"Flattening the curve" refers to the effort to slow the spread of a disease, such as COVID-19, to prevent overwhelming healthcare systems. When a disease spreads rapidly, many people may become sick at the same time, leading to a shortage of hospital beds, medical staff, and resources. By implementing measures like social distancing and vaccination, the number of cases can be spread out over a longer period. This approach helps ensure that hospitals can provide adequate care for all patients. A flatter curve means fewer people are sick at once, allowing healthcare providers to manage resources effectively and improve patient outcomes.
