I am back on line. I was not in Rwanda, and it was not easy for me to be connected. I am happy to reading again your interesting discussions, I was missing that. I totally agree with you all, engaging community in early stage, is the best way to avoid confusion and misunderstandings, eventually, it increase more trust between Researchers and Community, it provide freedom to communicate effectively and do move out any concerns that one of them may have during the study. as every one get time to raise he/her questions before hand and have clear image or situation earlier. So let support that idea of involving earlier stage, because we all benefit from it. Working in harmony, we always get a positive result .
