 [ Symptoms ] my boy friend and i have been diagnosed with chlamydia he is re infected [ Disease ] hi i understand your concern its actually very rare to get reinfected by chlamydia without having sexual intercourse with a infected partner the tablet he took must have definitely worked at that time and it doesnt seem to be the issue here the organisms do remain in dormant stage in gut but these can get active only if his immunity falls down considerably i suggest that you should consult a doctor for sure
