In recent years, there has been a proliferation of new terms in relation to malaria in scientific literature, technical reports and the media. Concurrently, a number of terms with new or modified use and meaning have been introduced. This glossary of malaria terminology, updated in 2021, is based on input from WHO technical expert groups and aims to improve communication and mutual understanding within the scientific community, as well as with funding agencies, public health officials responsible for malaria programmes, and policymakers in malaria endemic countries.

This document is intended as a guide for studies of chemoprevention efficacy and was developed based on reviews of protocols of ongoing studies. The document adapts some of the principles and practices underlying treatment efficacy monitoring to provide standardized approaches for monitoring and evaluating the efficacy of medicines used for malaria chemoprevention. This guide will be updated once additional experience is gained from studies of chemoprevention efficacy.

This document provides extended guidance to countries that are nearing malaria elimination on preparing for certification. It includes an overview of the certification process and examines the activities required in national preparation for certification. It provides tools that countries can use to organize the documentation required for certification, to prepare a national elimination report and to assess their readiness for certification. Guidance on verification of subnational malaria elimination, a process overseen by national authorities, is also provided. This second edition clarifies the definition of human infections of Plasmodium knowlesi and its implications to certification and includes the template for national elimination report in Annex 4.

The meeting objectives included providing an overview of the current status of insecticide resistance and resistance management practices, as well as of the ways in which economic principles can be applied to value insecticide susceptibility. The main target audiences were National Malaria Control Programs, their implementing partner organizations and donors.

Indoor residual spraying (IRS) involves applying residual insecticide to potential vector resting sites on the interior surfaces of human dwellings or other buildings. The main aim of IRS is to kill vectors before they are able to transmit pathogens to humans. When carried out correctly, IRS has historically been shown to be a powerful intervention to reduce adult vector density and longevity for mosquitoes, sand flies and triatomine bugs and can reduce the transmission of vector-borne diseases. This operational manual is designed to provide guidance on the establishment, management, implementation, reporting and evaluation of safe and effective IRS campaigns within the context of a locally adapted and sustainable vector control programme, in line with the Global vector control response 2017–2030. It provides information according to current WHO recommendations and standards on IRS and recognizes that IRS can potentially target multiple diseases in areas where endophilic vectors coexist. The key audience for this document is vector-borne disease control programme managers and staff, as well as implementing or private-sector partners at the national, provincial/state or local levels, who are responsible for the design, planning or implementation of vector control operations.

Infectious diseases are the leading cause of death globally, particularly among children and young adults. The spread of new pathogens and the threat of antimicrobial resistance pose particular challenges in combating these diseases. Major Infectious Diseases identifies feasible, cost-effective packages of interventions and strategies across delivery platforms to prevent and treat HIV/AIDS, other sexually transmitted infections, tuberculosis, malaria, adult febrile illness, viral hepatitis, and neglected tropical diseases. The volume emphasizes the need to effectively address emerging antimicrobial resistance, strengthen health systems, and increase access to care. The attainable goals are to reduce incidence, develop innovative approaches, and optimize existing tools in resource-constrained settings.
