The Secretariat of Health of Campinas confirmed last Friday (12 Dec 2014) there has been 5 deaths from Rocky Mountain spotted fever (RMSF) in Sao Paulo this year. This represents an increase in the number of RMSF deaths in previous years; 3 deaths in 2013 and 3 deaths in 2012.
RMSF is caused by a bacterium, Rickettsia rickettsii which is transmitted by Dermacentor ticks found on rodents and dogs. It is usually a mild disease but is occasionally life threatening. Risk is greatest for those undertaking outdoor activities in forest or grassland areas, such as walking and camping.
Travellers should take precautions against tick bites including the use of insect repellents on the skin and clothes and covering the skin as much as possible (long sleeves and long trousers tucked into socks.
