Here is a thorough overview of the common cold with sore throat and low fever, drawn from authoritative textbook sources:
Common Cold (Acute Viral Upper Respiratory Infection)
What Is It?
The common cold is the highest-incidence illness in humans - about 3 in 4 adults and 9 in 10 children get at least one cold per year. It is caused by viral infection of the upper respiratory tract.
Common viral causes (per Goldman-Cecil Medicine & Medical Microbiology 9e):
- Rhinovirus (most common)
- Coronavirus
- Influenza / Parainfluenza viruses
- Respiratory syncytial virus (RSV)
- Adenovirus, Metapneumovirus, Bocavirus
Symptoms
| Symptom | Timing |
|---|---|
| Sore / scratchy throat | Often the first symptom |
| Sneezing | Early |
| Nasal congestion, rhinorrhea | Develop rapidly, most bothersome |
| Low-grade fever, malaise, headache | Due to interferons and inflammatory cytokines |
| Cough | Develops later, may last weeks |
A change in color/consistency of nasal secretions (yellow/green) during the illness is normal and does NOT automatically mean bacterial infection.

- Goldman-Cecil Medicine
Timeline
- Incubation: 2-8 days
- Illness duration: typically 5-10 days (some may last longer)
Treatment - What Works
Symptom relief is the goal. No antiviral therapy exists for most cold viruses.
Pain/Fever Relief
- Ibuprofen - reduces fever, headache, ear pain, muscle/joint pain, and sneezing; may be more effective than paracetamol for fever
- Paracetamol (acetaminophen) - short-term relief of rhinorrhea and nasal congestion; less effective than ibuprofen for fever
- Aspirin - avoid in children and teenagers due to risk of Reye's syndrome
Nasal Congestion
- Topical decongestants (e.g. oxymetazoline) - effective, but stop after 3 days to avoid rebound swelling ("rhinitis medicamentosa")
- Oral decongestants - some benefit
- Saline nasal drops/sprays or irrigation - safe, helps thin and clear secretions, good for all ages
- Intranasal ipratropium bromide - reduces rhinorrhea
Sore Throat
- Warm salt-water gargle (1/4-1/2 tsp salt in 120-240 mL warm water)
- Throat lozenges / hard candy (not for children under 6 - choking risk)
- Ice chips for soothing
Cough
- Antitussives/mucolytics (limited evidence)
- Acetylcysteine - may safely reduce cough after 6-7 days in children over 2
Zinc Lozenges
- 75 mg/day zinc, taken within 24 hours of symptom onset, can reduce cold duration (Cochrane evidence). May cause nausea and bad taste.
Vitamin C
- Regular supplementation may reduce severity and duration - worth trying individually
What Does NOT Work
| Treatment | Evidence |
|---|---|
| Antibiotics | Contraindicated - colds are viral; routine use is wrong for both adults and children |
| Oral corticosteroids | No evidence supporting use |
| Vaccines (for cold specifically) | No effective vaccine for common cold viruses |
| Garlic supplements | Not proven effective |

Home Care Essentials
- Rest - stay home, avoid spreading the virus
- Drink plenty of fluids - water, clear broth, warm soup; avoid caffeine and alcohol (dehydrating)
- Humidifier - may ease congestion and cough
- Steam inhalation - hot shower or steam bowl helps loosen congestion
When to See a Doctor (Red Flags)
Seek medical attention if:
- Fever above 39°C (102°F) or fever lasting more than 3 days
- Symptoms worsen significantly after initial improvement (possible bacterial superinfection)
- Severe sore throat (consider strep throat - needs a throat swab)
- Ear pain, facial pain/pressure (possible sinusitis or otitis media)
- Difficulty breathing or chest pain
- Symptoms lasting more than 10 days without improvement
- Immunocompromised, elderly, infant, or underlying cardiopulmonary disease (higher risk of complications)
Bottom line: Rest, stay hydrated, use ibuprofen or paracetamol for fever and throat pain, try saline nasal rinses, and consider zinc lozenges early. Avoid antibiotics. Most people feel significantly better within a week.
