Infectious diseases are a major global public health problem. Multiple agents are now recognized to cause indistinguishable illnesses. The term ‘syndrome’ applies to such situations, for which early and rapid diagnosis of the infecting agent would enable prompt and appropriate therapy. Public health physicians would also get timely information on the specific etiology of the infectious syndrome, facilitating intervention at the community level in the face of outbreaks or epidemics. A variety of molecular techniques have been evaluated for rapid diagnosis of infectious syndromes. These techniques include real-time multiplex PCR, DNA microarray, loop-mediated isothermal amplification, and other similar assays. This review surveys such state-of-the-art technologies.
