Rising COVID-19 positive cases in the city have made the task of contact tracing a challenging job. While it is comparatively easy to trace primary contacts, tracing the secondary contacts of patients is an uphill task.
Primary contacts include family members, close relatives and those at their workplaces. Secondary contacts usually include persons they have contacted in public spots including shops or markets. In some cases, the positive patients say that they neither have a travel history nor any contact with a positive person.
