Airborne Infectious Diseases

Indoor Airborne Bio Aerosols in Valiasr Hospital in Zanjan, Iran

Background: Bio aerosols include airborne micro-organisms such as bacteria, fungi, viruses, etc and their products. Exposure to a bio aerosol is linked with a broad spectrum of health problems, including infectious diseases, acute toxic effects, allergies, and cancer. The aim of this study was to evaluate the quality and quantity of bio aerosols found in the air of different wards in Valiasr Ho...

Wells-Riley & HVAC Filtration for infectious airborne aerosols NAFA Foundation Report HVAC filtration and the Wells-Riley approach to assessing risks of infectious airborne diseases

Measurement of airborne influenza virus in a hospital emergency department.

Size-fractionated aerosol particles were collected in a hospital emergency department to test for airborne influenza virus. Using real-time polymerase chain reaction, we confirmed the presence of airborne influenza virus and found that 53% of detectable influenza virus particles were within the respirable aerosol fraction. Our results provide evidence that influenza virus may spread through the...

Airborne Endotoxins and Airborne Gram-negative Bacteria in Chinese Rabbit Houses

Global rabbit production is currently estimated at more than 1 million tones per year, according to the FAO. The world’s largest producer is China with 315.000 tones in 2000 (FAO, 2001). One major problem in rabbit meat production is infectious diseases of the respiratory tract. Usually respiratory infections are due to an association of non-specific contributing causes with infectious agents. ...

Aerobiology and Its Role in the Transmission of Infectious Diseases

Aerobiology plays a fundamental role in the transmission of infectious diseases. As infectious disease and infection control practitioners continue employing contemporary techniques (e.g., computational fluid dynamics to study particle flow, polymerase chain reaction methodologies to quantify particle concentrations in various settings, and epidemiology to track the spread of disease), the cent...

Airborne infectious diseases during infancy and mortality in later life in southern Sweden, 1766-1894.

BACKGROUND The importance of early life conditions and current conditions for mortality in later life was assessed using historical data from four rural parishes in southern Sweden. Both demographic and economic data are valid. METHODS Longitudinal demographic and socioeconomic data for individuals and household socioeconomic data from parish registers were combined with local area data on fo...
