Rocky Mountain spotted fever has been found in southern Canada, the USA, northern Mexico, Costa Rica, Panama, Brazil, and Argentina. It is transmitted through the bite of infected ticks. Travellers can reduce the risk of exposure to this infection by avoiding tick habitats such as fields and forests whenever possible. Daily tick checks and prompt removal of an attached tick will help to reduce the risk of infection.
