R Rajesh Kumar, health secretary of Uttarakhand, said, "Three people have tested positive in the state. None of them are residents of Uttarakhand. They were found positive upon arrival. It suggests that we have a robust system in place. We are exercising surveillance and monitoring the situation closely, given the fact that a large number of people are visiting the state for the Char Dham yatra." He added that all district magistrates (DMs) have been directed to maintain surveillance, following guidelines from the Union health ministry. According to Kumar, one of the three Covid-positive individuals is a resident doctor at the All India Institute of Medical Sciences (AIIMS), Rishikesh, and is currently in isolation. "One of three patients has already left the state. The other two are undergoing treatment, and their condition is stable. There is no cause for concern," he said. Kumar clarified, "While we are maintaining surveillance, no specific advisories have been issued yet for the Char Dham yatra or other tourist destinations."
