Hospital-Acquired and Ventilator-Associated Bacterial Pneumonia (HABP/VABP) Market is projected to reach USD 5.9 billion by 2034

Hospital-Acquired and Ventilator-Associated Bacterial Pneumonia (HABP/VABP) Market Outlook 2024-2034: Rising Antimicrobial Resistance Spurs Innovation in Antibiotics and Diagnostics
Introduction
Hospital-acquired bacterial pneumonia (HABP) and ventilator-associated bacterial pneumonia (VABP) are among the most severe healthcare-associated infections (HAIs), typically occurring in critically ill patients or those requiring prolonged mechanical ventilation. These infections are associated with high morbidity, mortality, and healthcare costs, making them a central focus for antimicrobial stewardship and drug development.
HABP and VABP are commonly caused by multi-drug resistant (MDR) pathogens, including Pseudomonas aeruginosa, Klebsiella pneumoniae, Acinetobacter baumannii, and methicillin-resistant Staphylococcus aureus (MRSA). With limited effective therapies and rising antimicrobial resistance (AMR), the demand for novel antibiotics, rapid diagnostics, and combination regimens is driving significant market expansion.
