Communities affected by a disaster often lack basic water
and sanitation facilities. They are likely to be traumatized and
vulnerable to disease. Disruption of familiar practices or the
relocation to new environments can result in a deterioration
in existing hygiene behaviours. This, in turn, wi...ll contribute to
an increased risk of disease transmission and epidemics. This
technical note explains why hygiene promotion is important in
emergencies and describes how to carry it out.

Each year, the WHO Global TB Report provides a comprehensive and up-to-date assessment of the TB epidemic, and of progress in prevention, diagnosis and treatment of the disease, at global, regional and country levels. This is done in the context of global TB commitments, strategies and targets.
The... 2021 edition of the report has been produced in a new and more web-centric format. This is designed to make the content available in smaller (more “bite-sized”) chunks that are easier to read, digest, navigate and use. There is a short and slim report PDF with 30 pages of main content plus six short annexes. This is accompanied by expanded and more detailed digital content on web pages. The total amount of content remains similar to that of previous years.
Available in English, French, Arabic and Chinese

Thailand is exposed to flooding, landslides, drought, earthquakes, tsunamis, heat waves, forest fires, and epidemics. Thailand is also exposed to technological hazards such as chemical accidents. Flooding is the natural hazard with the most significant impact on human life, livelihoods, and the econ...omy for the country. The occurrence of droughts has increased in recent years due to the effects of the El Niño-Southern Oscillation (ENSO) cycle, which brings drier-than-average rainfall conditions. Drought has adversely impacted the country’s agriculture sector, which employs around one third of the country’s workforce.

Dengue Epidemiology
The first record of a case of probable dengue fever is in a Chinese medical encyclopedia from the Jin Dynasty (265–420 AD) which referred to a “water poison” associated with flying insects. The first recognized Dengue epidemics occurred almost simultaneously in Asia, Afr...ica, and North America in the 1780s, shortly after the identification and naming of the disease in 1779. The first confirmed case report dates from 1789 and is by Benjamin Rush, who coined the term "breakbone fever" because of the symptoms of myalgia and arthralgia.

Over the past twenty years, huge efforts made by a broad coalition of stakeholders curbed the last epidemic and brought the disease to the brink of elimination. In this paper, the latest figures on disease occurrence, geographical distribution and control activities are presented. Strong evidence in...dicates that the elimination of sleeping sickness ‘as a public health problem’ by 2020 is well within reach. In particular, fewer than one thousand new cases were reported in 2018, and the area where the risk of infection is estimated as moderate, high or very high has shrunk to less than 200,000 km2. More than half of this area is in the Democratic Republic of the Congo. The interruption of transmission of the gambiense form, targeted by the World Health Organization (WHO) for 2030, will require renewed efforts to tackle a range of expected and unexpected challenges. The rhodesiense form of the disease represents a small part of the overall HAT burden. For this form, the problem of under detection is on the rise and, because of an important animal reservoir, the elimination of disease transmission is not envisioned at this stage.

Gambiense human African trypanosomiasis is a deadly infectious disease affecting West and Central Africa, South Sudan and Uganda, and transmitted between humans by tsetse flies. The disease has caused several major epidemics, the latest one in the 1990s. Thanks to recent innovations such as rapid di...agnostic tests for population screening, a single-dose oral treatment and a highly efficient vector control strategy, interruption of transmission of the causative parasite is now within reach. If indeed gHAT has an exclusively human reservoir, this could even result in eradication of the disease. Even if there were an animal reservoir, on the basis of epidemiological data, it plays a limited role. Maintaining adequate postelimination surveillance in known historic foci, using the newly developed tools, should be sufficient to prevent any future resurgence.

In their 2015 declaration "Transforming our world: the 2030 Agenda for Sustainable Development", Member States pledged to end the epidemics of AIDS, tuberculosis, malaria and neglected tropical diseases by 2030, and to combat hepatitis and other communicable diseases. This report reviews progress an...d challenges in the global response to reduce the burden of these diseases in the context of the Millennium Development Goals, and looks ahead to identify the strategies and approaches that will be needed to accelerate progress during the new development era. The report was developed by WHO's Cluster for HIV/AIDS, TB, Malaria and Neglected Tropical Diseases in 2015.

