Storing Ebola-infected sewage for a week at 86° Fahrenheit or better should permit enough time for more than ninety nine.99 p.c of the virus to die, although decrease ambient temperatures may require a longer keeping duration, according to a brand new study by means of researchers at Georgia State university’s school of Public well being.

The learn about co-authored with the aid of Lisa M. Casanova, assistant professor of environmental health, and Scott R. Weaver, research assistant professor in Epidemiology and Biostatistics, used bacteriophage Φ6, a type of virus, as a stand-in to review how lengthy Ebola and similar viruses can live on in latrines and different systems for amassing and taking away sewage. Bacteriophage Φ6 has a lipid envelope, which means it has structural similarities to Ebola and several different types of virus, allowing for a secure find out about that did not require use of Ebola itself.

“The locations hardest hit with the aid of Ebola are the places that frequently have the least infrastructure for safely eliminating sewage and are the usage of issues like pit latrines,” mentioned Dr. Casanova. “They need the answers to questions like this.”

Their find out about, “Inactivation of an Enveloped Surrogate Virus in Human Sewage,” was once printed not too long ago in Environmental Science &amp know-how Letters.

to scale back the chance of an infection for sanitary workers, the world health organization recommends latrine waste contaminated with Ebola be held for per week or longer earlier than any efforts are made to move it.

Casanova and Weaver performed experiments on sewage samples taken from an urban wastewater reclamation facility, spiking the samples with Φ6 as a stand-in for Ebola. Their analysis discovered that at 86° Fahrenheit (equal to 30° Celsius) the virus was once primarily inactivated after 3-7 days. then again, samples examined at 72.6° Fahrenheit (or 22°C) took a few days longer to decay.

The study suggests longer keeping instances is also needed the place temperatures are decrease. Longer maintaining occasions can also be really helpful to get rid of “longer-surviving subpopulations of viruses.”
