Water, sanitation and hygiene (WASH) are critical in the prevention and care for all of the 17 neglected tropical diseases (NTDs) scheduled for intensified control or elimination by 2020.
Provision of safe water, sanitation and hygiene is one of the five key interventions within the global NTD ...roadmap. Yet to date, the WASH component of the strategy has received little attention and the potential to link efforts on WASH and NTDs has been largely untapped.
Focused efforts on WASH are urgently needed if the global NTD roadmap targets are to be met. This is especially needed for NTDs where transmission is most closely linked to poor WASH conditions such as soil-transmitted helminthiasis, schistosomiasis, trachoma and lymphatic filariasis.
This strategy aims to mobilise WASH and NTD actors to work together towards the roadmap targets.

Testing and diagnosis of hepatitis B (HBV) and C (HCV) infection is the gateway for access to both prevention and treatment services, and is a crucial component of an effective response to the hepatitis epidemic. Early identification of persons with chronic HBV or HCV infection enables them to recei...ve the necessary care and treatment to prevent or delay progression of liver disease. Testing also provides an opportunity to link people to interventions to reduce transmission, through counselling on risk behaviours and provision of prevention commodities (such as sterile needles and syringes) and hepatitis B vaccination.

Recent systematic reviews and meta-analysis of the impact of chemical-based mollusciciding (King et al., 2015, Sokolow et al., 2016) have concluded that regular mollusciciding is likely to contribute significantly towards elimination of schistosomiasis in high-risk areas. The WHO roadmap’s new foc...us on “transmission control, wherever possible” (WHO, 2012a) reinforces the need to promote intermediate-host snail control to prevent schistosomiasis transmission.
This operational manual is intended to facilitate the reintroduction of practices and protocols for use of molluscicides in the field in schistosomiasis control programmes. It is complemented by guidelines on the laboratory and field testing of the efficacy of molluscicides for schistosomiasis control (WHO, 2017 [in preparation]).

This policy brief has been developed in response to the contemporary challenge of antibiotic resistance (ABR). ABR poses a formidable threat to global health and sustainable development. It is now increasingly recognized that the systematic neglect of cultural factors is one of the biggest obs...tacles to achieving better health outcomes and better standards of living worldwide. Using a cultural contexts of health approach, the policy brief explores the centrality of culture to the challenge of ABR. The brief examines how the prescription and use of antibacterial medicines, the transmission of resistance, and the regulation and funding of research are influenced by cultural, social and commercial, as well as biological and technological factors. The brief moves beyond the ready equation of culture with individual behaviours and demonstrates how culture serve as an enabler of health and provide new possibilities for change.

La prevención de un brote de una enfermedad prevenible mediante vacunación no solo salva vidas, sino que requiere menos recursosque la respuesta al brote y ayuda a reducir la carga que supone para los sistemas de salud, los cuales ya están sometidos a una fuerte presión por la pandemia de COVID-19. En sus esfuerzos por mantener los sistemas de inmunización, los países deben adoptar enfoques que respeten el principio de «no hacer daño» y limiten la transmisión de la COVID-19 durante la realización de actividades de inmunización. Las visitas para la administración de vacunas también pueden ser una ocasión para divulgar mensajes que fomenten comportamientos que reducen el riesgo de transmisión del virus de la COVID-19 y para proporcionar orientaciones sobre las medidas que deben adoptarse si se observan síntomas.

There is a broad consensus nowadays that the Earth is warming up as a result of greenhouse gas emissions caused by anthropogenic activities. It is also clear that current trends in the fields of energy, development and population growth will lead to continuous and ever more dramatic climate change. ...This is bound to affect the fundamental prerequisites for maintaining good health: clean air and water, sufficient food and adequate housing. The planet will warm up gradually, but the consequences of the extreme weather conditions such as frequent
storms, floods, droughts and heat-waves will have sudden onset and acute repercussions. It is widely accepted that climate change will have an impact on the spread of infectious diseases in Europe, which is likely to bring about new public health risks in the majority of cases. Transmission of infectious diseases depends on a number of factors, including climate and environmental elements. Foodborne and waterborne diseases, for instance, are associated with high temperatures. Disease-transmitting vectors (e.g. mosquitoes, sandflies and ticks) are highly sensitive to climate conditions, including temperature and humidity; their geographical distribution will widen as climate conditions change, potentially allowing them to spread into regions where they are not currently able to live.
The primary purpose of this manual on climate change and infectious diseases is to raise the awareness and the level of knowledge of health workers at national, regional and local levels in the former Yugoslav Republic of Macedonia on the health risks associated with climate change and infectious diseases. This manual was devel-
oped as part of the WHO Regional Office for Europe project, Protecting health from climate change: a seven–country initiative, implemented with financial support from the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety.

Epidemiology
Chagas disease (American trypanosomiasis) is caused by the protozoan parasite Trypanosoma cruzi, and transmitted to humans by infected triatomine bugs, and less commonly by transfusion, organ transplant, from mother to infant, and in rare instances, by ingestion of contaminated food or... drink.1-4 The hematophagous triatomine vectors defecate during or immediately after feeding on a person. The parasite is present in large numbers in the feces of infected bugs, and enters the human body through the bite wound, or through the intact conjunctiva or other mucous membrane.
Vector-borne transmission occurs only in the Americas, where an estimated 8 to 10 million people have Chagas disease.5 Historically, transmission occurred largely in rural areas in Latin America, where houses built of mud brick are vulnerable to colonization by the triatomine vectors.4 In such areas, Chagas disease usually is acquired in childhood. In the last several decades, successful vector control programs have substantially decreased transmission rates in much of Latin America, and large-scale migration has brought infected individuals to cities both within and outside of Latin America.

