Public health programs — especially vaccination programs — have led to dramatic declines in the incidence of contagious diseases in the United States over the past century.1-3 However, some contagious diseases are now on the rise despite the availability of vaccines. Pertussis vaccines have been available since the 1920s, but the worst pertussis epidemic(More)
OBJECTIVE To assess the pattern of diseases in a natural disaster, which are not necessarily a direct consequence of the event but can impact on the way health assistance is to be provided. METHODS Cross-sectional, record-based study in the International Committee of the Red Cross field hospital in Aceh, Indonesia, established immediately after the(More)
BACKGROUND The human impact of the tsunami that occurred on 26 December 2004 was enormous, with Indonesia bearing a huge proportion of the losses. The aftermath brought predictions of communicable disease outbreaks and widespread fear of epidemics. However, evidence from previous disasters due to natural hazards does not support all of these predictions.(More)
BACKGROUND Many countries, such as Niger, are considering changing their vaccine vial size presentation and may want to evaluate the subsequent impact on their supply chains, the series of steps required to get vaccines from their manufacturers to patients. The measles vaccine is particularly important in Niger, a country prone to measles outbreaks. (More)
Although the substantial burdens of rotavirus and pneumococcal disease have motivated many countries to consider introducing the rotavirus vaccine (RV) and heptavalent pneumococcal conjugate vaccine (PCV-7) to their National Immunization Programs (EPIs), these new vaccines could affect the countries' vaccine supply chains (i.e., the series of steps required(More)
BACKGROUND In the current information age, the use of data has become essential for decision making in public health at the local, national, and global level. Despite a global commitment to the use and sharing of public health data, this can be challenging in reality. No systematic framework or global operational guidelines have been created for data(More)
OBJECTIVES We investigated whether introducing the rotavirus and pneumococcal vaccines, which are greatly needed in West Africa, would overwhelm existing supply chains (i.e., the series of steps required to get a vaccine from the manufacturers to the target population) in Niger. METHODS As part of the Bill and Melinda Gates Foundation-funded Vaccine(More)
BACKGROUND This year, Brazil will host about 600,000 foreign visitors during the 2014 FIFA World Cup. The concern of possible dengue transmission during this event has been raised given the high transmission rates reported in the past by this country. METHODOLOGY/PRINCIPAL FINDINGS We used dengue incidence rates reported by each host city during previous(More)
BACKGROUND Currently, the only tests capable of determining the serotype associated with dengue virus (DENV) infection require sampling during the period of acute viremia. No test can accurately detect the serotype associated with past DENV infections. The standard assay for determination of serotype-specific antibody against DENV is the plaque reduction(More)
