Fourteen mentor institutes, including the AIIMS and NIMHANS, have been identified to mentor the medical colleges and expand the coronavirus testing capacity," he added.According to ICMR officials, a total of 1,86,906 samples have so far been tested across the country, of which 7,953 have been found positive for COVID-19."In the last five days, on an average, 15,747 samples were tested per day and 584 of those were found to be positive per day," an Indian Council of Medical Research (ICMR) official said at the press briefingA broad consensus has emerged that the national lockdown should be extended by at least two weeks after a meeting between Prime Minister Modi and state chief ministers on Saturday.Several chief ministers at the same time have pushed for resumption of some economic activities like in the farming sector in regions with no COVID-19 cases.The Centre in consultation with states is moving to restart economic activities in a graded manner in what is seen as a nuanced change in strategy from saving lives a month ago to saving lives as well as livelihoods now in the fight against the pandemic.It has sought inputs related to production, labour and logistics from clusters in five key sectors to ascertain expected output if they are made operational within a fortnight and procedural support required, official sources said.The five sectors are textiles, chemicals, electronics, steel and pharmaceutical, the sources said.States are likely to designate districts, towns and cities as red, orange and green zones depending upon the number of COVID-19 case as part of efforts to allow differentiated restoration of normalcy with conditions like uses of masks and social distancing in public.Union minister Nitin Gadkari said talks are underway with state governments to re-start highway construction projects where migrant labourers can be gainfully employed.In a video-conference with PTI, the road transport, highways and MSME minister said efforts are on for facilitating safe return of migrant labourers, an estimated 20 lakh of whom are in shelters pan-India."I had a meeting with road sector officials. Work can be re-started at projects with condition that adequate measures are taken for safeguard against coronavirus. We have to follow guidelines. At some places collectors have given permission, some not. We are doing a follow up along with the chief secretaries of the states," the minister said.Gadkari's comments come against the backdrop of a report by the World Bank that migrants face a stark choice between potentially starving in urban centres without work or long and potentially fatal journeys over hundreds of miles to their home districts.In the report titled “South Asia Economic Update: Impact of COVID-19”, the report at the same time said migrant workers returning home could become vectors carrying the coronavirus to unaffected states and villages and that preliminary findings indicated in India many out-migration areas are likely to have COVID-19 cases.The Centre has asked the state and union territories to take welfare measures for the migrant labourers living in camps in different parts of the country that include food, shelter, medicine, mobile and video call facilities.The Bihar government also reached out and provided relief to over 5 lakh distressed residents of the state stranded in Delhi and other parts of the country, a senior official said in Patna.The Karnataka government said it is studying in-depth the consequences of possible relaxation of lockdown norms after April 14 and plans to come out with a clear roadmap in a day or two, according to Medical Education Minister Sudhakar K .Kerala, which was the first state in the country to report a coronavirus infection in late January, has prepared a time table for coming out of the lockdown and there would be district-specific strategies to tackle the situation while the number of cases are on the decline.Ramping up efforts to "stamp out" coronavirus cases in the state, Kerala Finance Minister Thomas Isaac told PTI that an exit strategy is being prepared and restrictions are being relaxed in certain segments, including agriculture.
