Introduction:
Coronavirus illness is caused by the SARS-CoV-2 virus (COVID-19). The majority of people who are infected with the virus will experience mild to moderate respiratory symptoms and will recover without needing any treatment [1].
Fever, sore throat, cough, shortness of breath, diarrhea, and widespread weariness are the most prevalent symptoms. Acute distress respiratory syndrome, myocarditis, heart failure, renal failure, and recurrent pulmonary embolism are all complications of COVID-19 [2].
The neurological symptoms of COVID-19 infection include convulsions, paraplegia, hemiplegia, Guillain-Barre syndrome, transverse myelitis, and multiple cranial nerve involvement [3]. Lower motor neuron lesion facial palsy is referred to as Bell’s palsy in clinical terms. It is usually idiopathic; however tumors, trauma, infection, autoimmune illnesses, vacuities, pregnancy, and medicines can all cause it. Sarcoidosis, Guillain-Barre syndrome, and leprosy all have clinical symptoms that include bilateral facial palsy [4]. During the COVID-19 pandemic, there was a documented link between COVID-19 and Bell’s palsy. There is no clear explanation at this time; however it could be caused by a direct action of the virus, an autoimmune response, or recurrence of a coexisting herpes zoster infection [5].
In numerous nations, including the United States, a relationship between COVID-19 vaccines and lower motor neuron lesion facial palsy has been observed, albeit the causative link has yet to be proved [6].
