Background: The information on the pathophysiology of infection in high-risk contacts of SARS-CoV-2 is limited. Aims: The aim of the present study was to assess the various factors and their elucidation in the protection of SARS- CoV-2 infection in high-risk contacts. Settings and Design: Cross-sectional descriptive clinical study. Materials and Methods: A total of 136 subjects were recruited in the present study including 100 high-risk subjects and 36 control subjects. Out of 100 high-risk subjects, 44 subjects were found positive for SARS-CoV-2 RNA. Further, absolute blood counts of total T-cells (CD3+), T-helper cells (CD4+), T-cytotoxic cells (CD8+), B lymphocytes (CD19+) Natural Killer (NK) Cells (CD16+, CD56+), cytokines, and other parameters were measured in the samples of study subjects. Statistical Analysis Used: The continuous variables were analyzed by unpaired 't' test, analysis of variance and 'Tukey test' for multiple comparisons. Results: A significant reduction of total leukocyte counts and absolute lymphocyte count was found in the acute SARS-CoV-2 positive group as compared to control group (
