Beschreibung
Zusammenfassung:	Provided herein is a method for detecting the presence of clade variants in the COVID-19 virus in a human sample and/or an environmental sample. Samples are processed to obtain total RNA. The RNA is used as a template in a combined reverse transcription and amplification reaction to obtain fluorescent COVID-19 virus amplicons. These amplicons are hybridized on a microarray with nucleic acid probes having sequences that discriminate among the various clade variants. The microarray is imaged to detect the clade variant. Also provided is a method of distinguishing each clade variant from others by generating an intensity distribution profile from the image, which is unique to each of the clade variants.
