Understanding Hospital-Acquired Infections (HAIs)
Hospital-acquired infections, commonly known as nosocomial infections, are infections that patients contract during their stay in hospitals or other healthcare facilities. These infections are not present or incubating at the time of admission and typically manifest 48 hours or more after admission.
The most common types include:
- Surgical Site Infections (SSI)
- Catheter-Associated Urinary Tract Infections (CAUTI)
- Central Line-Associated Bloodstream Infections (CLABSI)
- Ventilator-Associated Pneumonia (VAP)
- Clostridium difficile Infections (CDI)
- Methicillin-Resistant Staphylococcus Aureus (MRSA) infections
According to the Centers for Disease Control and Prevention (CDC), about 1 in 31 hospitalized patients in the U.S. has at least one healthcare-associated infection on any given day. Early and precise diagnosis is essential to improve patient outcomes, reduce mortality rates, control outbreaks, and lower overall treatment costs.
Hospital Acquired Infections Diagnostics Market Size and Growth Forecast
The global Hospital Acquired Infections Diagnostics Market was valued at USD 4.2 billion in 2025 and is expected to grow steadily over the next decade. By 2035, the market is projected to reach USD 7.3 billion, reflecting a consistent CAGR of 7.1% from 2025 to 2035.
This growth is supported by increasing surgical volumes (over 310 million major surgeries performed annually worldwide), stricter infection control regulations, and technological innovations in diagnostic testing.
Key Drivers Fueling Market Growth
Several factors are propelling the expansion of the Hospital Acquired Infections Diagnostics Market:
- Rising Number of Surgical Procedures – Aging populations and the growing prevalence of chronic diseases are driving higher surgical volumes globally.
- Stringent Regulatory Requirements – Governments and healthcare bodies such as WHO, CDC, CMS, and NHS mandate HAI surveillance and reporting, encouraging adoption of advanced diagnostics.
- Growing Threat of Antimicrobial Resistance – The emergence of multidrug-resistant organisms (MDROs) like MRSA, VRE, and CRE demands faster and more accurate diagnostic tools.
- Technological Advancements – Innovations in molecular diagnostics, point-of-care testing, and automation are significantly improving detection speed and accuracy.
- Increased Healthcare Spending in Emerging Markets – Countries like India, China, Brazil, and Southeast Asia are rapidly expanding their healthcare infrastructure and diagnostic capabilities.
