Karnataka govt may drop lessons on Tipu Sultan from text books

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, Jan 7: Karnataka Chief Minister BS Yediyurappa on Monday said the much-awaited cabinet expansion will take place in about a week to 10 days and that he wants to complete the exercise before his proposed visit to Davos to attend the World Economic Forum meet later this month.

"Cabinet expansion has to be done in a week or 8-10 days. There is also information that Amit Shah will be coming to Bengaluru on January 16 or 18. Before that I will go to Delhi and get things cleared and will expand the cabinet at the earliest," Mr Yediyurappa said.

Speaking to reporters in Bengaluru, he said he wanted to complete the exercise before his Davos visit.

"I will make all efforts to expand the cabinet before that," he said.

With Mr Yediyurappa making it clear that 11 of the disqualified JDS-Congress MLAs who got re-elected in the December 5 bypolls on BJP tickets will be made ministers, lobbying has been on within the party for the remaining ministerial berths.

Currently, there are 18 ministers, including the Chief Minister, in the cabinet that has a sanctioned strength of 34.

Cabinet expansion will not be an easy task for the Chief Minister as he will have to strike a balance by accommodating the victorious disqualified legislators as promised and also make space for the old guards, upset at being "neglected" in the first round of the induction exercise.

He also has to give adequate representation to various castes and regions in his cabinet and also deal with the allocation of key portfolios.

The Chief Minister, who has indicated that the ministry expansion may take place any time after Sankranti, is likely to travel to Davos on January 20, according to sources.

BS Yediyurappa, along with Union ministers Piyush Goyal and Mansukh Mandaviya, as well as Chief Ministers Amarinder Singh, Kamal Nath, are expected to join over 100 Indian CEOs at Davos in Switzerland later this month for the WEF's 50th annual meeting, which will be attended by thousands from across the globe.
