"Detection of Co-Infections and Recombination in 2 Million SARS-CoV-2 Samples"
A recent study published in Nature Communications analyzed over 2 million SARS-CoV-2 samples to detect co-infections and intra-host recombination, identifying 7700 co-infection samples with a 0.35% rate and potential recombinant strains, particularly involving common variants like Delta and Omicron. The study's robust approach offers insights into the dynamics of viral co-infections and recombinants, emphasizing the need for systematic global surveillance to capture the complexities of SARS-CoV-2 evolution accurately.
