This study consists of 56 carcinoma cases of the oral cavity and oropharynx, 56 controls matched for age, sex, and habits, and 100 other controls proportionate to the population of Karachi.

The Enzyme Immunosorbent assay (EIA) of sera revealed significantly high levels of anti HSV-I IgG and IgM antibodies in carcinoma cases (96.43% and 25.00%, respectively) when compared with matched controls (73.21% and 3.5%, respectively).
