Slide 26
Rodent Exposure
70 Confirmed HPS cases

Rodent Exposure Data from 70 confirmed HPS Cases: A review of confirmed HPS cases was conducted to characterize rodent exposure. Of 70 confirmed HPS cases, 69% had peridomestic exposure; 19% had both peridomestic and occupational exposure; 9% had peridomestic and recreational exposure; 4% had occupational exposure; and 9% had rodent exposure while entering and cleaning rodent-infested structures.

Slide 27
Prevalence of SNV IgG Antibodies in
Select U.S. Populations

Seroprevalence of SNV IgG Antibodies in Select U.S. Populations: Studies focusing on select high-risk groups showed a total prevalence of SNV antibodies of 0.6% (15/2531). Antibody prevalence was 0% (0/143) for forest workers; 0% (0/396) for health care workers; 1% (3/299) for prodromal HPS patients during initial 1993 outbreak; 1.3% (3/239) for contacts of HPS patients; 0.2% (1/522) for rural OCC; and .9% (8/932) for rodent workers.

Slide 28
Prevalence of SNV IgG Antibodies in
Select South American Populations

Prevalence of SNV IgG Antibodies in Select South American Populations: Prevalence of hantavirus antibodies in select South American populations varies from region to region. Studies demonstrated an antibody prevalence of 12.8% (44/345) in Paraguay; 40.4% (78/193) among an Indian population in Western Paraguay; <1% in Argentina; 17.1 % (38/222) among an Indian population in the Salta province, Argentina; and 2-13% in Chile.
