The aim of this “model contingency plan” is to assist programme managers and planners in devel-oping a national, context-specific, dengue outbreak response plan in order to: (a) detect a dengue outbreak at an early stage through clearly defined and validated alarm signals; (b) precisely define w...hen a dengue outbreak has started; and (c) organize an early response to the alarm signals or an “emergency response” once an outbreak has started.

WHO recommends that pre-exposure prophylaxis (PrEP) be offered as an additional prevention choice for HIV-negative individuals at substantial risk of HIV infection as part of combination prevention approaches.
HIV drug resistance has been rarely reported among PrEP users who tested HIV positive i...n randomized controlled trials or open-label studies. However, PrEP-selected HIV drug resistance could potentially negatively impact the effectiveness of treatment options among PrEP users who acquire HIV, since there is a potential for overlapping resistance profiles between antiretroviral drugs used for both PrEP and first-line antiretroviral therapy.

The module provides an overview of factors to consider when monitoring the safety of COVID-19 vaccines administered to pregnant and breastfeeding women. It describes how national routine AEFI surveillance should be adapted to cater for this specific group of population using both pass...ive and active surveillance methods. Specific considerations and limitations of each method are provided as well as tools for implementation.

Recency assays use one or more biomarkers to identify whether HIV infection in a person is recent (usually within a year or less) or longstanding. Recency assays have been used to estimate incidence in representative cross-sectional surveys and in epidemiological studies to better understand the pat...terns and distributions of new and longstanding HIV infections.
This technical guidance outlines best practices regarding the appropriate use of HIV recency assays for surveillance purposes and updates 2011 technical guidance from the World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS (UNAIDS) on the use of HIV recency assays.

This publication aims to provide updated guidance on the specific use of yellow fever laboratory assays in the context of surveillance to be used across the Global Yellow Fever Laboratory Network for disease surveillance. In the recent years, new commercial assays became available and are now recomm...ended for use by WHO and this publication will support national program on the use of compound laboratory assays as per the most recent recommended testing algorithms. This piece is aligned with the elimination effort set in the comprehensive global strategy to eliminate yellow fever epidemics (EYE) strategy 2017-2026 and where its advisory laboratory technical working group actively contributed to its development. The target audiences are policy-makers and health workers.
