This document provides guidance on how to implement contact screening and chemoprophylaxis with single-dose rifampicin. The contents are logically ordered: counselling and obtaining consent, identification and listing of index case, listing of contacts, tracing of contacts, screening of contacts, ad...ministration of prophylactic drugs. Managerial aspects to undertake contact screeninig and chemoprophylaxis are also elaborated, including planning , training , supervision and drug management.

This American Thoracic Society Statement was prepared by a Committee of the Scientific Assembly on Environmental and Occupational Health at the request of the American Lung Association Occupational Health Expert Advisory Group to emphasize the continuing importance of silicosis as a major lung disea...se worldwide and the need for increasing efforts in prevention. Emphasis is placed on public health issues of silicosis rather than on important current research in pathologic mechanisms.

Silicosis is not a new disease; the impact of silica dust on respiratory function was observed by Hippocrates in 430 B.C. and in the 16th century by Agricol. In 1713, Rammazini described silicotic nodules in post-mortems of stone cutters presenting with respiratory symptoms. In the mid-late 1800s,... the introduction of mechanized tools in the mining sector rapidly increased levels of silica exposure, resulting in an increase in cases and our understanding of silicosis.

WHO strongly recommends discontinuation of the nerve tissue vaccine, and replacement with modern concentrated and purified cell culture derived vaccines (CCDV) and embryonated eggbased rabies vaccines.
These vaccines must comply with WHO criteria for potency and innocuity following satisfactory ass...essment in humans during well-designed field trials

This document summarizes several air quality measurement and modelling methods that can be used to estimate ground-level air pollutant concentrations and presents multiple approaches to monitoring ambient air pollution at different spatial and temporal scales. These methods are crucial for estimatin...g population exposures, which can be defined as the product of the pollutant concentration and the time over which a person is in contact with this pollutant.

Evidence shows that oral pre-exposure prophylaxis (PrEP) reduces the risk of contracting HIV during sexual intercourse by more than 90% when taken daily. It is for this reason the National HIV Prevention Strategy 2015-2020 (2018 Revision) emphasises the role of preexposure prophylaxis (PrEP) in ...reducing new HIV infections in Malawi.
The Ministry of Health has prioritised PrEP use among the populations most at-risk of HIV infection in Malawi: young women ages 10 to 24 years, sero-discordant couples, female sex workers, men who have sex with men, and other priority populations (such as members of the uniformed services, prisoners, and mobile populations).

There is no safe level of secondhand smoke exposure
Secondhand smoke can travel within multiunit housing and common areas through doorways, cracks in walls, electrical lines, ventilation systems and plumbing.
Opening windows and using fans does not completely remove secondhand smoke.
Heating, air... conditioning and ventilation systems cannot eliminate exposure to secondhand smoke.

Rapid review and case studies from Member States
The environment in which young people live, learn and play significantly affects their decisions about whether to consume alcohol. Environmental factors are the main risk factors driving alcohol consumption and related harm among young people. Environments that normalize alcohol consumption – term...ed alcogenic environments – include contexts with unregulated advertising and marketing of alcoholic beverages, higher alcohol outlet density, products designed to facilitate affordability and low prices of alcoholic beverages. A recent body of research evidence has emerged related to the measurement, functional significance and consequences of living in alcogenic environments. This includes findings on the complex and bidirectional interactions among alcohol acceptability, availability and affordability and how they create and perpetuate alcogenic environments. Comprehensive and enforced alcohol control policies are effective at delaying the age of onset and lowering alcohol prevalence and frequency among young people. Evidence consistently confirms the effectiveness of designing and implementing alcohol control policies that regulate upstream the drivers of alcogenic environment, including alcohol availability, acceptability and affordability. These policies need to be multipronged and address the complex interactions between these drivers and the local alcohol culture
