Use the interactive on CTVNews.ca to track prices of popular grocery store items such as milk, eggs, cheese, and fruits and vegetables. Studies of severely ill patients found that many of them shared genetic variations that might have made them especially susceptible to the diseases progression. On the other hand, in older patients there is a smaller immune cell response to the virus, reflected in fewer differences in immune populations between COVID-19 patients and controls. Other studies have supported the theory that these cross-reactive T cells exist and may explain why some people avoid infection.
