Planning to elope and marry in a temple? Now it's impossible in Mangaluru!

Bengaluru, Jul 4: Karnataka Congress leader Dinesh Gundu Rao said on Saturday that he and his family would get tested for COVID-19 after one of his security persons tested positive for the infection.

Rao's family will also be in-home quarantine for the stipulated time.

"One of my police security person has tested positive for COVID yesterday. My family members and I are getting tested now and will be in-home quarantine for the stipulated time period. None of us are showing any symptoms," he said.

The total number of cases in Karnataka stands at 19,710. Out of them, 8,805 have recovered and 293 patients have lost their lives, according to the Union Health Ministry.

Across the country, the total number of cases stands at 6,48,315. As many as 3,94,227 patients have recovered so far and 18,655 have lost their lives due to the virus.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Kasaragod, Apr 19: Kasaragod, Kerala's COVID-19 hotspot, is the only district in the southern state lacking adequate health infrastructure.

In spite of treating the highest number of COVID-19 patients in the state with meagre infrastructural facilities and even without the support of a medical college in the north Kerala district, no deaths have been reported due to coronavirus.

The state health department views the performance of M Kunhiraman and his team, consisting of Janardhana Naik and Krishna Naik, at the General hospital in Kasaragod as a success story.

"Not only did they control the situation quickly with minimum infrastructure, they also started turning out a large number of negative cases within a few weeks and creditably ensured zero mortality.

This can be showcased as a best global model," Chairman of the Information Education and Communication (IEC) Committee and Project Director Kerala State Aids Control Society, R Ramesh said.

Recalling the ordeal, Janardhana Naik said his first major challenge was the physical examination of a patient with suspected COVID-19.

"Even with the PPE kit, nobody knew how effective they were and it took a whole 30 minutes to wear them properly.

But as time passed, we got accustomed to it," he said.

The traditional method of dealing with a patient involved knowing his or her history, observation and physical examination.

For hundreds of years, the hands-on body approach has been the soul of the doctor-patient relationship -- taking the pulse, tapping on and listening to the chest, feeling lumps.

With the onset of COVID-19 all that has changed.

"In fact, the whole exercise was fraught with grave risks because everything connected with COVID-19 was new.

Doctors have to keep a distance even though the physical examination wearing a Personal Protective Equipment (PPE) is difficult.

Sounds from the body are inaudible, vision is blurred through the smog-covered goggles and a stethoscope seldom has any use," Janardhana Naik said.

It was from March 15 that the hospital started receiving COVID-19 patients, primarily from Dubai.

By the time the first person came, the hospital was ready for him.

Soon, patient numbers began to swell and in a couple of weeks they reached about 91.

From then on, it was teamwork.

Committees were formed for each and every task, including the help desk, IT, treatment, medical board, training, food, waste disposal and data maintenance.

Initially, patients had many misgivings about the hospital.

"Some were disillusioned and even aggressive. Some were not happy with the facilities the hospital had to offer.

But gradually through good treatment and counselling by a psychiatrist, who visited the hospital on alternate days, the confidence and mood of the patients changed and they became friendly with the staff," Naik elaborated.

Counselling was also given to the concerned family members of the patients.

Besides treatment, the medical staff had to spend a considerable amount of time clearing the doubts of patients.

When they got discharged some patients insisted on seeing the faces of the medical staff, who till then were anonymous entities covered from head to toe.

Some even wanted to take selfies with them.

However, the medical team politely turned down their requests and preferred to remain hidden in their work attires.

The mood of the patients also rubbed off on the doctors and hospital staff.

All the physicians and hospital staff are now more confident of dealing with contagious diseases after treating COVID-19 patients.

"Our previous experience of treating H1N1, Chikungunya and Dengue cases helped us a lot.

Words of encouragement from the Health Minister K K Shailaja, Health Principal Secretary Dr Rajan N Khobragade and Health Services Director Dr Sarita R L gave us the impetus to build up confidence.

Moreover, the field health workers did a wonderful job in containing the viral spread," Naik added.

As the number of coronavirus cases rose, the state government on April 5 deputed a 26-member medical team from Thiruvananthapuram to set up a COVID-19 hospital in the district.

They turned a block of the under construction Government Medical College as a hospital-like facility, setting up a 200 bed facility to treat coronavirus patients.
