Abstract
The West Africa Ebola virus (EBOV) outbreak has highlighted the need for effective disinfectants capable of reducing viral load in a range of sample types, equipment and settings. Although chlorine-based products are widely used, they can also be damaging to equipment or apparatus that needs continuous use such as aircraft use for transportation of infected people. Two aircraft cleaning solutions were assessed alongside two common laboratory disinfectants in a contact kill assay with EBOV on two aircraft relevant materials representative of a porous and non-porous surface. A decimal log reduction of viral titre of 4 is required for a disinfectant to be deemed effective and two of the disinfectants fulfilled this criteria under the conditions tested. One product, Ardrox 6092, was found to perform similarly to sodium hypochlorite, but as it does not have the corrosive properties of sodium hypochlorite, it could be an alternative disinfectant solution to be used for decontamination of EBOV on sensitive apparatus.

Summary
The worst outbreak of Ebola virus disease (EVD) started in Guinea, West Africa [1] in December. 2013, and over two years later sporadic cases were still occurring. The outbreak spread to multiple countries with Guinea, Sierra Leone and Liberia being affected. 28,600 cases and more than 11,300 deaths have been reported by the World Health Organization (WHO) [2]. In addition to cases in West Africa, infected personnel have been evacuated out of Africa, and facilities in Europe and the United States have treated Ebola virus (EBOV)-infected patients. West Africa to work in laboratories, hospitals, treatment centres, holding centres or in the local communities to provide diagnostics, treatment and care and advice to try and halt the spread of the disease. Often working in temporary or adapted buildings with re-purposed equipment, personnel were reliant on personal protective equipment and disinfection for effective infection control
