People with long COVID, or post-COVID condition, have ongoing symptoms that can range from chest pain, trouble breathing and fatigue, to brain “fog,” loss of smell or taste, anxiety and depression — long after their COVID-19 infection has cleared. Almost two years into the pandemic, most questions about these “long-haulers” remain unanswered: Why do about one in 10 COVID-19 patients exhibit ongoing symptoms? What causes it? Why is it more severe than other post-viral syndromes?
Today in The Conversation Canada, Manali Mukherjee and Zain Chagla of McMaster University write about what’s known about long COVID, and what isn’t. “One theory we and our colleagues are exploring through research is that COVID-19 triggers such a powerful immune response that it may not be the virus that is directly responsible for long COVID, but our bodies’ response to it.”

Our society has never explicitly debated whether the health-care industry is more important than other critical sectors, like education, as governments impose lockdowns.

If Vallée’s films are so moving, it is because for him, cinema and television are an act of communication. He said he hoped his stories would “give back a little.”

Today, teens are often seen as troublesome and difficult. Ancient Roman writers also described adolescence as a period of “hooliganism and debauchery.”

Teens across millennia have yearned to explore, try new things and participate in risky behaviours. The key difference, however, seems to be the experience of a rebellion or restlessness.
