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”.

Bengaluru: An eight-month old baby has been detected with the human metapneumovirus (HMPV) in a Bengaluru hospital on Monday, with reports going viral online. This is likely the first reported case of HMPV in the country after the recent spike in China.

The baby is reportedly undergoing treatment in a private hospital in northern Bengaluru.

The Karnataka state health department has maintained that there is no cause for concern.

"We don't know what strain of virus is spreading in China. Without knowing that, we cannot say that this reported case is concerning. We have been reviewing all influenza-like illnesses (ILIs) from December to check for any strain that is concerning. There is no such concerning spike across the state or country," said a well-placed source in the state health department.

The HMPV is a known virus (first discovered in 2001) that causes respiratory symptoms similar to that of a common cold, largely affecting children below the age of five. It is not a new virus.

Cases have been reported in the past, especially in the winter season, note experts and health department officials, making it not an immediate concern, unless an unusual spike is observed.

In December 2024, 714 suspected cases of HMPV were tested in 16 Virus Research and Diagnostic Laboratories (VRDLs) across the country, of which only nine were confirmed positive.

Mangaluru: Air India Express (AIE) has postponed its much-anticipated direct flight service between Mangaluru International Airport (MIA) and Singapore, citing low bookings. Passengers who had booked tickets for the inaugural flight scheduled for January 21 and subsequent dates have been notified of the cancellation through email.

In its email, AIE assured passengers of alternative travel arrangements, including connecting flight options between MIA and Singapore. However, the decision to delay the direct service has left travelers and travel agents disappointed.

An AIE official attributed the postponement to operational challenges but clarified that the airline has not abandoned plans for the route. “We are committed to starting the service, but there is no immediate confirmation on the new launch date,” the official stated. He further explained that sustaining a route requires consistent demand, and seasonal travel alone is insufficient to justify operations.

Another AIE representative admitted that the number of bookings for the inaugural flight was below expectations but declined to disclose specific figures.

Rajesh H Acharya, director of HQ Connections Pte Ltd in Singapore and coordinator of the Singapore Tuluver community, expressed his disappointment. Acharya, who has been advocating for a direct flight between Mangaluru and Singapore since 2017, said, “After years of effort, we finally convinced the airline to start this service, but it has now been deferred.”

Taking to X (formerly Twitter), Acharya posted: "Did not expect such behavior from @AirIndiaX, now owned by @TataCompanies & @SIAirlines. If there are issues, travelers deserve to be informed well in advance. This decision needs investigation at the highest level."

The delay has raised questions among the travel community, with many hoping the airline will address these concerns and provide a clear timeline for the launch of the Mangaluru-Singapore direct flight.

Mangaluru: In a shocking case of fraud, six individuals posing as officials from the Enforcement Directorate (ED) swindled a beedi businessman of Rs 25 to 30 lakh in cash and five mobile phones at Kolnad in Bantwal taluk of Dakshina Kannada on Friday night.

The incident came to light after Mohammed Iqbal, 27, lodged a complaint with the police, stating that his father, a beedi trader, was targeted by the imposters.

According to the complaint, the six accused arrived at the businessman’s residence around 8:10 pm in a car with Tamil Nadu registration plates. Claiming to be ED officials, they announced that they had orders to search the house and began confiscating mobile phones from the family members.

The fraudsters reportedly discovered Rs 25 lakh to Rs 30 lakh in cash, which the businessman had kept aside for business purposes. They claimed that keeping such a large amount was illegal and threatened to arrest him unless he complied. By 10:30 pm, the group left the house, instructing the businessman to submit documents at the ED office in Bengaluru to reclaim the money.

Later, upon discussing the incident with his family, Iqbal realized that the individuals were not ED officials but fraudsters who had impersonated authorities to rob them.

A case has been registered at Vittal Police Station under relevant sections of the Indian Penal Code. An investigation is underway, and the police have promised swift action to apprehend the culprits.

Dakshina Kannada Superintendent of Police Yathish N, along with senior officers, visited the crime scene and assured the family that the perpetrators would be brought to justice at the earliest.
