Nested case-control study of health workers exposed to confirmed COVID-19 patients.
Similar objectives to the cohort study but case-control studies may be cheaper and provide robust evidence to characterize and assess the risk factors for SARS-CoV-2 infection in health workers exposed to COVID-19 p...atients.
Health workers with confirmed COVID-19 will be recruited as cases and other health workers in the same health care setting without infection will be recruited as controls (incidence density sampling).
Secondary objectives are similar to the cohort study.

The speed of developing diagnostics for SARS-CoV-2, the causative agent of coronavirus disease 2019 (COVID-19), has been quite remarkable. Diagnostics have focused on nucleic acid amplification testing (NAAT) to identify infected individuals in acute-phase disease for timely implementation of mitiga...tion strategies and case management. More and more immunodiagnostics, mostly rapid diagnostic tests, are being made available as an alternative to NAATs. This type of test can be used out-of-laboratory conditions at large scale.

The document titled "Manual for Stratifying Malaria Risk and the Elimination of Foci" by PAHO provides guidance for countries in the Americas on how to systematically assess and classify malaria transmission risk at subnational levels. It outlines a standardized approach to stratification and the id...entification of active transmission foci, helping public health authorities prioritize interventions, allocate resources efficiently, and implement targeted strategies to accelerate progress toward malaria elimination.
