Rhonchi causes

INTRODUCTION

Wheezing is a common presenting symptom of respiratory disease in infants and children. One in three children experience at least one acute wheezing illness before the age of three years [1,2]. A nationwide survey performed in the United States between 1988 and 1994 showed that the prevalence for wheezing amongst 2 to 3 year olds was 26 percent and amongst 9 to 11 year olds was 13 percent [3-5].

Subsequent reports continue to show similar prevalence. In a 2007 survey in the US and Europe, a total of 9490 children aged one to five years were screened for respiratory symptoms [5].

Overall, 3077 (32 percent) reported recurrent cough, wheeze, or breathlessness in the preceding six winter months. The prevalence of these symptoms varied from 29 percent in Northern Europe to 48 percent in Southern Europe. The overall prevalence in the US was 27 percent.

A large worldwide study looking at older children showed a global prevalence of wheezing of 11.6 percent in children aged 6 to 7 years and 13.7 percent in children between 13 to 14 years of age [4].
