The coronavirus disease-2019 (COVID-19), which caused loss of massive lives and is still continuing to do so, was initially observed to cause severe illness and deaths in Wuhan (China) around December of 2019. The virus spread at a very fast pace all around the world extensively which made the World Health Organization (WHO) to declare a pandemic on March 11, 2020. Contract tracing is an effective method for containment of infectious like coronavirus disease. It is a method in which a lead case with confirmed COVID infection is enquired about the people he contacted during the period when he was possibly infective as the contacts were at a very high risk of obtaining infection from the lead case. The contacts are then traced and counseled about the risk of infection, quarantined, and tested if necessary as per the countries testing guidelines. Contact tracing is an efficacious method which can prevent the transmission of infection by identification of infected individuals, their isolation and care depending upon the severity of the disease (home isolation/hospitalization), and also investigation of the individuals which were exposed to them and isolating them for the required period if necessary so that virus transmission can be stopped. To conclude, contact tracing is definitely an important measure to control, prevention as well as the spread of coronavirus disease as respiratory droplets are the main form of spread of the virus. It is equally effective against all the strains of the virus irrespective of its virulence.
