Are you taking extra precautions to avoid viral infections during current local outbreaks?

Wastewater monitoring in Boise has identified high levels of COVID-19, norovirus, and enterovirus D68. Local health data indicates that both COVID-19 and norovirus trends have been increasing over the last 21 days.

Why it matters

Understanding viral circulation in the community through wastewater helps identify the presence of respiratory and gastrointestinal illnesses. These findings highlight the ongoing health risks posed by circulating viruses, particularly for vulnerable age groups.

Wastewater monitoring indicates high viral levels in Boise, where COVID-19 and norovirus trends have risen consistently over the previous 21 days. Children under age 7 and older adults remain the groups at highest risk for severe symptoms.

The players

Wastewater Scan

This is a public health surveillance system that monitors wastewater for various viral pathogens.

Moderna

This company is a biotechnology firm that develops and manufactures mRNA-based COVID-19 vaccines.

Pfizer-BioNTech

This partnership produces an mRNA-based vaccine that is widely used to prevent severe COVID-19 illness.

Novavax

This organization develops protein-based vaccine technology as an alternative to existing COVID-19 vaccines.

The details

Enterovirus D68 spreads via respiratory secretions, while norovirus is transmitted through contaminated surfaces, food, or water. There are currently no approved vaccines for enterovirus D68 or norovirus, though vaccines for COVID-19 are provided by Moderna, Pfizer-BioNTech, and Novavax.

Previous 21 days: COVID-19 and norovirus levels have been trending upward.

The Big Picture

This monitoring effort follows the established pattern of using environmental tracking to predict and manage public health outbreaks in local communities, much like the 2018 Cyclospora outbreak linked to McDonald's salads demonstrated the necessity of widespread pathogen surveillance.

Residents should remain aware that children under age 7 and older adults are at a higher risk for severe symptoms from these viruses. Practicing good hygiene and staying up to date on available COVID-19 vaccinations are recommended steps to manage personal health risks.

The takeaway

Maintaining awareness of local viral trends allows individuals to take proactive steps to protect high-risk family members. Practicing frequent handwashing and staying current with vaccinations are essential strategies for mitigating the impact of seasonal respiratory and gastrointestinal illnesses.
