Terrorism caused by distortion of religion, misguided belief: Swaraj tells OIC

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, Mar 29: Mosques across Karnataka are now turning into centers to create awareness against deadly coronavirus that cause Covid-19. 

The state government's board of auqaf has issued a notification to the administrations of all mosques to use their loud speakers to create awareness against the virus. 

All the mosques in the state have already suspended congregational prayers to prevent the spread of the virus.

As per the decision of the state board of auqaf, now all mosques have to play the audio clips that creates awareness against the virus in three languages. 

The clips will be played at 10 a.m., 4 p.m., 6 p.m. and 8 p.m. everyday.

Mysuru, May 15: The Temple Town of Nanjangud was till now treated as one unit or a Cluster Containment Zone and was put under complete lock-down as per the containment protocol listed under COVID-19 regulations and Disaster Management Act, 2005.

However on Friday, some of the restrictions have been lifted by Mysuru Deputy Commissioner Abhiram G Sankar who permitted certain activities as no fresh positive cases were reported from the cluster area. The Cluster Containment Zone was declared on March 29 following one employee of Nanjangud-based Jubilant Generics tested positive for the killer Coronavirus. As there were chances of the positive person spreading the disease to other employees of the factory, the cluster rules were enforced. Moreover, there were over 1,000 employees in the Pharma Company and a majority of them lived in and around Nanjangud.

The declaration of Cluster Containment Zone with complete lock-down and quarantining of all the Pharma Company employees proved a success to the District Administration as whoever tested positive – over 73 were later tested positive — had already been quarantined and the dangerous community spread phase was successfully prevented. To a major extent, the Corona virus curve has been flattened. As such, restrictions have been relaxed a bit on Friday.
