Testing is the way to identify the virus. If you are at higher risk of severe illness, contact a healthcare provider promptly rather than waiting to identify it on your own: treatment for flu and COVID-19 can be time-sensitive.
How flu, a cold, and COVID-19 symptoms compare
Each illness is caused by a different virus, but the symptoms overlap. A runny nose or sore throat can occur with a cold, flu, or COVID-19; a symptom pattern can suggest possibilities but cannot confirm a diagnosis.
| Illness | Symptoms that may occur | What symptoms can—and cannot—tell you |
|---|---|---|
| Common cold | Runny nose, cough, and sore throat are common. | Cold symptoms usually improve with time. Many different viruses cause cold-like symptoms, including viruses that cause flu and COVID-19, so a cold-like illness does not establish that it is a cold. CDC common-cold guidance. |
| Flu | Fever or chills, cough, fatigue, sore throat, congestion, body aches, headache, and sometimes vomiting or diarrhea. | Not everyone with flu has a fever. These symptoms overlap with COVID-19 and cannot distinguish the two by themselves. CDC comparison of flu and COVID-19. |
| COVID-19 | Fever or chills, cough, shortness of breath, fatigue, sore throat, congestion, aches, headache, vomiting, diarrhea, and changes in taste or smell. | Taste or smell changes are more frequent with COVID-19, but are not a dependable standalone test. COVID-19 also overlaps with flu and other respiratory viruses. CDC comparison of flu and COVID-19. |
Why common rules of thumb can mislead
Sudden symptoms do not prove flu, no fever does not prove a cold, and a change in taste or smell does not prove COVID-19. CDC says symptoms alone cannot distinguish flu from COVID-19 because many signs and symptoms are the same.
Should you test for flu or COVID-19?
Testing can identify the infection and help guide treatment. Some NAAT/PCR tests can detect flu and COVID-19 at the same time, and combination tests can identify a coinfection. A positive result for one virus does not mean another virus is absent; coinfection can occur, though it is uncommon. CDC flu and COVID-19 information.

Understand a negative result
A negative antigen test does not always rule out infection, particularly when respiratory viruses are circulating widely. CDC recommends molecular tests such as NAATs for symptomatic people when flu or COVID-19 is suspected and timely treatment may be indicated. Follow the test instructions and ask a clinician about what to do next if symptoms continue or worsen. CDC respiratory virus testing guidance.

When treatment timing matters
People at higher risk of severe illness from flu or COVID-19 should contact a healthcare provider right away when respiratory symptoms begin, even if symptoms are mild. Do not wait for symptoms to reveal which virus you have or delay a call while arranging a test; a clinician can advise whether testing or early treatment is appropriate. CDC guidance for people who are sick.
Flu and COVID-19 treatment windows
Flu antivirals are prescription medicines and work best when started within 1–2 days after symptoms begin. CDC recommends prompt antiviral treatment for people with suspected or confirmed flu who are at increased risk of serious complications. COVID-19 treatment should start within 5–7 days after symptoms begin; flu treatment is most effective when begun within 2 days. These are treatment windows, not a reason to self-prescribe: a clinician must assess the person and determine appropriate care.

What may help with a cold
There is no cure for the common cold, but it should improve on its own. Over-the-counter pain relievers and fever reducers can ease symptoms; check the product label for age limits and directions, and ask a pharmacist or clinician about interactions or whether a medicine is appropriate. These medicines relieve symptoms but do not cure the infection. Antibiotics do not treat viral colds and should be used only if a clinician identifies a bacterial infection. CDC common-cold guidance.
