The effectiveness of contact tracing in mitigating COVID-19 outbreak: A model-based analysis in the context of India

作者:

Highlights:

• A new mathematical model of transmission of the COVID-19 disease is proposed.

• Two disease control policies namely, contact tracing and isolation are considered.

• An optimal control problem is framed to measure the efficacy of contact tracing.

• The model is calibrated with the data from the six most affected states of India.

• A short-term prediction is given with possible variation in contact tracing level.
