Infectious Disease Diagnostics Market Summary
Introduction
Infectious disease diagnostics encompass advanced technologies designed to detect and identify pathogens, including bacteria, viruses, fungi, and parasites, enabling timely diagnosis and management of diseases such as COVID-19, tuberculosis, HIV, and hepatitis. These diagnostics, including immunodiagnostics, polymerase chain reaction (PCR), and next-generation sequencing (NGS), are critical in diagnostic laboratories, hospitals, clinics, and research institutes. The market is driven by the rising global burden of infectious diseases, with over 1.5 billion cases of respiratory infections annually, and the increasing demand for rapid, accurate testing to combat outbreaks and antimicrobial resistance. Factors such as growing awareness of early diagnosis, advancements in molecular diagnostics, and the integration of point-of-care (POC) testing further propel market growth, particularly in response to pandemics and emerging pathogens.
