Tulu comedy king Naveen D Padil to enter Bigg Boss house

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.

Bengaluru, Feb 4: A 33-year old woman techie allegedly stabbed her mother to death and made a murderous assault on her younger brother before fleeing their home here, police said on Tuesday.

According to police, the woman fatally stabbed her mother using a knife and attacked the brother early on Monday.

The injured brother has been hospitalised here.

A search was on for the techie and the motive for her action under investigation, police said.

The woman, employed as a software engineer with a company here, earlier had told her mother and 30-year old brother that she has been transferred to Hyderabad and she may have to relocate.

The brother told police that in the early morning on Monday he saw his sister searching something desperately and offered to assist, which she refused.

However, minutes later she made a murderous assault on him, he told police, adding when he screamed for help and called his mother, his sister said she has killed their mother.

She stabbed him and attacked with an iron rod before fleeing, her brother told police.

The body of the mother was found in another room in the house.

"We are still investigating the matter. We are not clear about the motive behind the murder," a police officer told media adding the woman was yet to be arrested.

Istanbul: Mosques in Turkey reopened on Friday for mass prayers after more than two months as the government further eased strict restrictions to stop the spread of the new coronavirus.

Turkey has been shifting since May to a "new normal" by easing lockdown measures and opening shopping malls, barbershops and hair salons.

President Recep Tayyip Erdogan has said many other sites -- restaurants and cafes as well as libraries, parks and beaches -- will reopen from Monday.

Hundreds of worshippers wearing protective masks performed mass prayers outside Istanbul's historic Blue Mosque for the first time since mosques were shut down in March.

In the Ottoman-era Fatih mosque, worshippers prayed both inside and outside, with the municipality handing out disinfectants and disposable carpets.

"I have waited a lot for this, I have prayed a lot. I can say it's like a new birth, thanks to God, he has brought us back here," he said.

Another worshipper, Asum Tekif, 50, said: "It has a been a long time... we missed the mosques."

Turkey, a country of 83 million, has so far recorded 4,489 coronavirus-related deaths and 162,120 confirmed cases.

Prayers in Hagia Sophia

Muslim clerics on Friday recited prayers in the Hagia Sophia, the world famous Istanbul landmark which is now a museum after serving as a church and a mosque.

The prayers were held to celebrate the anniversary of the conquest of Constantinople, today's Istanbul, by the Ottomans in 1453.

"It is very important to commemorate the 567th anniversary of the conquest ... through prayers in the Hagia Sophia," said President Recep Tayyip Erdogan, who attended the ceremony via videoconference.

The stunning edifice was first built as a church in the sixth century under the Byzantine Empire as the centrepiece of its capital Constantinople.

After the Ottoman conquest, it was converted into a mosque before being turned into a museum during the rule of Mustafa Kemal Ataturk, the founder of modern Turkey, in the 1930s.

But there have been hints about reconverting the Hagia Sophia into a mosque. Last year, Erdogan himself mooted the possibility of turning Hagia Sofia museum into a mosque.

Such calls have sparked anger among Christians and raised tensions with neighbouring Greece.

In 2015, a Muslim cleric recited the Koran in the Hagia Sophia for the first time in 85 years to mark the opening of an exhibition.

After Friday prayers at the Blue Mosque, a small group of Muslim worshippers shouted: "Let the chains break and let the Hagia Sophia open".

The group was later dispersed by the police who stopped them from protesting near Hagia Sophia that sits immediately opposite the Blue Mosque.
