Mean primary transmissions per person among people who acquire HIV through age 30. Among people who acquire HIV by age 30, the graph presents the mean number of cumulative primary HIV transmissions by each year of age for each strategy. Comparing 3-monthly screening to Status quo, there was a 40% reduction (0.58 vs 0.98) in the mean number of primary transmissions at age 30. 3-Monthly screening led to the fewest projected transmissions.
