THE SHORT ANSWER
Use layered prevention: review immunizations with your clinician, improve indoor air, practice hygiene and consider additional precautions when exposure or personal risk is higher. No single step removes all risk.
What is useful to understand?
Plan before you are sick. Keep testing instructions available and know whom to contact if symptoms start. Older adults and people with risk factors should ask about early treatment access so they do not lose time deciding where to seek help.
What can you ask or do next?
- Review current vaccine recommendations for your circumstances.
- Choose cleaner-air settings when possible.
- Keep a well-fitting mask available for higher-risk situations.
- Make a testing and care plan.
