SANTAELLA-TENORIO, Julián. SARS-CoV-2 diagnostic testing alternatives for Latin America. Colomb. Med. [online]. 2020, vol.51, n.2, e4272.  Epub 11-Maio-2020. ISSN 1657-9534.  https://doi.org/10.25100/cm.v51i2.4272.

In the past four months SARS-CoV-2 has reached most countries in the world. Public health strategies based on widespread testing and proper isolation of positive cases have shown to be helpful to reduce local transmission of SARS-CoV-2. Confirmatory tests, that identify viral RNA, and screening serological tests that identify viral antigens or host antibodies against viral proteins are part of the tools that nations can use to fight infectious disease epidemics. Understanding how each test works can provide insights about their test characteristics and how they can be used for different clinical and public health goals. Testing is a key strategy to reduce viral transmission, not only for this epidemic, but also for others to come.
