Smallpox Transmission occurs through inhalation of airborne variola virus, usually droplets expressed from the oral, nasal, or pharyngeal mucosa of an infected person. It is transmitted from one person to another primarily through prolonged face-to-face contact with an infected person, usually within a distance of 6 feet (1.8 m), but can also be spread through direct contact with infected bodily fluids or contaminated objects (fomites) such as bedding or clothing.

Nor tetanus, which doesn't replicate in mammals so isn't fecal-oral transmission.
Mumps, influenza, measles, rubella, meningitis (viral or bacterial), pneumonococcal, varicella (chicken pox) - none of these are spread fecal-orally.
And can cause serious issues if vaccine penetration in populations are not complete. There have been several mumps outbreaks in North America and Europe in the past 5 years.
