Antibiotics are not necessary for the common cold.
The common cold is a
self-limited condition and can generally be managed at home.
What is the common cold, and what causes it?
The common cold is a self-limited contagious illness that can be caused by a number of different types of viruses. The common cold is medically referred to as a viral upper respiratory tract infection. Symptoms of the common cold may include
cough, sore throat, nasal congestion, runny nose, and sneezing. More than 200 different types of viruses are known to cause the common cold, with rhinovirus causing approximately 30%-35%
of all adult colds. Other commonly implicated viruses include
adenovirus, respiratory syncytial virus, and
parainfluenza virus. Because so
many different viruses can cause the common cold and because new cold viruses constantly
develop, the body never builds up resistance against all of them. For this
reason, colds are a frequent and recurring problem. In fact, children in
preschool and elementary school can have six to 12 colds per year while adolescents and adults typically have two to four colds per year. The common cold occurs most frequently during the fall and winter months.
The common cold is the most frequently occurring illness in the world, and it is a leading cause of doctor visits and missed days from school and work. It is estimated that individuals in the United States suffer 1 billion colds per year, with approximately 22 million days of school absences recorded annually. In the United States, the common cold is thought to account for approximately 75-100 million physician visits annually, with an economic impact of greater than $20 billion per year due to cold-related work loss.
The common cold, pinkeye, earache, and gastroenteritis are examples of conditions in which a fever may not be present. Instead of just considering fever, it's prudent to consider your symptoms and if you're unsure, err on the side of sparing your coworkers and call in sick or work from home. Remember that some people (who could be your coworkers), such as those undergoing chemotherapy for cancer, those who have chronic conditions, and pregnant women may be particularly vulnerable to complications if they catch your illness.
