Patient Information: The Common Cold

The Common Cold

Introduction

What is the Common Cold?

The common cold is one of the most widespread illnesses. Most people will catch it many times in their lifetime. Adults usually get 2–3 colds a year, while children may get 4 or more, especially during school terms or crowded seasons.

It is caused by viruses (over 200 types, especially rhinoviruses, coronaviruses, adenoviruses, and parainfluenza viruses) that infect the nose, throat, and upper airways. Cold weather itself does not cause colds, but colds are more common in cooler or rainy seasons because people stay indoors, close together, making it easier for viruses to spread.

Discussion

How Does It Spread?

  • Through droplets when a sick person coughs or sneezes
  • By touching contaminated objects or surfaces and then touching your eyes, nose, or mouth
  • Close contact in schools, childcare centers, buses, and markets

 

Symptoms

Colds usually start 1–3 days after exposure and get better in 1–2 weeks.
Common symptoms include:

  • Runny or blocked nose
  • Sneezing
  • Sore throat
  • Cough
  • Headache
  • Feeling weak or unwell
  • Muscle aches
  • Mild fever (can be higher in children)
  • Earache or mild eye irritation
  • Loss of taste or smell (sometimes)

 

Self-Care at Home

Most colds get better on their own. You can:

  • Rest and drink plenty of clean fluids (water, teas, soups)
  • Wash hands regularly with soap and water (20 seconds) or use sanitizer
  • Use a clean cloth or tissue to cover your nose and mouth when sneezing or coughing
  • Gargle warm salt water (do not swallow) to soothe sore throat
  • Steam inhalation, warm baths, or humid air may ease congestion
  • Prop yourself up with pillows at night to breathe more easily
  • Use throat lozenges or sprays for sore throat relief
  • Over-the-counter remedies (paracetamol for fever, nasal decongestants) may help — ask your pharmacist
  • Home remedies like vitamin C, zinc, or ginger may provide comfort

⚠️ Do not use antibiotics – they do not work against viruses.
⚠️ Do not give aspirin to children – it can be dangerous.
⚠️ Avoid smoking and secondhand smoke – they make symptoms worse.

 

🩺 When to See a doctor

Go to a clinic or hospital if you or your child has:

Breathing problems – fast, noisy, or difficult breathing
Chest pain or tightness
High fever that does not go down
Severe sore throat or pain when swallowing
Cold lasting more than 2–3 weeks without improvement
Worsening symptoms instead of getting better
Ear pain or ear discharge
Blood in phlegm (mucus)
Confusion, dizziness, or fainting
If you have a chronic illness (like asthma, heart disease, or diabetes) and the cold makes it worse

 

👉 Important:
Most colds are mild and get better on their own. But if you notice any of these warning signs, seek medical care immediately.

 

Prevention

  • Wash hands often with soap and water
  • Avoid touching your eyes, nose, and mouth with unwashed hands
  • Keep homes and classrooms well ventilated
  • Avoid sharing utensils or cups
  • Stay up to date with recommended vaccinations (e.g., flu vaccine helps prevent flu, not colds)
  • Eat healthy foods, sleep well, and manage stress
  • Stay away from smoke and dusty environments
  • Teach children to cough or sneeze into a tissue or elbow

 

 

 

Conclusion

Key Message

The common cold is usually mild and goes away within 1–2 weeks. Good hygiene, rest, and fluids help recovery. Seek medical help if symptoms are severe, prolonged, or in vulnerable groups like young children, the elderly, or those with chronic illnesses.
