Researchers at The Pennsylvania State University GeoVISTA Center, and at the University of Pittsburgh Graduate School of Public Health, have done a study which highlights critical areas in Niger where health services/facilities are lacking and may need to be improved using realistic travel time estimates to represent access times during seasonal variations.
Pandemic influenza A (H1N1) 2009 virus spread rapidly around the world in 2009. Multiple data sources from surveillance systems and specific investigations were used to characterize the transmission patterns of this virus in China during May-November 2009 and analyze the effectiveness of border entry screening and holiday-related school closures on transmission.
Researchers at the Johns Hopkins Bloomberg School of Public Health have found evidence of a role for neighborhood immunity in determining risk of dengue infection. While it is established that immunity can be an important factor in the large-scale distribution of disease, this study demonstrates that local variation at spatial scales of just a few hundred meters can significantly alter the risk of infection, even in a highly mobile and dense urban population with significant immunity.
Immunizations are a valuable tool for controlling infectious diseases among populations both in the U.S. and globally. Routine immunizations and supplemental immunization activities, such as immunization campaigns, are designed to provide immunization coverage to entire populations. Current measurements used to determine the success and rates of immunization can be flawed and inconsistent.
An emerging class of long-lasting flu vaccines could do more than just save people the trouble of an annual flu shot.
Princeton University-based researchers have found that the "universal" vaccine could for the first time allow for the effective, wide-scale prevention of flu by limiting the influenza virus's ability to spread and mutate. Universal, or cross-protective, vaccines — so named for their effectiveness against several flu strains — are being developed in various labs worldwide and some are already in clinical trials.
