Those who did not have measles in childhood (or did have had atypical measles, without a rash, similar to post-vaccination "measles-like symptoms"), in adulthood had an increased risk of:
1) immunoreactive diseases (autoimmune diseases due to an infectious disease),
2) skin diseases (dermatitis, eczema, etc.),
3) degenerative diseases of the bone and cartilage (osteoarthrosis, etc.),
4) oncological diseases.
Initial analysis of 10 articles (for a meta-analysis). According to indirect markers, infectious diseases are associated with a 20% reduction of risk of dermatitis, 30% reduction of risk of allergic rhinitis and 40% reduction of risk of asthma.
