Introduction: Contact tracing is an essential public health tool, which includes prompt and rapid identification of potentially infected individuals before the emergence of severe symptoms.
Objective: The objective of this cross-sectional analysis was to highlight a targeted prevention strategy for the spread of disease by monitoring rigorous contact tracing.
Study design: A retrospective cross-sectional analysis.
Study setting: Tertiary care hospital.
Patients/participants: Health care workers of a tertiary care hospital.
Methodology: An analysis of information provided in the contact tracing of 30 diagnosed coronavirus disease 2019 (COVID-19) positive patients was done in the present study. The study duration ranged from April to December 2020 and was conducted among the diagnosed COVID-19-positive patients of the Center for Dental Education and Research (CDER), All India Institute of Medical Sciences (AIIMS), New Delhi. Ethical approval was obtained from the Institutional Ethics Committee (IEC-1079/06.11.2020). The retrospective contact tracing was done for a period of 48 hours prior to the time of diagnosis or the time of first reported symptoms, whichever was earlier, by a trained medical professional.
Results: Fever (76.7%) was the most common symptom found at the time of diagnosis among the cases. It was found that the high-risk contacts (20%) were more susceptible to developing a COVID-19 infection compared to their low-risk counterparts (2%).
Conclusion: Aggressive contact tracing, when done right, is tremendously effective in containing an outbreak. Overstretched contact tracing can clearly diminish the possibility of the creation of a hot spot.
