Evacuation flight from UAE to Karnataka: Efforts of KNRI president Praveen Shetty pays off

New Delhi, May 3: The Indian Council of Medical Research (ICMR) has crossed over one million RT-PCR tests for COVID-19 on Saturday evening marking a big landmark, ICMR officials said.

"We have tested about 10,40000 tests till Saturday evening. In a few days, we have increased our testing capacity. ICMR has been doing more than 70,000 tests in the last two consecutive days," he said.

On Saturday, ICMR released that a total of 976363 samples have been tested till date. From May 1 till evening on Saturday, 1,37,346 tests were done.

The top three states which are doing vigorous testing includes--Maharashtra, Tamil Nadu and Rajasthan. As on date, these three states have conducted more than one lakh test respectively.

However, Andhra Pradesh, Uttar Pradesh, Karnataka and Delhi still need to ramp up their testing capacity.

ICMR has always emphasised that the confirmatory test for diagnosis of COVID-19 infection is RT-PCR test of the throat and/or nasal swab, which detects virus at an early stage. Recently, Dr GS Toteja, Additional Director General of ICMR had said that to contain coronavirus infection, RT-PCR tests must be continued vigorously as the principal diagnostic tests.

RT-PCR tests are now available in 310 government laboratories and 111 private set up across the country.

On Friday, the Centre informed that ICMR has ordered 21.35 lakh diagnostic kits. As on date, India has reported about 37,776 confirmed coronavirus cases and 1223 deaths.

The current physical distancing guidelines provided by the World Health Organisation (WHO) and by the US Centers for Disease Control and Prevention (CDC) may not be adequate to curb the coronavirus spread, according to a research which says the gas cloud from a cough or sneeze may help virus particles travel up to 8 metres. The research, published in the Journal of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.

Study author, MIT associate professor Lydia Bourouiba, warned that droplets of all sizes can travel 23 to 27 feet, or 7-8 metres, carrying the pathogen.

According to Bourouiba, the current guidelines are based on "arbitrary" assumptions of droplet size, "overly simplified", and "may limit the effectiveness of the proposed interventions" against the deadly pandemic.

 She explained that the old guidelines assume droplets to be one of two categories, small or large, taking short-range semi-ballistic trajectories when a person exhales, coughs, or sneezes.

However based on more recent discoveries, the MIT scientist said, sneezes and coughs are made of a puff cloud that carries ambient air, transporting within it clusters of droplets of a wide range of sizes.

Bourouiba warned that this puff cloud, with ambient air entrapped in it, can offer the droplets moisture and warmth that can prevent it from evaporation in the outer environment.

"The locally moist and warm atmosphere within the turbulent gas cloud allows the contained droplets to evade evaporation for much longer than occurs with isolated droplets," she said.

"Under these conditions, the lifetime of a droplet could be considerably extended by a factor of up to 1000, from a fraction of a second to minutes," the researcher explained in the study.

The MIT scientist, who has researched the dynamics of coughs and sneezes for years, added that these droplets settle along the trajectory of a cough or sneeze contaminating surfaces, with their residues staying suspended in the air for hours.

"Even when maximum containment policies were enforced, the rapid international spread of COVID-19 suggests that using arbitrary droplet size cutoffs may not accurately reflect what actually occurs with respiratory emissions, possibly contributing to the ineffectiveness of some procedures used to limit the spread of respiratory disease," Bourouiba wrote in the study

Bengaluru, Jan 2: Former chief ministers of Karnataka Siddaramaiah and H D Kumaraswamy on Thursday launched a scathing attack on Prime Minister Narendra Modi as he embarked on a two-day visit to the state attend events in Tumakuru and Bengaluru. In a series of tweets, the Congress and the JD(S) leaders took a dig at Modi for his alleged failure on various fronts.

"You did not visit Karnataka when it was devastated by floods, you did not visit Karnataka when our farmers cried for help, but all of a sudden, when you want to launch your political propaganda, you remember the innocent people of Karnataka. Wah Modi Wah!!" Siddaramaiah tweeted.

In another tweet, the Congress leader claimed Karnataka is starved of Central government funds as there were no adequate flood relief, no GST revenue loss compensation and there was a delay in the transfer of grant-in-aid.

He further said, "Before attempting to fool our people, let the people of Karnataka know when they will get their due share!" He also sought to know from Modi why the 25 MPs from Karnataka have 'turned off' their engines.

"With 25 MPs from BJP and a state government with BJP, people hoped for a double engine. Instead, all BJP representatives have turned off their engines and have become sycophants to play a tune to your idiosyncrasies. Why, are they scared of you?" Siddaramaiah said.

Seeking an explanation on various incomplete projects, the Congress leader said, "Mr Narendra Modi, people are fed up of your lies and double-edged sword comments. We want your answer today about long-standing questions on: Kalasa Banduri Yojana, Belagavi border issue, exams in Kannada, Tulu & Kodava in 8th schedule, the list goes on." Kumaraswamy too minced no words as he went on the offensive against the Centre.

In his tweets quoting newspaper reports, he said Karnataka's coffer has dried up, financial position is in doldrums and the revenue has plummeted.

"What's the reason (behind poor economic situation)? The poor economic policies of the Centre. After swallowing the GDP and development of the country, the wrong policies have affected the state too," alleged Kumaraswamy.

Quoting reports, Kumaraswamy said the Centre has denied the state's share of revenue.

"About 5.44 per cent of state's share is yet to come from the Centre. This is step-motherly attitude of the Centre towards the state," Kumaraswamy tweeted.
