Update on Wild Poliovirus Type 1 Outbreak - Southeastern Africa, 2021-2022.

Since the Global Polio Eradication Initiative (GPEI) began in 1988, the number of wild poliovirus (WPV) cases has declined by >99.99%. Five of the six World Health Organization (WHO) regions have been certified free of indigenous WPV, and WPV serotypes 2 and 3 have been declared eradicated globally (1). WPV type 1 (WPV1) remains endemic only in Afghanistan and Pakistan (2,3). Before the outbreak described in this report, WPV1 had not been detected in southeastern Africa since the 1990s, and on August 25, 2020, the WHO African Region was certified free of indigenous WPV (4). On February 16, 2022, WPV1 infection was confirmed in one child living in Malawi, with onset of paralysis on November 19, 2021. Genomic sequence analysis of the isolated poliovirus indicated that it originated in Pakistan (5). Cases were subsequently identified in Mozambique. This report summarizes progress in the outbreak response since the initial report (5). During November 2021-December 2022, nine children and adolescents with paralytic polio caused by WPV1 were identified in southeastern Africa: one in Malawi and eight in Mozambique. Malawi, Mozambique, and three neighboring countries at high risk for WPV1 importation (Tanzania, Zambia, and Zimbabwe) responded by increasing surveillance and organizing up to six rounds of national and subnational polio supplementary immunization activities (SIAs).* Although no cases of paralytic WPV1 infection have been reported in Malawi since November 2021 or in Mozambique since August 2022, undetected transmission might be ongoing because of poliovirus surveillance gaps and testing delays. Efforts to further enhance poliovirus surveillance sensitivity, improve SIA quality, and strengthen routine immunization are needed to ensure that WPV1 transmission has been interrupted within 12 months of the first case, thereby preserving the WHO African Region's WPV-free status.

Dual Bacillus Calmette-Guerin vaccination along the border communities of Angola and Namibia.

Without a doubt, the synchronization of public health intervention on health issues along the international border will enhance the control of epidemic-prone disease and other health-related behavior. However, the lack of holistic planning and the involvement of the members of border communities could result in undesired health related events. This report advanced reasons that could have resulted in a child receiving two separate doses of Bacillus Calmette-Guerin vaccine within the first 4 days of life in two different health facilities. Finally, this report highlighted the need for proactive community participation and the need for consensus by experts on guidelines on how to deal with such cases particularly in the unfortunate event of adverse reactions.

Maternal Mortality in the Main Referral Hospital in Angola, 2010-2014: Understanding the Context for Maternal Deaths Amidst Poor Documentation.

BACKGROUND: Increasing global health efforts have focused on preventing pregnancy-related maternal deaths, but the factors that contribute to maternal deaths in specific high-burden nations are poorly understood. The aim of this study was to identify factors that influence the occurrence of maternal deaths in a regional maternity hospital in Kuando Kubango province of Angola. METHODS: The study was a retrospective cross-sectional analysis of case notes of all maternal deaths and deliveries that were recorded from 2010 to 2014. The information collected included data on pregnancy, labor and post-natal period retrieved from case notes and the delivery register. RESULTS: During the period under study, a total of 7,158 live births were conducted out of which 131 resulted in maternal death with an overall maternal mortality ratio of 1,830 per 100,000 live births. The causes of death and their importance was relatively similar over the period reviewed. The direct obstetric causes accounted for 51% of all deaths. The major causes were hemorrhage (15%), puerperal sepsis (13%), eclampsia (11%) and ruptured uterus (10%). In addition, indirect non-obstetric medical causes such as Malaria, Anemia, hepatitis, AIDs and cardiovascular diseases accounted for 49% of all maternal deaths. There is poor documentation of personal data and clinical case management of cases. The factors of mutual instability of statistical significance associated with maternal death are: place of domicile (P=0.0001) and distance to the hospital (P=0.0001). CONCLUSION AND GLOBAL HEALTH IMPLICATION: The study demonstrated that the MMR in maternity hospital is very high and is higher than the WHO 2014 estimates and the province is yet to achieve the desired MDG 5 target by the end of 2015. A reversal of the present state requires data driven planning in order to improve access and use of Maternal Health Services (MHS) and ultimately lower the number of pregnancy-related maternal deaths.
