Dengue is a mosquito-borne viral disease that occurs mainly in the tropics and subtropics but has a high potential to spread to new areas. Dengue infections are climate sensitive, so it is important to better understand how changing climate factors affect the potential for geographic spread and futu...re dengue epidemics. Vectorial capacity (VC) describes a vector's propensity to transmit dengue taking into account human, virus, and vector interactions. VC is highly temperature dependent, but most dengue models only take mean temperature values into account. Recent evidence shows that diurnal temperature range (DTR) plays an important role in influencing the behavior of the primary dengue vector Aedes aegypti. In this study, we used relative VC to estimate dengue epidemic potential (DEP) based on the temperature and DTR dependence of the parameters of A. aegypti. We found a strong temperature dependence of DEP; it peaked at a mean temperature of 29.3°C when DTR was 0°C and at 20°C when DTR was 20°C. Increasing average temperatures up to 29°C led to an increased DEP, but temperatures above 29°C reduced DEP. In tropical areas where the mean temperatures are close to 29°C, a small DTR increased DEP while a large DTR reduced it. In cold to temperate or extremely hot climates where the mean temperatures are far from 29°C, increasing DTR was associated with increasing DEP. Incorporating these findings using historical and predicted temperature and DTR over a two hundred year period (1901-2099), we found an increasing trend of global DEP in temperate regions. Small increases in DEP were observed over the last 100 years and large increases are expected by the end of this century in temperate Northern Hemisphere regions using climate change projections. These findings illustrate the importance of including DTR when mapping DEP based on VC.

At the end of 2023, an estimated 117.3 million people worldwide were forcibly displaced due to persecution, conflict, violence, human rights violations and events seriously disturbing the public order. The latest Global Trends report, published in June 2024, provides key statistical trends on forc...ed displacement. It includes the latest official statistics on refugees, asylum-seekers, internally displaced and stateless people, as well as the number of refugees who have returned home

Preliminary overview of refugees and migrants self-reported impact of COVID-19
The study surveyed over 30,000 refugees and migrants living in 170 countries. Many of the respondents had fled war or dire economic conditions in their home country only to be faced with the additional challenges posed b...y COVID-19. Travel restrictions including border closures, suspension of resettlement travel, and last-minute deportation left many stranded or forced to stay in cramped, makeshift shelters or detention centers. Amid these uncertain, precarious conditions, many migrants described either a lack of access to health services or a fear of seeking them out — even if they were experiencing COVID-19 symptoms.

Human African trypanosomiasis (HAT), also called sleeping sickness, is a parasitic infection that almost invariably progresses to death, unless treatment is provided. HAT caused devastating epidemics during the 20th century. Thanks to ...sustained and coordinated efforts during the past 15 years the number of reported cases has fallen to a historic low. Fewer than 3,000 cases were reported in 2015, and the disease is targeted for elimination by the World Health Organization. Despite recent success, HAT still poses a heavy burden on the rural communities where this highly focal disease occurs, most notably in Central Africa. Since patients are also reported from non-endemic countries outside Africa, HAT should be considered in differential diagnosis for all travellers, tourists, migrants and expatriates who have visited or lived in endemic areas. In the absence of a vaccine, disease control relies on case detection and treatment, and vector control. Available drugs are sub-optimal, but ongoing clinical trials give hope for safer and simpler treatments.

In April and May 2015, Nepal was hit by two major earthquakes killing around 9,000 people and leaving many thousands more injured and homeless.
To optimize the speed and volume of critical humanitarian assistance, the HCT has developed this Plan to:
1. Reach a common understanding of earth...quake risk to ensure early action is taken when required.
2. Establish a minimum level of earthquake preparedness across clusters.
3. Build the basis for a joint HCT response strategy to meet the needs of affected people in the first 6 weeks to 3 months of a response.
4. Define considerations for detailed contingency planning on the basis of the worst-case scenario, especially around access and logistics.

The Multi-Cluster/Sector Initial Rapid Assessment (MIRA) is a joint needs assessment tool that can be used in sudden onset emergencies, including IASC System-Wide Level 3 Emergency Responses (L3 Responses).
The Indonesian government has reformed its laws, policies, and institutions to better manage disaster risk since the significant 2004 Indian Ocean Tsunami. The Government of Indonesia now has contingency plans for every disaster-prone city which identifies its vulnerabilities, outlines the relief re...sponse, and builds overall preparedness. In 2007, the government introduced a disaster management bill that incorporated disaster management prevention into disaster management response. In 2008, Indonesia created the National Disaster Management Agency (Badan Nasional Penanggulangan Bencana, BNPB). The new shift led to the strengthening of the country’s disaster management agency, and the addition of district branches and representatives. Despite the progress made, more work is needed at the local level as well as integration of disaster risk reduction in government departments.11 Under Indonesia’s 2007 Disaster Management law, provincial and district administrations are mandated to head disaster management during a crisis.

This document is the third iteration of the Flash Appeal for Ukraine, which was originally published on 1 March 2022 and revised once in mid-April. This updated Flash Appeal covers the period of 10 months following the onset of the war in Ukraine that started on 24 February 2022 (i.e., from March to... December 2022). The financial requirement of this Flash Appeal reflects the humanitarian needs from March until the end of 2022, taking into account the funding status and the response achievements to date, as well as the realistic projection of response capacity in the second half of the year.
