Scientists revealed that the Alpha variant has a significantly higher reproduction number and causes a more severe infection with a higher mortality rate than the original strain. B.1.617.2 lineage is known as the Delta variant and falls under the category of VOC. This variant was first reported in India in October 2020. It has higher ... [Read More]

- Scientists from the Centers for Disease Control and Prevention on Friday took aim at the question of whether the Delta variant of the coronavirus causes more severe disease, finding no significant differences in the course of hospitalized patients’ illnesses during the Delta wave compared to earlier in the pandemic.
