Karnataka to do pooled covid-19 tests to reduce costs

Agencies

Bengaluru, Oct 24: The state government hopes to save costs on Covid testing by adopting pooled sampling. In this process, instead of testing just one sample in one test tube, five samples are used.

However, this can be done only when there are greater chances of samples being negative, since, if a sample pool tests positive, then each sample has to be individually tested again.

Now, with 10 districts of Bidar, Gadag, Raichur, Koppal, Kalaburagi, Yadgir, Ramanagara, Shivamogga, Chamarajanagar, and Kolar, having less than 5% weekly positivity rate, the state has allowed pooled sampling here.

However, in the rest of the 20 districts, individual tests will continue till they have a weekly average positivity rate of less than 5%. The government pays Rs 800 for every sample’s RTPCR test in a private lab. In Karnataka, 65% of labs are private and more than one lakh tests are done at government and private labs.

In Ramanagara district, which has a TPR of 4.1%, district surveillance officer Dr Kiran Shankar said, “We have a target of testing 800 samples with RT PCR everyday.”

“While pooling samples, we will make sure they are of low risk categories and not SARI, ILI or of patients with comorbidities. In pooling, the cost incurred on reagents added to samples and consumables will come down,” he said.

“Earlier, we would test only 96 samples in one cycle, which would take two-and-a-half hours. Now, we can pool and test 480 samples and get the results in a short time.”

Dr C N Manjunath, state nodal officer for Covid-19 testing, explained the process. “If Ramanagara has a target of testing 800 samples everyday via RT PCR, instead of using 800 test tubes for 800 samples separately, 160 tubes will hold 800 samples as each tube will have five samples.”

Dr V Ravi, Senior Professor and Head, Neurovirology, Nimhans, and member of State Covid-19 Technical Advisory Committee, told DH, “Increased volume and decreased costs are the benefits of pooled testing. Cost is reduced while doing RNA extraction.”

Koppal has so far done 75,235 RT PCR tests. It’s weekly test positivity rate (TPR) is 3.7%. Vikas Kishor Suralkar, deputy commissioner, Koppal told DH, “We have been pooling samples even when our TPR was more than 5%. But I agree that the likelihood of a positive pool is less when the TPR is less than 5%. Even if some pools should come positive and we have to test all five samples individually again, one extra test doesn’t increase the cost much. But avoiding five individual tests, when a pool comes negative,  greatly reduces the cost.”

Journalist Mohammad Hijazi has been killed in an Israeli attack, raising the number of media workers killed by Zionist forces since the start of the war on Gaza to 220.

The Israeli regime forces killed the Palestinian writer, poet and journalist in an airstrike on northern Gaza’s Jabalia refugee camp, according to his family.

He was among nearly 90 other Palestinians killed in Israeli bombardment across the besieged territory in the last 24 hours, according to a Gaza Health Ministry statement on Sunday.

“I don’t know if I will write to you again. I keep what I have written and am writing. Maybe it will come to light one day. I refuse a cheap death. I curse the murderer,” Hijazi wrote in a post on social media in August 2023.

“Let us in this bottom that we have finally reached, arm ourselves with patience and prayer, and count the days we have lived as a historic achievement while awaiting what is coming with a broken heart, an extinguished eye, a head held high, and a spirit that fights until the end of the road.”

Since the Israeli killing machine imposed a military siege of northern Gaza in early October intensifying its bombing attacks on the the Jabalia camp, hundreds of people have been killed.

Gaza’s Health Ministry reported on Sunday that at least 88 Palestinians had been killed and 208 others injured in the past 24 hours alone.

According to media reports from central Gaza, among those killed in the latest Israeli strikes across Gaza on Sunday were three Palestinians who were living in a tent in Deir el-Balah.

A family of 15 people was also buried under the rubble in Gaza City, following a separate strike, media reported.

The Israeli regime launched its genocidal war on the Gaza Strip following a surprise operation by the Palestinian  Hamas resistance movement in October last year, killing more than 45,805 Palestinians and wounding 109,064 others.

Another Palestinian journalist has been killed in an Israeli attack in the Gaza Strip, taking the death toll to 205 since early October 2023 when the occupying Tel Aviv regime launched its all-out onslaught against the blockaded coastal sliver.

Local organizations identified the new victim as Ahlam al-Nafed, who recently reported from the besieged Indonesian Hospital in northern Gaza for Drop Site News and other media outlets.

She was killed on Tuesday as she was walking to al-Shifa Hospital – the largest medical complex and central hospital in the Gaza Strip, and located in the neighborhood of northern Rimal in Gaza City.

“For the past 100 days, Ahlam chronicled the genocide in northern Gaza, capturing evidence of Israeli war crimes from the besieged Indonesian Hospital.

“Through her words and images, she ensured that atrocities which might have been silenced were brought to light, allowing the world to witness the brutal reality unfolding there,” Drop Site News wrote in a statement published on its X account on Tuesday.

It underlined that Ahlam’s work documenting the attacks on the Indonesian Hospital was irreplaceable.

“She was one of the last remaining voices in northern Gaza — a voice the world desperately needed. Without her, the full extent of Israel’s actions might never have been known,” the statement also read.

For its part, the Indonesian Hospital said, “Ahlam courageously documented the genocide in north Gaza, residing in the medical facility during its siege, taking evidence of war crimes and bearing witness to tell the story with her pictures and her words, many of which we shared with you.”

