In late 2019, health officials noticed a new disease spreading in Wuhan, China. They named it COVID-19. Within a few months, it became a pandemic that dramatically changed life for nearly everyone on Earth. Millions of people became sick, and hundreds of thousands died. Leaders ordered whole states and countries to stay home to slow the disease’s spread. Companies closed or went out of business. Meanwhile, health-care workers on the front lines saved lives and raced to find treatments. In the Core Library Guide to COVID-19, readers will learn about the disease, how it spread across the globe, and the ways it has changed society. As the COVID-19 pandemic spread, the phrase flatten the curve became widely known. It refers to the things people can do to space the total number of infections out over a longer period of time. This helps prevent the health-care system from being overloaded. Flattening the Curve examines social distancing and the other measures that people took to slow the spread of the disease. Features include a glossary, references, websites, source notes, and an index. AGES: 9 to 11
