During the past five decades, the incidence of dengue has increased 30-fold. Some 50–100 million new infections are estimated to occur annually in more than 100 endemic countries, with a documented further spread to previously unaffected areas; every year hundreds of thousands of severe cases ari...se, including 20 000 deaths; 264 disability-adjusted life years per million population per year are lost , at an estimated cost for ambulatory and hospitalized cases of US$ 514–1394, often affecting very poor populations. The true numbers are probably far worse, since severe underreporting and misclassification of dengue cases have been documented.

This guide is a revised edition to the previous version published in 2017.
This updated publication provides programme managers with a user-friendly tool that can: (i) analyse and draw conclusions from historic dengue datasets; (ii) identify appropriate alarm indicators that can predict forthcoming... outbreaks at smaller spatial scales; and (iii) use these results and analyses to build an early warning system to detect dengue outbreaks in real time and respond accordingly. This web-based tool can ensure enhanced, fast and secured communication between national and subnational levels, and standardized utilization of surveillance data.

A new report by the world’s largest humanitarian network warns that the number of people needing humanitarian assistance every year as a result of climate-related disasters could double by 2050. It estimates that the number of people in need of humanitarian assistance as a result of storms, droug...hts and floods could climb beyond 200 million annually – compared to an estimated 108 million today.
It further suggests that this rising human toll would come with a huge financial price tag, with climate-related humanitarian costs ballooning

The WHO Health Emergencies Programme is currently monitoring 118 events in the region. This week’s main articles cover the following events:
Coronavirus disease 2019 (COVID-19) in Togo
Measles in Chad
Ebola virus disease (EVD) in Équateur Province, Democratic Republic of the Congo.
Compared to the previous five-year assessment period 2011–2015, the current five-year period 2015–2019 has seen a continued increase in carbon dioxide (CO2 ) emissions and an accelerated increase in the atmospheric concentration of major greenhouse gases (GHGs), with growth rates nearly 20% high...er. The increase in the oceanic CO2 concentration has increased the ocean’s acidity.
The five-year period 2015–20191 is likely to be the warmest of any equivalent period on record globally, with a 1.1 °C global temperature increase since the pre-industrial period and a 0.2 °C increase compared to the previous five-year period.

What at first glance appears to be simple causality – climate change leading to more and more migration – has triggered intense academic debate over the past ten years because the circumstances are complex. There is need for a thorough analysis in the ground between denying the problem and asser...ting immediate causality. In international relations, migration induced by climate change and environmental degradation is increasingly recognized as a problem, whether in the framework of international climate policy, international migration policy, development cooperation, or international crisis management. But considering the dimension of these major challenges, only small steps have been taken so far. The scope of the problem continues to be underestimated. Climate change is jeopardizing the livelihoods of more and more people. It is a risk multiplier. Although understanding of the connection between climate change and migration has increased, many questions have yet to be answered. We need more knowledge to better support the people affected.

Notable progress has also been made on other key health indicators such as reducing maternal, infant and child deaths and malnutrition, increasing immunization coverage, eliminating infectious diseases such as polio and reducing the incidence of malaria, tuberculosis and diarrhoeal diseases.
But ...despite such substantial progress, the country now faces new and emerging new challenges such as the rising burden of noncommunicable diseases, increased risks associated with disasters, environmental threats and health emergencies during disease outbreaks including the COVID-19 pandemic that is a serious public health threat to Bangladesh. To establish a resilience system for future potential pandemics, the national capacity for emergency preparedness and early response to health emergencies needs to be bolstered considerably.
