Since 2010,WHO has published operational guidelines to assist Member States and their
partners in developing national plans to combat NTDs. Programmatic tools to facilitate
integrated planning for, and reporting on, the delivery of preventive chemotherapy – such as
the joint request form for selected medicines, the joint reporting form, the annual workplan
and the epidemiological data reporting form – were introduced in all WHO regions in 2013.
Training modules have been developed, and regional and subregional workshops have been
organized to help programme managers build their capacity to adapt global strategies to their
countries, design and implement interventions, and monitor and evaluate outcomes.
Estimates of the number of people who require preventive chemotherapy are regularly
updated for each disease, based on the most recent epidemiological data generated by
monitoring and evaluation activities of programmes, and on demographic information reflecting
population growth rates. Analyses have been carried out to determine the geographical overlap
of the different diseases targeted by preventive chemotherapy. Table 3.2.1 shows the number
of countries eligible for preventive chemotherapy, the types of infections transmitted in each
country and the number of people requiring at least one intervention.
Although preventive chemotherapy is required in 122 countries, most of the population in
need of treatment is concentrated in a few high-burden countries. Some 10 countries host
approximately 70% of the global population requiring preventive chemotherapy (listed in
order of the number of people requiring treatment): India, Indonesia, Nigeria, Bangladesh, the
Democratic Republic of the Congo, Ethiopia, the United Republic of Tanzania, the Philippines,
Myanmar and Pakistan.
