Therefore three secretaries have been directed to make an on-site visit and review COVID-19-related management system," the order said.The officers have also been told to communicate with health and family welfare department secretary N B Dhal before leaving for their destinations.The number of coronavirus patients in the three districts have spiked to 27 from six, in matter of just 72 hours, a senior official said.Most of those affected were found to have links with West Bengal, he said, noting that a survey has revealed that 3,000 people from the neighbouring state had recently entered these three districts, the official said.Earlier, the health department had sent experts from medical colleges, directors of Health Service, Public Health and Family Welfare, along with Rapid Response Teams (RRTs), to oversee containment measures in these districts, he added.Meanwhile, police have tightened security along the Bengal border, sealing more than 50 roads leading to the neighbouring state. This apart, the marine police has been directed to ensure that no one enters Odisha via sea route, he added.
