While discovering more about this novel Covid-19 pandemic,researchers find that it will result in loss of sense of smell,a clue of coronavirus. Doctor groups are recommending testing and isolation for people who lose their ability to smell may be a symptom of COVID-19, the disease caused by the coronavirus SARS-CoV-2. Specialists in the UK have suggested the loss of smell, also called anosmia, could even be an early indication of infection.
Viruses and bacteria are constantly bombarding the lining of the nose. Luckily our defence mechanisms prevent most pathogens penetrating into the deeper layers of tissue.It is noted that yet some pathogens can penetrate the nasal lining and are known to enter the olfactory nerve, which is responsible for the sense of smell.
Pathogens can also enter the trigeminal nerve, which is responsible for controlling biting and chewing, and for sensation in the face.We all have to try our best to follow precautions to avoid coronavirus as no vaccine yet discovered .
