Summary
A cost-effective testing strategy confirmed low severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) prevalence in rural Wisconsin. This approach provided crucial health and safety information to local businesses and schools.
Area of Science:
- Public Health
- Epidemiology
- Infectious Disease Control
Background:
- SARS-CoV-2 testing and mitigation often overlook rural, low-prevalence areas.
- Lack of tailored strategies impacts health and safety in these communities.
Purpose of the Study:
- Evaluate a cost-effective SARS-CoV-2 testing strategy for determining point prevalence in a rural setting.
- Address the specific needs of low-prevalence rural populations.
Main Methods:
- Voluntary testing of asymptomatic clinic employees.
- Community SARS-CoV-2 testing events for asymptomatic individuals.
- Weekly drive-up clinics for high-risk asymptomatic persons identified through contact tracing.
Main Results:
- Tested 61 employees, 268 community members, 36 high-risk asymptomatic individuals, and 128 symptomatic patients.
- Confirmed low prevalence with only 1 positive result among asymptomatic individuals and 5 among symptomatic patients.
Conclusions:
- Testing events validated low SARS-CoV-2 prevalence in the rural community.
- Provided valuable prevalence data to local businesses and schools.
- Strengthened partnerships for contact tracing and testing, offering essential services to asymptomatic individuals.

Rural Health Centers
Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...
