Background: Despite an effective vaccine, 60,000 new HBV infections were reported in the US in 2004; 95% in adults. We evaluate HBV sero-prevalence, risk behaviors and self-reported vaccination among Latino immigrant, Asian immigrant and US born low income men in five northern California counties.

Methods: Population based, cross sectional survey of HBV sero-prevalence and risk behaviors in men aged 18 to 35 years.

Results: Among 1,512 men screened, Asian immigrants were most likely to have had prior HBV infection (15.1%) and chronic infection (3.8%) compared to US born (prior 5.1%, chronic 0.6%) and Latino immigrant men (prior 2.0%, chronic 0.3%.) Reported HBV vaccination was lowest for Latino immigrants (12%) compared to Asian immigrants and US born men (35% in both.) Latino immigrants reported less educational attainment, medical insurance coverage and access to a physician in the last six months.

Discussion: Healthcare providers should routinely screen Asian immigrants for HBV regardless of their self reported vaccination status. Latino immigrants may comprise an important group of under-vaccinated, at risk persons in California. HBV testing and vaccination of immigrants soon after US arrival should be encouraged.

The ANRS-Coquelicot survey has been carried out in France for 25 years, to monitor trends in infectious diseases (HIV and hepatitis B and C) among people who use drugs. In this article, we propose to open the black box of this monitoring experience, by describing and analysing some methodological, ethical and political issues involved in this type of survey. The ANRS-Coquelicot survey has carried out on five occasions in France (from 2002 to 2024) in several cities (from 1 to 27) among people who use drugs recruited in a large diversity of services including drug treatment centres, harm reduction facilities, residential services as well as outreach teams.

Background And Objective: Brucellosis is a neglected zoonotic disease caused by Brucella species. Unlike most developed nations, the problem of brucellosis in Ethiopia remains a public and animal health concern. This study was conducted to determine the magnitude of brucellosis in animals (mainly cattle, sheep, goats, dogs and camels) and humans, and to identify the risk factors for human brucellosis.

Background: Brucellosis is a neglected zoonotic disease often contracted through contact with animals and consumption of unpasteurized dairy products. Despite being the most common cause of non-malarial acute febrile illness brucellosis is often misdiagnosed in healthcare setups. The global incidence of Brucella infection is reported to be over 2 million cases annually.

Article Synopsis
  • - Contagious bovine pleuropneumonia (CBPP), caused by Mycoplasma mycoides, is a serious respiratory disease that threatens cattle health and livestock productivity in Ethiopia, with a pooled prevalence of 13% based on 23 studies covering over 52,000 cattle.
  • - The study revealed significant geographic variations in CBPP prevalence, with the highest rates found in the eastern (18%) and western (15%) regions, and highlighted that post-2016, prevalence rates rose to 16% compared to 8% before that year.
  • - Factors such as herd size, body condition of cattle, and the location of the study were found to significantly influence CBPP prevalence, indicating a

Article Synopsis
  • Hepatitis B Virus (HBV) during pregnancy significantly increases the risk of chronic infections in newborns and can lead to severe liver complications later in life.
  • A case-control study in Southwest Ethiopia investigated the factors influencing HBV infection rates among pregnant women, analyzing data from 228 participants.
  • Key risk factors for HBV included lack of education, urban living, history of unsafe abortion, sharing sharp tools, family contact with infected individuals, tribal scarification practices, and unsafe tooth extraction.
