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, Jul 15: With the state capital along with a few districts under lockdown to control the spread of Covid-19, Karnataka Home Minister Basavaraj Bommai on Wednesday said the measure was important to break the chain and people seem to have understood its importance.

Appealing for cooperation from the people, he asked them not to make it inevitable for police to use force in implementing the lockdown. "Traffic movement is less, there is a lockdown atmosphere everywhere, I feel that people have understood the importance... cooperation is required. I appeal to the people, if this lockdown has to be effective it has to be voluntary, only then we can control the rapid spread of coronavirus," Bommai said.

Speaking to reporters here, he said this lockdown is important, last time the infection was not up to this level. "This time areas that have a high number of infections- about five districts and Bengaluru city are going for lockdown. People have understood that this lockdown is to break the chain," he said. "Please don't make it inevitable for police to use force," he added.

Bengaluru urban and rural areas are under "complete lockdown" since last night at 8 pm and it will be effective till 5 am on July 22.

Following Bengaluru urban and rural, administrations in several districts like Dharwad, Dakshina Kannada, Kalaburagi (only in Urban areas), Bidar, Raichur (in Raichur city and Sindhanur) and Yadgir too have announced lockdown.

Noting that Police have taken all necessary strict measures to enforce lockdown in Bengaluru urban and rural districts by restricting the movement of vehicles and people, Bommai said barricades have been erected at various places and flyovers have been shut. People have been allowed to purchase vegetables and groceries till 12 noon, he said.

The government has warned of action in case of any violation of the lockdown rules. As of July 14 evening, cumulatively 44,077 Covid-19 positive cases have been confirmed in the state, which includes 842 deaths and 17,390 discharges. Bengaluru Urban district tops the list of positive cases, with a total of 20,969 infections.

Bengaluru, May 22: Police commissioner Bhaskar Rao on Friday said the next two Sundays will be ‘full curfew days’ and the city will be under complete lockdown between 7pm Saturday and 7am Monday.

Addressing the media, the top cop said all essential services will be excluded from the curfew. “People attending weddings and other ceremonies can travel. Those wanting to buy food products or medicines too can step out. However, like in lockdown 1.0, people found loitering unnecessarily will be punished,” he said.

According to Rao, city roads will be barricaded like how it was done during lockdown 1.0 and 2.0.

A senior police officer told TOI that during this period, vehicles could be seized under the Disaster Management Act-2005. “So, we request the public not to come out unnecessarily. If we find people roaming in vehicles, we shall seize the rides and owners will have to approach the court later to get them released,” he said.

The government has extended the lockdown till May 31, which includes two Sundays.
Earlier in the day, the state government allowed inter-state travel from Karnataka with the consent of the receiving state. Praveen Sood, Karnataka DG and IGP, said, “Inter-state pass is not required to go out of Karnataka as long as you have the consent of the receiving state. Due to the lockdown, migrant workers, pilgrims, tourists, students and other persons are stranded at different places. They would be allowed to move as usual.”
