Kristen Villebrun and Wendy Bush hoped they wouldn't have to pray for Chedoke Creek, but four years after they first raised alarm about the water's condition, they were part of an Indigenous full moon ceremony to do just that. About 50 people showed up near Princess Point on the dark and frigid Monday evening for the monthly ceremony, which was particularly special as it focused on Chedoke Creek.

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.
A dynamic surveillance system encompassing waste-water testing, representative population-based testing and genomics should be implemented to efficiently monitor pan-respiratory disease trends, rapidly detect resurgences and emergence of novel variants, and respond with tailored and effective public health programs.
