Malaria prevention in travelers to endemic areas remains dependent principally on chemoprophylaxis. Although malaria chemoprophylaxis refers to all malaria species, a distinction should be drawn between falciparum malaria prophylaxis and the prophylaxis of the relapsing malaria species (vivax & ovale). While the emergence of drug resistant strains, as well as the costs and adverse reactions to ...

On October 15, 2001, a U.S. Senate staff member opened an envelope containing Bacillus anthracis spores. Chemoprophylaxis was promptly initiated and nasal swabs obtained for all persons in the immediate area. An epidemiologic investigation was conducted to define exposure areas and identify persons who should receive prolonged chemoprophylaxis, based on their exposure risk. Persons immediately ...

The clinical and epidemiological characteristics, adverse events, treatment adherence and effectiveness of isoniazid chemoprophylaxis were analyzed in a cohort of 138 tuberculosis/HIV-coinfected patients. An open, non-randomized, pragmatic prophylactic trial was conducted on adult patients with a normal chest X-ray and positive tuberculin skin test (>or= 5 mm) who received isoniazid chemoprophy...

We compared the cost-effectiveness of different strategies for the control and management of influenza for the elderly populations in three European countries (England and Wales, France, Germany). A "no intervention" scenario was compared with six control strategies: opportunistic vaccination (passive recruitment), comprehensive vaccination programmes (active recruitment), 4 weeks chemoprophyla...

We performed a systematic literature review to assess the effectiveness of chemoprophylaxis for contacts of sporadic cases of invasive meningococcal disease (IMD) in educational settings. No studies directly compared IMD risk in contacts with/without chemoprophylaxis. However, compared to the background incidence, an elevated IMD risk was identified in settings without a general recommendation ...

This paper reviews the evidence for beneficial effects of malaria chemoprophylaxis on haematological responses, morbidity, mortality, health service utilization and rebound immunity in children. As anaemia may play an important role in childhood mortality, it is important to assess evidence from controlled trials of the potential of chemoprophylaxis to reduce childhood anaemia. An analysis of t...

Pertussis is well controlled in the UK as a result of an effective vaccination programme. Nevertheless, the disease has not been eliminated, and cases still occur in the most vulnerable group of young infants. Erythromycin chemoprophylaxis has been advocated for use in contacts to prevent secondary cases but the evidence for its use is weak. These guidelines are based on a review of the evidenc...

BACKGROUND An influenza outbreak might result in disruption of services at acute care setting hospitals. OBJECTIVES  In this study, we retrospectively evaluated the use of neuraminidase inhibitor chemoprophylaxis for prevention of nosocomial spread of influenza in a university hospital. PATIENTS/METHODS During the 3-year study period, 202 index cases of influenza [30 hospitalized patients a...

A tuberculosis model which incorporates treatment of infectives and chemoprophylaxis is considered. For this model, controls on treatment, chemoprophylaxis and disease relapse are incorporated to reduce the latently infected and actively infected individual populations, via application of the Pontryagins Maximum Principle of optimal control theory.

STUDY OBJECTIVE The aim was to audit, against agreed standards, the control of bacterial meningitis, in particular completeness of notification and appropriateness of distribution of chemoprophylaxis to contacts; and to implement appropriate changes and monitor their impact. DESIGN The first phase involved determination, for the years 1983 and 1984, of completeness of notification by comparis...
