Scientists confirm smell and taste loss as early signs of COVID-19

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: Following reports of fresh Nipah virus (NiV) cases in West Bengal and heightened vigilance across parts of Southeast Asia, the Karnataka Health Department has placed the state on high alert and activated emergency preparedness protocols.

Health officials said enhanced surveillance measures have been initiated after two healthcare workers in Barasat, West Bengal, tested positive for the virus earlier this month. While no cases have been reported in Karnataka so far, authorities said the state’s past exposure to Nipah outbreaks and high inter-state mobility warranted preventive action.

Officials have directed district health teams to intensify monitoring, particularly at hospitals and points of entry, and to ensure early detection and isolation of suspected cases.

High Mortality Virus with Multiple Transmission Routes

Nipah virus is a zoonotic disease that can spread from animals to humans and has a reported fatality rate ranging between 60 and 75 per cent. Fruit bats, also known as flying foxes, are the natural reservoirs of the virus and can transmit it by contaminating food sources with saliva or urine.

Known modes of transmission include:

•    Contaminated food: Consumption of fruits partially eaten by bats or raw date-palm sap
•    Animal contact: Exposure to infected pigs or other animals
•    Human-to-human transmission: Close contact with body fluids of infected persons, particularly in healthcare settings

Symptoms and Disease Progression

The incubation period typically ranges from 4 to 14 days, though delayed onset has also been reported. Early symptoms often resemble common viral infections, making prompt clinical suspicion critical.

•    Initial symptoms: Fever, headache, body aches, fatigue, sore throat
•    Progressive symptoms: Drowsiness, disorientation, altered mental state
•    Severe stage: Seizures, neck stiffness and acute encephalitis, which can rapidly progress to coma

Public Health Advisory

The Health Department has issued precautionary guidelines urging the public to adopt risk-avoidance practices to prevent any local spillover.

Do’s
•    Wash fruits thoroughly before consumption
•    Drink boiled and cooled water
•    Use protective equipment while handling livestock
•    Maintain strict hand hygiene

Don’ts
•    Avoid fruits found on the ground or showing bite marks
•    Do not consume beverages made from raw tree sap, including toddy
•    Avoid areas with dense bat populations
•    Do not handle sick or dead animals

Preparedness Measures

Officials confirmed that isolation wards are being readied in major government hospitals and that medical staff are being sensitised to identify early warning signs.

“There is no cause for panic, but there is a need for heightened vigilance,” a senior health official said, adding that there is currently no approved vaccine or specific antiviral treatment for Nipah, and care remains largely supportive.

The coastal city of Mangaluru is gearing up for a major sporting milestone with the launch of a Golf Excellence Academy at the Pilikula Golf Club (PGC), scheduled to open on May 31. The initiative aims to position Mangaluru firmly on India’s national golfing map.

Speaking to reporters on Saturday during PGC’s first-ever floodlit Pro-Am tournament, club captain Manoj Kumar Shetty said the project is being funded by UAE-based philanthropist Michael D’Souza and is currently in the design phase. Experts from leading golf academies across the country are expected to visit Mangaluru to help shape the training programme and infrastructure.

The academy will train 20 young golfers at a time, with a long-term vision of producing national-level players from the region. Until now, PGC relied on an in-house coach, but the recent renovation of the course and the introduction of floodlights have opened new possibilities for expanding the sport.

Shetty said discussions are underway with two reputed coaching academies, whose heads are expected to visit PGC shortly. “A dormitory for trainers is already under construction. We are inviting academies to assess the facilities and suggest changes so we can build a truly world-class Golf Excellence Academy,” he said.

Professional golfer Aryan Roopa Anand noted that the floodlit course would be a game-changer for young players. “Students can now practise after school hours, even up to 8 or 9 pm, without compromising on academics,” he said.

In an era where digital distractions are the primary rival to academic excellence, the Karnataka Education Department is taking the fight directly to the living room. As the SSLC (Class 10) annual examinations loom, officials have launched a localized "digital strike" to ensure students aren't losing their competitive edge to scrolling or soap operas.

The 7-to-9 Lockdown

The department has issued a formal directive urging—and in some cases, enforcing via home visits—a total blackout of mobile phones and television sets between 7:00 PM and 9:00 PM. This two-hour window is being designated as "sacred study time" across the state until the examinations conclude on April 2.

Key Pillars of the Initiative:

•    Doorstep Advocacy: Teachers are transitioning from classrooms to living rooms, meeting parents to explain the psychological benefits of a distraction-free environment.

•    Parental Accountability: The campaign shifts the burden of discipline from the student to the household, asking parents to lead by example and switch off their own devices.

•    The Timeline: The focus remains sharp on the upcoming exam block, scheduled from March 18 to April 2.

"The objective is simple: uninterrupted focus. We are reclaiming the evening hours for the students, ensuring their environment is as prepared as their minds," stated a senior department official.

Student vs. Reality

While the student community has largely welcomed the "forced focus"—with many admitting they lack the willpower to ignore notifications—the move has sparked a debate on enforceability. Without a "TV Police," the success of this initiative rests entirely on the shoulders of parents and the persuasive power of visiting educators.
