COVID-19: Symptoms, Transmission, and Impact - Comprehensive Guide

COVID-19, also known as COVID-19, is a highly infectious disease caused by the SARS-CoV-2 virus. The virus was first identified in Wuhan, China in December 2019 and has since spread to become a global pandemic. COVID-19 primarily spreads through respiratory droplets when an infected person talks, coughs or sneezes. The symptoms of COVID-19 can range from mild to severe, and can include fever, cough, fatigue, difficulty breathing, and loss of smell or taste. The disease has had a significant impact on global health and the economy, leading to widespread lockdowns, travel restrictions, and economic downturns. Vaccines have been developed and are being distributed globally to help control the spread of the virus.
