Karnataka unsafe in Congress hands, says Smriti Irani

Bengaluru, Mar 31: With many departmental stores, shops and establishments insisting on people to wear masks, Karnataka government on Tuesday clarified that as a rule every one need not wear a mask.

The Commissionerate of Health and Family Welfare Services in an advisory said a person is suppose to wear mask only when he or she has symptoms of cold or cough or fever or any other respiratory problem.

It said a person who is caring for COVID-19 suspect or confirmed patient should wear mask. Also, a health worker who is attending to a patient with respiratory symptoms should wear a mask.

The advisory also noted that those treating or handling COVID-19 suspects or patients need to wear N95 mask, while others can wear triple layer surgical mask.

The advisory from the Commissionerate has come amid shops and establishments, also police on road insisting people to wear masks when they venture out.

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, Mar 16: As a precaution against the spread of Covid-19, the Karnataka State Road Transport Corporation (KSRTC) on Monday decided to cut down its premium, non-AC sleeper, Rajahamsa and express bus services from Mangaluru to Bengaluru and Kasaragod following poor patronage.

The cut down in services is as per the direction of KSRTC's Central office that wants bus services to be operated on priority.

KSRTC Mangaluru Divisional Controller S N Arun said that the corporation has decided to cut down 40 trips to Bengaluru. Concerning Kasaragod, it has reduced the number of trips from 40 to 35. "These include a reduction in services to Mysuru and Dharmasthala also," he added.
