COVID-19 variants, especially that of Delta B.1.617, may not be enough to truly track its spread across the country, according to several experts.According to Dr.
Laurence Pelletier, a researcher from the Lunenfeld-Tanenbaum Research Institute at Mount Sinai Hospital, public health units across the provinces are, for the most part, not equipped with testing equipment that can fully sequence or identify some COVID-19 variants.One such variant of concern is that of the Delta B.1.617, which was first discovered in India.
Speaking with Global News Friday, both Pelletier and Mount Sinai co-researcher Dr. Jeff Wrana said that the number of mutations in the Delta variant made it very difficult for tests to properly identify it.
