Guillain-Barré syndrome (GBS) is a lower motor neuron disease due to postinflammatory immunological reaction leading to demyelination. Usual preceding etiologies are acute viral episodes caused by cytomegalovirus, Epstein-Barr, and Zika infections, among others. Bacterial organisms causing GBS are Mycoplasma pneumonia, Campylobacter jejuni, Haemophilus influenzae, and Shigella. It can also occur postimmunization against rabies, influenza, MMR (measles, mumps, rubella) and conjugated meningococcal vaccine. A rare case of GBS (acute inflammatory demyelinating polyneuropathy) occurring after an episode of leptospirosis infection is presented.
