As covid cases continue to mount, Karnataka govt changes travel rules

Washington, Jun 30: Researchers in China have discovered a new type of swine flu that is capable of triggering a pandemic, according to a study published Monday in the US science journal PNAS.

Named G4, it is genetically descended from the H1N1 strain that caused a pandemic in 2009.

It possesses "all the essential hallmarks of being highly adapted to infect humans," say the authors, scientists at Chinese universities and China's Center for Disease Control and Prevention.

The researchers then carried out various experiments including on ferrets, which are widely used in flu studies because they experience similar symptoms to humans -- principally fever, coughing and sneezing. 

G4 was observed to be highly infectious, replicating in human cells and causing more serious symptoms in ferrets than other viruses.

Tests also showed that any immunity humans gain from exposure to seasonal flu does not provide protection from G4.

According to blood tests which showed up antibodies created by exposure to the virus, 10.4 percent of swine workers had already been infected.

The tests showed that as many as 4.4 percent of the general population also appeared to have been exposed.

The virus has therefore already passed from animals to humans but there is no evidence yet that it can be passed from human to human -- the scientists' main worry.

"It is of concern that human infection of G4 virus will further human adaptation and increase the risk of a human pandemic," the researchers wrote.

The authors called for urgent measures to monitor people working with pigs.

"The work comes as a salutary reminder that we are constantly at risk of new emergence of zoonotic pathogens and that farmed animals, with which humans have greater contact than with wildlife, may act as the source for important pandemic viruses," said James Wood, head of the department of veterinary medicine at Cambridge University.

A zoonotic infection is caused by a pathogen that has jumped from a non-human animal into a human.

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.

Bengaluru, jul 6: With coronavirus cases surging and hospitals saturated with patients, the Karnataka government is setting up intensive care units (ICUs) at COVID Care Centres (CCC) in the state for severe cases needing oxygen, Deputy Chief Minister C N Ashwath Narayan said on Sunday.

Covid Care Centres are usually meant for patients who are asymptomatic or have mild symptoms.

"Initially, 10 ICUs will be set up at every CCC in Bengaluru and in other cities and towns across the state subsequently," Narayan said in a statement in Bengaluru.

The state government has set up CCCs at the GKVK campus, the Haj Bhavan and the Art of Living Foundation campus in the city so far. The government has also set up a more than 10,000 bed CCC facility in BIEC, on Tumkur road, on the outskirts of the city.

"About 100 ICUs will be set up soon at the new CCCs opened at the Bangalore International Exhibition Centre (BIEC), Ayurveda College, and Koramangala Indoor Stadium," said Narayan.

The sprawling BEIC in the city's northwest will soon have 10,100 beds for treating Covid patients and asymptomatic cases from state-run hospitals.

The state government has also relieved all Health Department employees from administrative and non-medical duties to depute them at the CCCs.

On complaints about the poor quality of food served to Covid patients and the medical staff, Narayan warned the vendors of cancelling their contracts if they did not supply good quality food as per the guidelines.

The minister also directed the Health Department to ensure adequate supply of drugs and medical equipment to all CCCs and state-run hospitals for treating Covid patients.

With a record 1,925 new cases reported on Sunday, the state's tally touched 23,474, including 13,251 active after 9,847 were discharged (including 603 on Sunday), while 372 succumbed to the infection since March 9, with 37 more deaths on Sunday.

Of the total cases across the state, Bengaluru accounted for 1,235, taking its tally to 9,580, including 8,167 while 145 died so far.
