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.

Le développement d’une immunité face à un agent pathogène à la suite d’une infection naturelle comporte plusieurs étapes et prend généralement une à deux semaines. Une infection virale entraîne immédiatement une réponse immunit...aire innée, non spécifique, au cours de laquelle les macrophages, les neutrophiles et les cellules dendritiques ralentissent la progression du virus et peuvent même éviter l’apparition de symptômes. Cette réponse non spécifique est suivie d’une réponse adaptative, au cours de laquelle l’organisme produit des anticorps qui se lient spécifiquement au virus. Ces anticorps sont des protéines appelées immunoglobulines. L’organisme produit également des lymphocytes T qui reconnaissent et éliminent les cellules infectées par le virus. Cette réponse adaptative permet parfois d’éliminer le virus de l’organisme et, si elle est suffisamment forte, d’éviter l’aggravation de la maladie ou la réinfection par le même virus. Ce processus est souvent mesuré par la présence d’anticorps dans le sang.

The World Health Organization invites clinicians and patients to collect information on COVID-19 in a systematic way and contribute clinical data to the WHO Clinical Platform to expand our knowledge on Post-COVID-19 condition, and support patient care and public health interventions.
WHO’s Post... COVID case report form (CRF) has been designed to report standardized clinical data from individuals after hospital discharge or after the acute illness to examine the medium- and long-term consequences of COVID-19. The forms will be available in multiple languages.

This document aims to describe a minimum set of surveillance activities recommended at the national level to detect and monitor the relative prevalence of SARS-CoV-2 variants and outline a set of activities for the characterization and assessment of risk posed by these variants. A set of indicators ...is also provided to standardize monitoring and public reporting of variant circulation.
The document is primarily intended for national and sub-national public health authorities and partners who support implementation of surveillance for SARS-CoV-2 variants

The BMJ "practice pointer" inlcudes a one-page visual summary of assessment and initial management of patients with persistant symptoms following acute SARS-CoV-2 infection
This bi-weekly brief details the latest developments in scientific knowledge and public health policy from around the world as well as updates to the COVID-19-related guidance from Africa CDC, WHO and other public health agencies.
The Committee discussed the implications for preparedness for smallpox-like events reflected by the ongoing COVID-19 pandemic. The Committee noted how quickly diagnostics and vaccines could be developed and deployed when resources and political will were abundant. This rapidity was also due to the f...act that the genetic sequence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had been shared worldwide. It was noted that in one country SARS-CoV-2 had been reconstructed in a laboratory from the viral genome sequence before the first case of COVID-19 had been reported, highlighting the benefits of synthetic biology technologies for accelerated development of diagnostics as well as the oft-described potential risks. Lessons learned about clinical care during the COVID-19 pandemic were also discussed.

Multiple countries are reporting severe acute cases of hepatitis of unknown aetiology in children, in several
regions of the world. WHO has developed this clinical case report form (CRF) to support and facilitate reporting
of anonymized, patient-level data of acute hepatitis of unknown aetiology.

Rabies has an enormous impact on both agriculture and conservation biology, but its greatest burden is undeniably on public health. As such, routine methods for rapid risk assessment after human exposures to rabies as well as applications for laboratory-based surveillance, production of biologicals ...and management of this infectious disease are critical. Given its mandate to improve human health and control disease among its Member States, WHO has led the production of this fifth edition of Laboratory techniques in rabies.

A person who lives in or has traveled in the previous 14 days to areas with dengue transmission, and presents with acute fever that has typically lasted 2 to 7 days, and two or more of the following clinical manifestations: nausea or vomiting, exanthema, headache or retro-orbital pain, myalgia or ar...thralgia, petechiae or positive tourniquet test (+), leukopenia, with or without any warning sign or sign of severity. A suspected case is also considered to be any child who resides in or has traveled in the previous 14 days to an area with dengue transmission that presents acute febrile symptoms, usually for 2 to 7 days, without an apparent focus.
