As per a report published in ANI, the researchers conducted the survey on 10 coronavirus patients, 10 people with common cold and 10 healthy people with no symptoms of coronavirus or regular cold and flu. According to the study, some of the telltale differences in smell loss due to regular cold and COVID-19 include:
1. Coronavirus patients are able to breathe freely even with a loss of smell
2. They do not have a runny nose or blocked nose
3. They are not able to differentiate between bitter and sweet taste
The research further highlighted that the loss of smell and taste was more significant in coronavirus patients as they experienced ‘true loss of taste.’ The researchers speculate that the smell and taste disorders in COVID-19 patients could be caused by the impact of novel coronavirus on the brain and nervous system.
