A pedestrian wades through a flooded street in the typhoon-hit town of Shangchung in Taipei county August 25, 2004. Typhoon Aere triggered mudslides and flash floods in northern Taiwan on Wednesday, forcing thousands to flee their homes and Taipei financial markets and schools to close for a second day. The typhoon, the worst to threaten Taipei this year, is expected to hit landfall in southern China later on Wednesday. REUTERS/Richard Chung.

Malaria parasites

Malaria parasites. Coloured scanning electron micrograph (SEM) of malaria parasites (Plasmodium sp., yellow) bursting from the surface of a culture cell (purple/blue). These protozoans are transmitted to humans by infected mosquitoes when they drink blood. They travel through the bloodstream to the liver where they multiply inside liver cells, before moving back into the bloodstream to infect red blood cells. A cycle of fever, the main symptom of the disease, is caused by the rupture of infected red blood cells. Malaria is treated with antimalarial drugs such as quinine.
