Targeting Infectiologists in the US

Infectiologists are one of the highest-value and hardest physician audiences to reach online. There are only about 9,000 Infectiologists in the US, one of the scarcest and fastest-shrinking specialties, with many fellowship spots left unfilled each year, just as antimicrobial resistance, HIV, viral Hepatitis and emerging outbreaks keep demand climbing. Our HCP Targeting is audience-based, not Contextual, so we reach the Infectiologist as a clinician and as a person, wherever they browse: news, finance, technology, sport, travel, food, lifestyle and health content alike. That is broader reach across brand-safe, premium inventory, through Programmatic and Managed Campaigns, in the US.

HCP Targeting with USA Flag & Stethoscope

Our HCP Targeting (including this Infectiologist Targeting Segment) is available in the USA only, delivered with geo-targeting to the United States.

Need to reach HCP audiences based outside the US? It’s harder, but we’ve had success targeting them through Clinical Websites and Contextual Targeting.

The Infectiologist Audience

There are only about 9,000 Infectiologists in the US, one of the smallest and most stretched specialties in medicine, and many fellowship positions go unfilled every year. That scarcity is the point: Infectiologists are the experts other physicians and hospitals call when an infection is complex, resistant or life-threatening. They diagnose and manage HIV, viral Hepatitis, Tuberculosis, sepsis and bloodstream infections, hospital-acquired and drug-resistant infections, and infections in transplant and cancer patients, and they lead Antimicrobial Stewardship and vaccine strategy. They own long, high-value relationships with patients on lifelong therapy for HIV and Hepatitis, which makes them a high-value audience for Pharmaceutical, Diagnostics, Vaccine and Healthcare Technology brands. As antimicrobial resistance and emerging outbreaks keep rising against a shrinking workforce, Infectiologists sit at the center of a high-stakes and growing market, and are a high-value audience to reach at scale.

Why Advertise to Infectiologists

Infectiologists sit on top of one of the highest-value drug markets in medicine, built around lifelong and high-cost therapies. On the drug side they choose and manage Antiretrovirals for HIV and PrEP, Direct-Acting Antivirals for Hepatitis C, therapies for Hepatitis B, broad and last-line Antibiotics for resistant organisms, Antifungals and Antivirals, and Vaccines. On the diagnostics and technology side they drive demand for molecular and rapid Diagnostics, antimicrobial susceptibility testing, and the stewardship tools that guide how these drugs are used. Their influence reaches well beyond a single prescription. Infectiologists lead Antimicrobial Stewardship programs, sit on the committees that decide which antibiotics, antivirals and vaccines a hospital or plan will cover, and set the treatment pathways that Primary Care and other specialists follow for infections. Winning the Infectiologist shapes prescribing across the whole system.

Take an “Always On” Strategy for Targeting Infectiologists

Infectiologist TargetingInfectiologists are one of the smallest and busiest physician audiences in medicine: booked out for months, with new-patient waits that can stretch far longer, and full clinics managing complex chronic disease. You can rarely predict when one is online, whether it is between patients, after a full clinic day or on a weekend.

That is why we recommend an Always On strategy for an audience like this: run the campaign 24/7, 365 days a year so you reach Infectiologists whenever they surface, not just in a short burst. Continuous delivery builds reach and frequency over time, so you are already in front of them by the time your message matters most.

An Always On budget goes further with an Omnichannel approach. Rather than betting on one screen, you reach Infectiologists across the whole day: on their phone between patients, through a podcast in the car, on the office desktop between cases, and on Connected TV while they unwind at home. Same audience, more moments, more chances for your message to land.

Frequently Asked Questions (FAQs)

An Infectiologist is a physician who diagnoses and treats complex, severe and hard-to-manage infections. They complete Internal Medicine training plus an Infectious Disease fellowship, and they manage conditions like HIV, viral Hepatitis, Tuberculosis, sepsis, drug-resistant and hospital-acquired infections, and infections in immunocompromised patients. They also lead Antimicrobial Stewardship, travel medicine and vaccine strategy, and are the experts other doctors consult on difficult cases.

There are about 9,000 Infectiologists in the US, one of the smaller physician specialties, and the workforce is shrinking as many fellowship positions go unfilled each year. Demand keeps rising with antimicrobial resistance, HIV, viral Hepatitis and emerging outbreaks. That makes Infectiologists a scarce, high-value and hard-to-reach audience.

Infectiologists treat the full range of infections, especially the complex and serious ones. That includes HIV and AIDS, viral Hepatitis B and C, Tuberculosis, sepsis and bloodstream infections, endocarditis, bone and joint infections, drug-resistant and hospital-acquired infections, fungal infections, and infections in transplant and cancer patients. They also handle travel and tropical medicine, immunizations, and Antimicrobial Stewardship.

An Infectiologist is a physician who diagnoses and treats patients with infections. A Clinical Microbiologist is a laboratory expert who identifies the bacteria, viruses, fungi and parasites that cause disease and runs the tests that guide treatment. The two work closely together: the microbiology lab identifies the organism, and the Infectiologist uses that result to choose and manage the right therapy.
