The Evolution of SARS-CoV-2 Delta and Omicron Variants: Transmission Dynamics and Public Health Response

Conducted an independent literature review analysing the epidemiological and virological differences between the SARS-CoV-2 Delta and Omicron variants. Examined global transmission dynamics across major world regions, evaluated country-level public health strategies including vaccination campaigns, non-pharmaceutical interventions, and surveillance frameworks, and identified critical gaps in global genomic sequencing capacity. Developed original data visualisations including variant case trajectory charts, a comparative schematic of variant characteristics, regional transmission maps, and a public health response timeline.
