Sixty per cent of the Swedish population received the monovalent AS03-adjuvanted pandemic influenza vaccine in the autumn of 2009. We assessed the age-specific effectiveness of this pandemic vaccine against hospitalisation with laboratory-confirmed influenza A(H1N1)pdm09 during the season 2010/11, in the age group from six months to 64 years in Sweden. The(More)
BACKGROUND The significance of Chlamydia trachomatis (Ct) infection in the pharynx, and possible symptoms, are under discussion. Most studies have involved only homo/bisexual men. We report findings of pharyngeal Ct (PhCt) infections in patients with long-lasting throat discomfort and the prevalence of PhCt in genitally Ct-infected young people in a Swedish(More)
INTRODUCTION Nephropatia epidemica (NE), a relatively mild form of hemorrhagic fever with renal syndrome caused by the Puumala virus (PUUV), is endemic in northern Sweden. We aim to study the risk factors associated with NE in this region. METHODS We conducted a matched case-control study between June 2011 and July 2012. We compared confirmed NE cases(More)
A sudden reduction in the number of reported genital chlamydia cases was observed in Norrbotten County, Sweden, during October to November 2009. After exploring other possibilities, such as a reduction in the number of chlamydia tests analysed or a new Chlamydia trachomatis variant that had been undetected in standard laboratory tests, it was found likely(More)
Objective: To achieve optimal effect with beta-lactam antibiotics, regimens with frequent dosages have been found necessary. However, if compliance is negatively influenced by more frequent dosages, this might hamper the effect of the treatments. Therefore, we have studied whether the numbers of daily dosages influence the compliance with prescribed(More)
Isolates of Listeria monocytogenes saved from outbreaks of listeriosis, cases of sporadic listeriosis, and similar events do not always belong to a solitary genetic variant. Variants of the same strain may have evolved from a unique clone, and plasmid loss or gain and phage-mediated genetic changes are suggested as the main mechanism. Some of these reports(More)
