Observational Study
Post-treatment haemolysis is common following oral artemisinin combination therapy of uncomplicated malaria in travellers.
Artemisinin-based combination therapy (ACT) for the treatment of malaria is highly effective, well tolerated and safe. Episodes of delayed haemolysis occur in up to 57.9% of patients with severe malaria treated with intravenous artesunate, mainly caused by 'pitting' of infected red blood cells in the spleen and the delayed loss of these once-infected RBCs (oiRBCs). Several reports indicate that post-treatment haemolysis (PTH) also occurs in uncomplicated malaria treated with oral ACT, calling for systematic investigation. ⋯ PTH is common in patients with uncomplicated malaria and oral ACT. While the observed loss of haemoglobin will often not be clinically relevant, it could aggravate pre-existing anaemia, warranting follow-up examinations in populations at risk.

Melioidosis, caused by Burkholderia pseudomallei, may be considered a neglected tropical disease that remains underdiagnosed in many geographical areas. Travellers can act as the sentinels of disease activity, and data from imported cases may help complete the global map of melioidosis. ⋯ As post-pandemic travel soars, health professionals should be aware of the possibility of imported melioidosis with its diverse presentations. Currently, no licensed vaccine is available, so prevention in travellers should focus on protective measures (avoiding contact with soil/stagnant water in endemic areas). Biological samples from suspected cases require processing in biosafety level 3 facilities.

International travellers may seek care abroad to address health problems that arise during their trip or plan healthcare outside their country of residence as medical tourists. ⋯ International travellers encounter health problems during travel that often could be prevented by pre-travel consultation. Travellers obtaining planned healthcare abroad can experience negative health consequences associated with treatments abroad, for which pre-travel consultations could provide advice and potentially help to prevent complications.
