In many endemic areas, severely infected individuals may suffer fibrosis of the bladder, kidney damage, bladder cancer, and death if untreated. This, however, depends on several factors such as host-parasite genetics, degree and length of exposure, intensity of infection, host immune response to the parasites, and coinfections with other tropical diseases such as malaria and HIV-1.

disease has been found to expand geographically with a global increase of cases of 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.

Leishmaniasis is a vector-borne tropical/subtropical disease caused by an intracellular parasite transmitted to humans by sand fly bite. It is endemic in Asia, Africa, the Americas, and the Mediterranean region. Worldwide reports include 1.5–2 mil

lion new cases each year, more than 300 million at risk of acquiring the disease, and 70,000 deaths per year. Clinical features depend on the Leishmania species and immune response of the host, varying from localized cutaneous disease to visceral form with potentially fatal outcome; however, the common presentation is either cutaneous, mucocutaneous, or visceral leishmaniasis. Many therapeutic agents are being used in Leishmania treatment, but the only effective treatment is achieved with current pentavalent antimonials. WHO considers Leishmaniasis as one of the “Neglected Tropical Diseases” that continues to be prevalent despite international, national, and local efforts towards its control and elimination over the last decade. This chapter reviews the global perspective of Leishmaniasis with increasing recognition of emerging “Atypical forms” and new surge of disease across the world mainly due to increasing conflicts in endemic areas leading to forced migration among other causes. All these challenges related to environment, disease, and vector pose major implications on WHO’s leishmaniasis control and elimination plan.

There is widespread recognition of the growing threat of infectious disease epidemics and pandemics spreading across countries or continents—especially following the recent Ebola and COVID-19 pandemics. Vulnerable groups (including children, olde

r adults, ethnic minorities and other at-risk groups) have disproportionately borne the brunt of significant health, social, and economic effects of these epidemics and pandemics, with varying degrees of support received depending on the context. While many argue that communities should or need to play a critical role in supporting and leading preparedness and response efforts, work still needs to be done to engage them effectively. In many instances, modes of engagement with communities—especially by state authorities–have come too late, often as an afterthought are not adequately thought through and have undermined public trust in and support for, disease prevention and control measures

have highlighted the need for countries to continuously develop, strengthen, and maintain capacities required under the International Health Regulations (2005) (IHR (2005)).
Developing capacities for health security in a country requires the engagement of public and private entities across a broad range of sectors, including human and animal health, agriculture, environment, finance, security, emergency management, education, and transportation. The World Health Organization (WHO) is mandated through various resolutions, decisions, and reports of the World Health Assembly, and through the IHR (2005), to provide technical guidance and support to its Member States in developing, strengthening, and maintaining their health systems, including capacities required under the IHR (2005).
For countries to better prevent, prepare for, detect, notify, respond to, and recover from public health emergencies, they must build and maintain IHR core capacities and support the strengthening of health emergency prevention, preparedness, response, and resilience (HEPR) capacities. National Action Plans for Health Security (NAPHS), as capacity development plans, provide the tasks and resources needed to ensure adequate capacities are in place to prevent, detect, respond to, and recover from public health events in a sustainable manner. Investing in the resilience of these capacities within national health systems at national and local levels not only improves national health security but also helps safeguard economic, social, and political developments.

the planet. We rely on land and sea for the production of safe and quality foods for our daily nourishment. Pests and disease epidemics negatively impact the quality, quantity and safety of our food sources, and cripple economic growth and efficiencies in production. Furthermore, the epidemic and endemic levels of the pathogens and disease vectors can be difficult to control. This is why FAO stresses and promotes the special efforts required for cost-effective preventive measures rather than the more expensive control, disinfestation, treatment and disposal measures. When preventive measures are late or difficult, preparedness and contingency plans must be in place to enable rapid response. Early warning systems, based on close monitoring, surveillance, and timely reporting are fundamental to warn and empower communities to safeguard their livelihoods and assets by enhancing disease and pest prevention measures and for government services to take immediate measures to protect communities and national economies.

An economic burden analysis shows that economic losses from NCDs (direct and indirect costs) comprise 2.3 trillion tenge, equivalent to 4.5% of gross domestic product in 2017. An intervention costing analysis provides an estimate of the funding required to implement a set of policy interventions for prevention and clinical interventions. A cost–benefit analysis compares these implementation costs with the estimated health gains and identifies which policy packages would give the greatest returns on investment. For example, the salt policy package achieved a benefit-to-cost ratio of 118.4 over 15 years, a return of more than 118 tenge for every 1 tenge invested.

International study of Asthma and Allergies in Childhood (ISAAC) Phase III. Asthma symptoms were assessed from centres that completed GAN Phase I and ISAAC Phase I (1993–95), ISAAC Phase III (2001–03), or both. We included individuals from two age groups (children aged 6–7 years and adolescents aged 13–14 years) who self-completed written questionnaires at school. We estimated the 10-year rate of change in prevalence of current wheeze, severe asthma symptoms, ever having asthma, exercise wheeze, and night cough (defined by core questions in the questionnaire) for each centre, and we estimated trends across world regions and income levels using mixed-effects linear regression models with region and country income level as confounders.
Overall, 119 795 participants from 27 centres in 14 countries were included: 74 361 adolescents (response rate 90%) and 45 434 children (response rate 79%). About one in ten individuals of both age groups had wheeze in the preceding year, of whom almost half had severe symptoms. Most centres showed a change in prevalence of 2 SE or more between ISAAC Phase III to GAN Phase I. Over the 27-year period (1993–2020), adolescents showed a significant decrease in percentage point prevalence per decade in severe asthma symptoms (–0·37, 95% CI –0·69 to –0·04) and an increase in ever having asthma (1·25, 0·67 to 1·83) and night cough (4·25, 3·06 to 5·44), which was also found in children (3·21, 1·80 to 4·62). The prevalence of current wheeze decreased in low-income countries (–1·37, –2·47 to –0·27], in children and –1·67, –2·70 to –0·64, in adolescents) and increased in lower-middle-income countries (1·99, 0·33 to 3·66, in children and 1·69, 0·13 to 3·25, in adolescents), but it was stable in upper-middle-income and high-income countries.
Trends in prevalence and severity of asthma symptoms over the past three decades varied by age group, country income, region, and centre. The high worldwide burden of severe asthma symptoms would be mitigated by enabling access to effective therapies for asthma.
