Ebola is in the various fluids discharged by coughing and sneezing (its in the article). The problem for the urban areas is that ebola seems to persist (as long as its in a fluid) and its so infectious (small threshold exposure). The two may conspire to create an issue that 99.99% clean isn't clean enough. Thus, discharged fluids even in small amounts may very well transmit the virus in trace amounts (again, in the linked piece). From there its purely semantic about whther or not 'water vapour' or 'aerosolized liquids' are equal to "airborne". As you allude, eath pathogen may be airborne in various ways (the air has many pollutants and impurities).
