[Assessments of retro-prospective epidemiologic research results regarding morbidity with viral hepatitis A in North-Eastern Moldavia, Romania, between 1970-2006].

Unlabelled: Viral hepatitis A (VHA) maintains the first place among hepatitis with various etiologies, by high levels of morbidity, affecting mainly children and teenagers age groups and, sometimes, with major risks in adults and when over- and co-infected with other hepatitis viruses. It also is involved in travellers' and nosocomial diseases.

Material And Method: The assessment of VHA morbidity data highlighted that VHA registered yearly values between 106.8 and 307.1% hundred thousand inhabitants, both at the national and Suceava County levels, during the period 1970-1995.

Results: An important decline (24.8-47.8% hundred thousand) was registered, between 1996 and 2006. In the Suceava County, after the epidemic peaks from '80-'90 decade, with morbidity of 379.1% hundred thousand in 1989 and 331.8% hundred thousand in 1990, inter-epidemic and epidemic periods with reduced amplitude were registered. In 2006, morbidity reached a low value of 15.0% hundred thousand.

Conclusion: Our study of "comparative epidemiology", on reported cases and those confirmed by hospitalisation, in the Suceava County, highlighted that the later proportion was under 50%, with an increase during 2005 (> 90%). A significant decrease in multi-annual trend of VHA morbidity registered for reported cases but not for those hospitalised.
