Smriti Irani a low-level actress; deserves jail, not HRD ministry: Mysuru professor

New Delhi, Apr 12: Ramping up efforts to "stamp out" coronavirus cases in the state, Kerala Finance Minister Thomas Isaac has said that not only lockdown but intense testing of people and tracing of their contacts are also equally important in the fight against the outbreak.

Kerala, which was the first state in the country to report a coronavirus infection in late January, has also 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.

In efforts to curb spreading of coronavirus infections, the country is under a 21-day lockdown till April 14 and many states have sought an extension amid rising number of cases. Kerala has proposed extending the lockdown and gradual phasing out after proper assessment.

"Lockdown should go on till we stamp out entire infections. Now, it is not enough to have lockdown. Equally important is that we should have intense testing, tracing and isolating (of people with coronavirus infections)," he said in a telephonic interview.

The government is closely monitoring the situation and there would be region-specific or district-specific strategies in place to tackle the outbreak, he said.

Against the backdrop of the lockdown that has also disrupted economic activities, Isaac said an exit strategy is being prepared and restrictions are being relaxed in certain segments, including agriculture.

"The number of patients is coming down (in the state). We hope that in the coming days, the decline will be much more faster," he said during the interview late Friday.

On Saturday, the Kerala government said there were a total of 373 confirmed cases of coronavirus infections and 228 patients were under treatment in various hospitals in the state.

Keeping the trend in the last few days, the number of people under observation has come down to 1,23,490. So far, 14,613 samples from people with symptoms were sent for testing and the results of 12,818 samples have come negative, the government said in a statement on Saturday.

Indicating that there would be a calibrated exit from the lockdown, Isaac said the withdrawal would depend on three main factors, including the count of cases and the percentage of people who are under observation.

While emphasising that people must also be fed during the lockdown period, Isaac also said a time table is being prepared by the state to come out of the lockdown.

Even as strict measures are being implemented to deal with the current situation, the state is also preparing for a possible third wave of coronavirus cases.

Three students, who had returned from the Chinese city of Wuhan, were tested positive. They were also the first such cases, to be reported in January-February period, and have recovered. Wuhan was the epicentre of coronavirus infections before it spread to other countries.

Later, there was a second wave of infections in Kerala.

According to the minister, the possibility of a third wave has also been considered for the exit strategy.

"A lot of Malayalees are expected to come back from outside the state. We will welcome them... before that, we want to stamp out all Covid cases in Kerala. Flatten the curve completely so that when these people from outside, they will be quarantined, they will be tested and only then they will be able to integrate with the rest of the community," he said.

The Kerala government's measures, including extensive testing and efforts to trace people who came in contact with coronavirus-infected persons, have helped in curbing spreading of infections.

The state's public healthcare system has also been appreciated in various quarters.

"People are health conscious. There is a demand for quality healthcare services and the response to this demand has been strengthening of the public healthcare system. We have a robust public healthcare system," the minister emphasised.

On April 9, Isaac tweeted about low level of coronavirus spreading in the state.

"International norm for Covid spread is 2.6 per 1 Covid patient. Total number of primary Covid infected who arrived in Kerala from abroad is 254. The secondary spread has been limited to 91. The international mortality rate is 5.75. With just 2 deaths, rate in Kerala is 0.58," he had tweeted.

Death toll due to the coronavirus increased to 273 and the number of cases to 8,356 in the country on Sunday.

University of Oxford researchers have claimed that a cheap and widely available drug called dexamethasone can help save the lives of patients who are seriously ill with coronavirus.

Scientists working on the Recovery Trial found the drug could help patients on ventilators and oxygen, but had no effect on those who did not need help breathing.

“Based on these results, one death would be prevented by treatment of around eight ventilated patients or around 25 patients requiring oxygen alone,” researchers said in a statement.

Matt Hancock, the health secretary, tweeted: “This global first exemplifies the power of science.”

“I’m absolutely delighted that today we can announce the first successful clinical trial for a treatment for Covid-19,” Mr Hancock said.

Recovery Trial experts said a randomised group of 2,104 patients was given 6mg of dexamethasone per day for 10 days, while another group of 4,321 were given normal treatment.

Dexamethasone reduced deaths by one-fifth in patients on oxygen feeds and by one-third in those who needed a ventilator to breathe, preliminary results showed.

Mr Hancock added: “This is a huge step forward and it’s because we’ve backed the science.”

Martin Landray, professor of medicine and epidemiology at the Nuffield Department of Population Health, University of Oxford, and one of the trial’s chief investigators, said in a statement: “These preliminary results from the Recovery Trial are very clear – dexamethasone reduces the risk of death among patients with severe respiratory complications.

“Covid-19 is a global disease – it is fantastic that the first treatment demonstrated to reduce mortality is one that is instantly available and affordable worldwide.”

Bengaluru, Apr 12: The Karnataka government is studying in-depth the consequences of the possible relaxation of lockdown norms after April 14 and plans to come out with a clear roadmap in a day or two, a key Minister said on Sunday.

Medical Education Minister K Sudhakar, who is in charge of all matters related to COVID-19, told PTI that the pros and cons of any decision that the Government intends to take is being looked at in detail.

"We are trying to understand how the situation would be of any action that we intend to take. We need to foresee the repercussions or results of our action. That we have to keep it in mind and make a decision. After-effects of the decisions we intend to take, that is more important, he said. You will have clarity (on the possible relaxation of lockdown norms) in a day or two. For everything (government decisions) we will give the reasoning for what action we would like to take; with the reasoning, we will give a decision," the Minister added.

Government sources said some relaxation in liquor sales, stopped during the lock-down period, is likely after the ongoing 21-day national clampdown ends on April 14. Twelve of the state's 30 districts remain free from the COVID-19 pandemic. Till Saturday, Karnataka reported 215 COVID-19 positive cases, including six deaths and 39 discharges.
