This practical guideline establishes definitions for “contact”, “contact person”, “contact tracing” and other associated concepts. It allows for improvement of contact tracing strategies and provides recommendations attempting to answer some, though not all, questions that arose during t...he 2019 coronavirus pandemic and other outbreaks. The use of this guideline begins once people have been diagnosed and the potential for transmission exists. It is not, however, intended to assist with case investigation. The guideline empowers health workers, governments, and public health officials with the tools to implement effective contact tracing strategies.

Almost half of the world's population, about 4 billion people, live in areas with a risk of dengue. Anyone who lives in or travels to an area with risk of dengue is at risk for infection.Before you travel, find country-specific travel information to help you plan and pack.
Schistosomiasis is a chronic parasitic infection caused by worms. It is most common in rural and impoverished populations. In the Americas, the parasite species is Schistosoma mansoni, which is associated with intestinal schistosomiasis. The main risk factor for infection is exposure through househo...ld, work, or recreational activities in fresh water contaminated with faeces from infected humans. In the Region, for transmission to occur, Biomphalaria snails, the intermediate hosts of the parasite, must also be present in contaminated water. Children and adolescents are the populations most at risk

This template dossier complements and should be used after fulfilling the criteria and preconditions specified in the Process of validation of elimination of kala-azar as a public health problem in South-East Asia. The national kala-azar programme should be in the consolidation phase of elimination;... that is, the annual incidence of kala-azar in the implementation unit is maintained below 1 case (new plus relapse) per 10 000 population for a minimum of 3 consecutive years.
The template is designed to help national kala-azar elimination programmes prepare a dossier documenting the essential evidence supporting the request to the World Health Organization (WHO) to validate the status of kala-azar elimination as a public health problem in their country. The information presented in this document will help independent assessors understand the national programme’s specific context, achievements and relevant epidemiological data.
The dossier should be organized according to the following sections:
- Description of the country context and health system capabilities
- Historical data and delineation of endemic areas
- Surveillance and elimination activities
- Epidemiological data
- Vector control strategy and activities
- Post-validation surveillance plan
Once the dossier is prepared, it should be examined and duly endorsed by the National Task Force on kala-azar elimination and/or neglected tropical diseases, or a similar body, before submission to WHO.
