An MMWR analysis of six outbreaks of adenovirus-associated epidemic keratoconjunctivitis from 2008 through 2010 provides lessons on infection control in healthcare settings. Epidemic keratoconjunctivitis is a severe form of viral conjunctivitis with symptoms that can last up to 21 days and may be associated with common ophthalmologic procedures.

The healthcare-associated outbreaks occurred in Florida, Illinois, Minnesota, and New Jersey. Healthcare providers were likely sources of transmission in four of the outbreaks, and infection control breaches occurred in all. Over 400 patients were infected.

MMWR‘s editors recommend the following infection-control measures:

• Use strict hand hygiene.
• Wear disposable gloves for potential contact with eye secretions.
• Disinfect ophthalmologic instruments after every use, or use disposable instruments.
• Ensure patients with suspected conjunctivitis have a separate waiting room, sign-in area, and exam room.
• Bar from work any staff members with signs of epidemic keratoconjunctivitis.

In addition, the editors note, isopropyl alcohol is not sufficient for disinfecting ophthalmologic instruments that contact typically sterile body sites; rather, staff should follow equipment manufacturer’s instructions.
