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].
