This week, the Centers for Disease Control and Prevention officially declared the Delta variant, a coronavirus strain first detected in India, “a variant of concern.” This designation is given to variants shown to be more transmissible than the original strain, that can cause more severe disease and potentially reduce the effectiveness of treatments or vaccines.
