In response to increased concerns about emerging infectious diseases, GeoSentinel, the Global Surveillance Network of the International Society of Travel Medicine in partnership with the US Centers for Disease Control and Prevention (CDC), was established in 1995 in order to serve as a global provider-based emerging infections sentinel network, conduct surveillance for travel-related infections and communicate and assist global public health responses. This review summarizes the history, past achievements and future directions of the GeoSentinel Network. ⋯ Surveillance of travel- and migration-related infectious diseases has been the main focus of GeoSentinel for the last 25 years. However, GeoSentinel is now evolving into a network that will conduct both research and surveillance. The large number of participating sites and excellent geographic coverage for identification of both common and illnesses in individuals who have traversed international borders uniquely position GeoSentinel to make important contributions of travel-related infectious diseases in the years to come.

With air travel restarting, there has been much discourse about the safety of flying during the pandemic. In travel medicine, risk assessment includes estimating baseline risk to the traveller, recognizing factors that may modify that risk, considering the role of interventions to decrease that risk and accounting for a traveller's perception and tolerance of risk. The goals of this review are to identify the in-flight transmission risks of commercial air travel, provide recommendations about the risks of flying during the pandemic and propose strategies to mitigate the spread of COVID-19. ⋯ In-flight transmission of SARS-CoV-2 is a real risk, which may be minimized by combining mitigation strategies and infection prevention measures including mandatory masking onboard, minimizing unmasked time while eating, turning on gasper airflow in-flight, frequent hand sanitizing, disinfecting high touch surfaces, promoting distancing while boarding and deplaning, limiting onboard passenger movement, implementing effective pre-flight screening measures and enhancing contact tracing capability. Assessing risk is a cornerstone of travel medicine. It is important to evaluate the multiple factors contributing to the cumulative risk of an individual traveller during the COVID-19 pandemic and to employ a multi-pronged approach to reduce that risk.

Meta Analysis
Etiology of fever in returning travelers and migrants: a systematic review and meta-analysis.
Numerous publications focus on fever in returning travellers, but there is no known systematic review considering all diseases, or all tropical diseases causing fever. Such a review is necessary in order to develop appropriate practice guidelines. ⋯ Malaria accounted for one-fifth of febrile cases, highlighting the importance of rapid malaria testing in febrile returning travellers, followed by other rapid tests for common tropical diseases. High variability between studies highlights the need to harmonize study designs and to promote multi-centre studies investigating predictors of diseases, including of lower incidence, which may help to develop evidence-based guidelines. The use of clinical decision support algorithms by health workers which incorporate clinical predictors, could help standardize studies as well as improve quality of recommendations.

The coronavirus pandemic (COVID-19) has spread worldwide via international travel. This study traced its diffusion from the global to national level and identified a few superspreaders that played a central role in the transmission of this disease in India. ⋯ COVID-19 got induced into Indian states mainly due to International travels with the very first patient travelling from Wuhan, China. Subsequently, the contacts of positive cases were located, and a significant spread was identified in states like Gujarat, Rajasthan, Maharashtra, Kerala and Karnataka. The COVID-19's spread in phase one was traced using the travelling history of the patients, and it was found that most of the transmissions were local.
