Rapid diagnostic test: a critical need for outbreak preparedness and response for high priority pathogens

Area of Science:

• Public Health
• Epidemiology
• Medical Diagnostics

Background:

• Rapid diagnostic tests (RDTs) are crucial for outbreak and pandemic preparedness, aligning with global initiatives like the 100 Days Mission.
• RDTs are essential for early case identification, surveillance, case management, and the deployment of vaccines and therapeutics.
• Current RDTs suffer from limited clinical sensitivity, specificity, and inadequate validation.

Purpose of the Study:

• To emphasize the critical role of RDTs in pandemic preparedness and response.
• To discuss the challenges in financing and investing in RDT development.
• To explore future avenues for supporting RDT advancement.

Main Methods:

• Literature review and analysis of current RDT landscape.
• Examination of funding mechanisms and investment trends in medical countermeasures.
• Discussion of policy implications and strategic recommendations.

Main Results:

• RDTs are pivotal for timely response but face significant limitations in performance and validation.
• Inadequate and inconsistent financing from public and private sectors impedes RDT development, especially for high-priority pathogens.
• The diagnostic industry has underinvested in RDTs, with vaccine development receiving disproportionately higher funding.

Conclusions:

• Sustained and adequate financing is essential for the development, validation, and implementation of RDTs.
• The Pandemic Fund presents a potential avenue for supporting diagnostic development.
• Parallel investment in diagnostics and therapeutics is necessary for comprehensive pandemic preparedness, not solely relying on vaccines.
