Kerala Chief MinisterPinarayi Vijayan on Sunday alleged that efforts were being made to undermine the achievements of the state government in its fight against Covid-19 and said he was "ignoring" them as it was not the time for controversies.The Opposition Congress has been raising allegations that a US-based company had been entrusted with the task of collecting data regarding the virus-infected patients in the state, in violation of fundamental rights."Many developed nations are in awe of the achievements of Kerala in its fight against Covid-19 pandemic. This is the speciality of Kerala model," Vijayan said.Referring to the data collection charge levelled by the opposition parties, Vijayan said some were engaged in slandering the state government."Those who think that the government should not have a reputation for effectively handling the coronavirus outbreak are engaged in slandering the state government.It has happened before, it's happening now also. This is not the time to go behind controversies. People are watching and they will evaluate," Vijayan said in his weekly interactive programme 'Naam munnott'.He said he had decided to ignore such controversies.The ward-level committees, set up by the government for the anti-coronavirus fight, was collecting information of those under home isolation, elderly persons and those at the risk of the disease using a questionnaire in this regard and upload it on the server of the private agency.The Congress has alleged that the data, collected through the government machinery, was being uploaded not on the government server but on that of the foreign company.
