Is BJP ‘Beef Joy Party’ now? VHP asks after Parrikar’s assurances to beef eaters

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/Kasaragod, Jun 30: In what appears to be an ego clash between the officers of Karnataka and Kerala, around 150 Mangalureans including 12 pregnant women were evicted from the lodges in Kasaragod in the middle of the night and sent to Mangaluru.

Expressing shock over the incident, Mangaluru MLA U T Khader hit out at the authorities concerned for the lack of concern towards the stranded passengers. “If IAS officers don’t have humanity, what is the use of the IAS tag. Officers in the two states should learn to speak to one another and solve people’s problems,” he said apparently addressing DCs of Kasaragod and Dakshina Kannada. 

The 150 passengers had arrived on Saturday from Dubai in a chartered flight arranged by the Karnataka Cultural Foundation. The flight landed in Kannur after it was denied permission to land in Mangaluru.

But Karnataka’s nodal officer for stranded persons outside India C N Meena Nagaraj, an IAS officer, called up Kerala officials and questioned why the flight was allowed to land in Kannur, Khader said. She reportedly told Kerala officials that the passengers should be quarantined in the cities of arrival and that Karnataka would not take them in.

In the meantime, the Karnataka Cultural Foundation arranged seven buses to take the passengers to Mangaluru. By the time it was conveyed to them that they would not be allowed to enter Mangaluru, the buses had reached Kasaragod district. The representatives of the organisation made frantic calls to several political leaders. Congress leader and district panchayat standing committee chairperson Harshad Vorkady said he got a call for help around 10pm on Saturday. He spoke to owners of three lodges to accommodate them. The lodges were used by the district administration as quarantine centres. 

The lodge owners said they would take the passengers in only if the Kasaragod tahsildar gave permission. “So I called up the tahsildar. He only wanted to know who will pay for the lodging and food. When I told him that the passengers will pay, he gave permission. By midnight, all the passengers were put up in the three lodges,” he said. The police were also at the spot, he said.

According to the Covid protocol, those arriving from abroad should be in institutional quarantine for seven days and in room quarantine for another seven days. But by 4pm on Sunday, the police returned to the lodges and asked the passengers to vacate. They said it was the order of the collector. They produced the order to the lodge owners. The office-bearers of the Karnataka Cultural Foundation said they sought time from the Kasaragod police to arrange rooms in Mangaluru. But Kasaragod police denied it. 

On Sunday, there were Covid deaths in Mangaluru and the Mangaluru deputy commissioner was tied up as residents were objecting to the funeral of one of the victims. “By night, the police started threatening the lodge owners. The members of the Foundation said they would shift the passengers by Monday morning. But the collector would not listen,” said Harshad.

Around 11pm, the Kasaragod district administration brought in four KSRTC buses and sent all the 150 passengers to Mangaluru, he said. By 1am the buses crossed the Thalapdy border and Khader took over from there. But the MLA was livid with how officials treated the people. Collector Sajith Babu in a statement said his enquiry found that the tahsildar did not give permission to accommodate the passengers in Kasaragod lodges.
