Chikungunya virus (CHIKV) is currently one of the most relevant arboviruses to public health. It is a member of the Togaviridae family and alphavirus genus and causes an arthritogenic disease known as chikungunya fever (CHIKF). It is characterized by a multifaceted disease, which is distinguished fr...om other arbovirus infections by the intense and debilitating arthralgia that can last for months or years in some individuals. Despite the great social and economic burden caused by CHIKV infection, there is no vaccine or specific antiviral drugs currently available. Recent outbreaks have shown a change in the severity profile of the disease in which atypical and severe manifestation lead to hundreds of deaths, reinforcing the necessity to understand the replication and pathogenesis processes. CHIKF is a complex disease resultant from the infection of a plethora of cell types. Although there are several in vivo models for studying CHIKV infection, none of them reproduces integrally the disease signature observed in humans, which is a challenge for vaccine and drug development. Therefore, understanding the potentials and limitations of the state-of-the-art experimental models is imperative to advance in the field. In this context, the present review outlines the present knowledge on CHIKV epidemiology, replication, pathogenesis, and immunity and also brings a critical perspective on the current in vitro and in vivo state-of-the-art experimental models of CHIKF.

The spread of Severe Acute Respiratory Syndrome - Coronavirus 2 (SARS-CoV-2) continues to progress, causing damage in several countries of the world due to its rapid transmissibility and significant mortality rates, despite government measures to contain its tra...nsmission, such as movement control, the closing of schools, bans on travel and public gatherings, the mandatory use
of masks, and hand hygiene. The coronavirus disease (COVID-19) has clinical manifestations that are similar to those found in other infections also transmitted through the airways, such as pulmonary tuberculosis (TB) Although TB is a global health problem, it is a curable disease, with affordable treatment and prevention. Nonetheless, it remains one of the leading
causes of death from a single infectious agent worldwide, a situation threatened by COVID-19.

Key questions
What is already known?
Critical illness is common throughout the world and COVID-19 has caused a global surge of critically ill patients.
There are large gaps in the quality of care for critically ill patients, especially in low-staffed and low-resourced settings, and mortal...ity rates are high.
Essential Emergency and Critical Care (EECC) is the effective lifesaving care of low-cost and low-complexity that all critically ill patients should receive in all wards in all hospitals in the world.
What are the new findings?
The clinical processes that comprise EECC and the essential care of critically ill patients with COVID-19 have been specified in a large consensus among clinical experts worldwide.
The resource requirements for hospitals to be ready to provide this care has been described.
What do the new findings imply?
The findings can be used across medical specialties in hospitals worldwide to prioritise and implement essential care for reducing preventable deaths.
Inclusion of the EEEC processes could increase the impact of pandemic preparedness and response programmes and policies for health systems strengthening.

This Study presents the key results of a research that analyses the implications of an ambitious agroecological transition across Europe, following the TYFA scenario. Published in 2018, what it proposes by 2050 is fully aligned with the objectives that the European Farm to Fork and Biodiversity stra...tegies aim to achieve by 2030, in particular regarding the decrease in pesticides, nitrogen, and antibiotics on the supply side, and the transition towards more plant-based diets on the demand side. Using a world biomass balance model (GlobAgri-AgT), the impact of the TYFA scenario in the EU on world land use, the EU physical trade balance, the provision of calories and global food security is analysed in addition to key policy levers to spur the transition.

The climate crisis has many consequences – among them widespread health impacts that will lead to immense societal, ecological, and economic harm.
Over the past two decades multiple large-scale reviews on climate change and health have made clear the need for a multi-sectoral approach to target t...he drivers and impacts of climate change, biodiversity loss, and ecosystem degradation. Despite this abundance of scientific evidence underscoring urgency of action, policy implementation responses lag behind. Even at COP26, itself delayed due to an ongoing pandemic, health continues to be considered by many countries a problem independent from climate and environment.

The term “Long COVID-19” covers a wide spectrum of symptoms that can occur or persist weeks and even months after an acute infection, not only after severe but also after initially mild courses. Primary symptoms are exhaustion and fatigue, but also dyspnea on exertion,... headache and arthralgia, palpitations, concentration disorders and depressive symptoms in previously healthy individuals. The symptoms may fluctuate within hours or days. This chapter summarizes current knowledge (which is still limited, as of the end of January 2021).
