Prevalence of immunity to hepatitis A in recruits to the British Army and Royal Air Force.
Between 1989 and 1992, 92% of a sample of 2790 Service recruits aged between 17 and 35 years (mean age 19 years 7 months) were found not to be immune to infection by hepatitis A virus. The proportion of males with immunity was consistently greater than that for females. There was a significantly increased probability of immunity if individuals originated from Northern England, the Midlands and Scotland, in particular the suburbs. Among male recruits there were significantly increased probabilities of immunity associated with travel to Southern and Eastern Europe or to the Tropics, and for females with travel to North West Europe or to Southern and Eastern Europe.
