West Nile virus activity--United States, August 4-10, 2004
Abstract:
During August 4-10, a total of 89 cases of human West Nile virus (WNV) illness were reported from 14 states (Alabama, Arizona, California, Florida, Illinois, Kentucky, Louisiana, Minnesota, Mississippi, Missouri, New Mexico, North Dakota, South Dakota, and Wyoming).
Insights
A total of 89 human West Nile virus (WNV) cases were reported across 14 US states between August 4-10. This highlights ongoing WNV surveillance and the geographic spread of the mosquito-borne illness.
Area of Science:
- Arbovirology
- Public Health Surveillance
- Epidemiology
Background:
- West Nile virus (WNV) is a significant public health concern transmitted by mosquitoes.
- Ongoing surveillance is crucial for monitoring WNV activity and geographic distribution.
Purpose of the Study:
- To report the number and geographic distribution of human WNV cases during a specific week.
- To provide timely data on WNV transmission for public health interventions.
Main Methods:
- Data collection through national public health reporting systems.
- Weekly aggregation and analysis of reported human WNV illness cases.
Main Results:
- 89 human WNV cases reported from August 4-10.
- Cases were reported across 14 diverse US states, indicating widespread WNV activity.
Conclusions:
- The reported cases underscore the continued presence and transmission of WNV across multiple states.
- Public health agencies should maintain vigilance and implement mosquito control measures.
