[Diagnosis of cerebro-meningeal infections after travel abroad].

Cerebromeningitis after travel abroad is often acute and febrile and is a serious event. The most frequent and severe cause is pernicious malaria due to Plasmodium falciparum; diagnosis is rapid by thick blood film and thin blood smear; it requires specific emergency treatment. Many other aetologies exist but they are rare; they must nonetheless be considered, keeping in mind that cosmopolitan infections can be favoured by travel conditions.