Leishmaniasis is a vector-borne disease with a broad global distribution and an increasing number of recorded cases worldwide. However, it is still one of the world's most neglected diseases. Over the last decades, the disease has been found to expand geographically with a global increase of cases o...f visceral and cutaneous leishmaniasis increasing the public health problems associated with the disease epidemics. The reported range expansion of the diseases has been associated with range expansions of vector populations in response to climate change. Leishmaniasis is caused by protozoan parasites of the genus Leishmania. The transmission can either be zoonotic and/or anthroponotic through the bite of an infected female phlebotomine sandfly. In Eurasia and Africa, all vector-competent sandfly species belong to the genus Phlebotomus. Cutaneous leishmaniasis (CL) is the most common form of leishmaniasis. In the ‘old world’, it is caused by five currently recognized Leishmania species: L. major, L. tropica and L. aethiopica (being main causative parasites) as well as L. infantum and L. donovani. Visceral leishmaniasis (VL), another common and more severe form of leishmaniasis, is only associated with the Leishmania species L. infantum and L. donovani. The specific Leishmania species cause different clinical symptoms in humans.

Chikungunya virus (CHIKV) is a re-emerging mosquito borne alphavirus responsible
for the recent outbreak in the Americas. Immunologically naïve population in the Americas favors the spread of epidemics. Chikungunya fever is characterized by an abrupt febrile illness, polyarthralgia and maculopapul...ar rash. In chikungunya fever, shock or severe hemorrhage is very rarely observed; the onset is more acute and the duration of fever is shorter than dengue disease. The pain is much more pronounced and localized to the joints and tendons in chikungunya fever, in comparison to dengue fever. There is no specific and effective antiviral therapy and vaccines are still in trails. The only effective preventive measures consist of individual protection against mosquito bites and vector control. Disease prevention is important due to the
economic burden it entails. Clinicians need to distinguish chikungunya fever between dengue fever and other diseases to give a successful treatment and prevent disease spreading.

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 nu...mber 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.

The Regional Action Framework for Noncommunicable Disease Prevention and Control provides a unified vision of objectives and recommended actions to combat the noncommunicable disease (NCD) epidemic in the Western Pacific Region. Implementation should be supported by cross-sectoral coordination..., sustainable financing, evidence-based policy, and community engagement, tailored to each Member State’s unique context. In doing so, Member States are encouraged to transform a disease treatment-centered “sick system” into a “health system” in which a population’s health and well-being enable socioeconomic development.

This country profile presents a summary and analysis of Argentina's status with yellow fever. It is part of a series of profiles on this topic, each focusing on a different country in the Region of the Americas. Argentina's geographical location presents a wide territorial extension throughout diffe...rent latitudes, which determines a wide climatic variety, maintaining the conditions for the enzootic transmission of the yellow fever virus in jungle areas of the northeast of the country bordering Brazil and Paraguay. After controlling the major urban epidemics that hit the port city of Buenos Aires in the 20th century, Argentina maintains foci of enzootic activity in the northeast and isolated human cases for jungle acquisition. The increases in viral activity usually occur in a regional context of epizootics that affect southern Brazil and eastern Paraguay. Argentina has not presented autochthonous cases since 2008. Outbreaks have been sporadic with long intervals without evidence of viral activity.

As the Group of Eight (G8) world leaders meet in Saint Petersburg, Russia for this year’s G8 Summit, it is important to take stock of international efforts to finance the response to the global HIV/AIDS epidemic. Financing a sufficient and sustained response to the epidemic has emerged as one of t...he world’s greatest challenges, and one that will be with us for the foreseeable future. Often, those countries most affected are also least able to respond, increasing their vulnerability to HIV/AIDS and in turn further complicating their ability to address the epidemic, as is the case for many nations in sub-Saharan Africa. In addition, concerns have been raised about “second wave” nations, particularly China, India, and Russia, which stand on the brink of generalized epidemics if more is not done now

This threat assessment addresses the implications of the ongoing Marburg virus disease (MVD) outbreak in
Rwanda for the European Union/European Economic Area (EU/EEA). MVD is a severe disease in humans and,
although uncommon, it has the potential to cause epidemics with significant case fatality. ...All recorded MVD
outbreaks to date have originated in Africa. MVD is not an airborne disease and is considered not to be
contagious before symptoms appear. Direct contact with the blood and other body fluids of infected people
and animals or indirect contact with contaminated surfaces and materials like clothing, bedding and medical
equipment is required for transmission. The risk of infection is minimised when proper infection prevention and
control precautions are strictly followed. There is no approved treatment or vaccine for MVD; however, several
pharmaceuticals and candidate MVD vaccines are under investigation.
