COVID-19 Scent Test Strips - Smell test 27 times for effective than temperature check

Studies show that loss of smell is a more effective indicator of COVID-19 than a temperature check.  A study with 2,8618,862 participants concluded: 

"Our work suggests that loss of sense of smell and taste could be included as part of routine screening for COVID-19 and should be added to the symptom list currently developed by the World Health Organization".  Published in Nature Medicine.

Pontificil Catholic University in Chili is one of a growing number of organizations that have developed a scent test kit that could be a better indicator of COVID-19.


The loss of smell is one of the earliest symptoms of the virus and for many people, it's the only thing they experience. A Mayo Clinic study found that people who have COVID-19 are 27 times more likely than others to lose their sense of smell and taste, but they were only two times more likely to have a fever than those without coronavirus. 

Experts say workplaces and schools should adapt their screening methods as a result of this study. They recommend using some form of scratch and sniff or scent testing to help identify potential cases of COVID-19. - WCNC Charlotte.  


In a recent study of 1,480 patients led by otolaryngologist Carol Yan of UC San Diego Health, someone with anosmia was “more than 10 times more likely to have COVID-19 than other causes of infection,” she said. Nasal inflammation from some 200 cold, flu, and other viruses can cause it, she said, but especially during the summer, when those infections are pretty rare, the chance that anosmia is the result of COVID-19 rises.

Recent studies suggest that a loss of smell may be a symptom of COVID-19. As a result, USAG also cited a guidance document from ENT UK, the British Association of Otorhinolaryngology, that found COVID-19 patients in countries including South Korea often had a more difficult time smelling.

For example, the guidance said that for 30 percent of patients with mild cases of COVID-19, their primary symptom was a loss of smell, known as anosmia. The guidance also reported that more than 66 percent of COVID-19 patients in Germany suffered from anosmia. - The Army Times

Tests are still being created.  Some are using scratch and sniff cards while others are using the ability to smell common strong smells, such as apple cider vinegar. 


Tests will continue to evolve, but as of this writing having the person smell two scent test strips, one with the fragrance (apple cider vinegar is inexpensive and works) and one with no scent, and ask them to identify which one smells is the quickest and easiest test.
