Tetanus can occur after an injury and is caused by the exotoxin of Clostridium tetani. Characteristics of generalised tetanus include spasms in the back and other muscles, trismus, risus sardonicus and difficulty in breathing caused by laryngospasms. Vaccination through the National Vaccination Programme of the Netherlands has resulted in 94% of the population being protected against tetanus; certain groups, however, have a low rate of vaccination. In the Netherlands, 5 patients were reported to have generalised tetanus in 2011. This figure is relatively high in comparison with previous years. Of these 5 patients, 3 did not receive post-exposure-prophylaxis (PEP) after their injuries, or received it incompletely. PEP may be comprised of 1 or more vaccinations with the tetanus toxoid and/or the administration of tetanus immunoglobulin. Patients who have sustained an injury should be evaluated in accordance with the guideline 'Tetanus' by the Landelijke Coördinatie Infectieziekten (National Coordination Centre for communicable disease control), and to assess whether PEP is indicated.
