Our results strongly indicate that HAART has decreased the risk of transmission of HIV despite increased practice of unsafe sex and thereby substantiate that HAART should be offered to MSM to reduce risk of transmission of the disease.

Worldwide the 3 most common pathogens for bacterial meningitis among infants and young children are Haemophilus influenzae, Streptococcus pneumoniae and Neisseria meningitidis. Denmark included in the National Childhood Vaccination Programme vaccination against H. influenzae type B (Hib) in 1993 and invasive pneumococcal disease as of October 2007. Introduction of the conjugated heptavalent pneumococcal vaccine is, as in the post-Hib vaccination era, expected to change the epidemiology of bacterial meningitis in infants and young children. In 1980 it became mandatory to report suspected cases of bacterial meningitis and the surveillance system was further enhanced for laboratory diagnosed cases of N. meningitis in 1992 and S. pneumoniae in 1996 when a reminder procedure to the physician was issued. In this article we review the epidemiology of 418 notified cases of bacterial meningitis in children <2 y of age in Denmark in the pre-pneumococcal vaccination era 1997-2006 and discuss points of awareness for the future surveillance system.

Campylobacteriosis is a disease of worldwide importance, but aspects of its transmission dynamics, particularly risk factors, are still poorly understood. We used data from a matched case-control study of 4,269 men who have sex with men (MSM) and 26,215 controls, combined with national surveillance data on Campylobacter spp., Salmonella spp., and Shigella spp., to calculate matched odds ratios (mORs) for infection among MSM and controls. MSM had higher odds of Campylobacter (mOR 14, 95% CI 10-21) and Shigella (mOR 74, 95% CI 27-203) infections, but not Salmonella (mOR 0.2, 95% CI 0-13), and were less likely than controls to have acquired Campylobacter infection abroad (χ 2 = 21; p<0.001). Our results confi rm that sexual contact is a risk factor for campylobacteriosis and also suggest explanations for unique features of Campylobacter epidemiology. These fi ndings provide a baseline for updating infection risk guidelines to the general population.

The yearly increase in PEP and PrEP are parallel to the yearly increase in number of travelers, and can thus be explained by the increased rate of traveling, and not by a rise in awareness of rabies risk or more bites per traveler.Even short term travelers should be given the option of including PrEP in their travel immunisation program, as PEP and especially RIG is not always available in rabies-endemic countries.
