Observational Study
Incidence and predictors of severe altitude illness symptoms in Mt. Kilimanjaro hikers; a prospective cohort study.
Each year several Mt. Kilimanjaro hikers die due to altitude illness (AI) although urgent descent is technically easily possible. The objectives of this study were to determine the incidence and predictors of severe altitude illness (SAI) symptoms and of summit success in Mt. Kilimanjaro hikers, and the measures taken when AI symptoms develop. ⋯ The incidence of SAI symptoms in Mt. Kilimanjaro hikers was observed to be high. However, how hikers reacted during symptoms was not appropriate. Therefore, travel health counsellors should emphasize even more that hikers do not ascend higher until mild symptoms have resolved and that it is vital to descend immediately when severe symptoms develop. In addition, they can be informed on the measures, which improved summit success.

Annual global travel reached an all-time high of 1.4 billion international tourist visits in 2019. It is estimated that injury accounts for close to 25% of deaths in travellers, most of which are theoretically preventable. However, there are limited data available on injury occurrence and outcomes in travellers. Our objective was to better understand the relative risk of dying from injury that arises from the novel environments and behavioural changes associated with foreign travel. ⋯ Tourists should be aware of the increased risk of dying from road traffic hazards, drowning and homicide while traveling abroad. Specific geographies and activities associated with higher risk should be emphasized. Travel medicine practitioners and organizations that send people abroad should counsel travellers regarding these risks and seek ways to reduce them, including encouraging potential risk-mitigating behaviours. There is a need to improve systems of data collection and reporting on injury deaths in travellers and to study the impact of pre-travel and institutional interventions aimed at reducing this risk.

Risk factors for acute mountain sickness in travelers to Cusco, Peru: Coca leaves, obesity, and sex.
Acute mountain sickness (AMS) may occur after rapid ascents to altitudes >2500 m. Cusco (3350 m) in Peru is a popular destination for altitude inexperienced travellers. This study aimed at evaluating the incidence and risk factors for AMS among a cohort of foreign Spanish language students in Cusco. ⋯ In our cohort, AMS affected two out of five travellers. Obesity and female sex were associated with increased risk. Drinking coca leaf tea for prevention did not decrease the risk of AMS. Acetazolamide prophylaxis was associated with decreased risk of AMS.
