As Canadian public health officials question China's transparency in sharing its COVID-19 surveillance information, scientists are stepping up airplane wastewater testing to try to get an early warning of potential new variants. On Friday, Vancouver International Airport will join Toronto's Pearson International Airport in taking samples of fecal matter that came from airplane toilets to identify what coronavirus variants and subvariants passengers and crew might be bringing into Canada.
EU urges more checks for COVID variants given surge in China
The European Union should consider immediately scaling up genomic sequencing of COVID-19 infections and monitoring of waste water, including from airports, to detect any new variants given the virus surge in China, the bloc's health chief said. In a letter to health ministers of the EU's 27 members, Stella Kyriakides said the bloc should be "very vigilant" as China lifted travel restrictions on Jan. 8 as reliable epidemiological and testing data for China were quite scarce.
