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”.

Israel began a third day of strikes in southern Lebanon on Wednesday, hours after Hezbollah confirmed the death of a senior commander in an airstrike on Beirut and a Lebanese minister said only Washington could help end the fighting.

Lebanese media reported that Israeli airstrikes had targeted several areas in the country’s south, beginning at around 5am, causing unspecified casualties.

Hezbollah meanwhile said it had launched a rocket targeting Mossad headquarters near Tel Aviv. Sirens had sounded in the Israeli city early on Wednesday, sending residents into bomb shelters, however the Israeli military later said it had intercepted the missile and no casualties or damage were reported.

Earlier on Wednesday, Hezbollah had confirmed that senior commander Ibrahim Qubaisi was among six people killed by an Israeli airstrike on an apartment block in the Lebanese capital Beirut on Tuesday, as Israel had claimed earlier. Israel said Qubaisi headed the group’s missile and rocket force.

Israel’s offensive since Monday morning has killed 569 people, including 50 children, and wounded 1,835 in Lebanon, health minister Firass Abiad told Al Jazeera Mubasher TV. Tuesday’s attacks came after Monday’s barrages racked up the highest death toll in any single day in Lebanon since the 15-year civil war that started in 1975.

Israel’s new offensive against Hezbollah has stoked fears that nearly a year of conflict between Israel and the militant Palestinian group Hamas in Gaza is escalating and could destabilise the Middle East. Britain urged its nationals to leave Lebanon and said it was moving 700 troops to Cyprus to help its citizens evacuate.

The UN security council said it would meet on Wednesday to discuss the conflict.

“Lebanon is at the brink. The people of Lebanon – the people of Israel – and the people of the world – cannot afford Lebanon to become another Gaza,” UN secretary general António Guterres said.

At the UN, which is holding its general assembly this week, US President Joe Biden made a plea for calm. “Full-scale war is not in anyone’s interest. Even if a situation has escalated, a diplomatic solution is still possible,” he said.

Lebanon’s foreign minister Abdallah Bou Habib criticised Biden’s address as “not strong, not promising” and said the US was the only country “that can really make a difference in the Middle East and with regard to Lebanon.” Washington is Israel’s longtime ally and biggest arms supplier.

The US “is the key … to our salvation,” he told an event in New York City hosted by the Carnegie Endowment for International Peace.

Up to half a million people are estimated to have been displaced in Lebanon, said Bou Habib. He said Lebanon’s prime minister hoped to meet with US officials over the next two days.

In Lebanon, displaced families slept in shelters hastily set up in schools in Beirut and the coastal city of Sidon. With hotels quickly booked to capacity or rooms priced beyond the means of many families, those who did not find shelter slept in their cars, in parks or along the seaside.

Fatima Chehab, who came with her three daughters from the area of Nabatieh, said her family had been displaced twice in quick succession.

Udupi: A vigilant Railway Protection Force (RPF) constable, Aparna K T, demonstrated remarkable presence of mind when she rescued a student who slipped while trying to board a moving train at Udupi Railway Station on Friday morning.

The incident occurred as passenger train number 06602 arrived at the station around 7:30 AM. The student, traveling from Mangaluru to Gokarna, had briefly alighted to purchase snacks. However, as the train began moving, she hurried back towards the carriage with the snacks in hand. In her rush, she lost her footing, slipping dangerously between the platform and the moving train.

Woman constable Aparna K T was given a cash reward of Rs 5000.

 

Constable Aparna, who had been closely monitoring the passengers, immediately sprang into action. “I saw her running towards the train and alerted everyone by blowing my whistle. She slipped, and her legs were caught between the platform and the train. Without hesitation, I pulled her out with the help of others nearby,” she recalled.

Thanks to Aparna’s quick thinking and the swift response of the railway staff, the train was stopped in time. Railway personnel, including the guard and loco pilot, were immediately informed, and they acted promptly to halt the train using both flag signals and a walkie-talkie.

