A guide to monitoring and evaluation for collaborative TB/HIV activities
Kanchar, A.; H.Getahun; P. Glaziou; et al.
World Health Organization (WHO); PEPFAR; UNAIDS; et al.
(2015)
C_WHO
Monitoring of implementation of collaborative TB/HIV activities and evaluation of impact is critically important. This requires efficient monitoring and evaluation system so as to establish accountability mechanisms between programmes, the populatio

n they serve, and donors. The Guide to monitoring and evaluation for collaborative TB/HIV activities will facilitate this process. The first version of the guide was developed in 2004 placing collaborative TB/HIV activities as integral part of national TB/HIV response. It was revised in 2009 to harmonize the approaches and indicators for monitoring and evaluation across key stakeholders. The current revision builds upon remarkable progress in implementation of collaborative TB/HIV activities and aims to strengthen the implementation further through improved quality of data.

Avec l’essor des traitements antirétroviraux (TAR) à base de dolutégravir (DTG) pour soigner les personnes vivant avec le VIH dans le monde, il est important d’estimer la vitesse à laquelle la résistance acquise au DTG apparaît dans les populations sous TAR. Bien que la résistance au DTG

The emergence of SARS-CoV-2 has significantly altered the epidemiology of other infectious diseases, making investigations into its co-infection with malaria particularly relevant in endemic regions. This review examines the epidemiological, incubation and clinical features of the two diseases, high

lighting the diagnostic challenges and strategies for accurate detection. Emerging immunological and genetic evidence indicates that prior exposure to malaria may reduce the severity of outcomes of SARS-CoV-2 infection through mechanisms involving ACE2 downregulation, TLR signalling, T-cell activation and upregulation of coinhibitory receptors. Additionally, potential control measures are discussed, including vaccine development, the repurposing of antimalarial drugs, the exploration of natural products, innovations in bioinsecticides, and the strengthening of electronic disease surveillance. These insights provide valuable guidance for clinical management and public health policy, while emphasising the need for continued research into the complex interactions between SARS-CoV-2 and malaria.

Public Health Risk Analysis and Surveillance
Public Health Surveillance Protocol Tuberculosis
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 miscl
...
assification 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.
