Strengthening diagnostic services in Latin America requires regional leadership, sustainable funding, and enhanced data sharing

Diagnostic services played a key role in government responses to the COVID-19 pandemic. In our work to support diagnostics in over 20 countries of the Global South, with a focus on Latin America, we observed common problems in resource-limited settings. We identify common constraints of (i) affordability of reagents, (ii) access to reagents, (iii) poor infrastructure, and (iv) limited human resources. Enhancing diagnostic services in resource-limited settings cannot be sustained only by international cooperation and philanthropic missions. Success depends on domestic leadership and regional cooperation of which the existent influenza or dengue networks in Latin America are prime examples. A Latin American Center for Disease Control and Prevention (CDC), as proposed by some, can only be successful if reliable funding and a clear mandate are secured. A stronger inclusion of diagnostic tool development and data sharing will be imperative for dealing with emerging pathogens.
