In 2016, the Transplantation Society of Australia and New Zealand, with the support of the Australian Government Organ and Tissue authority, commissioned a literature review on the topic of infectious disease transmission from deceased donors to recipients of solid organ transplants. The purpose of this review was to synthesize evidence on transmission risks, diagnostic test characteristics, and recipient management to inform best-practice clinical guidelines. The final review, presented as a special supplement in Transplantation Direct, collates case reports of transmission events and other peer-reviewed literature, and summarizes current (as of June 2017) international guidelines on donor screening and recipient management.

  • The National Institute of Epidemiology (NIE) in India evaluated its Field Epidemiology Training Programme (FETP) after admitting 80 trainees from 2001-2007 to identify strengths and weaknesses.
  • The evaluation involved analyzing data through a logic model that included inputs, processes, outputs, and outcomes, supported by reviews of documents and an anonymous online survey of graduates.
  • Results showed that 86% of graduates gained essential competencies, but challenges remained regarding faculty-to-student ratios and specific skill areas like laboratory sciences and data analysis, indicating a need for program enhancement and better career pathways for field epidemiologists in India.

We investigated chikungunya outbreaks in South India and observed a high attack rate, particularly among adults and women. Transmission was facilitated by Aedes aegypti mosquitoes in peridomestic water containers, as indicated by a high Breteau index. We recommended vector control measures and health education to promote safe water storage practices.
