Fungal Infections: Types, Symptoms, Causes and Prevention


Every individual once in their lifetime may have dealt with a Fungal Infection in some or other parts of the body. These infections are a part of fungi growth, perhaps the harmful fungi that thrive on different body parts due to numerous external and internal factors. Most of the fungi that are difficult to kill often invade the body parts, grow, and then re-infect the individual to survive. Some fungal infections are mild and they may disappear on their own, whereas others may display symptoms and survive for long, or until treated. 

What are Fungi? What is a Fungal Infection?

Before getting into the types of Fungal Infections that commonly affect humans, let’s first understand Fungi in brief:

Fungi are diverse groups of microorganisms that thrive in various environments, from air, soil, and plants to animals and humans. These microorganisms, called chitin, are hidden in the cell walls and include yeast, mold, and mushrooms.

What are Fungi

Some fungi are known for their beneficial role, like decomposing matter and aiding the nutrient cycle; others, when invading the body, can lead to numerous health issues. When these microorganisms (Fungi) invade the body, they multiply, affecting different body parts and leading to various kinds of infections. These infections can commonly affect the skin, mucous membranes, respiratory tract, and sometimes even nails. 

Are there Types of Fungal Infections?
