Abu Dhabi: Bearys Welfare Forum hosts iftar get-together-2018

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, Apr 12: A 10-month-old baby who tested COVID-19 positive on March 27 completed treatment and discharged from hospital on Saturday.

He was the youngest positive case in Karnataka, from Sajipanadu village in Bantwal taluk.

The child had been with his mother to a relative's house at Monetepadau village, situated on the Karnataka-Kerala border in the first week of March.

A few days later the child developed an acute respiratory illness and tested positive for the COVID-19 virus.

Treating the breastfeeding child was challenging for doctors as he had to be isolated. A team of doctors from Wenlock Hospital took up this challenge and successfully cured the baby.

Test reports on his mother and grandmother too have returned negative. They too had been under quarantine and were discharged with the baby.

Another positive development was that no COVID-19 case has been reported from the child's village.  

The entire Sajipanadu village was completely sealed after the child tested positive and the district had provided all the necessary supplies to the villagers.

Udupi, Jul 22: Deputy Commissioner G Jagadeesh on Wednesday announced lifting of ban on movement of people and vehicles with immediate effect in the borders of Kerala which was banned during lockdown.

The announcement comes hours after Karnataka Chief Minister B S Yediyurappa announced that lockdown in Bengaluru and other parts of the state will not be extended any further, suggesting people should wear masks and maintain physical distancing strictly.

Mr Jagadeesh noted that although the seal down of the borders of the district would be lifted, checkposts on the border would be set up and urged people to enter the district only in case of emergency.
