Amid rising concerns over the spread of omicron variant of coronavirus, Prime Minister Narendra Modi on Thursday stressed on Covid-appropriate behaviour, saying the fight against the pandemic is not over and directed officials to send teams to states with low vaccination, rising cases, and insufficient health infrastructure, to assist them in improving the situation.

Modi gave directions to officials during a high-level meeting to review the status of Covid-19 and Omicron, the new variant of concern (VOC), and said "we should be 'satark' (vigilant) and 'saavdhan' (cautious)".

The meeting was held to review the public health response measures for containment and management of Covid-19, strengthening of health infrastructure including availability of drugs, oxygen cylinders and concentrators, ventilators, PSA plants, ICU/oxygen supported beds, human resources, IT interventions and status of vaccination, the Prime Minister's Office (PMO) said in a statement.

Officials briefed the prime minister about the emerging scenario globally driven by the new variant, with an overview of the surge in cases in countries having high vaccination coverage and presence of the Omicron variant, it said.

He was also apprised of the technical brief and priority actions recommended by the WHO in the context of Omicron.

A snapshot of the status of Covid -19 and Omicron in the country, including states reporting a higher number of cases, districts reporting higher positivity, and higher number of clusters, was presented to the prime minister, the PMO said.

The details of the omicron cases reported in the country, including their travel history, vaccination status, and recovered status were also presented, it said.

He directed the officials to ensure that the health systems in the states, beginning from the district level, are strengthened to meet any challenge posed by the new variant.

It is important for states to ensure that the Oxygen supply equipment are installed and fully functional, Modi instructed the officials at the meeting.

He also directed the officials to work with the states on a regular basis and review the status of preparedness of various components of health infrastructure including training and capacity building of human resources, timely availability of ambulances, readiness of states to operationalise Covid facilities for institutional quarantining, and effective and supervised monitoring of those in home isolation.
