Insights

Fungal infections in Portugal cause over 1.6 million infections annually, with skin and nail conditions being most common. This study estimates the burden of various fungal diseases, including candidiasis and aspergillosis, to improve understanding of their epidemiology.

Area of Science:

  • Medical Mycology
  • Epidemiology
  • Infectious Diseases

Background:

  • Fungal infection epidemiology is poorly understood globally due to a lack of mandatory reporting.
  • Portugal's specific burden of fungal diseases has not been comprehensively estimated.
  • This study contributes to a global initiative to quantify the impact of fungal diseases.

Purpose of the Study:

  • To estimate the annual incidence and prevalence of fungal infections in Portugal.
  • To identify the most common fungal diseases and populations at risk.
  • To provide data for public health strategies and resource allocation for fungal disease management.

Main Methods:

  • Systematic review of published epidemiological data on fungal infections in Portugal.
  • Estimation of national incidence/prevalence using data from at-risk populations where direct data was absent.
  • Inclusion of common fungal infections like skin/nail infections, candidiasis, aspergillosis, and Pneumocystis pneumonia.

Main Results:

  • An estimated 1,695,514 fungal infections occur annually in Portugal.
  • Skin and nail fungal infections are most prevalent, affecting approximately 1,510,391 individuals yearly.
  • Other significant burdens include recurrent vulvovaginal candidiasis (150,700 women), candidemia (231 cases), and fungal-related asthma complications (16,614 severe asthma with fungal sensitization).

Conclusions:

  • Fungal infections represent a substantial public health issue in Portugal, with a high annual burden.
  • Targeted interventions and improved surveillance are needed, particularly for common conditions like skin/nail infections and vulvovaginal candidiasis.
  • Further research into the epidemiology of less common but severe fungal infections like invasive aspergillosis and Pneumocystis pneumonia is warranted.

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Fungal Group Zygomycota

Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...

Fungal Phylum Basidiomycota

Basidiomycota is a diverse phylum of fungi that includes ecologically significant decomposers such as white rot fungi, symbionts like mycorrhizal fungi, plant pathogens such as rusts and smuts, and edible species like Agaricus bisporus (the common button mushroom). These fungi play crucial roles in nutrient cycling, symbiotic relationships, and even human health. Their defining feature is the basidium, a microscopic club-shaped structure responsible for producing basidiospores.Fruiting Bodies...

Fungal Phylum Ascomycota

Phylum Ascomycota, a major division within the subkingdom Dikarya, comprises a diverse range of fungal species, including both unicellular yeasts and filamentous molds such as Aspergillus and Penicillium. These fungi thrive in a variety of habitats, from aquatic ecosystems to terrestrial environments, playing crucial ecological and economic roles.Morphology and ReproductionThe defining characteristic of Ascomycetes, commonly referred to as sac fungi, is the ascus—a sac-like structure that...

Overview of Fungi01:29

Overview of Fungi

Fungi are a diverse group of eukaryotes more closely related to animals than other eukaryotes. Fungal cell walls comprise chitin, a polysaccharide that provides structural strength, and glucans, which contribute to flexibility and integrity. Other polysaccharides, such as mannans and galactosans, may supplement or replace chitin in some fungi. These adaptations, along with their preference for acidic environments and tolerance for high osmotic pressure, enable fungi to thrive in various...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
