You are doing a great job for your villager, i appreciate it.
Your villager is free of syphilis
now but he had a infection once in his life time.
TPHA test result become positive 4-6 weeks after primary infection of syphilis but can remain positive for 20-30 years or even lifelong. so it needs no treatment or any frustration.
TPHA or RPR test is not a indicator of HIV/AIDS
If your villager has any confusion he can go pathology
and do ELISA
for HIV test.
