Public health mitigation of COVID-19
Measures to halt the spread of the respiratory disease among populations / From Wikipedia, the free encyclopedia
Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about Public health mitigation of COVID-19?
Summarize this article for a 10 year old
Part of managing an infectious disease outbreak is trying to delay and decrease the epidemic peak, known as flattening the epidemic curve.[1] This decreases the risk of health services being overwhelmed and provides more time for vaccines and treatments to be developed.[1] Non-pharmaceutical interventions that may manage the outbreak include personal preventive measures such as hand hygiene, wearing face masks, and self-quarantine; community measures aimed at physical distancing such as closing schools and cancelling mass gathering events; community engagement to encourage acceptance and participation in such interventions; as well as environmental measures such surface cleaning.[5] It has also been suggested that improving ventilation and managing exposure duration can reduce transmission.[6][7]
During early outbreaks, speed and scale were considered key to mitigation of COVID-19, due to the fat-tailed nature of pandemic risk and the exponential growth of COVID-19 infections.[8] For mitigation to be effective, (a) chains of transmission must be broken as quickly as possible through screening and containment, (b) health care must be available to provide for the needs of those infected, and (c) contingencies must be in place to allow for effective rollout of (a) and (b).[citation needed]
By May 2023, in most countries restrictions had been lifted and everyday life had returned to how it was before the pandemic due to improvement in the pandemic's situation.[9][10]
