What is the Difference Between Sinus Infection and Cold?
🆚 Go to Comparative Table 🆚The main difference between a sinus infection and a cold is the duration of the symptoms and the cause of the infection. Here are the key differences:
- Cold: A cold is a viral infection of the upper respiratory tract and is caused by one of over 200 cold-causing viruses. Symptoms usually peak within the first few days and then start to improve. Cold symptoms can linger for 10 to 14 days.
- Sinus Infection: A sinus infection, or sinusitis, is inflammation in the space behind the nose and can be caused by a viral or bacterial infection. It often develops after a viral cold or, in rarer cases, after a bacterial infection. Symptoms of a sinus infection may be more severe and can last for 4 weeks or longer.
Some ways to differentiate between a cold or viral sinusitis and a bacterial sinus infection include:
- The symptoms of a cold or viral sinusitis traditionally begin to improve after three to five days.
- The symptoms of a bacterial sinus infection tend to last longer than 10 days without improving.
- A cold that starts to improve after a few days but suddenly rebounds and becomes worse may indicate an infection that has turned into a bacterial sinus infection, a phenomenon called "double worsening".
Treatment for sinusitis can be similar to that of a cold, but if the cause is bacterial, a person will need antibiotics. It is essential to consult a healthcare professional if the symptoms persist or worsen.
Comparative Table: Sinus Infection vs Cold
Here is a table comparing the differences between a sinus infection and a cold:
Symptom | Sinus Infection | Cold |
---|---|---|
Duration | Can last up to 10-12 days or more | Symptoms typically peak around days 3-5 and then improve over the next few days |
Nasal Discharge | Thicker, yellowish, or greenish discharge | Clear or whitish discharge |
Facial Pain | Aches and pains in the facial area | Mild headache |
Congestion | Congestion or difficulty breathing | Stuffy nose |
Cough | Coughing | Coughing from postnasal drip |
Sore Throat | Sore, scratchy throat | Sneezing |
Other Symptoms | Watery, sensitive eyes | Itching, watery eyes |
Sinus infections are usually caused by bacterial or viral infections, while colds are caused by viral strains such as rhinovirus, coronavirus, and adenovirus. The duration and intensity of symptoms can sometimes help determine whether a cold or sinus infection is present. Sinus infections typically last longer and have more consistent symptoms, while colds have peak symptoms around days three to five and then improve over the next few days.
