Congress suffers blow in Devadurga as BJP candidate Shivanagowda Naik wins

Bengaluru, Apr 6: The Covid-19 Task Force aims to conduct 80,000 throat swab and blood tests over the next three weeks here.

According to Task Force Nodal Officer C N Manjunath an order for one lakh anti-body test kits has been placed, and was expected to arrive on April 12.

"From January 20 to March 23, more than 1.2 lakh people arrived at international airports from abroad. Of these, we have kept 37,358 under observation. The Health officials and personnel in fever clinics and hospitals are being trained to conduct the tests. There is no necessity to obtain a clearance to test people with suspected infection. Only laboratories need to get permission to test their blood and throat swab samples."

Bhatkal, May 9: A day after 12 covid-19 positive cases reported from Bhatkal, seven more tested positive for the coronavirus in the town today. 

The new patients are: a six-month-old baby, a two-and-a half-year-old child, two girls aged 17 and 23, a 50-year-old woman and two elderly men aged 65 and 68 years.

The source of all these cases is said to be the First Neuro hospital located at Padil in Mangaluru where a covid-19 patient from Bantwal had undergone treatment a month ago. Around 20 days ago an 18-year-old girl from Bhatkal, who had been to the same hospital was tested positive for the covid-19. 

After the confirmation of 12 covid-19 positive cases yesterday, the throat swab of 60 people, who were in contact with them were sent for testing. Among them seven people – six relatives and a friend – were tested positive today.

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.
