How can I tell if it's flu, COVID or RSV?

Usually you can't from symptoms alone. All three can cause fever, cough, sore throat, a runny nose, tiredness and aches. Flu often starts suddenly, RSV in healthy adults often feels like a cold, and COVID varies widely from person to person. A home COVID test can help, and a doctor can assess you and test as clinically appropriate when the result would change your care — for example, if you are in a higher-risk group.

When is shortness of breath an emergency?

Call 911 or go to the ER straight away if you are struggling to breathe, cannot finish a sentence, have chest pain or pressure, or your lips or face look bluish or grey. In a child or baby, fast or laboured breathing, the skin between or under the ribs pulling in with each breath, or pauses in breathing are emergencies. Breathlessness that is mild but getting steadily worse still needs a same-day medical assessment.

Is RSV dangerous for babies?

It can be. In older children and adults RSV is usually a cold, but in babies — especially those under 6 months, and those born early or with heart or lung conditions — it can inflame the small airways and make breathing hard. Watch for fast or laboured breathing, ribs pulling in, pauses in breathing, poor feeding and fewer wet nappies. Any of these means the baby needs to be seen urgently.

Do I need antibiotics for the flu?

No. Flu, RSV and COVID are caused by viruses, and antibiotics do not work against viruses. Taking them when they are not needed can cause side effects and contributes to antibiotic resistance. A doctor may prescribe antibiotics if a bacterial complication develops, such as some ear infections or pneumonia. For flu, antiviral medicines exist and work best when started early, so people at higher risk should be seen promptly.

When should I see a doctor for the flu?

See a doctor early — ideally within the first 48 hours — if you are in a higher-risk group, such as being 65 or older, pregnant, or living with a heart or lung condition, diabetes or a weakened immune system. Anyone should be seen if a fever lasts more than about three days, if symptoms improve and then return worse, or if ear pain, sinus pain or a worsening cough develops. Breathing difficulty, chest pain or confusion means the ER.

Flu, RSV or COVID? When to See a Doctor This Autumn in Amman

Schools are back, the weather is turning, and with it comes respiratory virus season in the Northern Hemisphere. Over the coming weeks flu, respiratory syncytial virus (RSV) and COVID will move through homes, classrooms and offices — often at the same time. Most people will recover within a few days to a week or two, but some become seriously ill, and knowing the warning signs early is what makes the difference.

How the three compare

All three share a long list of symptoms: fever, cough, sore throat, runny nose, tiredness and body aches. There are general patterns, but they are not hard rules:

Flu: usually starts suddenly — fever, chills, muscle aches and exhaustion within hours. Many people describe it as hitting them all at once.
RSV: in most healthy adults it feels like a cold. It is most dangerous for babies and older adults, where it can affect the small airways and lungs.
COVID: highly variable, from a mild cold-like illness to serious disease. Loss of taste or smell can still happen, but it is less commonly reported than early in the pandemic.

Because the overlap is so large, you can't be sure which virus it is without a test. A home COVID test can help, and a doctor can assess you and test as clinically appropriate when the result would change your care. But for most people the more useful question isn't "which virus is this?" — it's "do my symptoms need a doctor?"

Who is at higher risk

Babies and young children, especially those under 6 months.
Adults aged 65 and over.
People who are pregnant.
People with long-term heart or lung disease, including asthma.
People with diabetes.
People with a weakened immune system from illness or treatment.

Home care that helps

Rest: your body needs its energy to fight the infection.
Fluids: drink regularly so your urine stays pale — fever increases fluid loss.
Paracetamol: for fever and aches, at the dose on the label for age and weight.
No aspirin for children: don't give aspirin to anyone under 16 unless a doctor has prescribed it.
Antibiotics don't treat viruses: they won't speed up recovery from flu, COVID or RSV.

When to go to urgent care

Not every case needs the ER, but some symptoms deserve a same-day assessment at urgent care:

Symptoms improved, then came back or got worse again.
A fever lasting more than about three days in an adult.
Ear pain or sinus pain.
A cough that is getting worse instead of better.
Any symptoms in someone from a higher-risk group.

That last point matters: antiviral medicine for flu works best when started early, typically within 48 hours of symptoms starting. So older adults, pregnant people and those with chronic conditions shouldn't wait until they feel worse before being seen.

When it's the ER

Call 911 or go to the emergency department straight away for any of the following.

In adults

Difficulty breathing or shortness of breath.
Persistent pain or pressure in the chest or abdomen.
Bluish lips or face.
Confusion, persistent dizziness, or being hard to wake.

Fast or laboured breathing, or ribs pulling in with each breath.
Pauses in breathing.
Bluish lips or face.
Poor feeding or refusing drinks, fewer wet nappies, or no tears when crying.
A child who isn't alert or interacting, or is hard to wake.
Seizures.
Any fever in a baby under 3 months.

Prevention this season

Seasonal flu vaccine: recommended every year for most people from 6 months of age, and the WHO stresses it especially for higher-risk groups. Ask your doctor or pharmacist which vaccines are right for you.
Handwashing: regularly with soap and water, especially before eating and after coughing or sneezing.
Staying home when sick: keep unwell children home from school until they recover, and cover coughs and sneezes.
