Laryngitis is defined as an inflammation of the laryngeal mucosa, the organ responsible for giving way to inspired and expired air. It is the most special area for phonation, because the vocal cords are found there.
According to experts from the Spanish Society of Otorhinolaryngology (SEORL), this pathology is considered acute if normality is restored after a short period of time (hours or days). In case the symptoms last for more than three weeks, we will be dealing with cases of a chronic nature.
As we will see, laryngitis is a very common disease, in most cases of viral origin. That is why knowing its causes and symptoms is essential. Here we show you everything you need to know about it.
How is it distributed in the population?
Knowing the epidemiology of laryngitis, that is, who it affects and what is its prevalence (number of infected in a given population), is essential to address it. Epidemiological studies provide us with a series of data of special interest:
- Acute laryngitis accounts for 15-20% of respiratory diseases.
- The incidence in infants is 3 to 6%. That is, approximately 6 out of 100 people under the age of six suffer from this pathology in any given period of time.
- The typical profile of the affected person is a two-year-old male who suffers from the disease during the fall and winter.
- Acute laryngitis has a clear family component, since according to pediatric magazines, children with relatives who have suffered it are three times more likely to present it.
As we have seen, we are facing a pathology that predominates in children’s environments. This is due to the fact that up to six years of age, young children have a higher glottis and looser and less fibrous submucosal tissues, factors that predispose to infection.
