Fisherman feared dead; search operation called off

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 11: Karnataka Pradesh Congress Committee (KPCC) president D K Shivakumar on Saturday lodged a complaint with Director General and Inspector General of Police Praveen Sood seeking action against four BJP leaders for their alleged communal statements.

In his petition, Mr Shivakumar cited remarks made by BJP MP Shobha Karandlaje, former union minister Anant kumar Hegde, MP Renukacharya and MLA Basanagouda Patil Yatnal were ''vituperative statements'' which were offences under Section 153A of the IPC.

The Congress leader alleged that the four leaders ''joined in a criminal conspiracy to create enmity between Hindus and the minority community.''

Bengaluru, Jan 31: Karnataka Chief Minister B S Yediyurappa on Friday got the green signal from the BJP central leadership for the much-awaited cabinet expansion in the state and he is mostly likely to induct 11 ministers. Yediyurappa said the date of swearing-in will be decided in a day or two, although he indicated that it would most likely be held on February 3.

Currently, there are 18 ministers, including the chief minister, in the cabinet that has a sanctioned strength of 34. Sixteen berths are vacant. "Many of our suggestions have been accepted by Home Minister Amit Shah and BJP national president J P Nadda. If there are differences, we will discuss in Bengaluru and finalise it," Yediyurappa told reporters after meeting Shah in the Parliament Complex here.

Except for one or two, most of the disqualified JDS-Congress MLAs who got re-elected in the bypolls on BJP tickets will be made ministers, he said, adding there won't be any additional deputy chief ministers. However, sources said, a total of 11 ministers would be inducted into the cabinet.

"We discussed yesterday and now also. Shah has agreed to almost everything," Yediyurappa said, adding he is returning back "happy" after getting the nod for the cabinet expansion. "I am going happy," he said.

Yediyurappa had been anxiously waiting for the party high command's approval to expand his ministry amid intense lobbying by the aspirants. Opposition parties have been critical of the BJP and Yediyurappa over the delay in the cabinet expansion, alleging he was weak and that his administration had collapsed.
