WHO has published key planning recommendations for mass gatherings in the context of the current COVID-19 outbreak. The document provides guidance on containing risks of COVID-19 transmission associated with mass gathering events. The UN and WHO have urged governments around the world to take the mental health consequences of the pandemic seriously, and ensure widespread availability of mental health support. WHO discusses this in a recently released article and has published guidelines for communities and a children's book. An article released by WHO Regional Office for Europe introduces recently published technical guidance on preventing and managing the COVID-19 pandemic across longterm care services. WHO has released a framework for decision-making that proposes a step-wise approach to the assessment of the relative risks and benefits of conductin g mass vaccination campaigns in the context of COVID-19 (see 'Subject in Focus' below).

Large quantities of ash are generated every year by the various manufacturing industries as a waste by-product. This study aims to utilize waste by-product in concrete and to reduce its cost by replacing cement in parts with bottom ash. This research presents the results of the experimental investigations to study the use of bottom ash as partial replacement for cement in concrete and masonry units. Bottom ash is the coarser material, which falls into furnace bottom and constitutes about 20% of total ash content. The strength development for various percentage replacements (5-15%) of cement with bottom ash has been compared to control specimens of concrete and masonry.
