3 cops suspended for ‘royal treatment’ for accused in Bhaskar Shetty murder case

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Benagluru, Feb 27: The sudden hike in bus fares by the state-run transport corporation has triggered a public outrage and protests by the opposition Congress and the Janata Dal-Secular (JD-S) in Karnataka.

Terming the hike as anti-people and inflationary, the Congress urged the ruling BJP to withdraw it forthwith and spare the commuters from the additional burden.

"KSRTC and its affiliates should not further burden the people when the cost of living has gone up and its bus service is used by the majority in the absence of trains in many regions of the state," said Ravi Gowda of the Congress.

In a surprise announcement on Tuesday night, the Karnataka State Road Transport Corporation (KSRTC) and its two affiliates -- North Eastern Karnataka Road Transport Corporation (NEKSRTC )and North Western Karnataka Road Transport Corporation (NWKSRTC) -- increased bus fares by 12% with effect from Wednesday, drawing the ire of commuters and opposition parties alike.

Condemning the fare hike, JD(S) leader and former Chief Minister H D Kumaraswamy urged the KSRTC to roll back the revised fares and give relief to the common man reeling under price rise due to CGST, SGST and food inflation.

"The BJP government has deliberately increased the bus fare ahead of the state budget for 2020-21 fiscal on March 2, catching people unawares. Though student passes have been spared from the hike, regular passengers are forced to pay Rs 5-32 more instead of getting better efficiency, management and productivity," Kumaraswamy said in a statement in Bengaluru.

It's an additional burden on us, said Bengaluru resident K. Venkatesh, while adding,

"The 12 percent hike in bus fares by the KSRTC and its north-east and north-west affiliates from Wednesday will hit passengers hard and make commuting costly.”

"The fare hike will negate the state government's efforts to encourage public transport service and force passengers to travel on the train, which is cheaper, faster and safer," asserted Venugopal Gupta, a cloth merchant in the city.

Justifying the hike, KSRTC Managing Director Shivayogi Kalasad told media that the hike was inevitable due to the steady increase in diesel price, dearness allowance in staff salary and overall cost of operations.

"Since the last fare revision came in May 2014, the operational cost has gone up substantially due to Rs 11.27 per litre hike in diesel price, increase in DA to employees and repairing, maintenance and fleet management costs," Kalasad said.

The financial burden due to fuel price hike is Rs 261 crore, DA Rs 341 crore and operational cost Rs 601 crore per annum for KSRTC alone, he said.

"For the benefit of rural passengers, fares have been reduced to Rs 5 from Rs 7 for the first 3 km. There is no increase in fares for the first 12 km and up to first 6 km in express service," Kalasad added.

Bengaluru, Mar 19: Medical Education Minister Dr Sudhakar on Wednesday said that the government is increasing the number of labs for COVID-19.

"For the last two months, screening has been done at airports. Quarantine is also being done. The situation was reviewed by the state cabinet. All passengers from abroad will be home quarantined or they can stay at government facilities or budget hotels or resorts or private hospitals," Sudhakar said in the Assembly.

"We have issued many advisories. Until 31st March, pubs, and hotels, religious events, should not have an assembly of more than 100 persons. Two bulletins will be issued twice a day. All those who arrive from abroad will be stamped that they have arrived from abroad. Covid-19 is growing at a phenomenal pace. We need not panic but we need to be cautious," he said.

Sudhakar continued: "There are 54 labs in the country. Karnataka has five labs, the most among all states. We are increasing the number of labs. In our country, we have tested less than 10 per cent. In Karnataka, we should conduct test on more people."

The minister said the government will devise a way to be able to track down all those home quarantined through their mobile phones.

"Karnataka stands fourth after Maharashtra, Kerala and Uttar Pradesh. We are in the second stage. The next 2-3 weeks are detrimental. This is a pandemic situation. People have to also take responsibility. Social distancing is the real solution and key to eradicating this COVID-19. In the larger interest of the health of the state, we have to take drastic measures," he said.

"We are now in the 2nd stage. The next 3 weeks are very important. If we take care, the state can escape what's happening worldwide," he said.

Congress MLA UT Khader demanded action against those people who do not follow rules.

"Only shutting airports will not help. What about domestic passengers? Coronavirus must come under Ayushman Bharat. Keep isolated patients away from normal people in the ICU in government hospitals. Take action against those who do not follow the rules," he said.

Congress MLA Dr Yathindras said that screening is not enough and travelers need to be lab tested.

A total of 151 positive cases of coronavirus have been reported in India so far, the Union Ministry of Health and Family Welfare said on Wednesday.

Thirteen positive cases of COVID-19 have been reported in Karnataka till today.
