Kerala: India's first Islamic bank gets RBI approval

Udupi, June 30: A girl who appeared for SSLC exams in three subjects tested positive for COVID-19 in Kundapur taluk of Udupi district today.

Sheshashayana Karinja, Deputy Director of Public Instruction (DDPI) said that the 15-year-old girl had a headache and her parents took her for testing and she had tested positive for COVID-19.

She will appear for the remaining three subjects during the supplementary exams in August.

The room where the girl appeared for the exam had been sanitised. But exams would not be held in that room. All precautions have been taken in that exam centre in Kundapur taluk, Mr. Karinja said.

The other 19 students will be allowed to write their exams as there was a distance of one metre between them and there was no contact between the students during the exams, Mr. Karinja added.

It is learned that a couple of months ago, a Mumbai returnee who recovered from COVID-19 had visited the girl’s house. However, it is not clear that she got an infection from the Mumbai returnee.

It could be recalled here that a student from Hejamadi in Udupi district who was preparing for the Science exam had tested positive two days back and she is currently being treated at a hospital.

Bengaluru, Jul 15: Karnataka Congress Chief D K Shivakumar on Wednesday urged the Ministers in the state to visit Covid-19 designated hospitals and instil confidence among patients, doctors and medical staff there.

Noting that doctors, nurses and others were doing a great job, Shivakumar said the government has to stand with them and instil confidence in them. Speaking to reporters after visiting Victoria hospital, a major dedicated Covid hospital in the city, he said, "All the Ministers have to go to hospitals and instil confidence in the staff, patients.... they have to remove fear and tell them we will have to live with this (virus), and cannot escape from it."

Shivakumar said he believes that by instilling confidence most part of the diseases can be cured. He lauded doctors, paramedical and other staff working at the Hospital for the sake of patients, putting their own life at risk and appreciated facilities provided there.

During the visit, the state Congress President interacted with patients undergoing treatment for Covid-19, also medical staff and doctors. He said at Victoria hospital patients were allowed to use mobile phones, so that they can speak to family members, which has to an extent instilled confidence among them, and the same has to be replicated across the state.

Not wishing to comment on complaints about the quality of facility and PPE kits provided at the hospital, also alleged misappropriation on part of the government in the purchase of equipment for Covid treatment, Shivakumar said, "....let's see that at Vidhana Soudha (seat of state's legislature)." He said, "this is not the time to talk about corruption and other things, this is not the time for it....instilling confidence among patients, doctors and paramedical staff is important now."

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
