Hi, I Have A Couple Questions About Trichomoniasis...here Is The

Hi, I have a couple questions about trichomoniasis...here is the scenario, a man and woman have both been treated at the same exact time for Trich. Then the same woman popped up with it again 4 weeks later. The man goes and gets tested and is negative, as is the new woman he is now sleeping with. The original woman is claiming that it came from the original man, is that possible?
