That is direct contact. Their fluid, under any circumstances, on a surface or not, be it their skin shaking hands, a Door handle after with viral load from their sweat, or them coughing up or sneezing out blood droplets . These are all "direct contact with bodily fluids"
Please note, that last example is not the same as sneezing spreading the flu. The flu will remain "airborne" for a period while the droplets of blood don't remain airborne, sure sneeze droplets can get some impressive travel but it's not the same issue, the virus is in the fluid. Medical rules for the appropriate protective gear boil down to "cover all skin" and either "filter breathing intake" or "closed circuit air if possible" ... None of these require a full airtight, spacesuit style seal around the body which is what is needed to protect from a truly airborne disease.
The flu gets a lot of its infectious capability from infecting our respiratory tract. Ebola... Not so much, sure it's damn infectious, but picture a "zone of infectious reach" the flu might get to you at 50 feet, Ebola will get you at 10 only in the worst cases, it's usually more like 5 or less.
