Lee CS, et al. - In this retrospective analyses, researchers sought to ascertain host and pathogen factors predictive of outcomes in patients having keratoconjunctivitis. Participants from United States, India, Brazil, and Sri Lanka were included in this trial. As per the results, no association was seen between the substantial proportion of keratoconjunctivitis and a detectable adenovirus. Those with adenovirus D keratoconjunctivitis had a more severe clinical course than those with non–adenovirus D species infections or adenovirus-negative keratoconjunctivitis. An association of high viral load at presentation and non-United States origin of participants and the poorer clinical outcome was seen.
