Long-term neurologic and psychomotor sequelae after neonatal tetanus

Three cases of neonatal tetanus in Papua New Guinea lead to development of national action plan for maternal and neonatal tetanus elimination

Maternal or neonatal tetanus causes deaths primarily in Asia and Africa and is usually the result of poor hygiene during delivery. In 2011, three neonatal tetanus cases were investigated in Papua New Guinea, and all three cases were delivered at home by untrained assistants. The babies were normal at birth but subsequently developed spasms. A neonatal tetanus case must be viewed as a sentinel event indicating a failure of public health services including immunization, antenatal care and delivery care. The confirmation of these cases led to the drafting of the Papua New Guinea National Action Plan for Maternal and Neonatal Tetanus Elimination. This included three rounds of a tetanus toxoid supplementary immunization campaign targeting women of childbearing age (WBCA) and strengthening of other clean delivery practices. The first immunization round was conducted in April and May 2012, targeting 1.6 million WBCA and achieved coverage of 77%. The government of Papua New Guinea should ensure detailed investigation of all neonatal tetanus cases reported in the health information system and perform subprovincial analysis of tetanus toxoid coverage following completion of all three immunization rounds. Efforts also should be made to strengthen clean delivery practices to help eliminate maternal and neonatal tetanus in Papua New Guinea.

Maternal and neonatal tetanus

Maternal and neonatal tetanus are important causes of maternal and neonatal mortality, claiming about 180 000 lives worldwide every year, almost exclusively in developing countries. Although easily prevented by maternal immunisation with tetanus toxoid vaccine, and aseptic obstetric and postnatal umbilical-cord care practices, maternal and neonatal tetanus persist as public-health problems in 48 countries, mainly in Asia and Africa. Survival of tetanus patients has improved substantially for those treated in hospitals with modern intensive-care facilities; however, such facilities are often unavailable where the tetanus burden is highest. The Maternal and Neonatal Tetanus Elimination Initiative assists countries in which maternal and neonatal tetanus has not been eliminated to provide immunisation with tetanus toxoid to women of childbearing age. The ultimate goal of this initiative is the worldwide elimination of maternal and neonatal tetanus. Since tetanus spores cannot be removed from the environment, sustaining elimination will require improvements to presently inadequate immunisation and health-service infrastructures, and universal access to those services. The renewed worldwide commitment to the reduction of maternal and child mortality, if translated into effective action, could help to provide the systemic changes needed for long-term elimination of maternal and neonatal tetanus.
