Historical surveillance offers baseline for enterovirus patterns; leaves open relevance to current myocarditis or surveillance needs.
Observational (n=6,822)
Yes
The study documents the predominant enteric virus types circulating in Ontario between 1960 and 1962, highlighting significant year-to-year variation.
Kelen et al. (1963) conducted an observational in Suspected viral infections (n=6,822). Viral surveillance was evaluated on Viral isolations and identification. Viral surveillance of 6,822 specimens in Ontario from 1960-1962 yielded 681 isolations, predominantly enteroviruses (74%), with the most common types varying each year.
