RESUMO
Data on the burden of disease from tuberculosis (TB) in Filipino households are limited. To determine the magnitude of undiagnosed TB in TB households, and the demographic and socio-economic factors associated with TB in the Philippines, household contacts of adult smear-positive TB patients seen from July 2001 to June 2003 were assessed based on interview, chest X-ray, tuberculin skin test and sputum examination. History of TB and older age were independently associated with TB disease, and age and duration of cohabitation with TB infection. TB and TB infection are highly prevalent in TB households in the Philippines.

OBJECTIVE: This study was undertaken to determine the seroepidemiology of Hantavirus infection in the Philippines. METHODS: This is a cross-sectional study done in asymptomatic volunteers from various communities in the Philippines selected by a stratified multistage sampling design. Antibody to Hantavirus was detected by particle agglutination (PA) test using Hantadia high-density particle agglutination (HDPA) reagent kit. RESULTS: The prevalence of positive Hantavirus antibody among 461 subjects was the same in both males (6.1%) and females (6.1%) in rural (7.6%), urban (5.6%), and urban poor (5.1%) populations. CONCLUSIONS: The prevalence of Hantavirus infection in the Filipino population is comparable to that seen in other developing countries. The HDPA can be conveniently used as a rapid tool to detect the Hantavirus antibody for seroepidemiologic and diagnostic purposes.
