1. What is the difference between a cold and the flu?
Although the flu and the common cold are both respiratory illnesses, they are caused by different viruses. Because they have similar symptoms, it can be difficult to tell them apart. But generally, cold symptoms are much milder than flu.
Common cold symptoms include:
The flu, on the other hand, often causes higher fever, chills, body aches-=, and fatigue.
2. Why isn't there a cold vaccine?
The common cold can be caused by nearly 250 different viruses. It's just too difficult for scientists to prepare a vaccine that protects against all of the cold viruses. Also, there's less need for a cold vaccine. Colds are minor infections of the throat, nose, and sinuses. Colds generally come and go with no serious complications. You're miserable for a few days, then it's over.
3. Could my cold symptoms actually be allergies?
If you are sniffling, but not achy or feverish, you may very well have allergies. Also, if your symptoms last longer than two weeks, and you also have red, itchy eyes, the evidence points to allergies. However, it's often difficult to tell the difference between a cold and allergies, because people with allergies and asthma are more likely to get colds. They may already have inflamed and irritated lungs, so they are less able to fight off a cold virus.
4. What's the best treatment for a cold?
There is no cure for the common cold. The most important thing you can do is drink a lot of fluids to keep your body hydrated. This will help prevent another infection from setting in. Avoid drinks like coffee, tea, and colas with caffeine. They may rob your system of fluids. As for eating, follow your appetite. If you're not really hungry, try eating simple foods like white rice or broth.
Chicken soup is comforting, plus the steam helps break up nasal congestion. Ginger seems to settle an upset stomach. A hot toddy may help you sleep, but beware of mixing alcohol with other cold remedies.
