New Delhi, Sep 19 (PTI) Expressing concern over COVID-19 fatality rates in some states being higher than the national average, the Cabinet secretary on Saturday urged 12 states and UTs to analyse mortalities district and hospital-wise to identify critical areas of intervention. At a high-level review meet, he also exhorted them to ensure optimal utilisation of RT-PCR testing capacity, while underlining the need for ensuring that no symptomatic negative case tested in rapid antigen examination is missed, and all such cases mandatorily undergo RT-PCR test, the Union Health Ministry said. During the meeting chaired by the cabinet secretary, the minister of commerce and industry addressed these states and UTs and reviewed the oxygen availability there. The 12 states and Union Territories that participated in the virtual meet included Maharashtra, Karnataka, Andhra Pradesh, Uttar Pradesh, Tamil Nadu, Odisha, Chandigarh, Telangana, Kerala, Delhi, Punjab and West Bengal, the health ministry said. "About 80 per cent of the COVID-19 caseload in the country is concentrated in these states and UTs," it said. "The Minister of Commerce and Industry specifically requested them to focus on analysing district-level and health facility-level status and effectively plan and manage logistical issues related to oxygen availability," the health ministry said. He also urged the states and Union Territories to share their best practices which in turn can be emulated by others in the country. The Union Health Secretary, Member (Health) in NITI Aayog, Secretary in the Department of Promotion of Industry and Internal Trade, senior officials of the Health Ministry, Home Ministry and chief secretaries of the 12 states and Union Territories participated in the review meeting. "The cabinet secretary, while complementing the states for significantly ramping up testing, expressed concern that the case fatality rates of several states are still higher than the national average. He urged the states to analyse mortalities district and hospital-wise for identification of critical areas of intervention," the statement said. The Union Health Secretary also presented a detailed status note of COVID-19 in all these states with particular focus on the number of tests being conducted in each of them, their positivity rate and average daily fatality rate, availability of health infrastructure and their district-wise oxygen availability.
