We might absorb billions of viruses every day


In the experiment, just 0.1 percent of the total phages made it through. But based on their rate of travel, and the staggering number of them in the average human gut, the team estimated that our gut cells absorb around 31 billion phages every day. “The percentage feels like it can’t be that important but when you turn that percentage into absolute numbers, it feels biologically relevant,” says Corinne Maurice from McGill University, who also studies phages and was not involved in this study.
