Saudi: Umrah-bound Bhatkal family meets with accident; 2 killed; 5 injured

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, Jul 23: The Siddi community in Karnataka got its first lawmaker as Governor Vajubhai Vala nominated five persons, including Shantharama Budna Siddi, to the Karnataka Legislative Council on Wednesday.

Shantharama Siddi had been working as a social worker and was a post holder at the Vanavasi Kalyan Prakalpa, a tribal welfare initiative of the Rashtriya Swayamsevak Sangh (RSS).

The Siddis, an ethnic group in India, are said to have descended from the people of the East African region. They are included in the list of Scheduled Tribes (ST) in Karnataka.

Apart from the Shantharama, the inclusion of CP Yogishwar, who had left Congress to join BJP in 2017 but failed to retain his seat in the 2018 Assembly polls, is also considered as a big decision.

Adagur H Vishwanath, another former JDS leader, who had quit his party and joined BJP but failed to retain his seat has also caught the attention of the people.

Further, Governor Vala has nominated Talwar Sabanna and Bharathi Shetty to the Upper House in the state.
