The global infectious disease molecular diagnostics market was valued at USD 16.24 billion in 2024 and is projected to reach USD 20.15 billion by 2030, expanding at a CAGR of 3.4% from 2025 to 2030. This growth is primarily driven by the rising global prevalence of infectious diseases.

According to the World Health Organization, as of January 22, 2025, more than 5,000 chikungunya virus disease (CHIKVD) cases and two deaths were reported across four countries worldwide. In 2024, a total of 620,000 cases and 213 deaths were documented, mostly in the Americas, with Brazil, Paraguay, and Argentina experiencing the highest infection rates. In Asia, India and Pakistan reported significant numbers of cases, while Senegal remained the only affected country in Africa. Europe recorded one locally transmitted case in France and 118 cases in La Réunion. Beyond chikungunya, persistent public health threats such as HIV/AIDS, tuberculosis, hepatitis, and respiratory infections continue to elevate the demand for advanced molecular diagnostic tools. Additionally, the growing elderly population contributes to increased diagnostic testing, as older individuals are at greater risk of infection.

Technological advancements have significantly enhanced molecular diagnostics, making testing more accurate, faster, and accessible across healthcare settings. For example, in January 2025, French startup AlterDiag partnered with the Institut Pasteur to develop rapid diagnostics for infectious diseases using single-domain antibodies and immunochromatography. The collaboration aims to improve or introduce point-of-care testing for WHO-priority pathogens. Cutting-edge methodologies—including Polymerase Chain Reaction (PCR), nucleic acid amplification, and next-generation sequencing—have dramatically improved pathogen detection precision and reduced turnaround times, enabling timely treatment and more effective disease control.
