Hello Ishu,

Preparing for D. M. Infectious disease in AIIMs is really tough and you need to practice questions thoroughly. Virology & Parasitology as well as Bacteriology including TB & Leporasy, pyrexia of unknown origin and their differential diagnosis along with different forms of infectious diarrhoea and pneumonia which ultimately covers the whole Microbiology are to be practiced. The syllabus range could not be even predicted. Questions will be application or clinicaly based.  This also includes latest modalities in the diagnosis and molecular diagnosis of biological and parasitological diseases. You would have 90 minutes for 80 MCQs, you need to just practise these related questions. If you want to gain more than or equal to 50 Percentile, you need to know basics of theory as well as practical.  You must also be aware of the basic procedures of culture in autoclave and along with serological tests, identification of various microbiological specimens and instruments and some readymade tests done for which you have to interpret the result.  You also need to go through Journals to get updated information.
