In 1983 the countries of the Americas, with the technical
cooperation of the Pan American Health Organization
(PAHO), pledged to eliminate human rabies transmitted by
dogs.
1
Since then, countries have made great efforts to elimi-
nate this disease, with notable success, within the framework
of the Regional Program of Elimination of Human Rabies. The
success achieved during the last 30 years and the historical
solidarity between countries in the region support the goal
of elimination of dog-transmitted rabies in the American conti-
nent by 2015. As this date approaches, there is a need to reflect
and reassess the current plan of rabies elimination. This work
briefly describes the achievements of the Regional Program
and the proposed new Regional Action Plan for the elimination
of dog-transmitted rabies.
The technical support for the Regional Program for Elimina-
tion of Human Rabies is founded on the resolutions of the Meet-
ing of Directors of the National Rabies Control Program in the
Americas (Reunio ´ n de Directores de los Programas Nacionales
de Control de Rabia en Ame ´ rica Latina-REDIPRA). Approxi-
mately every 2 years, PAHO convenes the REDIPRA, during
which the countries present and discuss the epidemiological situ-
ation with regard to rabies and strategies for prevention. The
conclusions and recommendations of the REDIPRA are submit-
ted for consideration and approval by the Ministers of Health
and Agriculture of PAHO member states during the Inter-
American Meeting at the Ministerial Level of Health and Agri-
culture (Reunio ´ n Interamericana a Nivel Ministerial en Salud y
Agricultura-RIMSA). Inter-sectorial policies relating to the
rabies elimination program are discussed within the RIMSA to
be submitted later to the PAHO Directive Council.
There have been strong political mandates and international
commitments for the elimination of human rabies transmitted
by dogs in the Americas since 1983.

In 2009, the PAHO
Directive Council, by resolution CD 49.R19,
3
called the coun-
tries of the Americas to commit to the elimination or reduction
of neglected diseases and other poverty-related diseases includ-
ing the elimination of dog-transmitted rabies by 2015.

Since the implementation of the Regional Program, the
number of human cases has decreased by ~95% (from 355 cases
in 1982 to 10 cases in 2012).
5
In dogs, the reduction has been
of 98% (from 25,000 cases in 1980 to fewer than 400 in 2010).
5
Much of this success has been a result of the application of dog
vaccine and the strong cooperation between health and agri-
culture sectors of member countries, and the collaboration
of regional agencies, international, public, private, and non-
governmental organizations.

The Regional Rabies Program
has been considered since its inception as an intersectoral ini-
tiative within the framework of One Health, where epidemio-
logical surveillance includes cases in humans, domestic animals,
animals of economic interest, and wildlife.
Today, most parts of the Americas have already eliminated
the circulation of rabies virus in canine populations.

Cases of
human rabies transmitted by dogs in the region are circumscribed
to a small number of well-defined areas
9
(Figure 1). Of the
570 first administrative level sub-units (province, state, or depart-
ment) in Latin America, only 11 units (2%) reported cases of
human rabies transmitted by dogs in the last 4 years. These cases
are concentrated in areas of the periphery of big cities, neglected
communities, or international border areas where the popula-
tion has little information about the risks of the disease, limited
access to quality health services and poor living standards
or working conditions. These areas are also characterized by
having a high proportion of unvaccinated dogs
10
and of limited
availability or accessibility to immunobiological products for
pre- or post-exposure prophylaxis.

The elimination of these pockets of disease depends on the
local implementation of proven control plans, widespread
participation of the population, and the technical cooperation
between countries.
As commonly seen in control efforts for other diseases, the
reduction of the number of cases of human rabies transmitted
by dogs has led to a parallel decline in the attention given to
the disease by institutions and health departments. Even for
endemic areas within countries, the competitive allocation
of scarce funds to other priorities at the national level can
result in the allocation of fewer resources for the fight against
rabies at lower administrative levels. As a result, institutional
memory and awareness among the population might be lost.
PAHO has prioritized technical cooperation for the imple-
mentation of the Regional Program on four pillars of action:
attention to populations at risk, canine rabies vaccination, sur-
veillance, and training and communication. Care for people at
risk of infection is based on ensuring universal access to pre- and
post-exposure prophylaxis and decentralization of health care to
secure access. The effective distribution of post-exposure pro-
phylaxis to all people exposed to rabies is a logistical challenge,
especially given the marginalization of populations currently
affected. Canine rabies vaccination has been used successfully
as a cost effective approach with over 40 million dogs vaccinated
every year in the Americas. However, enzootic areas fail to
