Rains recede, woes continue

Jan 2: A year after 12,000 acres of forests in Bandipur went up in smoke, the Karnataka Forest Department is gearing up for the summer even as the Forest Survey of India (FSI) has cautioned that 22.78 lakh acres (9,222 sq km) or about 20% of the green cover spread across three districts in the central part of the state is fire-prone.

The FSI studied forest fire incidents across the country between 2004-05 and 2017 before coming up with state-specific inputs.

According to the 13-year observation, Karnataka has 7,352 “fire points” or areas measuring 5 km X 5 km with frequent fire incidents.

Though the number is lower compared to states like Maharashtra, Madhya Pradesh and Odisha with over 20,000 points, the sheer spread of the fire-prone area itself is a challenge for the Karnataka Forest Department.

According to data, about three lakh acres (1,199.9 sq km) of forest area is very highly fire prone with 26 to 52 fire incidents in 13 years. This is followed by 7.6 lakh acres (3,067 sq km) of “highly fire prone” areas with an average of one to two incidents every year.

Almost all of the “red alert” areas are concentrated in Uttara Kannada, Chikkmagaluru, Shivamogga and Chamarajanagar districts. As temperature rises at the end of January, so does the risk of forest fires, requiring officials to be on vigil till the end of summer.

After an investigation into the Bandipur blaze revealed that faulty fire lines and poor supervision were the reason for the spread of the fire, the department has come up with a multi-pronged approach to prevent similar incidents this year.

“After the Bandipur incident, we have created a fire cell and a standard operating procedure (SOP) which everyone has to follow. Firstly, a fire management plan is prepared and approved by a competent authority.

The SOP has well defined firelines which have to be executed by December-end and burning must be completed by January 15,”  Principal Chief Conservator of Forests (Head of Forest Force) Punati Sridhar told DH.

He said that to ensure its strict implementation, GPS readings of firelines are to be submitted for random verification.

“All the required equipment from fire jackets to shoes, gloves, backpack sprayers and tractors mounted with 2,000-5,000 litre tanks with high pressure pumps will be deployed at vantage points,” he said.

In addition, the department’s fire cell works in collaboration with the Karnataka State Remote Sensing Applications Centre (KSRSAC) to give fire alerts within half and hour of an area catching fire and detected by satellites.

“Earlier, the gap used to be four hours by when the fire would have spread beyond control. Now, with reduced time gap, it would be easier to control fire early,” he added.

Bengaluru, Jul 4: Karnataka on Saturday reported its biggest single day spike of 1,839 new COVID-19 cases and 42 related fatalities, taking the total number of infections in the state to 21,549 and the death count to 335, the Health department said.

The day also saw 439 patients getting discharged after recovery; even as 226 patients in the state were undergoing treatment in ICU.

Out of 1,839 fresh cases reported on Saturday, a whopping 1,172 cases were from Bengaluru Urban alone; while 24 of the 42 deaths were from the capital city.

The previous biggest single day spike was recorded on July 3 with 1,694 cases.

As of July 4 evening, cumulatively 21,549 COVID-19 positive cases have been confirmed in the state, which includes 335 deaths and 9,244 discharges, the Health department said in its bulletin.

It said, out of 11,966 active cases, 11,740 patients are in isolation at designated hospitals and are stable, while 226 are in ICU.

Among the 42 dead are six from Bidar, four from Dakshina Kannada, three each from Kalaburagi and Dharwad and one each from Hassan and Bengaluru rural.

Of the 42, twenty-six are men, the bulletin said, adding most of them were with a history of Severe Acute Respiratory Infection (SARI), Influenza-like illness (ILI).

Out of 1,839 cases tested positive today, contacts of the majority of the cases are still under tracing.

Among the districts where the new cases were reported, Bengaluru Urban accounted for 1,172 cases, followed by Dakshina Kannada (75), Ballari (73), Bidar (51), Dharwad (45), Raichur (41), Mysuru (38), thirty seven each from Kalaburagi and Vijayapura, thirty-five each from Mandya and Uttara Kannada.

Bengaluru Urban district tops the list of positive cases, with a total of 8,345 infections, followed by Kalaburagi 1,597 and Udupi 1,276.

Among discharges, Kalaburagi tops the list with 1,189 followed by Udupi (1,103) and Bengaluru Urban (965).

A total of 6,89,526 samples were tested so far, of which 17,592 were tested on Saturday alone.

So far 6,50,876 samples have been reported as negative, and of them 15,294 were reported negative 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.
