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.

Bengaluru, Jan 17: Karnataka Health Minister and BJP leader B Sriramulu on Friday claimed that Congress supports Social Democratic Party of India (SDPI) and Popular Front of India (PFI) to disturb peace in the state.

His statement came after the arrest of 6 SDPI supporters in connection with an attack on a BJP-RSS follower during a pro-CAA rally held in December last year.

"The Congress party 100 per cent supports SDPI and PFI. Whenever they do not get the power, they try to disturb the peace with the support of SDPI and PFI. I will propose in Karnataka Assembly session to ban these organisations in Karnataka. We will discuss this matter," Sriramulu told ANI.

"We had already demanded for the ban on these organisations in Karnataka when I was an MP. Shobha Karandlaje, Yediyurappa and I had met Rajnath Singh, the then Home Minister in Delhi and we had given a memorandum to ban SDPI and PFI," he added.

A case has been registered against arrested SDPI supporters under relevant Sections of the Indian Penal Code (IPC). Bengaluru Police is constituting a new Special Investigation Team (SIT) to handle this case.

"There were 6 people belonging to SDPI, who were here to carry out attacks on leaders supporting CAA. These people were being paid Rs 10,000 from their handlers to create ruckus here. Now this will be handled by the Anti-Terror unit," said Bhaskar Rao, Bengaluru Commissioner of Police.

Earlier today, Karnataka Minister Jagadish Shettar called for a ban on SDPI.

"SDPI always denies their involvement but it has been proved now. I welcome the police's action. Their organisation should be banned as they have always been involved in anti-social activities and government of India should take very serious note of this," Shettar told ANI here.
