Acute lung injury and other serious complications of Plasmodium vivax malaria.

Plasmodium vivax infection is classified among the so-called benign malarias, but it is increasingly recognised that serious and even life-threatening complications may occur. We present the case of a returning traveller with P vivax infection who developed acute lung injury 3 days into treatment, and discuss the serious complications of this infection. The case highlights the fact that P vivax infection is benign by name but not always by nature.
