Installing lidded toilets and closing the lid prior to flushing also reduces the risk of contamination.Those who have CDIs should be in rooms with other people with CDIs or by themselves when in hospital.Common hospital disinfectants are ineffective against C. difficile spores, and may promote spore formation, but various oxidants   (e.g 1% sodium hypochlorite solution) rapidly destroy spores. Hydrogen peroxide vapor (HPV) systems used to sterilize a room after treatment is completed have been shown to reduce infection rates and to reduce risk of infection to others. The incidence of CDI was reduced by 53% or 42% through use of HPV. Ultraviolet cleaning devices, and housekeeping staff especially dedicated to disinfecting the rooms of people with C. difficile after discharge may be effective. Treatment
Carrying C. difficile without symptoms is common. Treatment in those without symptoms is controversial. In general, mild cases do not require specific treatment. Oral rehydration therapy is useful in treating dehydration associated with the diarrhea. Medications
Several different antibiotics are used for C. difficile, with the available agents being more or less equally effective.Vancomycin or fidaxomicin by mouth are the typically recommended for mild, moderate, and severe infections. They are also the first-line treatment for pregnant women, especially since metronidazole may cause birth defects. Typical vancomycin 125mg is taken four times a day by mouth for 10 days. Fidaxomicin is taken at 200 mg twice daily for 10 days.
Keratoconjunctivitis is inflammation ("-itis") of the cornea and conjunctiva. When only the cornea is inflamed, it is called keratitis; when only the conjunctiva is inflamed, it is called conjunctivitis. Causes
There are several potential causes of the inflammation:

Keratoconjunctivitis sicca is used when the inflammation is due to dryness. ("Sicca" means "dryness" in medical contexts.) It occurs with 20% of rheumatoid arthritis patients. The term "vernal keratoconjunctivitis" (VKC) is used to refer to keratoconjunctivitis occurring in spring, and is usually considered to be due to allergens. "Atopic keratoconjunctivitis" is one manifestation of atopy. "Epidemic keratoconjunctivitis" is caused by an adenovirus infection. "Infectious bovine keratoconjunctivitis" (IBK) is a disease affecting cattle caused by the bacteria Moraxella bovis. "Pink eye in sheep and goat" is another infectious keratoconjunctivitis of veterinary concern, mostly caused by Chlamydophila pecorum. "Superior limbic keratoconjunctivitis" is thought to be caused by mechanical trauma. "Keratoconjunctivitis photoelectrica" (arc eye) means inflammation caused by photoelectric UV light. It is a type of ultraviolet keratitis. Such UV exposure can be caused by arc welding without wearing protective eye glass, or by high altitude exposure from sunlight reflected from snow ("snow blindness"). The inflammation will only appear after about 6 to 12 hours. It can be treated by rest, as the inflammation usually heals after 24–48 hours. Proper eye protection should be worn to prevent keratoconjunctivitis photoelectrica. References
