The purpose of this document is to present concise information on the current case definitions for dengue, chikungunya, and Zika proposed by PAHO, as well as information on the clinical phases and severity classification of dengue and chikungunya.
This report on global leishmaniasis surveillance follows those published in 2016–2023.2–6 Six indicators of leishmaniasis are publicly available from the Global Health Observatory (GHO).7 In addition to the GHO, country profiles with up to 30 indicators are published, with detailed data received... from 45 Member States.

In 2007, the Sixtieth World Health Assembly adopted resolution WHA60.13 on control of leishmaniasis, urging Member States, among other actions: to strengthen prevention, active detection and treatment of cases of both cutaneous and visceral leishmaniasis in order to decrease the disease burden; and ...to strengthen the capacity of peripheral health centres to deliver primary and secondary care, so that they provide appropriate affordable diagnosis and treatment and act as sentinel surveillance sites.

Human strongyloidiasis is a chronic parasitic disease caused by infection with Strongyloides stercoralis, a soil-transmitted helminth that is estimated to infect 300–600 million people worldwide. This neglected tropical disease (NTD) is endemic globally, predominately in the South-East Asia, Afric...an and Western Pacific regions, and in South and Central America. Strongyloidiasis has a wide range of clinical presentations, including subclinical disease, symptomatic disease (often with diarrhoea, abdominal pain and urticaria) and a rare but deadly complication of hyperinfection with disseminated disease. The feared complication of disseminated strongyloidiasis can occur in the setting of immunocompromising conditions (e.g. human T-cell lymphotropic virus type 1 infection and malignancies) or immunosuppressive medications (e.g. steroids) and has an estimated case-fatality rate exceeding 60%. The standard treatment for chronic S. stercoralis infection is oral medication with ivermectin.

Between epidemiological weeks (EW) 1 and 22 of 2024, a total of 9,541,015 suspected cases of dengue were reported, resulting in a cumulative incidence of 1,011 per 100,000 population. This represents an increase of 230% compared to the same period in 2023 and 421% compared to the average of the last... 5 years. Figure 1 shows the trend of suspected dengue cases as of EW 22.

The meeting of leprosy programme managers in the South-East (SE) Asia Region was convened by the WHO Regional Office for South-East Asia (WHO-SEARO) from 11 to 13 April 2023 in Kolkata, India. The meeting was attended by 40 participants, including 15 national focal points from nine countries, five e...xperts, partners, donors and WHO staff members, including those from the Global Leprosy Programme (GLP).
The objectives of the meeting were to:
- review the current situation and progress of leprosy elimination in the Member States;
- discuss the updates on the new guidance and tools from the Global Leprosy Programme;
- facilitate experience-sharing and catalyse discussions to identify innovative practices, solutions and remaining gaps across countries to enhance leprosy elimination activities; and
- determine priority actions and support needs for accelerating leprosy elimination in the Region.

ince the introduction of multidrug therapy (MDT), there has been significant progress in reducing the prevalence of leprosy and the occurrence of new cases. Global strategies have evolved with progress in reducing the disease burden. Encouraged by the decrease in the number of cases on treatment, th...e World Health Assembly passed a resolution calling on Member States to accelerate efforts towards global elimination of leprosy as a public health problem by 2000.
Most countries reached the milestone by 2010. The global strategies for 2006–2015 focused on sustaining high-quality leprosy services and early diagnosis. Reduction in the disease burden was measured in terms of grade-2 disability (G2D) or visible deformities in new cases. Since 2016, the strategies have included reduction of stigmatization of people with leprosy.

The Global Leprosy Strategy 2021–2030 “Towards zero leprosy” was developed through a broad consultative process with all major stakeholders during 2019 and 2020. Valuable inputs were provided by national leprosy programme managers, technical agencies, public health and leprosy experts, funding... agencies and persons or members of communities directly affected by leprosy.
The Strategy aims to contribute to achieving the Sustainable Development Goals. It is structured along four pillars:
(i) implement integrated, country-owned zero leprosy road maps in all endemic countries;
(ii) scale up leprosy prevention alongside integrated active case detection;
(iii) manage leprosy and its complications and prevent new disability; and
(iv) combat stigma and ensure human rights are respected. Interruption of transmission and elimination of disease are at the core of the Strategy.

WHO convened the fifth stakeholders meeting on the elimination of HAT due to infection with Trypanosoma brucei gambiense (g-HAT) and Trypanosoma brucei rhodesiense (r-HAT) in Geneva, Switzerland, on 7–9 June 2023. The meeting was held again in person after the coronavirus disease (COVID-19) pandem...ic and jointly for both forms of the disease. The previous meetings on g-HAT held in 2014, 2016 and 2018, as well as on r-HAT in 2015, 2017 and 2019, and jointly for g-HAT and r-HAT in 2021 (8) reinforced the partnership and commitment for HAT elimination and structured the mechanisms of collaboration within the WHO network for HAT elimination. The network includes NSSCPs, groups developing new tools, international and nongovernmental organizations involved in disease control, and donors.
Fewer than 1000 cases of HAT annually have been reported over the past 5 years, which is a historic achievement. The area at risk has been substantially reduced. The elimination of HAT as a public health problem at the global level has been achieved.
The new road map for neglected tropical diseases (NTDs) 2021−2030 (“the road map”) with the target to interrupt the transmission of g-HAT requires the strengthened and sustained efforts of all stakeholders, national authorities and partners, under WHO coordination. It will take disproportionally high efforts and innovative strategies to find the last cases of g-HAT and neutralize its transmission. Given the limited resources and other competing public health priorities, this is a challenge that requires our joint commitment.

This toolkit is a comprehensive set of practical tools and resources designed to support country-level risk communication and community engagement (RCCE) practitioners, decision-makers, and partners to plan and implement readiness and response activities for dengue fever outbreaks. The toolkit conta...ins: information about dengue fever; RCCE considerations for how to approach key issues during dengue fever outbreaks; tools for understanding the context in which dengue fever outbreaks occur; methods for collecting data to inform strategy development and bring evidence into planning and implementation of activities; guidance to support vector control and prevention activities; case studies; and links to existing RCCE tools and training. It is one of a suite of toolkits on RCCE readiness and response to a range of disease and response areas.

ver the past 15 years, dengue fever, an endemic disease in the country, has triggered significant epidemics in 2010, 2019, and most recently in 2023. This year, due to the escalating number of reported cases, the Secretariat of Health (SESAL) issued an epidemiological alert in February. By March, th...e incidence of cases had escalated to epidemic proportions.

Snake-bites are well-known medical emergencies in many parts of the world, especially in rural areas. Agricultural workers and children are the most affected. The incidence of snake-bite mortality is particularly high in South-East Asia. Rational use of snake anti-venom can substantially reduce mort...ality and morbidity due to snake bites. These Guidelines are a revised and updated version of similar guidelines published by the WHO Regional Office in South-East Asia in 1999. These guidelines aim to promote the rational management of snake-bite cases in various health facilities where trained health functionaries and quality snake antivenom are available.
