What is tested by the Schick test?

Diphtheria is a common infectious disease in India. Diphtheria is an acute communicable disease that affects the nose, throat, and tonsils. The bacilli multiply at the site of implantation (insertion into the body), be it the throat, nose, or tonsils. It produces local lesions at the site of implantation. This lesion is characterized by the formation of a patch or patches of greyish false-membrane on the affected parts such as the tonsils or larynx (voice box). It also produces an offensive and strong odor.
