The effect of relative humidity (RH) on the airborne stability of two small bacterial viruses, S-
13 and MS-2, was studied. Poorest recovery of S-13 was obtained at 50% RH …

Adults experience an average of one to three and children two to seven respiratory illnesses …

Highlights•Respiratory viruses are transmitted via contact, droplets or aerosols.•Most studies
on inter-human transmission routes are inconclusive.•The relative importance of respiratory …

Studies with artificially prepared small-particle aerosols were undertaken to provide better
con-trol of the site of inoculation than was possible with liquid suspensions instilled into the …

Numerous viruses of human or animal origin can spread in the environment and infect
people via water and food, mostly through ingestion and occasionally through skin contact …

Viruses pass into the environment from clinically ill or carrier hosts; although they do not
replicate outside living animals or people, they are maintained and transported to …

Objective: The concept of aerosol transmission is developed to resolve limitations in
conventional definitions of airborne and droplet transmission. Methods: The method was …

developed or industrialized countries, infections of the upper and lower respiratory tract are …

The atmospheric dispersion of virus was simulated using a computer model which had been
developed for predicting the dispersion of toxic gases from chemical engineering plants. The …
