The study of prevalence of neutralization antibody against human adenovirus in ophthalmological medical workers]

We studied the prevalence of neutralization antibodies against human adenovirus (hADV) in ophthalmological medical workers as one measure for the prevention of nosocomial infection.The prevalence of neutralization antibodies against hADV-3, -4, -7, -8, -11, -19, and -37, which can cause conjunctivitis, was measured in 288 workers at ten ophthamological facilities in Japan. We studied the prevalence in different facilities, different generations, different types of workers (doctors, nurses, and others), and their medical history of hADV conjunctivitis.Among the workers, the prevalence of neutralization antibodies against hADV-3, -4, -7, -8, -11, -19, and -37 was 70.1%, 43.8%, 18.8%, 16.3%, 16.3%, 8.7%, and 6.3%, respectively. The prevalence of neutralization antibodies against hADV-8 was two times higher in doctors than in other workers. People who have a history of hADV conjunctivitis have a high prevalence of neutralization antibodies against hADV-8, -19, and-37.The prevalence of neutralization antibodies against hADV-8, -19, and-37 was low in the ophthalmological medical workers. These seroepidemiological data indicate the high possibility of an epidemic of conjunctivitis and occurrence of nosocomial infection caused by these serotypes.
