-travel vaccines, malaria prophylaxis, and post-travel illness.
Tuberculosis evaluation and treatment
Latent and active TB care.
Post-COVID and long-COVID care
Multidisciplinary management of post-acute sequelae.
By the numbers
Updated September 2026- Approximately 1.2 million people in the U.S. have HIV, while only 36% of those with a PrEP indication were prescribed the medication in recent years (CDC).
- Nearly 1 in 5 U.S. adults who previously had COVID-19 report experiencing symptoms of long COVID as of 2024-2025 (CDC/NCHS).
- Post-pandemic international travel surged 15% in 2024, driving record demand for pre-travel vaccinations and malaria prophylaxis (U.S. Travel Association/CDC).
- U.S. tuberculosis cases rose 16% in 2023, the highest level since 2013, necessitating increased active and latent TB screenings (CDC).
Trending this month: Patients are increasingly seeking long-COVID clinics and PrEP consultations as preventative health takes center stage. Complex antibiotic management remains a priority due to a 20% rise in multi-drug resistant infections nationwide (IDSA).
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.
