Budget shocker: Modi govt proposes tax on non-taxpaying NRIs

Bengaluru, Apr 29: As many as 11 more people have tested positive for the coronavirus in the last 24 hours in Karnataka, said the State's Health Department on Wednesday.

According to an official statement, 11 new COVID-19 positive cases were reported from 5 pm on April 28 to 5 pm on April 29.

"With this, the total number of positive coronavirus cases in the state has mounted to 534, of which 20 deaths have been reported and 215 people have recovered," added the statement.

Of 20 coronavirus patients who died, one death was due to the non-COVID cause, the statement further said.

Shivamogga, May 12: Roopa Praveen Rao, an expectant mother and a nurse at a hospital in Shivamogga's Karnataka, has chosen to continue to serve the patients amid the ongoing COVID-19 crisis.

Rao who hails from Gajanuru village is nine months pregnant and works at Jayachamarajendra Government Hospital as a nurse.

She travels every day to Thirthahalli taluk to attend to the patients at the hospital.

"The taluk hospital is surrounded by many villages, people need our service. My seniors had asked me to take leave but I want to serve people. I work six hours a day," she told news agency.

She added that Chief Minister B S Yediyurappa too called her up and appreciated her dedication and suggested that she should take rest.

Rao is one of the many frontline COVID-19 warriors who have been risking their lives to ensure that everyone stays safe as the country fights the coronavirus.

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.