Journalists working within the Palestinian territory face heightened risks while covering the genocidal war, particularly in light of Israeli ground assaults and airstrikes, as well as challenges such as disrupted communications, shortages of supplies, and power outages.

In the face of these difficulties, Palestinian journalists have continued to document the atrocities of the war, acting as the global community's eyes and ears throughout one of the most deadly wars of the 21st century.

Backed by the United States and its Western allies, Israel launched the war on Gaza on October 7, 2023, after the Palestinian resistance movement Hamas carried out Operation Al-Aqsa Flood against the Israeli regime in response to its decades-long campaign of oppression against Palestinians.

The regime’s bloody onslaught on Gaza has so far killed at least 46,645 Palestinians, mostly women and children, and injured 110,012 others. Thousands more are also missing and presumed dead under rubble.

On November 21 last year, the International Criminal Court (ICC) issued arrest warrants for Israeli prime minister Benjamin Netanyahu and former minister of military affairs Yoav Gallant for war crimes and crimes against humanity in Gaza.

Karnataka’s first C Band Doppler Weather Radar (DWR) in Mangaluru, work for which was supposed to have been finished by January 15, will be postponed slightly due to some technical difficulties, said N Puviarasan, head of India Meteorological Department (IMD)’s Bengaluru centre.

“We are hoping to get it running by this month's end at least,” said Puviarasan on the sidelines of a stakeholders’ workshop organised by the IMD Bengaluru on January 4 to commemorate 150 years of IMD. The workshop was held at the premises of Karnataka State Natural Disaster Management Centre (KSNDMC) and had day-long sessions, including technical ones by Hindustan Aeronautics Ltd, Bengaluru and Department of Agro Meteorology, University of Agricultural Sciences, Bengaluru.

Puviarasan also said the IMD ran into obstacles in its bid to establish a S-band DWR in Bengaluru, due to problems in acquiring the land required. “We need 30X30 space to put up a tower and a small utility room,” said Puviarasan. According to him, IMD had originally planned to put up the radar in Nandi Hills. But, on Union Minister of State for Micro, Small and Medium Enterprises and Labour & Employment Shobha Karandlaje’s request, he said they started scouting for an appropriate place in Bengaluru. On July 23, 2024 Karandlaje had posted on X: “Following my request, the IMD has greenlit the installation of a Doppler radar in the city (Bengaluru), scheduled to be operational by year-end. This is a major step towards better weather forecasting & preparedness for natural disasters."

She had also posted a letter written to her by Union Minister of State (Independent Charge) Jitendra Singh, who said the radar will have an operational range of 250 km and will be installed in Bengaluru by 2024. He also mentioned that the site for the radar installation has already been identified and the Centre had informed the state government to acquire the site. “But the site suggested by the minister is not feasible because of the elevation issues,” said Puviarsan.

According to IMD scientists, there should not be buildings higher than the radar within its range, as readings will be affected. Puviarasan said they have now identified a place within a government school in Bengaluru and are awaiting permission to establish the radar. He said usually land acquisition is a huge problem. “This time, it’s a government school. Here, we don’t even need to raise a boundary wall, as it exists already. So, we’ll see,” said the director. If this is not working out, he said IMD will go back to its initial plan and will establish the radar in Nandi Hills. Mangaluru radar, being established near Kadri, is expected to cover 250-300 km radius, putting regions prone to heavy rains during monsoons in Karnataka, like Agumbe, Hulikal, Talakaveri, Kerekatte and Bhagamandala within its range, said a IMD scientist. Earlier, in his presentation, Puviarasan had also said apart from Bengaluru and Mangaluru, one X-band DWR is coming up at Dharwad. He also said proposals have been submitted for S-band radar at Honnavara and C-band at Ballari.

Without a DWR, Karnataka has been depending on the radars in Goa, Hyderabad and Chennai for more accuracy in forecasts for thunderstorms and rainfall so far, said IMD officials. In his presentation, Director of KSNDMC, Bhoyar Harshal Narayanrao, talked about why Karnataka is vulnerable to hydro-meteorological and geological disasters. He also said 80 per cent of Karnataka is prone to drought, and that in the last 23 years (between 2001 and 2024), 16 years are drought affected. He also said maximum number of landslides leaving widespread damage and casualties have occurred in Uttara Kannada, Shivamogga, Chikkamamgaluru, Udupi, Dakshina Kannada, Kodagu, Hassan, Chamrajanagara Mysuru and Chikkaballapura. The year 2018 saw the most landslides, at 462, between 2006 and 2024. Narayanrao also said Karnataka is the only state in the south with its own disaster monitoring centre and seeing its success other states are also thinking of establishing one on the lines of KSNDMC. He said KSNDMC is also being approached by a few startups to involve Artificial Intelligence in disaster management. “We are taking a cautious approach towards the idea. We are looking into what AI can offer and will decide accordingly,” said Narayanrao.

Other presentations included an overview of IMD services by S Balachandran, head of Regional Meteorological Centre, Chennai and possible integration of climate services in support of Karnataka State Action Plan on climate change by K J Ramesh, Former Director General, IMD. Sanjeev Verma, AGM, Air Traffic Management, Airports Authority of India, Kempegowda International Airport, Bengaluru also made a presentation of how weather forecasting is integral for air traffic management.
