Bengaluru, June 21: An assistant sub-inspector of police who was undergoing treatment for COVID-19 infection in city-based Victoria hospital passed away on the intervening night of Saturday and Sunday as he did not respond to the treatment for coronavirus.

The 59-year-old ASI was attached to the Wilson Garden traffic police station in Bengaluru. He tested positive for coronavirus on June 18 and was rushed to the COVID ward in Victoria hospital on June 19. He had fever for the last four days. His wife and two children have been quarantined. According to the police, the station has not yet been sealed down and no policemen have been quarantined.

The Wilson Garden ASI is the third Bengaluru police personnel to die of COVID-19 in the last one week. Earlier, an ASI from the VV Puram traffic police station had died undergoing treatment. On Saturday morning, a head constable from the Kalasipalya police station who was admitted at Victoria hospital passed away. The series of deaths in the police department has created fear among other policemen across the city.

One the other hand, dozens of policemen were tested positive in different parts of Karnataka today including 21 from two police stations of Bengaluru. 

Around 15 policemen from the Kalasipalya police station and five policemen from the Ashok Nagar traffic police station tested positive for coronavirus on Sunday.

In Kalasipalya, three ASIs, head constables and police constables have tested positive. In Ashok Nagar traffic police station, a probationary sub-inspector, an ASI, two police constables and a lady constable tested positive for the virus.

One more police constable working in Bandepalya police station also tested positive. Seven policemen who were in his primary contacts have been quarantined. BBMP officials have begun the process of fumigating the station premises and its surroundings.

San Diego, Apr 15: Several people lost their sense of smell or taste weeks ago globally and are still waiting for it to come back and now, researchers have identified an association between sensory loss and novel coronavirus 2019 (COVID-19) infection, indicating that loss of smell and taste may be considered as early symptoms of the deadly disease.

Interestingly, the study also found that persons who reported experiencing a sore throat more often tested negative for COVID-19.

The team from University of California-San Diego found high prevalence and unique presentation of certain sensory impairments in patients positive with COVID-19.

Of those who reported a loss of smell and taste, the loss was typically profound, not mild.

"Based on our study, if you have smell and taste loss, you are more than 10 times more likely to have COVID-19 infection than other causes of infection. The most common first sign of a COVID-19 infection remains fever, but fatigue and loss of smell and taste follow as other very common initial symptoms," explained study researcher Carol Yan from UC San Diego.

"We know COVID-19 is an extremely contagious virus. This study supports the need to be aware of smell and taste loss as early signs of COVID-19," Yan added.

For the findings, published in the journal International Forum of Allergy and Rhinology, the research team surveyed 1,480 patients with flu-like symptoms and concerns regarding potential COVID-19 infection who underwent testing at UC San Diego Health from March 3 through March 29, 2020.

Within that total, 102 patients tested positive for the virus and 1,378 tested negatives. The study included responses from 59 COVID-19-positive patients and 203 COVID-19-negative patients.

Encouragingly, the rate of recovery of smell and taste was high and occurred usually within two to four weeks of infection.

"Our study not only showed that the high incidence of smell and taste is specific to COVID-19 infection but we fortunately also found that for the majority of people sensory recovery was generally rapid," said Yan.

"Among the COVID-19 patients with smell loss, more than 70 per cent had reported improvement of smell at the time of the survey and of those who hadn't reported improvement, many had only been diagnosed recently," she added.

Sensory return typically matched the timing of disease recovery.

In an effort to decrease the risk of virus transmission, UC San Diego Health now includes loss of smell and taste as a screening requirement for visitors and staff, as well as a marker for testing patients who may be positive for the virus.

"It is our hope that with these findings other institutions will follow suit and not only list smell and taste loss as a symptom of COVID-19, but use it as a screening measure for the virus across the world," Yan said.

Bengaluru, Apr 18: The Karnataka government has fixed the cost of test for COVID-19 in private laboratories at Rs 2,250, an official said on Friday.

"Based on the discussions and negotiations, the cost per test has been fixed at Rs 2,250. This includes the screening test and a confirmatory test," said order by Health and Family Welfare Department's Additional Chief Secretary Jawaid Akhtar.

A total of 16 laboratories (11 government and 5 private) have been approved by the Indian Council of Medical Research (ICMR) for testing samples of possible COVID-19 cases in the state.

Realising that early detection of coronavirus cases and timely treatment was the need of the hour, meetings were held to rope in more private laboratories to conduct COVID-19 sample tests.

As per the protocol by the Centre, testing the samples of suspected COVID-19 cases can be taken up in private laboratories subject to conditions which include sharing the lab data pertaining to the diagnosis of COV1D-19 with the state government and with the ICMR on a timely basis.

As per the Union Health Ministry, 353 people have infected from coronavirus in the state of which 83 are cured and discharged and 13 succumbed to the virus.
