A recent study conducted by researchers from the National Agri-Food Biotechnology Institute Mohali and the Postgraduate Institute of Medical Education and Research Chandigarh on smell test, found that COVID-19 patients were unable to smell two scents - coconut oil and peppermint.
Earlier this year, researchers from University College London said that it may be a more reliable indicator that a person has the virus. Losing your sense of smell could be the most common Covid-19 symptom, the study had suggested.
"We observed that, only 6.1 per cent of Covid-19 individuals were not able to smell/identify all five odorants," the team wrote in their study. As many as 38.8 per cent were unable to smell at least one odorant, while 16 per cent were unable to smell two, the researchers said.
According to the research, only 4.1 per cent of the participants were not able to detect or smell any of the five odorants used in the study.
According to the research, of the 35 uninfected individuals in the study, all were able to smell the odorants, although 14 per cent misidentified at least one.
The study led the researchers to find that peppermint and coconut oil were the two scents most Covid-19 patients were unable to smell.
Nine in ten recovered COVID-19 patients experience side-effects, study shows
Nine in ten coronavirus patients reported experiencing side-effects such as fatigue, psychological after-effects and loss of smell and taste after they recovered from the disease, according to a preliminary study by South Korea.
The research comes as the global death toll from COVID-19 passed 1 million on Tuesday, a grim milestone in a pandemic that has devastated the global economy, overloaded health systems and changed the way people live.
In an online survey of 965 recovered COVID-19 patients, 879 people or 91.1% responded they were suffering at least one side-effect from the disease, the Korea Disease Control and Prevention Agency (KDCA) official Kwon Jun-wook told a briefing.
Fatigue was the most common side-effect with 26.2% reading, followed by difficulty in concentration which had 24.6%, Kwon said.
Other after-effects included psychological or mental side-effects and loss of taste or smell.
Kim Shin-woo, professor of internal medicine at Kyungpook National University School of Medicine in Daegu, sought comments from 5,762 recovered patients in South Korea and 16.7% of them participated in the survey, said Kwon.
While the research was done online for now, lead researcher Kim will soon publish the study with detailed analysis, he said.
South Korea is also conducting a separate study with some 16 medical organisations on potential complications of the disease through a detailed analysis involving CT scans on recovered patients next year, Kwon told the briefing.
The country reported 38 new infections by midnight on Monday, for a fifth day of double-digit increases, taking the national tally to 23,699 cases, with 407 deaths.
