Abstract: the h5n1 avian influenza virus has been spreading fast over countries and continents in the last years, with a real possibility of reaching brazil. the scope of this paper is to analyze the impacts of three different scenarios of a possible bird flu outbreak in commercial poultry production in brazil, with the aid of a brazilian inter-regional general equilibrium model. results point to a greater negative impact over the production in the southern region, with the correspondent negative impact in the broad regional economies. regions producing substitute goods, on the other hand, would be benefited, due to consumer's substitution towards other meats. actually, the substitution effect caused by the change in consumer's preferences, both domestically and abroad, is found to be the key driver of the regional income and employment changes.

Nascimento, Luiz Fernando C.;
Cadernos de Saúde Pública , 2004, DOI: 10.1590/S0102-311X2004000600036
Abstract: this study aims to describe childhood tuberculosis incidence in southeast brazil in 1996. it is a descriptive study based on secondary records from the tuberculosis division of the s?o paulo state health department. the study area includes 40 cities, has some 1,800,000 inhabitants, and is located between s?o paulo and rio de janeiro, the largest cities in brazil. the study included cases up to 15 years of age. independent variables were: sex, age, type of case, clinical presentation, radiology, afb microscopy, hiv antibody tests, and method of discovery. the incidence rate in this age bracket was 10.4/100,000. pulmonary manifestations were the most common, and control of contacts was the most common method of case discovery. afb microscopy was performed in 18.6% of the cases and hiv testing was done in 14.9%. incidence in this study was higher than for the state of s?o paulo as a whole. poor socioeconomic level, deterioration of public health services, treatment dropout by adults and their persistence as sputum-positive carriers, and flaws in case reporting and follow-up could explain these results.
