After conducting the study, the researchers concluded that people infected with the coronavirus could not recognize the smell of peppermint and coconut oil.
When the coronavirus appeared and began to spread, a dry cough and fever were considered its main symptoms, but recent research has shown that loss of smell and taste are the main indicators of infection.
Many scientists believe that anosmia or loss of smell is an early warning sign of coronavirus infection, but researchers in India have shown that people infected with coronavirus do not just smell certain things.
Indian scientists have used five different flavors, common to every Indian household, and developed an “odor test”. The scents they chose for the test, using an online survey, were garlic, peppermint, cardamom, coconut oil and fennel, writes the Times of India.
The study was performed on 49 asymptomatic patients and 35 non-infected individuals. They were asked to test five flavors and see if they could smell and recognize them. According to the report, a second experiment was performed as a check, in which the order of the scents was changed and water was added to the test.
Only 4.1 percent of respondents failed to recognize any odor, 38.8 percent could not identify one of the odors, and 16 percent could not identify two. Healthy study participants could smell all the aromas, but 14 percent of them failed to accurately recognize at least one scent.
After conducting the study, the researchers concluded that people infected with the coronavirus could not recognize the smell of peppermint and coconut oil. Although further research is needed, they believe that such an odor test may help identify asymptomatic patients.
