Tension grips Mangalore after Bajrang Dal activists stab one, assault five other Muslim students

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.

Mangaluru, Apr 3: The laboratory at District Wenlock Hospital has initiated trial for Covid 19 testing, close on the heels of receiving permission from state government.

Doctors, elected representatives and stakeholders had repeatedly demanded that a laboratory should be set up in the port city. Without the lab, the samples were sent either to Shivamogga or to Bengaluru for testing. When Heath Minister Sriramulu had visited Mangaluru on March 17, he had promised a lab in the city for testing of the samples.

Accordingly, the government gave permission for starting the laboratory at Wenlock Hospital. The process of registering the lab with Indian Council for Medical Research (ICMR) will be completed shortly. The laboratory will be fully operational only after it is registered.

Bengaluru, Jun 7: A mobile app and a portal offering technology-driven solutions to manage and mitigate floods in urban areas were launched here on Saturday by Karnataka Revenue Minister R Ashoka.

The mobile app 'Bengaluru Megha Sandesha' was developed to disseminate information on rainfall and flood forecast, location-specific dynamic weather directly to the public. "The in-built features of the app and the information provided for a city is the first of its kind in the country," a press release said. This is a system of providing rainfall, flood forecasts and early warning to the officials of government agencies in the city through SMS to their mobile phones, social media platforms and a dedicated web portal, the release said.

The information provided would help the civic authorities act in advance and manage the floods, it said. The portal 'Varunamitra' is for information on the weather. The information provided is based on real-time data from 100 telemetric rain gauges installed and maintained at various locations across the state, it said. Rainfall forecast is based on the weather research and forecast models developed by the Indian Space Research Organisation (ISRO), Ahmedabad, the release said.

The information on flood forecast is based on the hydrological model, hydraulic routing and automation of the results. The Karnataka State Natural Disaster Monitoring Centre, along with the Indian Institute of Science (IISc), took up this project on the urban flood model for Bengaluru city. The project was funded by the Central government's department of science and technology, the release added.
