Omicron was found in Nova Scotia wastewater weeks before it was discovered by the province and even before the novel COVID-19 strain was reported by South Africa, according to new research from Dalhousie University in Canada.
Explaining the situation, Professor Graham Gagnon, director of the Dalhousie University Centre for Water Resource Studies, said that "Our team detected Omicron , retrospectively, in Nova Scotia wastewater in mid-November and will be able to provide further information in the future."
