Most long COVID-19 sequelae affect people under 65, finds study As hundreds of thousands of people continue to become infected with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), leading to coronavirus disease 2019 (COVID-19), a significant minority will develop severe disease, and about 1% will die. However, many more who recover from the acute infection will have persistent symptoms and debility. This sequalae, encompassing a range of different post-viral complications, has come to be known as “long covid.” A new study, released as a preprint on the medRxiv* server, discusses the typical symptoms and signs of this syndrome, with the intention of improving the specificity of detection and reporting.
