SARS-CoV-2 (Covid-19)

[ kow-vuhd nine-teen ]

SARS-CoV-2 is a virus that belongs to the coronavirus family and is responsible for causing the COVID-19 disease. It is an enveloped virus with a single-stranded RNA genome. SARS-CoV-2 is highly contagious and primarily spreads through respiratory droplets when an infected person coughs, sneezes, talks, or breathes heavily. The virus enters the body through the respiratory tract, where it attaches to and enters human cells using a specific receptor called ACE2. Once inside the cells, the virus replicates and spreads throughout the body, leading to the manifestation of COVID-19 symptoms. Extensive research and scientific efforts have been focused on understanding and combating SARS-CoV-2 to control the COVID-19 pandemic.
