   Abstract : Tuberculosis (TB) infection and disease patterns among different populations are extremely heterogeneous. This thesis explores mainly by microbiological methods the epidemiology of TB in Estonia. Through the work high rates of drug resistance were found. READ MORE

4. 2. Development and evaluation of new therapeutic interventions for chronic hepatitis C virus infection

   Author : Fredrik Holmström; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The hepatitis C virus (HCV) is a major global health problem with around 130-150 million individuals chronically infected and it is estimated that 2 millions are newly infected each year. The HCV infection is one of the major causes of liver disease and the infection is characterized by a slow and silent progression. READ MORE

5. 3. Pharmacovigilance of preventive chemotherapy for the control of schistosomiasis and soil-transmitted helminths in Ethiopia

   Author : Tigist Dires Gebreyesus; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The World Health Organization (WHO) recommends preventive chemotherapy (PC) as a core public health intervention for the control and elimination of schistosomiasis and soil transmitted helminths (STHs) in endemic countries. Despite being amenable to available treatments and ongoing PC, schistosomiasis and STHs remain causes of significant morbidity and associated complications in endemic areas. READ MORE
