Frequently Asked Questions
How long is someone with COVID-19 contagious?
Most people are most infectious in the first five days of symptoms, and isolation guidance typically recommends staying away from others until fever has resolved and symptoms are clearly improving.
Do vaccinated people still need to worry about COVID-19?
Vaccination greatly reduces the risk of severe illness and hospitalization even though breakthrough infections can still occur, so staying up to date with boosters remains worthwhile, particularly for older adults and those with chronic conditions.
What is long COVID?
It refers to symptoms such as fatigue, brain fog, or breathlessness that persist for weeks or months after the acute infection clears, and anyone with lingering symptoms beyond a few weeks should see a physician for evaluation and supportive management.
Who is most at risk of severe COVID-19?
Older adults and people with conditions such as diabetes, heart disease, obesity, or a weakened immune system face the highest risk of severe illness and should seek medical advice early if they test positive.
Is a COVID-19 test still necessary if symptoms are mild?
Testing helps confirm the diagnosis, guides isolation decisions, and identifies people who may benefit from antiviral treatment, so it is still worthwhile especially for high-risk individuals or before contact with vulnerable people.
