Snippet: Whether a selective advantage at either scale results in the mutant reproductive number R m exceeding one depends on the duration of the infection. For short-term infections, most transmissions occur towards the end of the infectious period T , when the infectious load is the highest. By the end of the infectious period, the mutant viral density has increased approximately by a factor of e sT more than the wild-type, and transmission for each mut.....
Document: Whether a selective advantage at either scale results in the mutant reproductive number R m exceeding one depends on the duration of the infection. For short-term infections, most transmissions occur towards the end of the infectious period T , when the infectious load is the highest. By the end of the infectious period, the mutant viral density has increased approximately by a factor of e sT more than the wild-type, and transmission for each mutant virion is exp(Ï„ ) more likely than for a wild-type virion. Refining this intuition, we derive the approximation (Appendix)
