The Zimbabwe National Pharmacovigilance Policy Handbook, 2nd Edition updates the November 2013 version to indicate the Zimbabwe National Pharmacovigilance (PV) Centre’s compliance with the WHO Pharmacovigilance Indicators Handbook 2015.
This report investigates the impact of potential misclassification of samples on HIV prevalence estimates for 23 surveys conducted from 2010-2014. In addition to visual inspection of laboratory results, we examined how accounting for potential misclassification of HIV status through Bayesian latent ...class models affected the prevalence estimates. Two types of Bayesian models were specified: a model that only uses the individual dichotomous test results and a continuous model that uses the quantitative information of the EIA (i.e., the signal-to-cutoff values). Overall, we found that adjusted prevalence estimates matched the surveys’ original results, with overlapping uncertainty intervals. This suggested that misclassification of HIV status should not affect the prevalence estimates in most surveys. However, our analyses suggested that two surveys may be problematic. The prevalence could have been overestimated in the Uganda AIDS Indicator Survey 2011 and the Zambia Demographic and Health Survey 2013-14, although the magnitude of overestimation remains difficult to ascertain. Interpreting results from the Uganda survey is difficult because of the lack of internal quality control and potential violation of the multivariate normality assumption of the continuous Bayesian latent class model. In conclusion, despite the limitations of our latent class models, our analyses suggest that prevalence estimates from most of the surveys reviewed are not affected by sample misclassification.

This guidance addresses rationale, risk-based scenarios, practical considerations prior to adoption of the self-testing products, quality assurance, safety and ethical considerations, and data management considerations for COVID-19 self-testing. The Africa CDC recommends the use of rapid antigen sel...f-testing within two key scenarios. The first includes testing for case identification within scenarios with a high risk of infection, including symptomatic cases and contacts of a confirmed case. The second scenario involves general screening within scenarios of low or unknown risk exposure allowing for self-care such as before gatherings with at-risk individuals and prior to participation in events involving members of different households. Within these scenarios, a positive test result indicates likelihood of current infection, while a negative test result indicates a lower risk of active infection, though it does not rule out infection altogether. All positive cases should be managed following the national COVID-19 management protocol of Member States.ssur

This document provides countries with recommendations for structuring a public health entomology laboratory network. The document will help countries to identify their areas of need and determine how the entomology network can be strengthened, especially in the context of a decentralized health syst...em. The recommendations also consider the different degrees of development and different entomological research needed to support disease prevention and control activities.

External quality assessment (EQA) is an important component of quality systems for blood transfusion services. Establishing external quality assessment programmes for screening of donated blood for transfusion-transmissible infections (TTI): implementation guide aims to support WHO member States in ...establishing and operating EQA programmes for screening donated blood for TTI. The guides has been designed for use by national health authorities and EQA organizing institutions in the development of EQA programme. It will also give participating laboratories an insight into the organization of EQA programmes for TTI screening and an understanding of the benefits of participation.

According to the Report, cascading and interlinked crises are putting the 2030 Agenda for Sustainable Development in grave danger, along with humanity’s very own survival. The Report highlights the severity and magnitude of the challenges before us. The confluence of crises, dominated by COVID-19,... climate change, and conflicts, are creating spin-off impacts on food and nutrition, health, education, the environment, and peace and security, and affecting all the Sustainable Development Goals (SDGs). The Report details the reversal of years of progress in eradicating poverty and hunger, improving health and education, providing basic services, and much more. It also points out areas that need urgent action in order to rescue the SDGs and deliver meaningful progress for people and the planet by 2030.

The household transmission investigation is a case-ascertained prospective study of all identified household contacts of a laboratory confirmed 2019-nCoV infection (see 2.2 Study population). It is intended to provide rapid and early information on the clinical, epidemiological and virological chara...cteristics of 2019-nCoV.
There are three primary objectives of this household transmission study:
To better understand the extent of transmission within a household by estimating the secondary infection rate for household contacts at an individual level, and factors associated with any variation in the secondary infection risk.
To characterize secondary cases including the range of clinical presentation, risk factors for infection, and the extent and fraction of asymptomatic infections.
To characterize serologic response following confirmed 2019-nCoV infection (highly encouraged, but optional depending on laboratory capacity and resources)
