Rift Valley fever in South Africa- update

On 11 May 2010 Bernhard-Nocht-Institute for Tropical Medicine in Germany reported that additional laboratory analyses conducted both in Germany and South Africa on the German tourist who was preliminarily diagnosed with Rift Valley Fever (RVF) following her return from South Africa, was in-fact infected with Rickettsia and not with RVF virus.

Rickettsia, commonly known as tick fever is a bacterium which can cause many diseases that are transmitted by blood-sucking parasitic arthropods such as fleas, lice and ticks. Symptoms of rickettsial infections include rash, fever, and flulike symptoms. African tick bite fever is caused by rickettsia africae and tends to be a milder illness, with less prominent rash and little tendency to progress to complicated disease. All rickettsial diseases respond to treatment with antibiotics such as doxycycline and tetracycline.
