New Delhi, Jul 3: The aviation regulator DGCA said on Friday it was extending the suspension of scheduled international passenger flights in the country till July 31 but added that some international scheduled services on selected routes may be permitted on a case to case basis.

Scheduled international passenger flights were suspended in India on March 23 due to the coronavirus pandemic.

Modifying its June 26 circular that stated that scheduled international passenger flights will remain suspended till July 15, 2020, the regulator stated on Friday it has decided to extend the deadline to July 31, 2020.

However, international scheduled flights may be allowed on selected routes by the competent authority on a case to case basis,” said the circular by the Directorate General of Civil Aviation (DGCA).

Air India and other private domestic airlines have been operating unscheduled international repatriation flights under the Vande Bharat Mission, which was started on May 6 by the Central government.

India resumed scheduled domestic passenger flights on May 25, after a gap of two months.

Bengaluru, Jul 7: There seems no impact of Covid-19 on kharif crop sowing in Karnataka with the current year actually being ahead of previous years, according to an official here on Monday.

"In agriculture, as far as sowing is concerned, there is no impact of COVID-19," Agriculture Commissioner Brijesh Kumar Dikshit told IANS. One of the reasons, according to Dikshit, is that people in rural areas are aware, but not scared of the pandemic.

"In rural India, coronavirus is there. People are aware, not scared. They are taking precautions, but don't have any phobia," he said.

Another reason was that by June the number of infections in Karnataka was not as high as other states, when a lot of sowing was done, he said.

By the end of June, Karnataka saw 15,242 Covid-19 cases. Of that, 7,074 were active.

The sowing is ahead of previous year as it's mostly dependent on weather. "It's ahead of previous years. Agriculture is directed by weather and rains had been slightly earlier this year," he said.

According to Karnataka State Natural Disaster Monitoring Centre, at 185 mm the state received 14 mm less rain in June against the normal 199 mm. "It's like a normal year, or slightly a good year," he said.

Some crops will be sown in the last fortnight of July and few more will extend up to August 15. "The last two weeks will be critical and on July 31 we should be able to tell whether we are short or ahead," he said.

According to preliminary indications, the Commissioner said the area under agriculture is increasing this year, which could also be because that labourers might have come back.

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.
