How will the world decide when the pandemic is over?
India TodayThere’s no clear-cut definition for when a pandemic starts and ends, and how much of a threat a global outbreak is posing can vary by country. It’s about severity and it’s about impact,” says Dr. Michael Ryan, the World Health Organization’s emergencies chief. In January 2020, WHO designated the virus a global health crisis “of international concern.” A couple months later in March, the United Nations health agency described the outbreak as a “pandemic,” reflecting the fact that the virus had spread to nearly every continent and numerous other health officials were saying it could be described as such. “There is not going to be one day when someone says, ‘OK, the pandemic is over,’” says Dr. Chris Woods, an infectious disease expert at Duke University. Scientists expect COVID-19 will eventually settle into becoming a more predictable virus like the flu, meaning it will cause seasonal outbreaks but not the huge surges we’re seeing right now.
