Key result
Echovirus type 7 was isolated from 7 conjunctival scrapings of patients with eye disease, suggesting an etiologic association despite atypical viral characteristics.
Observational (n=7)
Echovirus type 7 may be etiologically associated with eye disease, presenting with atypical viral characteristics such as slow adaptation to cell cultures and lack of hemagglutinin.
May support testing for echovirus 7 in unexplained conjunctivitis; leaves open causal confirmation beyond case reports.
Echovirus type 7 was isolated from 7 conjunctival scrapings obtained during an epidemic of meningoencephalitis caused by the same virus. The patients suffered from conjunctivitis or keratoconjunctivitis, and also had gastrointestinal symptoms, fever, headache and lymphadenopathy early in their illness. Two characteristics of the isolated strains were not in agreement with those of the standard echovirus type 7: they adapted only slowly to cell cultures, and no viral hemagglutinin for human red blood cells could be demonstrated. Our data suggest an etiologic association of echovirus 7 with eye disease.

Sandelin et al. (1977) conducted an observational in Conjunctivitis or keratoconjunctivitis (n=7). Echovirus type 7 was evaluated on Isolation of Echovirus type 7. Echovirus type 7 was isolated from 7 conjunctival scrapings of patients with eye disease, suggesting an etiologic association despite atypical viral characteristics.
