Darwin Zerpa is among those who have fled to Peru to get the antiretrovirals he needs. Now he counsels others with the virus
By day it is one of Lima’s grandest squares. By night the Plaza San Martín becomes a magnet for nightclubbers and bag-snatchers, as well as a haunt for male sex workers and their clients.
It is here just before midnight that 29-year-old Darwin Zerpa and other volunteers set up shop. Pulling up in an out-of-service ambulance and folding out a table on the pavement, they mark out a spot where passersby can get HIV finger-prick test results in less than 10 minutes.
