Dear colleagues.

I published this eBook as the initial volume of our "Comprehensive Review eBOOKS", specifically focusing on the topic of "Infectious Disease". This publication was a result of a collaborative effort with my highly skilled and enthusiastic coauthors, namely PharmDs Arwa Al-Ashqar, Dua'a Nayef Suleiman Alqhaiwi, Kariman Hatem Al Ghweiiri, Najd Khaled, and Raya Ashraf Alawaisheh. Our work involved thorough research and meticulous collection of evidence. In this series, we categorise each chapter into four sections: preface, multiple-choice questions with guiding answers, study points, and linked references. This eBook contains a total of 187 multiple-choice questions (MCQs) and their corresponding answers. Our primary areas of focus include medical, surgical, clinical pharmacy, and pharmacological specialists, as well as mentors, residents, and students.
