Absolute Event Rate: 66% vs 49%
Enterovirus 70 can cause large outbreaks even in previously exposed populations, with only partial protection from previous infection and higher attack rates in young children and women of childbearing age.
Bern et al. (1992) conducted a cross-sectional in Acute hemorrhagic conjunctivitis (n=1,095). Female sex (aged 21-40 years) vs. Male sex (aged 21-40 years) was evaluated on Acute hemorrhagic conjunctivitis attack rate. During an enterovirus 70 outbreak, the overall attack rate was 58%, with women aged 21-40 years experiencing higher attack rates than men of the same age (66% vs. 49%).
