. The disease is primarily transmitted through the ingestion of food or water contaminated with the feces of an infected person.
To protect against cholera and other diarrheal diseases, the document emphasizes the importance of drinking safe water, such as bottled water with intact seals, boiled water, or water treated with chlorine products. Frequent handwashing with safe water and soap is recommended, and in the absence of soap, hands can be cleaned using ash or sand followed by rinsing with safe water. Proper sanitation practices, such as using latrines or burying feces and avoiding defecation near water sources, are crucial. The document also highlights safe food practices, including thoroughly cooking food (especially seafood), consuming it while hot, keeping it covered, and peeling fruits and vegetables. Ensuring the safe cleaning of kitchens and areas where the family bathes or washes clothes is also advised.
In case of diarrheal illness, the document stresses the immediate use of oral rehydration solution (ORS) to prevent dehydration and the importance of seeking medical attention as quickly as possible. Patients should continue ORS intake both at home and during transit to a health facility. These preventative measures and prompt treatment strategies are vital for reducing cholera transmission and mortality.

treated. Symptoms range from mild diarrhea to severe dehydration, shock, and death.
Treatment primarily involves Oral Rehydration Therapy (ORT) to replace lost fluids, and in severe cases, intravenous fluids. Antibiotics are generally not recommended for mass treatment. Prevention focuses on safe drinking water, sanitation, hand hygiene, and proper food handling.
The document also discusses cholera vaccination, with three WHO-approved oral vaccines available. However, vaccines should be used alongside other control measures. The Global Task Force on Cholera Control (GTFCC) aims to eliminate cholera transmission in 20 countries by 2030 through improved sanitation, vaccination, and rapid outbreak response.

2 decades. In 2000, the estimated at-risk population in EMR countries was 12.6 million people, accounting for approximately 1% of the global disease burden. Of the 22 EMR countries, 3 countries (Egypt, Sudan and Yemen) were LF endemic and the disease was suspected in 4 other countries (Djibouti, Oman, Somalia and Saudi Arabia). After almost 2 decades of implementing sustained control and prevention measures, Egypt and Yemen were successfully validated by the WHO as having achieved the elimination criteria in 2017 and 2019, respectively. In 2018, Sudan completed mapping of LF, reaching 26.2% geographical coverage where mass drug administration (MDA) is required and is scaling-up MDA. Extensive epidemiological assessment indicated the absence of LF transmission in the four suspected countries and no MDA required. Challenges faced during the elimination and post-elimination phases are described and discussed

h. In 1999, 22 countries and territories in the Pacific joined together and launched the Pacific Programme to Eliminate Lymphatic Filariasis. Shortly after, the Global Programme to Eliminate Lymphatic Filariasis was launched in 2000. In 2004, 12 countries in the Asia subregion of the Western Pacific Region and Southeast Asian Region joined and developed the Mekong-Plus Strategic Plan for Elimination of Lymphatic Filariasis. Since then, significant efforts have been made by all endemic countries, with annual mass drug administration (MDA) as a principal strategy, through strong partnership with the WHO and other donors and partners. As a result, by the end of 2019, 10 of 22 endemic countries in the region, including 8 of 16 countries in the Pacific and 2 countries in the Asia subregion, achieved WHO validation for elimination of lymphatic filariasis (LF) as a public health problem. All the other countries are either progressing with post-MDA surveillance or accelerating efforts by adoption of the new triple drug therapy strategy and enhancement of MDA campaigns to tackle persistent transmission. Some 85% of the originally endemic implementation units have stopped MDA and the number of people requiring MDA for LF in the Western Pacific Region was reduced by 72% from 2000 to 2018. This paper reviews the progress, key success factors and remaining challenges and indicates the way forward to achieve LF elimination in the Western Pacific Region.

evention practices. Dengue continues to disseminate to new areas, including high latitude regions, and a new serotype (dengue virus serotype 5) has been identified. Vaccine research has made new progress, in which the licensed yellow fever and dengue virus quadrivalent chimeric vaccine is now under further safety assessment. In disease surveillance, because of its operational simplicity, rapidity, capability, and utility as an indicator of disease severity, dengue virus NS1 antigen detection has great promotion and application value among primary health care institutions. Vector control progress has driven new breakthroughs in biotechnology, including Wolbachia-infected Aedes and genetically modified Aedes. Both Aedes variants have been used to block transmission of the dengue virus through population replacement and suppression. In the future, vector control should still be pursued as a key measure to prevent transmission, along with anti-viral drug and vaccine research.

After 100 years of chemotherapy with impractical and toxic drugs, an oral cure for human African trypanosomiasis (HAT) is available: Fexinidazole. In this case, we review the history of drug discovery for HAT with special emphasis on the discovery, pre-clinical development, and operational challenge

s of the clinical trials of fexinidazole. The screening of the Drugs for Neglected Diseases initiative (DNDi) HAT-library by the Swiss TPH had singled out fexinidazole, originally developed by Hoechst (now Sanofi), as the most promising of a series of over 800 nitroimidazoles and related molecules. In cell culture, fexinidazole has an IC50 of around 1 µM against Trypanosoma brucei and is more than 100-fold less toxic to mammalian cells. In the mouse model, fexinidazole cures both the first, haemolymphatic, and the second, meningoencephalitic stage of the infection, the latter at 100 mg/kg twice daily for 5 days. In patients, the clinical trials managed by DNDi and supported by Swiss TPH mainly conducted in the Democratic Republic of the Congo demonstrated that oral fexinidazole is safe and effective for use against first- and early second-stage sleeping sickness. Based on the positive opinion issued by the European Medicines Agency in 2018, the WHO has released new interim guidelines for the treatment of HAT including fexinidazole as the new therapy for first-stage and non-severe second-stage sleeping sickness caused by Trypanosoma brucei gambiense (gHAT). This greatly facilitates the diagnosis and treatment algorithm for gHAT, increasing the attainable coverage and paving the way towards the envisaged goal of zero transmission by 2030.

ance & Reporting, Use of Oral Cholera Vaccines (OCV), Healthcare System Strengthening, and Community Engagement.
Ethiopia has historically faced recurrent cholera outbreaks due to poor sanitation, unsafe water, and weak health infrastructure. The plan prioritizes high-risk areas (hotspot woredas) and aims to reduce cholera-related mortality by 90% by 2028. It includes efforts to improve WASH conditions, strengthen disease surveillance, enhance rapid response capabilities, expand vaccination campaigns, and integrate cholera control into broader health policies.
The government, in collaboration with international partners such as WHO, UNICEF, and the Global Task Force for Cholera Control (GTFCC), will implement and monitor the plan. The estimated budget for the initiative is $390 million over eight years. Ethiopia aims to achieve zero cholera transmission in hotspot regions, ensuring sustainable public health improvements.
