When setting national drinking-water quality regulations and standards, many countries consider the WHO Guidelines for drinking-water quality (GDWQ). To better understand the extent to which the GDWQ are used and reflected in these standards, this global review summarizes information from 104... countries and territories on values specified in national drinking-water quality standards for aesthetic, chemical, microbiological and radiological parameters.
The information provided will support regulatory agencies and other key stakeholders to access and compare data when setting or revising national drinking-water quality regulations and standards.

Guidance has been updated on a number of chemicals: asbestos, bentazone, chromium, iodine, manganese, microcystins, nickel, silver, tetrachloroethene and trichloroethene. Guidance has also been added for chemicals not previously assessed in the Guidelines: anatoxin-a and analogues, cylindrospermopsi...ns and saxitoxins. The new guidance on organotins has replaced the prior guidance focused on dialkyltins. With these updates, the guideline values for tetrachloroethene and trichloroethene have been revised while new guideline values for cylindrospermopsins, manganese, microcystins, and saxitoxins have been established .
Updated information on cyanobacteria has been included, introducing an alert level framework for early-warning and to guide short-term management responses. Guidance has also been updated in the sections on adequacy of water supply, climate change, emergencies, food production and processing, and radiological aspects, particularly on managing radionuclides when exceeding WHO screening values and guidance levels.

In this contingency planning guidance, a set of actions to prepare for emergencies from all hazards and to help minimize their impact, is proposed. These actions include the development, implementation, simulation, monitoring and regular update of risks-based contingency plans.
The Strategic Framework for Emergency Preparedness is a unifying framework which identifies the principles and elements of effective country health emergency preparedness. It adopts the major lessons of previous initiatives and lays out the planning and implementation process by which countries can ...determine their priorities and develop or strengthen their operational capacities. The framework capitalizes on the strengths of current initiatives and pushes for more integrated action at a time when there is both increased political will and increased funding available to support preparedness efforts.

As of October 2017, the global database comprised almost 30 000 records, including results from bioassays to measure phenotypic resistance, and biochemical and molecular tests for resistance mechanisms. The current report presents an overview of data on malaria vector resistance for 2010 to 2016. It... aims to provide the baseline for subsequent status updates and to identify any temporal trends. An online mapping tool called Malaria Threats Map allows further interactive exploration of available data.

The WHO Global Burden of Disease (GBD) study measures the burden of
disease using the disability-adjusted life year metric (DALY). The DALY metric
was developed to assess the burden of disease consistently across diseases,
risk factors and regions. A consistent and comparative description of the ...burden
of diseases and injuries and the risk factors that cause them is important as it
can inform health decision-making and health care planning.

It is recommended that egg based quadrivalent vaccines for use in the 2019-2020 northern hemisphere influenza season contain the following:
an A/Brisbane/02/2018 (H1N1)pdm09-like virus;
an A(H3N2) virus to be announced on 21 March 2019*;
a B/Colorado/06/2017-like virus (B/Victoria/...2/87 lineage); and
a B/Phuket/3073/2013-like virus (B/Yamagata/16/88 lineage).
It is recommended that the influenza B virus component of trivalent vaccines for use in the 2019-2020 northern hemisphere influenza season be a B/Colorado/06/2017-like virus of the B/Victoria/2/87-lineage.
* In light of recent changes in the proportions of genetically and antigenically diverse A(H3N2) viruses, the recommendation for the A(H3N2) component has been postponed.
