Some early studies suggest 10% to 20% of people with COVID-19 will experience symptoms lasting longer than a month. A majority of those who were admitted to hospital with severe disease report long-term problems including fatigue and shortness of breath. On 30 October 2020 WHO chief Tedros has warned that "to a significant number of people, the COVID virus poses a range of serious long-term effects". He has described the vast spectrum of COVID-19 symptoms that fluctuate over time as "really concerning." They range from fatigue, a cough and shortness of breath, to inflammation and injury of major organs – including the lungs and heart, and also neurological and psychologic effects. Symptoms often overlap and can affect any system in the body. Infected people have reported cyclical bouts of fatigue, headaches, months of complete exhaustion, mood swings and other symptoms. Tedros has underlined that therefore herd immunity is "morally unconscionable and unfeasible...

Some newspaper agencies removed their online paywalls for some or all of their coronavirus-related articles and posts, while scientific publishers made scientific papers related to the outbreak available with open access. Some scientists chose to share their results quickly on preprint servers such as bioRxiv. Misinformation

Screening is done with a device such as a thermometer to detect the elevated body temperature associated with fevers caused by the coronavirus. Containment is undertaken in the early stages of the outbreak and aims to trace and isolate those infected as well as introduce other measures to stop the disease from spreading. When it is no longer possible to contain the disease, efforts then move to the mitigation stage: measures are taken to slow the spread and mitigate its effects on the healthcare system and on society. A combination of both containment and mitigation measures may be undertaken at the same time. Suppression requires more extreme measures so as to reverse the pandemic by reducing the basic reproduction number to less than 1. Part of managing an infectious disease outbreak is trying to delay and decrease the epidemic peak, known as fla...
