Hypothesis
What is the prevalence of hantavirus infection in the Ribeirao Preto region of Sao Paulo State, Brazil?
Conclusion
The seroprevalence of human hantavirus infection in the Ribeirao Preto region is estimated to be 1.23%.
Supporting Evidence
- The seroprevalence was determined to be 1.23% overall, with variations across different cities.
- 1.23% is more than twice the prevalence observed in U.S. populations at risk for hantavirus infection.
Takeaway
Researchers checked blood samples from people in Ribeirao Preto to see how many had been infected with hantavirus, and they found that about 1 in 100 people had the virus.
Methodology
A serologic survey using SNV ELISA was conducted on hospital patients requiring venipuncture for routine procedures.
Limitations
Laboratory confirmation was not available locally, and only presumptive diagnoses could be made until the SNV ELISA was developed.
Participant Demographics
Patients were slightly older but similar in sex distribution compared to the general population.
