Article Synopsis
- The COVID-19 pandemic has presented major health challenges, particularly with the emergence of new SARS-CoV-2 variants throughout multiple waves of infection.
- A study conducted in southern Bahia, Brazil, analyzed samples from two waves in late 2021 and 2022, revealing a significant increase in positivity rates and a shift from the Delta variant in 2021 to the Omicron variant in 2022.
- Differences in clinical symptoms were noted, with anosmia/ageusia being common in 2021 but less frequent in 2022, and other symptoms like fever and cough being more prevalent in Omicron infections compared to Delta.
