OBJECTIVETo understand the current epidemic situation and high risk factors of human immunodeficiency virus (HIV) infection among paid blood donors living in Shandong provincial China Comprehensive Response (CARES) Project Areas.
METHODSAll residents between 20 to 60 years old were selected from one or several counties in August 2003.
RESULTSThere were 19 HIV(+) infections among 661 subjects interviewed. HIV prevalence rate among paid blood donors was higher (3.98%) than that of others (0.48%) while HIV prevalence rate was higher in plasma donors (7.24%) than that in both plasma and full blood donors (2.90%). There was no infections identified in full blood donors. Donors who donated blood during 1994 - 1995 had a higher prevalence rate (7.07%) than those who started donation after 1995 and those began donation before 1993 (0.99%). The rate of condom use was lower among paid blood donors (13.72%) than that of others. There was a lower rate of voluntary HIV testing among paid blood donors than that of others.
CONCLUSIONThe main high risk population of HIV infection were paid donors in CARES Project Areas, whose risk factor was plasma donation and were infected mainly before 1995. Both the rate of condom use and HIV testing were all very low, indicating that they knew little on HIV/AIDS and paid less attention to self-proctection. It is necessary to enhance HIV/AIDS health education and behavior intervention on paid blood donors.

BACKGROUND: Domestic animals are known to be either maintenance or accidental hosts of Leptospira. Determination of seroprevalence of leptospirosis among these animals is of great importance due to their close association with humans, economic loss as well as the public and veterinary health problems caused by the said zoonosis.
OBJECTIVE: This study aimed to determine the seroprevalence of leptospirosis among water buffaloes, pigs, and dogs in selected areas in the Philippines.
METHODS: Microscopic agglutination test (MAT) was used to test for leptospirosis. Testing was done from January 2007 to August 2008.
RESULTS: With the cut-off titer set at 1:80, the MAT-positivity rates were 82%, 67%, and 79% for 190 water buffaloes, 45 pigs, and 106 dogs, respectively. The most common prevailing serovars detected were Hardjo, Tarassovi, and Hebdomadis for water buffaloes; Semaranga, Grippotyphosa, and Patoc for pigs; and, Manilae, Patoc, and Autumnalis for dogs. MAT-positivity rates among these animals in terms of age (except for water buffaloes), sex and sample collection sites were not statistically significant. No Leptospira was isolated from the blood, urine, and kidney samples of these animals.
CONCLUSION: Results indicate a high seroprevalence of leptospirosis among the animals studied and that several pathogenic leptospires are causing infection in these animals.
