Viral
sinusitis is extremely common. The exact number of
cases is very difficult to estimate because many cases are not reported to
health professionals and because health professionals do not all define the
illness the same way.
Sinusitis sometimes develops after a common cold. Children get about 6 to 8 colds a year. Adults get an average of 2 to 3 colds a year. Less than 2 out of 100 colds will develop into sinusitis.1
People develop sinusitis more often in the fall, winter, and
spring.
Although not a serious health problem, sinusitis leads to a high
number of doctor visits, missed school and work days, and antibiotic
prescriptions, all of which result in high medical costs. Prompt and
appropriate treatment of colds and early sinus infections may help avoid
complications, long-term (chronic) problems, and the costs that come with
them.
