This study found a relatively high incidence of severe rotavirus-associated diarrhea disease in Nigeria and infants were the most affected. It highlights the urgent need for introduction of rotavirus vaccine into the national immunization program and the need to adequately equip health facilities to enable them administer intravenous fluids to severe diarrhea patients to reduce morbidity and mortality.

Rotavirus gastroenteritis is a major public health concern globally, estimated to cause 215,000 deaths among children < 5 years of age in 2013; with majority of mortality occurring in developing countries. In 2013, it was estimated that Nigeria was the second country with the highest number of rotavirus deaths. Monitoring of circulating rotavirus strains in Enugu, Nigeria is part of ongoing rotavirus surveillance before the introduction of rotavirus vaccination. A total of 2694 stool samples were collected from enrolled under 5 years old children with diarrhoea between January 2011 and December 2016 and tested the virus using an antigen enzyme immunoassay. Randomly selected rotavirus positive samples were further characterized by rotavirus genotype methods to identify the G and P types circulating during the study period. Rotavirus was detected in 1242 (46%) of the 2694 samples collected over the six years period. Of these, 867 were randomly selected for genotyping. G and P types could be assigned for 832 samples (96%), while 31 (3.6%) could only #

124(15.6%) and abnormal/absent bowel sound 43 (15.9%). Diagnosis was essentially with the aid of abdominal ultrasonography, 38 (63.3%) while surgery (laparotomy) was the treatment of choice in most cases 48 (80.0%). The case fatality rate was 3 (5.0%). Conclusion: None of the cases studied could be directly linked to rotavirus vaccinations. But seasonal peak incidence coincided with rotavirus diarrhea peak incidence. Efforts should be made to institute post-rotavirus vaccine licensure prospective surveillance study in order to fully determine any relationship between rotavirus vaccination and intussusception in Enugu, South east, Nigeria.

Background: Breastfeeding is cost effective means towards the realization of some key United Nations Sustainable Development Goals by the year 2030 particularly in resource limited settings. The objectives of the study were to evaluate the predictors of exclusive breastfeeding duration among mother and child pairs utilizing a tertiary immunization clinic facility. Methods: This was a cross-sectional descriptive study. Respondents were mother-and-child pairs who were recruited consecutively. Relevant maternal and child characteristics were collected using a semi-structured questionnaire. Data were analyzed using Statistical Package for Social Sciences version 20.0 (p < 0.05). Results: Four hundred and twenty seven mother-child pairs were studied. Majority of the mothers have at least secondary education, 383 (80.7%). 407 (95.3%) of the mothers fully understood the actual meaning of EBF. 189 (42.7%) reported practicing EBF in their index child for six months. Maternal perception of insufficient milk production, 52/99 (52.5%) was the most common reason for practicing EBF for <6 months among respondents. Maternal education and occupation and gender of the child were significantly associated with completion of EBF for 6 months among respondents. Conclusion: EBF duration in the current study is low and is significantly associated with maternal education, maternal occupation and gender of the child. Improving girl child education, complementing baby friendly hospital initiative with baby friendly community initiative should be adopted to improve EBF duration in our setting.
