Because of the extreme isolation of this and other communities affected by bat-transmitted rabies, preventive measures should be directed at decreasing the risk of nocturnal exposure to bats by bat proofing dwellings or use of mosquito nets and at prompt wound care. Rabies pre-exposure or postexposure vaccination is clearly indicated, but may not be feasible in these isolated populations.

Se pretende determinar el nivel de contaminación del agua potable con arsénico, así como la frecuencia de presentación de los cánceres en la ciudad de Tacna, durante los años 2007-2010. Material y Métodos: El nivel de contaminación del agua potable se determinó mediante la toma de muestra de piletas domiciliarias de los distritos de la ciudad. La frecuencia del cáncer se determinó mediante la revisión de los registros de anatomía patológica de EsSalud de los años 2010-2011. Resultados: El nivel de arsénico medio en el agua potable de la ciudad de Tacna es de 0,056 mg/L. Los niveles más altos de arsénico en las piletas de agua potable fueron detectados en los distritos de Pocollay, Ciudad Nueva y Tacna Cercado. Las neoplasias malignas más frecuentes en EsSalud Tacna durante los años 2010-2011 han sido cáncer de piel...

Severe life-threatening cholera associated with blood group O in Peru: implications for the Latin American epidemic

Of 463 persons in 69 households, 173 (37%) reported diarrhea, 21% required rehydration therapy, and 4% were hospitalized; these treatment requirements greatly exceeded estimates based on other populations. Elevated vibriocidal or antitoxic antibody titers were present in 52% of 321 from whom serum was obtained; 73% were blood group O. Blood group O was strongly associated with severe cholera: Infected persons had more diarrheal stools per day than persons of other blood groups, were more likely to report vomiting and muscle cramps, and were almost eight times more likely to require hospital treatment. Since prevalence of blood group O in Latin America may be the world's highest, estimates of treatment requirements should be increased to prevent unnecessary deaths.
Outbreak of human rabies in the Peruvian jungle

These aspects of the disease were investigated during an outbreak in Peru in early 1990. Between Jan 1 and April 30, 1990, 29 (5%) of 636 residents of the two rural communities in the Amazon Jungle in Peru acquired an illness characterised by hydrophobia, fever, and headache and died shortly thereafter. A census in one of the two towns revealed that the proportion affected was significantly higher for 5-14 year olds (17%) than for other age-groups (p less than 10(-5). Interviews conducted with 23 of the patients or their families revealed that 22 (96%) had a history of bat bite, compared with 66 (22%) of 301 community members who remained healthy (p less than 10(-6). A rabies virus strain identical to those isolated from vampire bats (Desmodus rotundus) was isolated from the brain of the only person on whom necropsy could be don...
