Understanding Hospital-Acquired Infections (HAIs)

Hospital-acquired infections, also known as nosocomial infections, are contracted by patients during their stay in hospitals or other healthcare facilities. Common types include surgical site infections (SSI), bloodstream infections (BSI), urinary tract infections (UTI), ventilator-associated pneumonia (VAP), and Clostridioides difficile infections.

According to the U.S. Centers for Disease Control and Prevention (CDC), roughly 1 in 31 hospitalized patients has at least one HAI on any given day. These infections lead to longer hospital stays, higher treatment costs, and increased mortality risk. Early and accurate diagnosis remains the cornerstone of effective HAI management and prevention.

Hospital Acquired Infections Diagnostics Market Size & Growth Forecast

The hospital acquired infections diagnostics market was valued at USD 4.2 billion in 2025 and is expected to achieve a valuation of USD 7.3 billion by 2035, growing at a steady CAGR of 7.1% from 2025 to 2035.

This consistent growth reflects rising healthcare spending, technological advancements in diagnostic tools, and global initiatives aimed at reducing healthcare-associated infections.

Major Growth Drivers

  1. Surge in Surgical Procedures Worldwide More than 310 million major surgeries are performed globally each year, and the figure continues to climb due to aging populations and the increasing burden of chronic diseases.
  2. Rising Threat of Antimicrobial Resistance (AMR) Multidrug-resistant organisms such as MRSA, VRE, CRE, and carbapenem-resistant Enterobacteriaceae are making traditional diagnostics inadequate, accelerating demand for rapid molecular and genotypic testing solutions.
  3. Stringent Regulatory Frameworks Government programs like the U.S. Hospital-Acquired Condition Reduction Program and Europe’s infection control directives impose financial penalties on facilities with high HAI rates, pushing hospitals to invest in advanced diagnostics.
  4. Rapid Technological Advancements Innovations in polymerase chain reaction (PCR), next-generation sequencing (NGS), MALDI-TOF mass spectrometry, and point-of-care platforms are dramatically improving speed and accuracy.
  5. Increased Focus on Patient Safety Global campaigns by the World Health Organization (WHO) and national health authorities are raising awareness and enforcing stricter infection prevention protocols.
