One of the biggest concerns about the progression of coronavirus pandemic is the possibility of infection by people who have no symptoms and can transmit the virus.
In response, the U.S. military in South Korea began using simple evidence of one of the lesser-known effects of Covid-19. Without measuring the temperature or asking the person about the family member’s travel history or health condition, military personnel from Daegu in South Korea are conducting a “vinegar test”.
At the entrance to the complex, security guards stop any visitor and offer him a piece of cotton dipped in vinegar. As they explained on their social networks, “the main symptom for 30% of patients with mild cases is wind loss (or anosmia), according to recent studies, and 66% of Covid-19 patients suffer from anosmia.” A spokesman for U.S. forces stationed in South Korea told Newsweek that the proceedings began Friday at various entry points.
Lack of smell is a recently established symptom. Doctors discovered many cases of people who only had this symptom without any other symptoms. The SARS CoV-2 virus when it enters the nose, instead of attacking the mucosa like other viruses, attacks the olfactory nerve and blocks the aroma molecules. “There is a clear link between anosmia and the virus,” said Jean-Michel Klein, president of the ENT National Professional Council, based in Paris.
