BJP using Siddaganga seer for political gains by promising Bharat Ratna: Mate Mahadevi

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.

Dubai, May 18: An Indian working in a mining company in the UAE has become the latest expatriate to have lost his job for hate-filled social media posts targeting Islam and Muslims.

Brajkishore Gupta was fired without notice for calling Indian Muslims 'coronavirus spreaders' and hailing the Delhi violence as 'divine justice' in his Facebook posts.

Gupta, who is from Chapra, Bihar, was employed by Stevin Rock, a mining company headquartered in Ras Al Khaimah city.

"This isolated incident involving a junior employee was investigated and dealt with immediately resulting in the termination without notice of this person's employment with Stevin Rock," said the company's business development and exploration manager Jean-Francois Milian.

"Our company policy supports the direction of the UAE government in promoting tolerance and equality and strongly renouncing racism and discrimination and we have sent communications to all of our employees irrespective of their religious or ethnic background reminding them that any such behaviour is unacceptable and will lead to immediate dismissal," Milian was quoted as saying in the report.

Three Indians based in the UAE were either fired or suspended from their jobs for "Islamophobic" posts on social media early this month.

On April 20, India's ambassador to the UAE Pavan Kapoor had warned Indian expatriates against such behaviour.

"India and UAE share the value of non-discrimination on any grounds. Discrimination is against our moral fabric and the Rule of law. Indian nationals in the UAE should always remember this," he said in a tweet.

Last month, Sharjah-based businessman Sohan Roy had to apologise for "unintentionally hurting religious sentiments" through his poem, which alluded to a Muslim religious group.

In March, chef Trilok Singh was fired from a restaurant in Dubai for an online threat against a student in Delhi over her views on the Citizenship Amendment Act.
