Zika and dengue viruses remain significant public health threats. These viruses share the same Aedes (Stegomyia) mosquito vectors and geographic distributions but infections cannot be readily distinguished clinically and need to be differentiated from each other, and from other circulating arboviral... and non-arboviral pathogens, using laboratory tests. This document provides guidance on current testing strategies for Zika and dengue virus infections with updates to the previous interim guidance for laboratory testing for ZIKV, addressing pregnant and non-pregnant patients respectively, and incorporates current guidance for dengue virus diagnostic testing. The choice of laboratory assays and interpretation of test results require careful consideration of epidemiology, patient history, and limitations of existing diagnostic tests.
This interim guidance is for use by staff of laboratories testing for Zika and dengue virus infections and for clinical practitioners and public health professionals providing clinical management or surveillance.

Polymerase Chain Reaction (PCR) has significantly helped in early diagnosis and commencement of specific interventions for diseases control. It also plays a critical role in understanding the disease epidemiology and unraveling the transmission dynamics of the disease. This manual intends to p...rovide primary guidelines to assist health lab personnel in developing countries to establish a PCR diagnostic facility for efficient support to patient care as well as public health actions.

Objective: To describe the temporal and geographical distribution of Zika virus infection, and associated neurological disorders, from 1947 to February 2016.
Vector-borne diseases are responsible for 17% of the global burden of communicable diseases and more than 500 000 deaths annually. The ambitious global targets for the control of vector-borne diseases come in the context of the (re-)emergence of diseases, increasing resistances to insecticides and u...ncertainty related to the financing of global vector control efforts. The United Nations 2030 Agenda with its related Sustainable Development Goals (SDGs), the New Urban Agenda adopted at the United Nations Conference on Housing and Sustainable Urban Development (Habitat III)
in Quito in 2016 and WHO’s Global vector control response 2017–2030 (WHO, 2017a) emphasize the value of elevating multisectoral actions and strategies that extend beyond the health sector to the core of integrated vector control.
This policy brief underlines the important role housing conditions have in the transmission of vector-borne diseases and showcases interventions and policies the housing sector can contribute to effective, integrated and intersectoral vector-borne diseases management.

In recent decades we have seen progressive changes to global climate patterns caused by anthropogenic impacts on the environment. These are likely to directly and indirectly affect human health, and are projected to continue and potentially
accelerate into the future. Neglected tropical diseases (N...TDs) and malaria are potentially particularly sensitive to these changes as they
are prevalent amongst vulnerable populations
in countries expected to experience the greatest
environmental change in the coming decade.

The WHO report on health preparedness for El Niño 2015-2016 describes the impact of this weather phenomenon on global public health. Strong El Niño events lead to extreme weather conditions, including droughts, floods, and storms, which increase the risk of diseases such as cholera, malaria, and d...engue fever. Particularly affected regions include Africa, Asia-Pacific, and Latin America, where water and food shortages and disease outbreaks are becoming more frequent.
The WHO supports countries through risk assessments, emergency plans, and disease surveillance to prevent outbreaks. Recommended measures include early warning systems, health preparedness in vulnerable areas, and better coordination between health and meteorological services to minimize the negative effects of El Niño on public health.