RPF Inspector Madhusoodhanan PV arrived at the scene shortly after to check on the passenger's condition. The shaken but uninjured student was given water and helped back onto the train to safely continue her journey.

In an added measure of care, the RPF post at Bhatkal was notified to follow up on the passenger’s well-being during her journey. The student, fortunately, reached her destination without further incident.

The heroic rescue was captured on CCTV and has since gone viral on social media, earning widespread praise. In recognition of her bravery, Regional Railway Manager (RRM) Karwar awarded Constable Aparna a cash reward of ₹5,000, commending her quick action that averted a potentially tragic accident.

At least 20 people have been killed as more communication devices detonated in Lebanon a day after simultaneous explosions of pagers across the country left at least a dozen dead and thousands injured.

Explosions were reported in multiple locations in Lebanon, including at the site of a funeral for a child killed in a pager explosion the previous day.

Media reports said that several blasts occurred simultaneously in Beirut similar to what happened on Tuesday. Several explosions were also reported in southern and eastern Lebanon.

Lebanon’s Health Ministry said at least 20 people were killed and more than 450 injured in the new wave of explosions. 

An informed source said that the detonated devices came from the same batch of cargo as the detonated pagers, all imported from the same company.

The Lebanese Army Command called on the people not to gather in the scenes of security incidents to allow the arrival of medical teams.

Civil defense teams are extinguishing the fires that broke out as a result of the explosions, while ambulance teams continue to transport the injured.

The new act of aggression came as top Hezbollah official Sayyed Hashem Saffieddine was delivering a speech affirming that the Israeli acts of terrorism will have their own punishment, stating that the resistance is steadfast and capable of inflicting more defeats on the enemy.

The Hezbollah official said a speech by the movement’s Secretary-General Sayyed Hassan Nasrallah, planned for Thursday, will clarify matters and that the movement will face a new pattern and a new confrontation with the enemy.

Thousands of pagers widely used by resistance factions and also public service workers exploded on Tuesday, leaving at least a dozen dead and around 3,000 people injured.

The Lebanese government has blamed Israel. Hezbollah has promised the Israeli regime will receive ‘just punishment’ for the attacks.

Taiwanese company Gold Apollo said the pagers used in the Israeli deadly terrorist attack on Tuesday had been made by a Hungarian firm, to which the company had authorized its brand on the devices.

The company made the remarks in a statement on Wednesday, identifying the firm as BAC Consulting KFT based in the Hungarian capital Budapest.

The UN Security Council is due to meet on Friday to discuss the latest blasts that hit Lebanon, council president Slovenia said on Wednesday after Lebanon requested an emergency meeting.

UN Secretary-General Antonio Guterres said Wednesday that civilian objects should not be weaponized.

"I think it's very important that there is an effective control of civilian objects, not to weaponize civilian objects -- that should be a rule that... governments should, be able to implement," Guterres said at a briefing at UN headquarters.

"As important as the event in itself, is the indication that this event confirms that there is a serious risk of a dramatic escalation in Lebanon -- and everything must be done to avoid the escalation," he said.

"What has happened is particularly serious, not only because of the number of victims that it caused, but because of the indications that exist that this was triggered, I would say, in advance of a normal way to trigger these things, because there was a risk of this being discovered."

The Euro-Mediterranean Human Rights Monitor described the detonation of pagers and wireless devices in Lebanon on Tuesday and Wednesday as a blatant violation of international law.

The organization said the attack did not only target Hezbollah members but also indiscriminately exploded devices used by civilians.

The timing of the attack indicates that Israel did not take necessary precautions, as it occurred when device users were at home with their families, leading to numerous severe civilian injuries, including children, it said.

Israel's actions constitute a flagrant violation of international humanitarian law, which prohibits indiscriminate attacks and the targeting of civilians and their property, and mandates that warring parties distinguish between civilians and combatants at all times, the rights monitor said.

The organization called for an urgent and independent international investigation into these attacks and pressure on Israel to immediately stop its crimes and prevent further escalation in the region.
