Guillain-Barre syndrome (GBS), which is caused by a viral or bacterial infection, causes the immune system to attack the body, weakening muscles and progressively paralyzing different parts of the body. The World Health Organization (WHO) has detected 85 cases in the enclave since June. Three of these patients have died, according to the Hamas-run Gaza Ministry of Health. The WHO acknowledges that the cause of the disease is not fully understood, but it is being linked to contaminated food or the consumption of untreated water.
GBS is a condition where the body's immune system attacks the myelin sheath, which protects the peripheral nerves. This exposes the nerve fibre and causes nerve damage. Peripheral nerves branch out from the brain and spinal cord to all parts of the body, such as the skin, muscles and organs. GBS is a very rare condition, affecting about 100,000 people worldwide every year, according to the Cleveland Clinic's website.
