The Common Cold

2. The Common Cold By Marcus Jeffries and Jessica Bower

3. Causative Agent • 50% of colds are caused by rhinoviruses • Coronaviruses cause about 20% of colds • 10% can be attributed to several other viruses • We build up immunity to these viruses with each cold, but there are so many different types its hard for our immune system to keep up

4. Signs/Symptoms • The common cold usually brings on a runny nose, sore throat, and coughing; all of which can last for two weeks. • Other symptoms include: watery eyes, mild headache, and mild body aches.

5. Diagnosis • The common cold isn't a particularly nasty condition but some circumstances may arise in which a doctor should be notified, such as: • A fever running higher than 100.4°F • Symptoms lasting for more than ten days • Symptoms aren’t relieved by over-the-counter medicines

6. Treatment • A vaccine isn’t really possible seeing as how many variants of the common cold exist. There are over 200 different agents that cause the common cold (each with different serotypes). • Since the common cold is produced by a virus, antibiotics are ineffective. • Symptoms can be relieved by cough suppressants and antihistamines, but this will not help recovery time

7. Complications • Rhino virus it thought to be an airborne virus • Through the air, it can cause infections in the upper respiratory tract and other complications such as laryngitis. • It is also thought that the likelihood of obtaining the rhinovirus increases with the following: • Colder weather • Close, indoor contact • Psychological changes
