What’s the difference between ‘pandemic’ and ‘endemic’?
LA TimesLong lines for coronavirus testing should be a distant memory by the time COVID-19 becomes an endemic disease. COVID-19 will never go away, infectious disease experts tell us, but the global health emergency it sparked will be over when the disease becomes “endemic.” That certainly sounds like something to look forward to. Endemic is related to two words we’ve come to know well: epidemic: an infectious disease outbreak that is spreading rapidly through a community. Unfortunately, there’s no easy formula for calculating how long it takes for a pandemic disease to transition to an endemic state, said Dr. Mike Ryan, executive director of the World Health Organization’s Emergencies Program. “Endemic does not mean it’s not dangerous,” said Dr. Maria Van Kerkhove, the WHO’s technical lead on COVID-19.“We will continue to see outbreaks among susceptible populations.” Jennifer Nuzzo, an infectious diseases expert at the Johns Hopkins Center for Health Security, agreed that the coronavirus will be keeping us on our toes for the foreseeable future.
