Un examen systématique des selles après un voyage exotique a-t-il un intérêt ?

A stool sample examination should not be systematic when returning from a stay in the tropics. It must be guided by clinical, epidemiological or biological data. However, there are some circumstances that allow for a systematic approach: controlling the risk of spreading antibiotic resistance leads to the systematic screening of highly resistant bacteria in patients who have been hospitalized abroad in the year prior to their entry hospital in France. The final phase of poliomyelitis eradication justifies screening for poliovirus in adopted or migrant children who have recently entered France and originated from the two countries where wild poliovirus is still circulating. The evolution of the PCR techniques towards the enteric parasites opens new perspectives but currently limited by the low panel of parasites highlighted.
