Covid-19

Through illness, community and national lockdowns, and economic downturn, the COVID-19 pandemic has upended the lives of millions of people worldwide. At Britannica we have been fielding questions about the pandemic from readers, and we’ve had a few questions of our own. Here are answers to some of our readers’ and our own questions about the COVID-19 pandemic.

Understanding Pandemics

A pandemic is an outbreak of infectious disease that occurs over a wide geographical area and that is of high prevalence. A pandemic generally affects a significant proportion of the world’s population, usually over the course of several months. Throughout history, humanity has survived several pandemics. While this global health crisis continues to evolve, it can be useful to look to the past to help us understand our possible future.

What can previous pandemics teach us about our response today?

Misinformation about COVID-19 is dangerous, and the falsehoods related to COVID-19 raise serious public health and safety.

Although it may feel like all the news is bad regarding the COVID-19 pandemic, there are a few positive stories to share. For example, efforts to relieve hospitals’ shortages of masks, respirators, and other supplies have come from some of the most unlikely places.

The incubation period for a disease can be determined in several ways. Generally, however, it is calculated as the time from a known exposure incident to the infectious agent until onset of symptoms.
Sparking national conversations
From national emergencies to government aid and statewide curfews, COVID-19 has changed the national conversation as we know it. It has provoked a global discussion and questions about our healthcare systems, how we diagnose, how we work, how we educate, and so much more.  
COVID-19 emergency resources now available to every school
 Over the past two months, Britannica has been working with our partner schools across the world who are grappling with COVID-19 school closures and student absences and making swift plans to keep their communities safe. As schools across the United States implement and prepare for school closures to prevent the spread of COVID-19 in their communities, we want to ensure that you are aware of the free emergency support and virtual-learning classroom resources Britannica has made available to every school.
