Causes: Colds are caused by one of hundreds of common viruses that can easily be transmitted from person to person.
Symptoms: Stuffed nose/congestion, runny nose, fever, headache, cough, sore throat or fatigue.
When to see a doctor: Colds can sometimes lead to other infections. If a cold lasts longer than 10 days, consult with your physician.
Prevention: Keep your distance from people who are coughing or sneezing. Drink a lot of fluids (water is best) and wash you hands often.
General treatment strategies: Since there's no cure for a cold, the best advice is to get plenty of rest and drink a lot of fluids, especially water to moisten mucus membranes. Make sure you have plenty of ventilation.
