The means by which Ebola virus transmits through direct contact with body fluids of infected individuals is well covered in scientific literature. But little is known about the life the virus has - if any - outside the body. For example, does Ebola remain active on glass surfaces and countertops? Does it persist in sewage and wastewater systems?
Such questions are rarely addressed in currently published literature, say engineers from the University of Pittsburgh (Pitt) and Drexel University, Philadelphia.
A team of engineers says scientific literature contains little information about how well Ebola survives outside the body. They call for research to investigate its persistence in the environment so correct guidance can be given on disinfection and waste handling.
They report their findings - or lack of them - and why it is important to find some answers, in a paper published in the journal Environmental Science & Technology Letters....
The size and scale of the epidemic have raised significant unanswered questions for the scientific and engineering communities, as well as the general public - questions about "Ebola virus persistence in the environment and the potential for an environmental route of Ebola virus exposure," note the authors.
