Demonstration Project on Health Care Worker Protection Against Hepatitis B in Kalulushi District

Hepatitis B virus (HBV) has infected over one third of the world's population; of these about 350 million go on to be chronic carriers. Infection with HBV can be self-limiting depending on age and immunity status of the infected person. Acute infection with HBV is cleared within six months of initial infection while chronic infection can last longer than six months. HBV can be transmitted perinatally, sexually, horizontally, through direct contact with infectious body fluids or blood, being pricked with an infected needle and injury from instruments contaminated with infectious body fluid or blood. Certain population groups are at higher risk of infection with HBV. Among these populations is that of health care workers (HCWs). In this population, HBV infection can occur through occupational exposure. In fact, the hepatitis B virus is more contagious than human immunodeficiency virus (HIV) during a needle stick injury (30% versus 0.5%). It is therefore imperative that HCWs are highly knowledgeable about HBV and how they can prevent transmission. Protection from HBV infection can be achieved by means of vaccination after which the HBV vaccine has been shown to be 90-100% effective.

Water Hygiene Versus Waterless Hygiene Technology for Totally Dependent Hospitalized Patients

The aim of this randomized controlled trial is to verify whether the efficacy of perineal hygiene procedures performed in dependent patients admitted to medical or geriatric wards with pre-moistened wipes without water is higher than that found after procedures performed with disposable hand grips, soap, and water.

Prevalence of Latent Tuberculosis Infection in Health-care Workers and Students

This study is a cross-sectional study that examines the prevalence of Latent Tuberculosis Infection \[LTBI\], defined as individuals infected with Mycobacterium tuberculosis with no clinical evidence of disease, and the possible risk factors of LTBI in a large cohort of health care workers (HCWs) and students.
