The COVID-19 virus, caused by the SARS-CoV-2 virus, is a highly contagious respiratory illness that emerged in late 2019. It primarily spreads through respiratory droplets when an infected person coughs, sneezes, or talks. Symptoms can range from mild to severe and may include fever, cough, and difficulty breathing. To combat the spread of COVID-19, public health measures such as wearing masks, practicing social distancing, and frequent handwashing have been recommended. Vaccines have also been developed and distributed globally to help protect individuals and communities from severe illness and reduce transmission rates.
