Researchers found that omicron subvariants are evolving different tissue preferences. XBB.1.5 and EG.5.1 replicated more efficiently in respiratory tissues, while BA.2.86 and JN.1 showed stronger replication in small-intestine models. The findings suggest SARS-CoV-2 may be diversifying toward distinct respiratory and gastrointestinal transmission strategies. https://www.nature.com/articles/s41467-026-74111-y
