i could criticize the randomness of the study, but the results seem to be consistent with the general picture - there's far more spread than has been measured by testing, but british columbia's sort of unique geographic breakdown, where pretty much every region is naturally isolated, makes it well suited to prevent widespread community spread without much intervention from the authorities. the okanagan valley is it's own thing, the island is it's own thing, the city is it's own thing - and there are oceans and mountains separating them.

as i've stated previously, measuring low immunity in a population suggests that it is still at high risk of a substantive outbreak. so, it could be argued that a targeted release may be beneficial to help build immunity - or, at the least, that it may benefit british columbians in the long run to facilitate the spread somewhat in the healthy population. but, if it's been kept low this long by the geography, what reason is there to think the geography won't continue to act as a buffer? yet, if so, what are the benefits of maintaining restrictions?

that said, i'd suspect that kelowna probably has higher prevalence than vancouver, and that testing there may reveal higher immunity. i've been through the region, and i know that the cultural differences between lifestyles in kelowna and lifestyles in vancouver suggest that kelowna is the more likely vector, and place to pay closer attention to in terms of a likely serious outbreak. vancouver is an upper middle class city full of highly educated professionals, whereas kelowna is a large town full of agricultural labourers, many of whom live in tents over the summer and party pretty hard over night. wild sex parties involving multiple partners outside in the woods seems to be a normal part of the okanagan valley lifestyle. i would be baffled to find out that these people are observing any sort of distancing at all.

whatever the reason for it, bc does seem to have been unusually successful in stopping the spread of the virus, yet at the expense of remaining unusually vulnerable. so, now what? it consequently remains to be seen, in the end, if that is to it's benefit or not.
