What can I do with this?
Weekly readings give context. Your symptoms and a healthcare provider’s advice matter more for personal decisions.
General information for respiratory illnesses, not a diagnosis or personal medical advice. Trouble breathing or chest pain needs emergency medical care. Follow illness-specific guidance for measles and other infections.

Best For
Quick local infectious-disease orientation before deeper chart review
Use the top half of this page for the latest statewide signals relevant to Troy, not exact city case counts. Public dashboards do not identify every ordinary cold or local cluster. The lower community-context section is older CDC PLACES data about respiratory burden and access to care, included to explain possible impact rather than current spread.

Secondary context
Community context that can change impact
This does not tell you what is spreading this week. These older community estimates help explain respiratory vulnerability and access to care in Troy. They do not describe what is spreading this week. The measures below use CDC PLACES city estimates from 2022.
Respiratory burden
9.4%
Asthma
Higher asthma prevalence can mean more people feel respiratory surges harder.
Chronic lung disease
4.2%
COPD
COPD can raise the stakes when respiratory infections rise, especially for older adults.
Access to care
4.5%
Uninsured
Higher uninsured rates can make prevention, testing, and treatment harder to reach quickly.
Preventive care reach
79.4%
Annual Checkup
Routine checkups make vaccination, follow-up, and early care easier when illness is spreading.

Frequently Asked Questions
What illnesses are going around in Troy, Michigan right now?
The available readings are low. That does not mean nobody is sick. These are Michigan statewide readings. Public dashboards do not identify every ordinary cold or local cluster. Measles is shown separately as 15 cases in the current state tracker view in the approximate Michigan tracker through Sep 24, 2026; that is not a Troy case count or formal outbreak status.
Is the flu bad in Troy right now?
Flu activity in Michigan (which includes Troy) is currently low with 1.2% ILI. The dated CDC Rt direction estimate suggests activity may be increasing. See the Michigan flu page for weekly trend charts.
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 Troy, such as asthma burden or uninsured adults, so the infection data has clearer local context.
Does Troy have its own health data, or is this state-level?
This page combines two types of public-health data. Flu, COVID-19, RSV, and measles use Michigan statewide surveillance as context relevant to Troy; they are not exact Troy case counts. The lower community-context section adds slower Troy-specific CDC PLACES estimates about respiratory vulnerability and access to care. Public dashboards can miss ordinary colds and small local clusters, so use local health-department notices for confirmed local events.
