Thus, one should not draw the wrong conclusion that immunization against influenza is useless. The account derived from GeoSentinel,3 in contrast, during a prepandemic period exceeding 10 years, 1997 to 2007, detected only 70 probable or confirmed cases of influenza A and B among the

over 37,500 ill-returned travelers. As patients with comparatively trivial illness, such as influenza, may rather consult with their family physician than a GeoSentinel site, this database may be more appropriate to evaluate serious infections, Doxorubicin manufacturer particularly rare ones. R. S. in the past 4 years has received honoraria from the pharmaceutical industry for lectures on influenza epidemiology, prevention, and therapy. Also, he was paid for participation in influenza vaccine advisory boards and for participation in influenza vaccine trials.

Wearing respiratory masks is an efficient protection against RG7204 concentration air transmitted pathogens such as influenza virus. The new pandemic with the virus influenza A (H1N1) 2009 was first detected in Southern California and Mexico during late April 2009 and then extended to the world within a few weeks. In this issue, the reader will find an editorial (pp. 1–3) and 4 articles that refer to influenza: a) carriage of infuenza virus by sick travelers across world hemispheres (pp. 4–8); b) outbreak of influenza A(H1N1) 2009 among medical students visiting the Dominican Republic (pp. 9–14); c) portage of respiratory tract pathogens in pilgrims attending the Hajj, Saudi Arabia (pp. 15–21); and d) etiologies of respiratory PJ34 HCl tract infections in returning travelers at the

onset of the pandemic of influenza A(H1N1) 2009 (pp. 22–27). Setting: Tokyo subway, 2008. Credit: Eric Caumes “
“The aim of the study was to compare the yields of newly diagnosed cases of HIV infection and advanced immunodeficiency between individuals attending a mobile HIV counselling and testing (HCT) service as participants in a population-based HIV seroprevalence survey and those accessing the same service as volunteers for routine testing. The study was conducted in a peri-urban township within the Cape Metropolitan Region, South Africa. Survey participants (recruited testers) were randomly selected, visited at home and invited to attend the mobile HCT service. They received 70 South African Rand food vouchers for participating in the survey, but could choose to test anonymously. The yield of HIV diagnoses was compared with that detected in members of the community who voluntarily attended the same HIV testing facility prior to the survey and did not receive incentives (voluntary testers). A total of 1813 individuals were included in the analysis (936 recruited and 877 voluntary testers). The prevalence of newly diagnosed HIV infection was 10.9% [95% confidence interval (CI) 9.0–13.1%] among recruited testers and 5.0% (3.7–6.7%) among voluntary testers.
