An example of integration of research into epidemic response.
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.

To save the lives of mothers and their babies, mitigate complications, and limit the spread of disease, it is critical that recommendations are made on the prevention, treatment, and surveillance of women who are exposed to EVD, acquire EVD during pregnancy or breastfeeding, or survive EVD with ongo...ing pregnancies. These guidelines are the first to provide such recommendations.

The following protocol has been designed to investigate the First Few X cases (FFX) and their close contacts. It is envisioned that the FFX 2019-nCoV investigation will be conducted across several countries or sites with geographical and demographical diversity. Using a standardized protocol such a...s the protocol provided here, epidemiological exposure data and biological samples can be systematically collected and shared rapidly in a format that can be easily aggregated, tabulated and analyzed across many different settings globally for timely estimates of 2019-nCoV infection severity and transmissibility, as well as to inform public health responses and policy decisions. This is particularly important in the context of a novel respiratory pathogen, such as 2019-nCoV

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)

This interim guidance has been updated with advice on safe and appropriate home care for patients with coronavirus disease 2019 (COVID-19) and on the public health measures related to the management of their contacts.
Scientific Brief 9 July 2020
The following protocol has been designed to investigate the extent of infection, as determined by seropositivity in the general population, in any country in which COVID-19 virus infection has been reported. Each country may need to tailor some aspects of this protocol to align with public health, l...aboratory and clinical systems, according to capacity, availability of resources and cultural appropriateness. However, using a standardized protocol such as this one below, epidemiological exposure data and biological samples can be systematically collected and shared rapidly in a format that can be easily aggregated, tabulated and analyzed across many different settings globally for timely estimates of COVID-19 virus infection severity and attack rates, as well as to inform public health responses and policy decisions. This is particularly important in the context of a novel respiratory pathogen, such as COVID-19 virus

This document updates the earlier version published in April 2020. In recent weeks, information on the potential use of chloroquine or hydroxychloroquine for the treatment of people with COVID-19 has been disseminated in academic journals and public media. Although there are now ongoing clinical tri...als testing the efficacy and safety of several medicines for COVID-19, as of the date of this document, there is a lack of quality evidence to demonstrate chloroquine and/or hydroxychloroquine are effective in the treatment of COVID-19. Evidence is recently emerging via small studies with sub-optimal methodologies that are conflicting.

Clinical care for severe acute respiratory infection: toolkit: COVID-19 adaptation
Whole-genome sequencing (WGS) provides a vast amount of information and the highest possible resolution for pathogen subtyping. The application of WGS for global surveillance can provide information on the early emergence and spread of AMR and further inform timely policy development on AMR control.... Sequencing data emanating from AMR surveillance may provide key information to guide the development of rapid diagnostic tools for better and more rapid characterization of AMR, and thus complement phenotypic methods. This document addresses the applications of WGS for AMR surveillance, including the benefits and limitations of current WGS technologies

The World Health Organization organized a Consultation of National Leprosy Programme managers, partners and affected persons to discuss the draft Global Leprosy Strategy, 2021--2030. This virtual event took place from 26 to 30 October 2020. It was attended by more than 450 stakeholders. Contribution...s were shared through 70 presentations made by stake holders from all Regions. The presentations covered the key strategic approaches: global context, challenges in countries, contact tracing and post exposure prophylaxis, disability care, interruption of transmission and elimination of disease, stigma and d iscrimination, research. In addition to numerous comments received through the chat box and by email, the conclusions and recommendations of this Consultation will guide finalizing the post 2020 Global Leprosy Strategy.

Project protocol
Introduction Ready-to-eat food sold in the street represents a global phenomenon, more common in urbanized areas, that constitutes an important dietary source in populations from low- and middle-income countries. However, research on the kind of street food offered and its composit...ion is scarce. The main objective of this study is to characterize the urban street food environment, including vending places, the food offered, its nutritional composition, food purchasing patterns and advertising.
Methods and analysis This protocol provides a framework for a stepwise, standardized characterization of the street food environment; it consists of three steps that are of increasing complexity and demand increasingly great human and technical resources. Step 1 comprises identification of street food vending sites and characterization of the products available; this stage may be complemented with an evaluation of food advertising in the streets. Step 2 comprises description of street food purchasing patterns, by direct observation. Step 3 requires collection of food samples for bromatological analysis. Different levels of data collection may be defined for each step; hereafter, these are presented as core and expanded evaluations. For the most part, data analysis involves descriptive statistics and basic spatial analysis.
