Personal biases warp COVID-19 memories, posing a challenge for future pandemic policies

In a series of studies, researchers found that personal biases significantly influence how individuals remember the COVID-19 pandemic, which could potentially shape historical narratives and impact future pandemic policies. They suggest that recognizing these biases is crucial for developing long-term strategies that maintain societal trust and cohesion.

Omicron variant BA.2.86 spreads faster, but current antivirals hold the line

Researchers discover the BA.2.86 Omicron lineage with higher transmission potential than current dominant strains, yet show that existing antivirals remain effective. Despite its higher infectivity, BA.2.86 exhibits lower pathogenicity in hamsters, indicating decreased replication capacity may lead to less severe infections.
