Pathogen natural history, epidemiological knowledge, human behavior and epidemic progression determine whether symptom screening and questionnaires are effective barriers to geographic spread of infection by travelers.

Gene flow analysis reveals that the genomes of most sub-Saharan populations are the result of recent historical admixture events.

The burden of antimicrobial resistance in Thailand is deteriorating over time, and 19,122 deaths in the country in 2010 were excess deaths caused by multidrug-resistant bacterial infection.

Lower malaria prevalence in females does not appear to be due to lower rates of infection but rather due to faster clearance of asymptomatic infections.

A health-system embedding method for genomic discovery and clinical characterization of disease highlights the importance of documenting a wider spectrum of genetic disorders in diverse populations.

A freely available computer program that takes into account specific local conditions enables users to predict the impact of adopting different diagnostic strategies on the spread of tuberculosis in their region.

Mobile genetic elements were identified and tracked as they exchanged between multidrug-resistant bacteria causing infections at a single hospital.

In large vaccine trials conducted in dengue-endemic Asia and Latin America, the CYD-TDV tetravalent dengue vaccine shows limited variation in intra-serotype efficacy in the target population for vaccination (>9 years).

Selection bias, also known as collider bias, likely explains the apparent protective effect of G6PD deficiency against cerebral falciparum malaria.

Long-term immune outcomes vary with age, for both adults and children in HIV-infected populations, e.g. long-term scaled carrying capacity is lower in HIV-infected younger individuals compared to older individuals.
