Among children in low-resource settings, diverse enteropathogens share common, population-level antibody dynamics, which creates a new opportunity to estimate transmission through serologic surveillance.
Antibody responses to individual and optimal combinations of P. vivax recombinant proteins in naturally-exposed populations help to identify correlates of protective immunity, and establish a clear path to testing a multicomponent P. vivax vaccine.
Human mobility drives malaria importation within countries and threatens elimination interventions, but can be measured using new approaches that combine parasite genetics, mobile phone data, travel surveys and models.
New mammarenaviruses have been identified from rodents in Cambodia and Thailand, and the Cardamones variant of Wēnzhōu virus has been found in Cambodian patients presenting with fever and respiratory symptoms.
An individual-based model estimates exogenous boosting of immunity following re-exposure to chickenpox is limited to 2 years after re-exposure, but an increase in herpes zoster incidence is still expected to occur following universal varicella vaccination.
