Summary

COVID-19 is a respiratory tract disease caused by the SARS-CoV-2 virus, primarily spread through respiratory droplets and person-to-person contact. Symptoms include headache, fatigue, cough, and muscle aches, with severe cases leading to pneumonia, acute respiratory distress syndrome, and death. The virus has undergone several mutations, with the Omicron variant being less severe but more infectious. Long-term sequelae, known as Long COVID, affect 4.5% of cases, with varied symptoms involving multiple organ systems. Natural immunity lasts up to 1 year, but new strains can cause reinfection. The pandemic was first reported in Wuhan, China in 2019, with over 600 million cases worldwide as of October 2022. In the UK, successive variants have emerged, with the Omicron sub-lineage being the dominant strain. Children are generally asymptomatic or develop mild disease, with severe cases and deaths being rare.
