BACKGROUND Elimination of onchocerciasis (river blindness) through mass administration of ivermectin in the six countries in Latin America where it is endemic is considered feasible due to the relatively small size and geographic isolation of endemic foci. We evaluated whether transmission of onchocerciasis has been interrupted in the endemic focus of(More)
In Latin America, onchocerciasis is targeted for elimination by 2012 through twice-yearly mass treatment of the eligible population with ivermectin. In Guatemala, two of the four historical endemic foci have demonstrated elimination of transmission, following World Health Organization guidelines. Using established guidelines ophthalmological, serological,(More)
Newtonian limit of the singular f (R) gravity in the Palatini formalism. Abstract Recently D. Vollick [Phys. Rev. D68, 063510 (2003)] has shown that the inclusion of the 1/R curvature terms in the gravitational action and the use of the Palatini formalism offer an alternative explanation for cosmological acceleration. In this work we show not only that this(More)
Using the continuity of the scalar Ψ 2 (the mass aspect) at null infinity through i o we show that the space of radiative solutions of general relativity can be thought of a fibered space where the value of Ψ 2 at i o plays the role of the base space. We also show that the restriction of the available symplectic form to each " fiber " is degenerate. By(More)
Serotype 3 is one of the most often detected pneumococcal serotypes in adults and it is associated with serious disease. In contrast, the isolation of serotype 3 by bacterial culture is unusual in children with invasive pneumococcal disease (IPD). The purpose of this study was to learn the serotype distribution of IPD, including culture-negative episodes,(More)
The objective of this paper was to develop a prognostic index for severe complications among hospitalized patients with influenza A (H1N1) 2009 virus infection. We conducted a prospective observational cohort study of 618 inpatients with 2009 H1N1 virus infection admitted to 36 Spanish hospitals between July 2009 and February 2010. Risk factors evaluated(More)
The purpose of this study was to evaluate the cost-effectiveness of the strategy of controlling the contacts of tuberculosis patients with latent tuberculosis infection by means of treatment with rifampin for 4 months or isoniazid for 9 months. The cost was the sum of the cost of treating latent tuberculosis infection in all contacts plus the cost of(More)
In 2000, the circulation of indigenous measles was interrupted in Catalonia as a result of the activities of the elimination programme introduced in 1991. However, various transmission chains occurred in the indigenous population after the introduction of an imported case, and this caused a total change in the existing situation of elimination. The(More)
