Insights
A cholera outbreak in Peru during the summer of 1991-1992 affected 281 patients. The study indicates Peru is now an endemic zone for this new disease, with unchanged epidemiologic settings.
Area of Science:
- Epidemiology
- Infectious Diseases
- Public Health
Context:
- A significant cholera outbreak occurred in Peru during the summer of 1991-1992.
- The outbreak involved 281 patients, primarily from marginal-urban populations.
- This outbreak was noted as being earlier and larger than the preceding summer's event.
Purpose:
- To report on a new cholera outbreak in Peru.
- To analyze patient demographics and outcomes during the outbreak.
- To assess the evolving epidemiological status of cholera in Peru.
Summary:
- 281 patients were treated in a dedicated Cholera Unit, with 63% males and 36% females.
- Inpatient lethality was 0.46%, and overall mortality was 0.25%.
- The outbreak's early onset and increased scale compared to 1991 suggest a shift in disease dynamics.
Impact:
- The findings suggest Peru has become an endemic zone for cholera.
- The study highlights the need for ongoing surveillance and unchanged epidemiologic control measures.
- This research contributes to understanding cholera's endemic potential in newly affected regions.
Abstract:
We report a new outbreak of cholera on the beginning of last Summer (Dec. 91 and Jan 92). Were 281 patients, 63% male and 36% female, treated in our Cholera Unit of treatment; all of them coming from marginal-urban populations. There was a rate of lethality of inpatients of 0.46% and a mortality of 0.25% over the total of patients that we saw in our hospital; on this summer the outbreak is early and greatest than the summer of 1991. We can conclude that because of epidemic behavior during the whole 1991 and in the time elapsed of 1992, Peru has become an endemic zone of this new disease, while the current epidemiologic settings stay unchanged.
