3-year-old girl killed in hit-and-run accident; locals catch driver

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.

Udupi, May 4: Udupi Deputy Commissioner G Jagadeesha said that mechanised boat fishing will be permitted in Udupi district in another two days.

He further said that the decision was taken after the district was declared as a Green Zone as no fresh cases of COVID-19 were reported from the district in the past several days.

The Deputy Commissioner told the media here that fishing will be permitted but social distancing has to be practised and only 30 boats will be permitted in a day.

Bengaluru, Jun 18: Two employees at a plant of Toyota Kirloskar Motor in Karnataka's Bidadi have tested positive for COVID-19, the automobile company said in a statement on Wednesday.

According to the auto major, the two employees had attended work on June 7 and 16 respectively.

"As a first step and through appropriate contact tracing, TKM has started identifying all those employees who may have had primary or secondary contact with the infected employees for necessary treatment and quarantine wherever necessary and is in contact with the local government authorities," the statement said.

Toyota Kirloskar Motors had restarted operations after weeks of nationwide lockdown to prevent the spread of coronavirus on May 26. It said that all necessary precautions were to maintain social distancing and all Central and state government directives were being followed.

"However, despite all such measures, two employees at TKM's Bidadi plant tested positive for COVID-19 on June 16th, 2020. Operations at TKM plant has already been temporarily suspended so that required disinfection can be carried out at the plant," the statement said.

"TKM has extended all necessary support to the infected employees for medical treatment as well as quarantine procedures. The company is in touch with the families of the infected employees so as to support them to handle this situation carefully without further complications," it added.
