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.

Thiruvananthapuram, Feb 9: Kerala has sanctioned the setting up of 28 fast track courts for speedy trial in rape cases and other cases registered under the Protection of Children from Sexual Offences (POCSO) Act.

State Social Justice and Women and Child Development Minister KK Shailaja said the state government has decided to set up POCSO courts to ensure that the culprits get the punishment they deserve. She said the decision has been taken in the wake of rising violence against women and children.

"The Union Law Ministry has recently sanctioned the opening of 28 POCSO fast track special courts in Kerala at the request of the state government. The project will be implemented jointly by the High Court, Law and Home Departments under the leadership of the Department of Women and Child Development," the Minister said.

The four courts are alloted in Thiruvananthapuram district, three in Thrissur and Malappuram districts, two each in Kollam, Kottayam, Idukki, Ernakulam, Palakkad, Kozhikode and Kannur districts.

The Minister informed that POCSO courts are jointly established by the central and state governments and according to the High Court data, 12,234 POCSO and rape cases are pending in the state.
