SARS-CoV-2 is the virus responsible for the COVID-19 pandemic that began in late 2019. Research on SARS-CoV-2 includes studying the virus's transmission, symptoms, and impact on human health, as well as developing vaccines and treatments to combat the virus. Scientists are also investigating how the virus mutates and evolves over time, as well as how to prevent future pandemics caused by similar viruses. The research on SARS-CoV-2 is crucial in helping to control the spread of COVID-19 and ultimately bring an end to the pandemic.
