Secondary context

11.8%
Asthma
Higher asthma prevalence can mean more people feel respiratory surges harder.
Chronic lung disease
7.3%

Access to care
18.9%
Uninsured
Higher uninsured rates can make prevention, testing, and treatment harder to reach quickly.
Preventive care reach
78.0%

Is the flu bad in Waterbury right now?

Why does this page include city-level community context?
The lower community-context section does not show what is spreading this week. It uses CDC PLACES (2022 data) to show slower-moving local vulnerability and access-to-care patterns in Waterbury, such as asthma burden or uninsured adults, so the infection data has clearer local context.
Does Waterbury have its own health data, or is this state-level?
This page combines two types of public-health data. The infectious disease section (flu, COVID, RSV, measles) shows Connecticut state-level surveillance, which is the most reliable available indicator for the Waterbury area right now. The lower community-context section adds slower Waterbury-specific CDC PLACES estimates about respiratory vulnerability and access to care. State infectious disease data reflects overall trends that apply to communities within the state, including Waterbury.
