  • Coronavirus tests: researchers chase new diagnostics to fight the pandemic

    Nature examines how viral diagnostic tests work, why testing has varied around the world and the CRISPR-based tests under development to fight COVID-19.

    Diagnostic tests for COVID-19 have loomed large in the ongoing coronavirus pandemic as an essential tool to track the spread of the disease.

    • Fast, portable tests come online to curb coronavirus pandemic Testing kits delivered by courier and digital tools combine to battle the COVID-19 outbreak. The extraordinary success of Singapore, Taiwan and Hong Kong in limiting the impact of the sudden acute respiratory syndrome coronavirus-2 (SARS-CoV-2) demonstrates that it is possible to mount an effective response to an outbreak by major investment in pandemic preparedness. Despite their proximity to China, these three regions have managed to keep case numbers and fatalities low. By learning from previous coronavirus outbreaks where these territories bore the brunt, they were able to rapidly deploy widespread testing, combine it with digital surveillance to trace individuals’ movements, and impose strict quarantines in suspect cases, in addition to building large stockpiles of personal protective equipment.

    • The standard coronavirus test, if available, works well—but can new diagnostics help in this pandemic? By Robert F. ServiceMar. 22, 2020 , 12:15 PM As the United States races to ramp up testing for the pandemic coronavirus using technology based on the tried-and-true polymerase chain reaction (PCR), alternative approaches are beginning to roll out that could make it easier and quicker for people to learn whether they have been infected. Some methods modify the standard PCR test, which amplifies tiny bits of genetic material to enable detection, while others sequence the virus directly or use the genome editor CRISPR.
