Household transmission of the pandemic H1N1 2009 virus infection (pH1N1) frequently occurred in children and adolescents within several days after development of index cases. However, antiviral therapy for index cases did not seem to prevent household transmission of pH1N1.

Exposure to pulmonary tuberculosis (PTB) culminates in heterogeneous outcomes, including variation in Mtb antigen-specific interferon-gamma (IFN-γ) T-cell responses. IFN-γ-independent cytokines, including tumor necrosis factor (TNF) and interleukin (IL-2), offer potential diagnostic improvements and insights into pathogenesis. We hypothesized that ESAT6/CFP10 TNF and IL-2 responses improve Mtb infection detection among exposed household contacts (HHCs) and are associated with index case Mtb aerosolization (i.

This is a prospective non-comparative experimental study aimed to investigate the presence of microsporidia in household pipe water of microsporidial keratitis (MK) patients and to describe the patients' characteristics and behavioral risk factors. This study was conducted at Walailak University Hospital, Thailand, from July 2022 to February 2024. Patients diagnosed with MK were surveyed using a questionnaire to assess personal behaviors and source of household water.

Increasing attention has focused on health outcomes of Campylobacter infections among children younger than 5 years in low-resource settings. Recent evidence suggests that colonization by Campylobacter species contributes to environmental enteric dysfunction, malnutrition, and growth faltering in young children. Campylobacter species are zoonotic, and factors from humans, animals, and the environment are involved in transmission.

Background: Highly pathogenic avian influenza A(H5N1) viruses have caused widespread infections in dairy cows and poultry in the United States, with sporadic human cases. We describe characteristics of human A(H5N1) cases identified from March through October 2024 in the United States.

Methods: We analyzed data from persons with laboratory-confirmed A(H5N1) virus infection using a standardized case-report form linked to laboratory results from the Centers for Disease Control and Prevention influenza A/H5 subtyping kit.

Knowing when and where infected mosquitoes bite is required for estimating accurate measures of malaria risk, assessing outdoor exposure, and designing intervention strategies. This study combines secondary analyses of a human behaviour survey and an entomological survey carried out in the same area to estimate human exposure to malaria-infected Anopheles mosquitoes throughout the night in rural villages in south-eastern Tanzania. Mosquitoes were collected hourly from 6PM to 6AM indoors and outdoors by human landing catches in 2019, and tested for Plasmodium falciparum sporozoite infections using ELISA.
