The current work focuses on incorporating Randomized Response Techniques in Adaptive Cluster Sampling scheme for effective quarantining of COVID-19 suspected individuals, given the sensitive nature of the disease and people’s tendency to hide their symptoms. Estimators have been proposed for estimating the number of individuals in a population showing symptoms of COVID-19, the number of individuals in a population not wearing a mask and the optimal size of a quarantine cluster. The effectiveness of the proposed sampling strategy has been demonstrated through empirical studies. Based on the encouraging result, the proposed sampling strategy may be recommended to survey statisticians for their use in the battle against COVID-19 or similar contagious diseases.
