[Hepatitis B and hepatitisC in 2005 in Poland. Unexpected increasing].

In 2005 the increasing of number of cases and incidence rate of hepatitis B was noted for the first time in last 12 years and in the first time in the period of intensive control of this disease. Also the high increasing of number of cases and incidence rate of hepatitis C was noted in 2005. On the basis of analysis the conclusion was withdrawn that change of the way of publication of statistical and epidemiological material introduced according to suggestions of European Commission concerning hepatitis B and C was the most important cause of this observation. Notsatisfactory changes of way of sterilisation of medical equipment in relation to difficulties of financial problems may be the serious affair of these observations. The low incidence rate of hepatitis B in big part of voivodeships may be also a cause of these observations connected with periodical increasing and decreasing of number of cases.
