Potholes on roads? Inform these officials and complain to representatives

Udupi, Feb 23: Karnataka's minister for Tourism and Culture CT Ravi on Sunday said that India is losing money as because people travel abroad to visit casinos.

Arguing that casinos are being used by countries to promote tourism, he took to Twitter to highlight the issue, saying, "During my interaction with FKCCI, I had mentioned that many countries have promoted Tourism through Casinos. Isn't it a fact that lakhs of Indians go abroad to play in Casinos? Can anyone stop them? At the moment, there is no proposal before Our Govt to set up Casinos here,' he tweeted in the morning.

He also urged the Central government to stop people from visiting abroad.

Yesterday, the minister had stated that he has no intention of developing "casino tourism" in the state.

"I only expressed my opinion on how other countries have promoted tourism, during a discussion. Casino tourism is one such thing, I have no intention of developing it here," Ravi had told media when asked to comment on Karnataka government's proposal of casinos in Coastal Karnataka.

"What I meant was many Indians go and spend there, our money should be spent here itself," he had said.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Apr 17: Forty-four new cases of coronavirus have been reported in the State till now, said Karnataka's Health Department on Friday.

"44 new COVID-19 cases reported in the State from 5 pm Thursday to 5 pm on Friday. The total number of positive cases in the State is 359 including 13 deaths and 88 discharges," said the Health Department.

Meanwhile, a meeting was convened to review the situation on the rising cases of coronavirus in the State. According to Karnataka Chief Minister's Office (CMO), the meeting was attended by Chief Minister BS Yediyurappa, Home Minister Basavaraja Bommai, Health Minister B Sriramulu, and Deputy Chief Minister Ashwath Narayan.

The CMO said: "Earlier we used to do 500 tests per day. Now we are doing 2,000 tests. The suggestion was made to take care of the people who are in the ICU to prevent death. It was suggested and planned to work out a protocol for the treatment of COVID-19 patients all over the state."

The meeting also stressed the need for plasma treatment. Experts opined that people having influenza-like symptoms like fever, cold, breathlessness, etc., need to get tested for COVID 19.

The CMO said: "Officers were directed to conduct tests of the people with influenza-like symptoms in the districts where nil cases have been reported. ICMR has issued circular to set up two labs in each district and one lab in each medical college. In this direction, efforts are being made to set up 10 more labs in the State by the end of April."

"It was also decided to be prepared for treating an increased number of patients after relaxing in lockdown. It was also decided to issue guidelines to companies that would start working after relaxing lockdown. It was also decided to appeal to people to download Arogya Setu App. We will meet on April 21 again to decide further course of action," added the CMO.
