Smoke from the wildfires raging in Washington state and Oregon has drifted north, prompting Environment Canada to issue a special air quality statement for Metro Vancouver. A live air tracker lists Vancouver's air quality as among the worst in the world, along with Portland and Seattle. So if you're feeling under the weather — how can you tell whether your symptoms are related to COVID-19, or a side effect of poor air quality? Centre for Disease Control, said that distinguishing between the two can be "tough," as many symptoms of COVID-19 and signs of irritation from smoke can be similar. Henderson said if you've experienced poor air quality before, it can be useful to compare your symptoms to ones you may have had previously.
