Delta variant (SARS-CoV-2)

The Delta variant is a version of the SARS-CoV-2 virus that causes COVID-19, which has changes in its genetic code making it more contagious than earlier strains. It spreads more easily, leading to quicker outbreaks and higher numbers of infections. This variant can cause more severe illness and has shown some resistance to vaccines, though vaccines still provide significant protection. Public health measures like vaccination, wearing masks, and good hygiene remain essential to control its spread. Overall, Delta emphasizes the importance of adapting strategies to manage evolving virus variants effectively.
