L'Institut de recherche sur les maladies infectieuses de l'Armée américaine a publié en 2011 que certaines catégories de virus, dont l'Ebola, peuvent être transmis sans contact avec des fluides corporels

On page 177 of the handbook, in a chapter discussing “Viral Hemorrhagic Fever” (VHF), a category of viruses that includes Ebola, USAMRID says: “In several instances, secondary infections among contacts and medical personnel without direct body fluid exposure have been documented. These instances have prompted concern of a rare phenomenon of aerosol transmission of infection.”

Page 177 continues to specify: “Therefore, when VHF is suspected, additional infection control measures are indicated.”
