AIRBORNE INFECTION — TRANSMISSION AND CONTROL

Trachoma: transmission, infection, and control.

Mass antibiotic treatment and facial cleanliness are central to WHO's strategy for the elimination of blindness caused by trachoma. Recent studies have highlighted the heterogeneous response of communities to mass treatment and the complex relation between infection with Chlamydia trachomatis and clinical disease. It is important to be able to explain these findings to predict and maximise the ...

Airborne infection control in healthcare settings

Exposure of human beings to different airborne pathogens has resulted in the emergence of epidemics of respiratory infections. This airborne transmission becomes even more prevalent in healthcare settings because of overburdened hospitals and the presence of immunosuppressed patients. Airborne infection control measures include a three-pronged approach, namely administrative control, environmen...

Airborne transmission of communicable infection--the elusive pathway.

Some aspects of the airborne transmission of infection.

The relationship between the human body and the dissemination of potentially pathogenic particles and droplets is described. Airborne transmission of infection in operating theatres and a burns unit and the part played by the human microclimate and its interaction with ventilating air flows is discussed. The mechanisms by which different garment assemblies used for surgery can enhance particle ...

Engineering control of airborne disease transmission in animal laboratories.

We here present a review of the problem of controlling airborne disease transmission in animal research facilities, with emphasis on engineering design and air-treatment technologies. Dilution ventilation, pressurization control, source control, and air disinfection and removal systems are reviewed, and analytical studies on the effects of dilution ventilation, filtration, and ultraviolet germi...
