Among the most prominent symptoms of the Corona virus is a lack of the sense of smell or loss of smell, and the lack of the sense of smell is a partial loss of smell, as for the loss of the sense of smell, it is the complete loss of smell, along with the loss of the sense of smell, there is a loss of the sense of taste, fever, cough, headache, difficulty breathing, The number of cases rises globally, it is important to find easy, cost-effective and fast screening tests.
In the study, published on the medRxiv website, researchers developed a new tool to help discover Corona infection, as the team developed and tested a real-time tool to measure olfactory perceptual impairment by asking participants to smell household scents.
The Corona pandemic first appeared in Wuhan, China, in December 2019. Since then, the virus has spread to 192 countries and regions, infecting more than 112.22 million cases worldwide.
During the first few months of the pandemic, common signs and symptoms reported included fever, coughing and difficulty breathing, and when the virus spread to more people, other symptoms were reported, including loss of taste, loss of smell, diarrhea, headache, and body aches. Among other things.
It remains unclear how the Corona virus can cause a loss of smell, but some evidence has shown that it binds to a protein called angiotensin-converting enzyme 2 (ACE2), which is found in abundance in the nose and mouth.
The researchers developed an online tool in which each participant selected 5 of 71 home scents, smelled and classified each of them, and then the participants answered a common questionnaire to verify symptoms of Corona, in which they reported coughing, fever, loss of smell and loss of taste.
The researchers collected data from more than 12,000 participants from 134 countries, and of these, 348 participants reported positive test results for Corona tests.
The results of the study confirm that an olfactory test can be an excellent border-monitoring tool to distinguish between people who carry an infection.
