SARS Coronavirus, also known as SARS-CoV, is a virus that causes severe acute respiratory syndrome (SARS). It was first identified in China in 2002 and led to a global outbreak in 2003. The virus primarily spreads through respiratory droplets when an infected person coughs or sneezes, affecting the lungs and causing symptoms like fever, cough, and difficulty breathing. SARS-CoV is part of the larger family of coronaviruses, which also includes MERS-CoV and SARS-CoV-2, the virus responsible for the COVID-19 pandemic. While SARS was contained relatively quickly, it highlighted the potential for coronaviruses to cause serious health crises and emphasized the importance of global surveillance and response systems.
