The common cold
The common cold, also known
simply as the cold, is a viral infectious disease of the upper respiratory
tract that primarily affects the nose. It is also possible that the throat,
sinuses, and voice box get also affected. It is the most frequent infectious
disease in humans. The average adult gets two to four colds a year, while the
average child may get six to eight. They occur more commonly during the winter.
These infections have been with humanity throughout history.
Signs and symptoms
Signs and
symptoms may begin less than two days following exposure. They include
coughing, sore throat, runny nose, sneezing, headache, and fever. People usually
recover in seven to ten days. Some symptoms may last up to three weeks. In
those with other health problems, pneumonia may occasionally develop.
Cause
Well over 200
virus strains are implicated in the cause of the common cold; the rhinoviruses
are the most common. They spread through the air during close contact with
infected people and indirectly through contact with infected objects. Risk
factors include going to daycare, not sleeping well, and psychological stress.
Symptoms are mostly due to the body's immune response to the infection rather
than to tissue destruction by the viruses themselves.
Influenza versus the common cold
In the early
stages of infection, it can be difficult to distinguish between the common cold
and influenza. The latter is commonly referred to as the flu and is usually a
more severe disease than the cold. In fact, influenza is a mixture of symptoms
of common cold and pneumonia. Influenza patients may suffer from fever, body
aches, headache, diarrhea, sore throat, runny nose, vomiting, and fatigue.
Treatment of the common cold
There is no
vaccine for the common cold. The primary methods of prevention are the
following: hand washing; not touching the eyes, nose or mouth with unwashed
hands; and staying away from other sick people. Some evidence supports the
importance of using face masks.
No cure for the common cold
exists, but the symptoms can be treated. Nonsteroidal anti-inflammatory drugs
(NSAIDs) such as ibuprofen may help with pain. Antibiotics should not be used.
In addition, evidence from research does not support any benefit from cough
medicines.
