Bengaluru, Nov 10: A whopping 44.5% of Karnataka’s population was infected with Covid-19 by the end of August, said a team of Indian and American researchers who completed a randomised Covid-19 testing study.

This estimate stands in sharp contrast to the state’s official sero-survey which determined that 27.3% of the population was exposed to the virus. The diverging studies appear to suggest that this is because the state’s sero-survey did not conduct enough random tests.

The survey, titled “Karnataka Seroprevalence Study” (KSS), began on June 15 and ended on August 29. It saw researchers from Duke University in North Carolina, the University of Chicago, the Centre for Monitoring Indian Economy (CMIE) and Mapmygenome, supported by the State Covid Task Force, reach out to 1,907 random households across 20 districts of Karnataka.

The homes were identified from an existing and representative sample of 9,717 households, drawn from the Pyramids Household Survey (CPHS), a longitudinal household panel data set assembled by the Mumbai-based Centre for Monitoring Indian Economy (CMIE).

The survey has now estimated that a shocking 3.15 crore residents had been infected by the virus by the end of August 2020, which is higher than the figure of 1.93 crore persons currently infected or recovered from Covid according to the government survey.

Another key finding is that rural areas have been hit equally badly as urban areas because of returning migrants and because there were fewer lockdowns there due to ongoing agricultural activities.

Commissioner of Health Pankaj Kumar Pandey said the disparity in findings could be due to KSS’ small sample size.

 “A small sample size can skew estimates. Plus the KSS’ use of households sourced from an economic survey can create a distorted picture. The state’s sero-survey results, meantime, have tallied largely with nationwide sero-survey results,” he said.

One of the authors of the KSS study, Associate Professor Manoj Mohanan of the Sanford School of Public Policy at Duke, told DH that one reason for the disparity is the different strategies used.

“We aimed to get at the population-representative sample while the state’s study focused on target-risk groups. This is likely to cause some variation, especially because consent rates are likely to differ,” he said.

That the studies used different antibody tests is also a factor, he added. “We relied on the Elisa test for the RBD spike protein that was developed by THSTI while the other study relied on the Covid Kavach Elisa,” he said.

Scientists of the DBT India Consortium for Covid-19 Research had published a paper in August showing that the ICMR-designed Covid Kavach Elisa test has a specificity of 99.5% and a sensitivity of 75.7%. In contrast, THSTI’s Elisa test was shown to have a specificity of 100% and a sensitivity of 84.7%.

“Sensitivity” is the ability to identify those with antibodies to Sars-Cov-2 (true positive rate), and “specificity” is the ability to identify those without antibodies to Sars-CoV-2 (true negative rate).

Professor Mohanan also pointed out that the RT-PCR positive rates in the state’s sero-survey (12.7%) are “slightly higher than the high-end of our estimates for current infection”.

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.

Mangaluru: Dakshina Kannada MP Captain Brijesh Chowta met Union Home Minister Amit Shah in New Delhi on Friday to discuss key issues affecting the security and development of the region. The meeting highlighted several urgent concerns, ranging from counter-terrorism measures to infrastructure upgrades.

During the meeting, Chowta strongly advocated for establishing a National Investigation Agency (NIA) Centre in Mangaluru. He pointed out the city’s vulnerability to threats such as Islamic radicalisation, sleeper cells, and the activities of groups like SDPI and PFI. Citing the unrest during the Citizenship Amendment Act (CAA) protests, Chowta emphasized the ability of radical groups to incite large-scale disruptions. He argued that Mangaluru’s strategic coastal location necessitates an NIA Centre to bolster counter-terrorism operations and ensure regional security.

Chowta also discussed the Indian Coast Guard Academy, sanctioned for Mangaluru in 2020. He highlighted its potential to enhance India’s maritime security through advanced training in coastal defence, disaster response, and surveillance. Situated near the Arabian Sea and Mangalore Port, the academy is strategically positioned to address challenges in regions like Lakshadweep and the Maldives, aligning with India’s geostrategic interests.

The MP proposed the establishment of a Sainik School in Mangaluru to nurture leadership, discipline, and patriotism among local youth. He emphasized that such an institution would not only provide quality education but also act as a feeder for the armed forces, enhancing the region’s defence readiness. Chowta suggested pairing the school with a military installation, further strengthening coastal defence capabilities and supporting national security goals.

Addressing infrastructure, Chowta underscored the need to improve the Mangaluru-Bengaluru railway and road networks. He argued that enhanced connectivity would unlock the region’s economic potential, streamline logistics for New Mangalore Port, and support key industries such as fisheries, agriculture, and manufacturing. Additionally, upgraded infrastructure would boost trade, tourism, and employment opportunities.

On economic development, Chowta urged the revival of cooperative banks under the Ministry of Cooperatives. He proposed increased funding and loan facilities for businesses and farmers to enhance financial inclusion and regional economic stability. Strengthening fisheries cooperatives, he noted, would provide local fishermen with better access to financial services, loans, and insurance, improving productivity and security.

The MP’s discussions reflected a comprehensive vision for balancing security, infrastructure, and economic growth in Dakshina Kannada, aligning with both regional and national priorities.

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.
