Coronavirus disease (COVID-19) technical guidance: Laboratory testing for 2019-nCoV in humans
In areas with no known SARS-cov-2 infections:
To consider a case as laboratory-confirmed by nucleic acid amplifaction tests (NAAT) in area with no known COVID-19 virus circulation positive , one of the following conditions needs to be met: NAAT result for at least two different targets on the COVID-19 virus genome, of which at least one target is preferably specific for COVID-19 virus using a validated assay (as at present no other SARS-like coronaviruses are circulating in the human population it can be debated whether it must be COVID-19 or SARS-like coronavirus specific);
OR: One positive NAAT result for the presence of betacoronavirus, and COVID-19 virus further identified by sequencing partial or whole genome of the virus as long as the sequence target is larger or different from the amplicon probed in the NAAT assay used.
In areas where COVID-19 virus is widely spread a simpler algorithm might be adopted in which, for example, screening by rRT-PCR of a single discriminatory target is considered sufficient.
