COVID-19 Variants

COVID-19 Variants refer to the various strains of the SARS-CoV-2 virus that have emerged since the onset of the global pandemic in late 2019. These variants occur due to mutations in the virus's genetic code, which can alter its characteristics, such as transmissibility, severity, and resistance to vaccines or treatments. Understanding and monitoring COVID-19 variants is critical for public health efforts to control the spread of the virus and adapt response strategies accordingly. Research continues to identify and analyze these variants to inform vaccine updates and preventive measures to safeguard public health against evolving strains.
