answer to Question 4 B. resistant strains are numerous
No. Because HIV mutations
happen frequently by chance, an untreated person infected
with HIV will have a number of different strains of the
virus, some of which may be naturally resistant to
different antiretroviral drugs. However, before treatment
is started, mutant (resistant) viral strains are
uncommon, and the natural (wild-type) strain predominates
because it replicates much faster.