Chagas disease (CD) is endemic in the Americas, being present in 21 countries, where it affects about 6 million
people.(1) With such relevant numbers of people affected and disability adjusted life years lost, CD is a poverty-related
and poverty-promoting disease.
Although data describe a relevan...t ongoing public health problem for the American continent, significant results
in the interruption of transmission has been achieved by coordinated multi-country programs. In particular, the
Southern Cone Initiative (SCI), officially formalised in November 1991 by the Ministers of Health of Argentina, Brazil, Bolivia, Chile, Paraguay and Uruguay, has shown how a well-designed control program can significantly reduce
CD transmission.(2) Before this initiative, in these countries, there were 11 million infected persons and 50 million at
risk, 62% of the infected individuals of the whole continent.

Chagas disease (CD) is caused by the parasite Trypanosoma cruzi, and it is endemic in Central, South America, Mexico and the
South of the United States. It is an important cause of early mortality and morbidity, and it is associated with poverty and stigma. A third of
the cases evolve into chronic... cardiomyopathy and gastrointestinal disease. The infection is transmitted vertically and by blood/organ
donation and can reactivate with immunosuppression. Case identification requires awareness and screening programmes targeting the
population at risk (women in reproductive age, donors, immunocompromised patients). Treatment with benznidazole or nifurtimox is most
effective in the acute phase and prevents progression to chronic phase when given to children. Treating women antenatally reduces but does
not eliminate vertical transmission. Treatment is poorly tolerated, contraindicated during pregnancy, and has little effect modifying the
disease in the chronic phase. Screening is easily performed with serology. Migration has brought the disease outside of the endemic
countries, where the transmission continues vertically and via blood and tissue/organ donations. There are more than 32 million migrants
from Latin America living in non-endemic countries. However, the infection is massively underdiagnosed in this setting due to the lack of
awareness by patients, health authorities and professionals. Blood and tissue donation screening policies have significantly reduced
transmission in endemic countries but are not universally established in the non-endemic setting. Antenatal screening is not commonly
done. Other challenges include difficulties accessing and retaining patients in the healthcare system and lack of specific funding for the
interventions. Any strategy must be accompanied by education and awareness campaigns directed to patients, professionals and policy
makers. The involvement of patients and their communities is central and key for success and must be sought early and actively. This review
proposes strategies to address challenges faced by non-endemic countries

Leptospirosis is a zoonotic disease with epidemic potential, especially after a heavy rainfall,
caused by a bacterium called Leptospira. Leptospira interrogans is pathogenic to humans and
animals, with more than 200 serologic variants or serovars. Humans usually acquire
leptospirosis through dire...ct contact with the urine of infected animals or a urine-contaminated
environment. Human-to-human transmission occurs only very rarely. Leptospirosis may present
with a wide variety of clinical manifestations, from a mild illness that may progress to a serious
and sometimes fatal disease. Its symptoms may mimic many diseases, such as influenza,
dengue and other viral haemorrhagic diseases; making the correct diagnosis (clinical and
laboratory) at the onset of symptoms is important to prevent severe cases and save lives,
primarily in outbreak situations.

Leptospirosis is an infectious disease caused by pathogenic organisms belonging to the genus Leptospira, that are transmitted directly or indirectly from animals to humans. Leptospirosis is a major direct zoonosis. Humanto-human transmission occurs only very rarely.
Since the last situation report on the multi-country outbreak of cholera was published on 1 June 2023 (covering data reported until 15 of May), no new country reported a cholera outbreak. In total, 24 countries have reported cases since the beginning of 2023. The WHO African Region remains the most ...affected region with 14 countries reporting cholera cases since the beginning of the year. The overall capacity to respond to the multiple and simultaneous outbreaks continues to be strained due to the global lack of resources, including shortages of the Oral Cholera Vaccine (OCV) and cholera supplies, as well as overstretched public health and medical personnel, who are dealing with multiple parallel disease outbreaks and other health emergencies. Based on the large number of outbreaks and their geographic expansion, as well as a lack of vaccines and other resources, WHO continues to assess the risk at global level as very high.

Infection prevention and control (IPC) in a CTC/ CTU IPC are all practical measures taken in the healthcare facility to prevent harm caused by infections to patients, health workers and communities.
The main goal of IPC in the cholera response is to
• To reduce transmission of health care-as...sociated infections of cholera and any other infectious disease
• To enhance the safety of staff, patients and visitors
• To enhance the ability of the organization/health care facility to respond to an outbreak
• To reduce the risk of the hospital (health care facility) itself amplifying the outbreak
Water, Sanitation and Hygiene (WASH)
WASH are all measures taken to guarantee environmental hygiene, safe water of all used within the health facility. It encompasses water, sanitation, waste management, cleaning within the health facility which in this case is CTU/C. A complete WASH package in the CTU/CTC reduces the risk of spread of Vibrio cholerae inside and outside the CTC/CTU.
The probability of spreading or acquiring cholera through a CTC/CTU can be highly reduced when proper IPC and WASH measures are respected, followed and monitored. These measures are, in principle, valid in CTC/CTUs and ORPs, although they need to be adapted to the specific characteristics of the facility concerned.
