Background: Despite the Maternal and Neonatal Tetanus (MNT) elimination initiative, neonatal tetanus still persists in some parts of the world. Objectives: To determine hospital prevalence and describe epidemiological, clinical, therapeutic and outcome aspects of neonatal tetanus at the Pediatric Teaching Hospital in Bangui. Methodology: It was the review of hospitalized newborns' files in the neonatal unit at Pediatric Teaching Hospital in Bangui between January 2016 and December 2019. Newborns discharged with tetanus diagnosis, and whose files were usable were included. The variables studied were: for the newborn: age, sex, birth weight, the reason for transfer, diagnosis, cause and time of death, place and method of delivery; for the mother: age, antenatal care, tetanus vaccine status, parity and geographical provenance. Epi Info 7 software, version 7.1.3.3 was used for data analysis. The chi2 test with the significance level set at p < 0.05 and the odds ratio were used. Résultats: Forty-eight (48) out of 5796 newborns had neonatal tetanus (0.8%). They were newborns to mothers with an average age of 18.8 years of which 68.8% (n = 33) were primipara and 87.5% (n = 42) not vaccinated against tetanus. Childbirth happened at home in 91.7% (n = 44), and the blade was used for sectioning the umbilical cord in 39.6% (n = 19). Newborns were referred from rural area in 47.9% (n = 23). A single antenatal care contact was done in 68.7% (n = 33). Tetanus was classified as severe according to the Dakar prognosis score between 4 and 6 in 89.6% of cases (n = 43). The death occurred in 58.3% (n = 28). Conclusion: The high frequency of neonatal tetanus as well as its severity requires pregnancy follow-up strengthening and childbirth monitoring in order to its elimination.

Background: Rotavirus is the most common pathogen of severe acute diarrhea in children under five years of age worldwide. Objective: The objective of this study was to determine the morbidity and mortality of rotavirus diarrhea while describing the seasonal kinetics of the infection according to climatic parameters in Bangui. Methodology: This was a descriptive and analytical cross-sectional study conducted from January 1, 2011 to December 31, 2020 in the Central African Republic (CHUPB). The health data were recorded and processed with the Access 2019 software, then analyzed with the STATA version 14 software. The climatic trends in the study area and its seasonal variations were highlighted by the monthly rainfall coefficient of Alfred Angot: Cm = 12 Pm/P. Results: Morbidity was 45.99% of cases. The 1 to 12 months old represented 93.81% of cases. The mean age of the children was 6.8 months, the sex ratio was 1.20. The symptomatic triad was diarrhea (100%), vomiting (90.20%) and fever (87.5%). Moderate dehydration was reported in 81.05% of cases. The main genotype combinations found were P[8]G1 in 34.02% (n = 115/338), P[6]G1 in 21.59% (n = 73/338) and P[6]G2 in 16.86% (n = 57/338). Case fatality was 11.45%. The risk of death was influenced by rural origin, severe dehydration, hypovolemic cloc and duration of hospitalization > 5 days. Low rainfall correlated with the highest rates of rotavirus diarrhea. Likewise, high temperature correlated with the highest number of cases of rotavirus diarrhea. Conclusion: Acute rotavirus diarrhea is an important morbidity and mortality issue in children under 5 years old in Bangui.
