Jewellery worth Rs 11 lakh stolen from car at Panambur beach

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.

New Delhi, Apr 16: Minority Affairs Minister Mukhtar Abbas Naqvi on Thursday directed state waqf boards to ensure strict implementation of lockdown and social distancing guidelines during the holy month of Ramzan starting next week amid the coronavirus pandemic.

At a meeting via video conferencing, Naqvi asked the state waqf boards' officials to create awareness among people to offer prayers and perform other religious rituals like "iftar (breaking of fast)" during Ramzan, which begins on April 24 or 25, staying inside their homes.

More than seven lakh registered mosques, eidgahs, imambadas, dargahs and other religious and social institutions come under state waqf boards across the country. The Central Waqf Council is the regulatory body of state waqf boards in India.

"We should cooperate with health workers, security forces, administrative officers, sanitation workers. They are working for our safety and well-being even putting their own lives at risk in this coronavirus pandemic," Naqvi said.

"We should also demolish rumours and misinformation being spread about quarantine and isolation centres by creating awareness among people that such centres are only meant to protect people, their families and the society from the pandemic," the minister said.

Naqvi told all the state waqf boards and religious and social organisations that everyone should remain cautious of any type of fake news and conspiracies aimed at creating misinformation. 

"Authorities have been working for safety and well-being of all citizens of the country without any discrimination. Such type of rumours and conspiracies are a nefarious design to weaken the fight against coronavirus," he said.

"We should work united to win this fight against corona by defeating any type of rumour, misinformation and conspiracy," the minister said.

Naqvi asked officials of all the state waqf boards to play an active and effective role in ensuring that people follow the guidelines of the Union Home Ministry, state governments and the Central Waqf Council while fulfilling religious responsibilities during Ramzan.

In view of the challenges of the COVID-19 pandemic, all religious and social activities and mass gatherings in all the temples, gurdwaras, churches and other religious and social places of the country have been stopped, he said. 

Similarly, any mass gatherings in mosques and other Muslim religious places of the country has also been stopped, Naqvi said.

He said that due to the COVID-19 threat, religious leaders as well as religious and social organisations from all regions of the country, have appealed to people to offer prayers and perform all other religious rituals staying inside their homes during Ramzan. 

Most of the Muslim nations of the world have also banned mass gatherings at mosques and other religious places during the holy month, he pointed out.

Prime Minister Narendra Modi, in cooperation with all the state governments, has been working effectively for the safety and well-being of the people, he said.

The cooperation of the people has brought great relief to India in the war against COVID-19 Naqvi said, adding that several challenges are still there before the country. 

"We can defeat these challenges of the coronavirus pandemic by following all the guidelines of the central and state governments strictly," he asserted.

Chairman and senior officials from state waqf boards such as Uttar Pradesh (Shia & Sunni), Andhra Pradesh, Bihar (Shia & Sunni), Dadra & Nagar Haveli, Haryana, Karnataka, Kerala, Madhya Pradesh, Punjab, West Bengal, Andaman & Nicobar, Assam, Manipur, among others participated in the meeting.
