Objective. The aim of the paper is to define the sickness rate of infectious diseases and its tendencies in Lithuania in 1998-2007. Methods. The present study attempts to evaluate the sickness rate of infectious diseases and its tendencies in Lithuania, in 1998-2007. The long-terms dynamics of the sickness rate, the structure of taken ill according to sex and age groups and seasonal prevalence. The method used to conduct the present study included describable research. The data about infectious diseases was collected and processed by means of WinPepi computer program. In order to evaluate the tendency, Mantel test was used, meaning level 0.05 was chosen. Results. The findings revealed that in the structure of infectious diseases morbidity the most striking appeared to be rotavirus, influenza, gonorrhoea, hepatitis A and B, mumps and Lyme's disease. The bigger part in the structure of bowels infectious diseases spread by means of water and food during the period 1998-2007 was caused by rotavirus — 21633 cases (37.3%). Statistics shows that the dynamics of the sickness rate during this period was significantly growing. Comparing the rotavirus morbidity according to sex: more males were sick. It should be pointed out that by age more sick between 0-3 year old (7428 cases, which make up 80.8%). The seasonal growth of sickness rate was observed in January-May, the majority of cases were recorded in March. The influenza morbidity in 1998-2007 reached 711680 cases. The dynamics of the sickness rate during this period was significantly decreasing. Comparing the morbidity according to sex, the majority of taken ill appeared to be males and by age, people 10-14 year old prevailed. The seasonal growth of sickness rate was observed in January-April, the majority of cases - in March. The bigger part in the strukcture of sexually transmitted infectious during the period 1998-2007 was caused by gonorrhoea. Statistics shows that the dynamics of the sickness rate during the periode was significantly decreasing. Comparing the gonorrhoea morbidity according to sex and age: more cases were males (81.9%) than women (18.1%) and more people between 18–24 and 25-34 year old were sick. The seasonal growth of sickness rate was observed in August-October and December. Hepatitis A and B made up the bigger part in the strukcture of viral hepatite‘s. During the period the dynamics was significantly decreasing. Comparing the morbidity according to sex and age: more males were sick and people between 0-17 year old (hepatitis A) and 18-24 (hepatitis B). The seasonal growth of sickness rate was observed in January-April. The bigger part in the structure of immunization and vaccines operated infectious durig the period 1998-2007 was caused by mumps. The dynamics of the sickness rate during this period was significantly decreasing. The majority of taken ill appeared to be males (60.5%), and people between 4-6 and 10-14 year old. The seasonal growth of sickness rate was observed in January-May. Lyme's disease made up the bigger part in the structure of vector-bone infectious diseases morbidity in 1998-2007— 16037 cases (80.3%). The dynamics of the sickness rate fluctuated — the highest Lyme's disease morbidity was in 2003, when the level of the sickness rate was 10.68/10000 population (3688 cases). The majority of taken ill appeared to be females — 3095 cases, while 1490 were males and people between 45-54 (914 cases, which make up 19.9%) and 55-64 year old (957 cases, which make up 20.9%). The seasonal growth of sickness rate was observed in July-November, and the majority cases - in October. Conclusion. The tendency of rotavirus was increasing during the period of 1998 – 2007, whereas the tendency of influenza appeared to be decreasing. However, the results showed that the tendency of Lyme's disease fluctuated during the period. The tendencies growth and decrease are statistic reliable, p< 0.05. |
