A new study found that in some patients a resistance mutation to a particular drug appeared in a single virus particle, which then rapidly proliferated until the entire viral population within the patient consisted of its progeny and was also resistant to the drug. In other patients the same resistance mutation occurred in multiple viral particles within a short window of time, which led to a more heterogeneous, but still drug-resistant, viral population.
