- Abstract
SARS-CoV-2, the cause of the COVID-19 pandemic, has introduced a challenging era characterized by the persistent emergence of subvariants. Even after the World Health Organization announced the end of the pandemic, the virus continues to evolve, posing significant challenges to public health responses. This comprehensive review examines the multifaceted impacts of these subvariants, emphasizing their significance across diverse dimensions. SARS-CoV-2 has genetic variability, especially at the spike protein region, which has given rise to Variants of Concern, including Beta, Delta, Gamma, Alpha, and the highly mutable Omicron, which differently exhibit varying levels of immune evasion, disease severity, and transmissibility. Subvariants within the Omicron lineage, including BA.1, BA.2, BA.3, and others, further complicate the landscape with distinct genetic signatures and varying infectivity levels. The impacts extend to diagnostic techniques, treatment strategies, and vaccine effectiveness, underscoring the need for a comprehensive public health response emphasizing preventive measures, genomic surveillance, and vaccination campaigns. Sustaining these interventions is critical, necessitating long-term strategies considering socio-political factors, community involvement, continuous adaptation of healthcare approaches, robust monitoring, and sustainable public health interventions to effectively combat the virus's ever-changing landscape.
