“The survey is currently in its first phase and is a door-to-door exercise. As of Monday, we surveyed 3,55,959 homes. Of them, 13,367 have been found to have larvae,” Dr Devaki told Express.
She added that every house that had dengue larvae was marked as D+. “We did this so that in the second phase of the survey we can concentrate only on D+ homes,” she said.
