The health department, police and telecom service providers are collaborating with each other in this effort,” said Gupta. Principal health secretary Nitin Madan Kulkarni said the police and health department officials have succeeded in contact tracing of the four positive cases, including the latest confirmed case from Ranchi. “We are using the technology at our hand with help of the police department to trace the contacts using mobile phones of the affected persons and we have achieved good success in this direction. “All mobile service providers store for a specific period data relating to the use of each mobile phone on their network including location information. This would allow contact tracing throughout the entire population, creating a more proactive way to track down suspected cases, the sources said.
