title: Poliomyelitis, measles and neonatal tetanus: a hospital based epidemiological study.
abstract: Vaccine-preventable diseases constitute a major health problem contributing to the morbidity and mortality in many developing countries including Egypt. WHO adopted resolutions to eradicate poliomyelitis by the year 2000, eliminate neonatal tetanus by the year 1995, and reduce measles mortality by 95% and morbidity by 90%, compared to the pre-immunization levels by 1995. Evaluation of preventive programs for these diseases necessitates availability of up to date information on their occurrence. The present study was undertaken to determine the current epidemiological features of poliomyelitis, neonatal tetanus and measles, to identify the trends of these diseases as well as to determine their outcomes and hospital loads. Data about the admitted cases of poliomyelitis, neonatal tetanus and measles were collected from the hospital register of Alexandria fever hospital for five successive years (1992-96). Available information on age, sex, residence, diagnosis, outcome of treatment, dates of admission and discharge were collected. The total number of cases of the three diseases admitted to the hospital during the period 1992-96 were 1406, measles represented 85.4%, neonatal tetanus 13.9% and poliomyelitis 0.7%. The results revealed that in the year 1994 only one case of poliomyelitis was admitted and since then no other cases were reported. The number of measles cases increased gradually in the latter years and about 78% of them were older than five years of age. A significant increase in the age of measles occurrence was observed. A gradual decline in the number of neonatal tetanus cases was observed. These cases were more apt to occur among early neonates but still clustered in certain geographical areas. The results of the study pinpoint the long term impact of the well run program aiming at eradicating poliomyelitis in Alexandria. However, for elimination of neonatal tetanus and controlling measles morbidity, further activities are required including strengthening the surveillance activities for detection of the high risk geographical areas and the high risk factors.
