Polyneuritis cranialis literally means inflammation of the cranial nerves. It is a rare neurological disorder characterised by multiple cranial nerve palsies sparing the spinal cord.[1]

Treatment

Medical Therapy

Surgery

Surgical intervention is not recommended for the management of COVID-19-associated polyneuritis cranialis.

Primary Prevention

  • The disease itself is associated with COVID-19 infection as believed to be an immune response so prevention of the infection itself is the most promising primary prevention strategy at the moment.
  • There have been rigorous efforts in order to develop a vaccine for novel coronavirus and several vaccines are in the later phases of trials.[7]
  • The only prevention for COVID-19 associated abdominal pain is the prevention and early diagnosis of the coronavirus-19 infection itself. According to the CDC, the measures include:[8]
    • Frequent handwashing with soap and water for at least 20 seconds or using a alcohol based hand sanitizer with at least 60% alcohol.
    • Staying at least 6 feet (about 2 arms’ length) from other people who do not live with you.
    • Covering your mouth and nose with a cloth face cover when around others and covering sneezes and coughs.
    • Cleaning and disinfecting.
