Abstract

Surveillance was instrumental in managing the COVID-19 pandemic. Various methods helped track cases, variants, and disease severity. In addition, the data aided authorities in identifying waves, gauging control measures, and estimating transmission rates. Genomic analysis tracked SARS-CoV-2 variants, and hospital surveillance assessed health care impact. Despite low testing, wastewater monitoring caught outbreaks, but excess mortality showed unreported COVID-19 deaths. Household studies highlighted asymptomatic transmission and vaccination?s importance. Serosurveys revealed increasing immunity across waves. Emerging variants, like Omicron, demonstrated the virus?s dynamic nature, emphasising the need for ongoing surveillance and global collaboration. The Delta variant strained South Africa?s health care systems, revealing vaccine rollout challenges. Disruptions to routine services occurred and were worsened by societal unrest. Vaccination efforts targeted high-risk groups, but hesitancy persisted due to safety concerns and misinformation. Advisory committee transparency and clear communication were vital. Overall, continuous surveillance, adaptive responses, and public cooperation were essential in managing the pandemic?s multifaceted challenges.
