BACKGROUND The number of diagnosed cases of Chlamydia trachomatis infection has been increasing in the past years in Norway although the testing rate has been relatively stable. The aim of this study was to measure the prevalence of genital Chlamydia trachomatis in young men and women in one county in Norway and determine associated factors in order to(More)
BACKGROUND Norway is classified as a low prevalence country for hepatitis B virus infection. Vaccination is only recommended for risk groups (intravenous drug users (IDUs), Men who have Sex with Men (MSM), immigrants and contacts of known carriers). We describe the epidemiology of reported cases of hepatitis B in Norway, during the years 1992-2009 in order(More)
INTRODUCTION The number of Chlamydia trachomatis infections in Norway has been increasing for the last years. A new and enhanced surveillance system was implemented in 2005 to meet the challenges faced by the increasing number of cases. METHODS The new surveillance system is laboratory based. Data are collected once a year from all laboratories on the(More)
BACKGROUND As most genital Chlamydia trachomatis infections are asymptomatic, many patients do not seek health care for testing. Infections remain undiagnosed and untreated. We studied whether screening with information and home sampling resulted in more young people getting tested, diagnosed and treated for chlamydia in the three months following the(More)
BACKGROUND Surveillance of Neisseria gonorrhoeae antimicrobial susceptibility in Europe is performed through the European Gonococcal Antimicrobial Surveillance Programme (Euro-GASP), which additionally provides data to inform the European gonorrhoea treatment guideline; currently recommending ceftriaxone 500 mg plus azithromycin 2 g as first-line therapy.(More)
BACKGROUND Lack of Hepatitis C virus (HCV) incidence data in (Norwegian) high-risk groups impedes the ability to make informed decisions on prevention measures. Thus we rely on modelling to estimate the incidence and burden of HCV infections. METHODS We constructed a compartmental model for HCV infections in Norway among active and former people who(More)
Travel may be associated with a higher risk of gonorrhoea and infection by antibiotic-resistant strains. The objective of this study was to estimate the risk for gonorrhoea among travellers from four Nordic European countries using surveillance data and to identify at-risk travellers to help target interventions. We retrieved gonorrhoea surveillance data(More)
BACKGROUND Transmission of group B Steptococci from mother to child during delivery may cause serious disease in some children, but this can be prevented by use of antibiotic treatment during delivery. We have estimated how antibiotic treatment of all pregnant carriers of group B streptococcus during delivery would affect the total antibiotic use in Norway.(More)
