Bengaluru, May 6: More than a month after international flights have been barred, Karnataka government is preparing to quarantine all 10,823 of the state''s people poised to return home from overseas amid the Covid pandemic, an official said on Tuesday.

"The state has planned to quarantine all 10,823 passengers coming back to Karnataka. The quarantine guidelines framed as below would be applicable," said Health Commissioner Pankaj Kumar Pandey in a statement.

According to the Government of India, 10,823 Karnataka residents have been stranded abroad by April 30, comprising 4,408 tourists, 3,074 students, 2,784 migrants and professionals and 557 ship crew.

Out of the 10,823 people, the state government is expecting 6,100 to return early as the government has decided to allow Indians stuck abroad to return.

"All the passengers arriving at points of entry (airports and seaports) will be compulsorily screened for symptoms of Covid-19," said Pandey.

Point of entry screening will include self-reporting form verification, thermal screening, pulse oximeter reading, briefing with instructions, categorisation, stamping for some and downloading of Aarogya Setu, Quarantine Watch and Apthamitra apps.

Arriving passengers are also required to declare existing comorbidities such hypertension, diabetes, asthma or any lung disease, organ transplantations, cancer, tuberculosis and other ailments.

Passengers will be categorised into three groups: Category A (symptomatic on arrival), Category B (asymptomatic with co-morbidity or aged above 60 years) and Category C (rest of asymptomatic passengers).

Depending on the category into which the people fall, their quarantine place and time will be determined.

Category A arrivals will be subjected to institutional quarantine for a fortnight, Category B one week quarantine at a hotel or hostel, followed by another week at home, and Category C home quarantine for a fortnight.

Karnataka government is making elaborate arrangements and logistical means, deploying healthcare, police and several other departments into action to handle the huge influx of Kannadigas and state residents.

Pandey has issued a 21-page elaborate standard operating procedure (SOP) guidelines on how to face the international returnees.

May 12: Children suffering from non-respiratory disease symptoms like diarrhea and fever, or those with a history of exposure to the novel coronavirus, should be suspected of having COVID-19, a new study says.

According to the research, published in the journal Frontiers in Pediatrics, gastrointestinal symptoms first suffered by some children hints at potential infection with SARS-CoV-2 through the digestive tract.

"This case series is the first report to describe the clinical features of COVID-19 with non-respiratory symptoms as the first manifestation in children," the scientists from Tongji Hospital in China wrote in the study.

They explained that the gastrointestinal symptoms could be arising since the type of receptors in lung cells targeted by the virus can also be found in the intestines.

Most children are only mildly affected by COVID-19, and the few severe cases often have underlying health issues, the researchers said.

"It is easy to miss its diagnosis in the early stage, when a child has non-respiratory symptoms, or suffers from another illness," said study co-author Wenbin Li, who works at the Department of Pediatrics, Tongji Hospital.

"Based on our experience of dealing with COVID-19, in regions where this virus is epidemic, children suffering from digestive tract symptoms, especially with fever and/or a history of exposure to this disease, should be suspected of being infected with this virus," Li said.

In the study, the scientists described the clinical features of children admitted to hospital with non-respiratory symptoms, who were subsequently diagnosed with pneumonia and COVID-19.

"These children were seeking medical advice in the emergency department for unrelated problems, for example, one had a kidney stone, another a head trauma," Li said.

The study noted that all the children had pneumonia, which was confirmed by chest X-ray scan before or soon after admission.

These children were then confirmed to have COVID-19.

While their COVID-19 symptoms were initially mild or relatively hidden before their hospital admission, four out of the five cases had digestive tract symptoms as the first manifestation of this disease, the researchers said.

Li hopes that doctors will use the findings to quickly diagnose and isolate patients with similar symptoms, which may aid early treatment and reduce transmission.

According to the researchers, the children's gastrointestinal symptoms, which have also been recorded in adult patients, could be an additional route of infection.

"The gastrointestinal symptoms experienced by these children may be related to the distribution of receptors and the transmission pathway associated with COVID-19 infection in humans," Li explained.

Since the virus infects people via the ACE2 receptor, which can be found in certain cells in the lungs as well as the intestines, COVID-19 might infect patients not only through the respiratory tract in the form of air droplets, but also through the digestive tract by contact or fecal-oral transmission, the study noted.

While COVID-19 tests can occasionally produce false positive readings, Li said all the five children assessed in the study were infected with the disease.

However, he cautioned that more research is needed to confirm their findings.

"We report five cases of COVID-19 in children showing non-respiratory symptoms as the first manifestation after admission to hospital. The incidence and clinical features of similar cases needs further study in more patients," he said.

New Delhi, Jan 24: A nurse from Kerala employed at a hospital in Saudi Arabia has tested positive for the deadly novel coronavirus, Union minister of state for external affairs V Muraleedharan said on Thursday.

The minister confirmed that about 100 Indian nurses working in the Saudi Arabia hospital were tested following the threat of coronavirus and one of them was found infected by the deadly virus.

Taking to Twitter, MoS (MEA) Muraleedharan said, "About 100 Indian nurses mostly from Kerala working at Al-Hayat hospital have been tested and none except one nurse was found infected by Coronavirus. Affected nurse is being treated at Aseer National Hospital and is recovering well."
