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, Apr 20: Dakshina Kannada police have warned of stringent legal action against people who share photos of the coronavirus victims in the district and other patients on social websites.

District superintendent of police B M Laxmi Prasad in a release, warned the people that strict legal action will be taken against those who flout rules.

Police have noted that a picture of one of the COVID-19 victims in the area is being shared on social media.

Providing any information about coronavirus-infected patients or victims publicly is a punishable offence, he said.

The police are putting together information about the people who shared the photo and other information about the COVID-19 in the district and have initiated legal action.

A 50-year old woman from Bantwal had died of Covid-19 at the Wenlock hospital here on Sunday.

She is the first coronavirus victim in the district.

Newsroom, Apr 22: Dozens of Tablighi Jamaat members from across the country who have been successfully recovered and have now tested negative for the novel coronavirus have come forward and donate their plasma for the treatment of Covid-19 patients.

The Tablighis from Tamil Nadu were the first to take this decision. According to them, apart from helping the critically ill patients to recover from COVID-19, was to counter the ‘baseless accusations’ that Tablighis were responsible for the spread of the virus following the religious congregation of the sect held at Delhi’s Nizamuddin area last month.

Mohammad Abbas, a thirty-eight year old businessman from Tiruppur was on Sunday discharged from Coimbatore’s ESI hospital. “As soon as I got discharged, I met the district administration officials and the dean of the hospital and told them that they may contact me anytime if they needed me to donate my plasma,” Abbas was quoted as saying by an English daily.

“It has only been one day since I was discharged but I’ve already spoken to others (from the Jamaat) who have recovered and they were all ready to donate,” he added. 

Leader's call

Maulana Saad Kandhalvi, a prominent leader of Tablighi Jamaat, who has been booked by the Delhi Police for holding a religious congregation, too has appealed to coronavirus survivors to donate blood plasma for infected people.

In a letter issued on Tuesday, Saad said most of the members who were quarantined did not have any infection and they tested negative for COVID-19.

"Even from amongst the ones who tested positive for the disease, a majority of them have now undergone treatment and are now cured while I and a few others are still under quarantine.

"It is required that such people who are now cured of this disease should donate blood plasma to others who are still fighting the disease and are under treatment," he said.

He also has urged the followers of the organisation to pray at home in the month of Ramadan instead of going to mosques. 

Plasma therapy

Convalescent Plasma Therapy is an experimental procedure for COVID-19 patients.

In this therapy, the antibodies of a person who has recovered from the virus are taken and transfused into a sick person (having the virus) to help boost the person’s immune system.

The recovered COVID-19 patient’s blood develops antibodies to battle against COVID-19.

Once the blood of the first patient is infused to the second patient, those antibodies will start fighting against the coronavirus in the second person.

The process for donating plasma is similar to donating blood and takes about an hour.

Several countries around the world including the United Kingdom and the United States have also started plasma therapy trials.

In India, several states like Kerala, Gujarat and Punjab have already started using Plasma Therapy for the corona-infected patients.
