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.

Gadag, Mar 28: At a time when the adminsitration is insisting on social diatancing due to COVID-19 outbreak, scores of people gathered in large numbers at an Agricultural Produce Market Committee (APMC) market in Gadag district to buy essential commodities.

Both men and women could be seen standing in large groups near the vendors to buy fruits and vegetables. Some of the customers were also heard bargaining with the sellers in the morning today.

A couple of days back, Prime Minister Narendra Modi emphasised that social distancing is the only way to counter the spread of COVID-19, saying the virus does not discriminate and it can infect anyone.

Interacting with the people of Varanasi through video conferencing, the Prime Minister had stated that some people, despite being empowered with knowledge, are not pay heed to warning which is unfortunate.

He said the 'Mahabharata' war was won in 18 days and the war against coronavirus will take 21 days and the aim is to win it.

According to the Union Health Ministry, there are 873 confirmed cases of COVID-19 in India.

Mangaluru, Ma 9: Three more persons from Bantwal taluk in Dakshina Kannada district tested positive for Covid-19 today. All three are members of a family.

The infection is reportedly linked to First Neuro Hospital of Mangaluru, which has emerged as a coronavirus hub in coastal Karnataka.

With this, the total number of coronavirus cases in the district mounted to 31 including six outsiders. Three of them have lost their lives. Currently there are 15 active cases in the district.

The newly identified coronavirus patients are a 30-year-old man and two elderly women aged 60 and 70 years.

They have contracted the infection from a 69-year-old man from Bantwal who was confirmed with COVID-19 infection on May 1. All the three members now infected belong to his family.

The man had got the infection from a woman identified as P-390. He happens to be a relative and neighbour of the deceased woman who belonged to Bantwal Kasaba village. Eight  members of his family were quarantined, of whom three tested positive today.
