text: It depends upon the diseases status....Like in all common diseases you can keep body as long as you wish (ofcourse you must not overlook the legal implications of it)....but in some diseases like Plague, very contagious diseases, AIDS related complex etc you need to dispose the body soon. However even in the later cases, if you do proper embalming, then you can delay its burrial...........\nBut I am really surprise as what made you interogate into such an issue...Anyway don't fall for any crime ..ok..and take care.
