The "Hygiene Hypothesis" suggests declining childhood infections increase allergy prevalence. This study examines the link between reduced infections and rising allergic diseases, exploring the underlying pathophysiology.
Area of Science:
- Immunology
- Epidemiology
Background:
- Allergic diseases have increased significantly in recent decades, particularly in high-income, urban areas.
- Environmental factors like pollution and nutrition show limited association with allergy prevalence.
- A decline in childhood infections is strongly correlated with increased allergy rates, forming the basis of the
Purpose of the Study:
- To investigate the pathophysiology behind the rise in allergic diseases.
- To critically evaluate the
Main Methods:
- Review of epidemiological data on allergy prevalence.
- Analysis of the immunological impact of microbial exposure in early life.
- Exploration of the
Main Results:
- Childhood infections and microbial antigen exposure show a negative correlation with allergy development.
- The
Conclusions:
- The decline in childhood infections is a significant factor in the increasing prevalence of allergic diseases.
- Further research is needed to fully understand the complex pathophysiology and validate the

Infection
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
