Types of Fungal Infections, Causes, and Treatments

Fungal infections are quite common in all individuals and occur externally on all skin regions of the human body as well as internally within the blood, the lungs, and other organs in the body.

Infections caused by a fungus will often be benign; however, there are cases in which fungal infections can spread and cause extensive illness.

In what follows, we’ll discuss the characteristics of a fungal infection and the signs and symptoms that can be seen. Further, we’ll discuss some different types of fungal infections and their derivatives, including potential treatments and preventative measures that can be utilized.

Characteristics of a Fungal Infection

A fungal infection, also described as mycosis, is the overgrowth of a fungus to the point of causing a significant inflammatory response in the surrounding area. Three areas of the body that are notable for fungal infections are the skin, blood, and lungs. Different fungal types will cause specific infections in these areas in particular circumstances.

The types of fungal infections found in the skin include ringworm, athlete’s foot, jock itch, and other yeast infections. Fungal skin infections are prevalent with the foot being the most common area to find this infection. Fungal skin infections are not life-threatening; however, they can result in moderate symptomatology.

The most common type of fungal infection of the blood is candidemia, otherwise known as invasive candidiasis. Candida is a common skin fungus, and there are various ways in which this fungus can infect the blood. This process can result in severe infection and sepsis, which can lead to the risk of death. 

Finally, the types of fungal lung infections include aspergillosis, histoplasmosis, and pneumocystis pneumonia.

Causes and Symptoms of Fungal Infections

Fungal infections can occur due to environmental conditions and can occur by direct contact with a fungus or airborne transmission of a fungus. Differing types of fungi are found in certain environments. A few examples of fungi that can cause infection include candida, Blastomyces, cryptococcus, coccidioides, and Histoplasma.

While anyone can contract a fungal infection, those that are at greatest risk include individuals with decreased immunity secondary to genetics or poor health and individuals who live in some areas of the world where fungi are environmentally prevalent.

Different symptoms occur with different types of fungusSymptoms of fungal infection can often start as very mild, but then they subsequently worsen. This moderate progression can lead to severe fungal infection if untreated. 

In contrast, those with a healthy immune system and a proactive approach towards the rapid identification of symptoms will likely seek help in a more timely manner leading to much better outcomes.

Fungal infections in the blood and the lungs will require intravenous antifungal medication for treatment. In most recent years, the antifungals called echinocandins have been the most widely used, along with oral antifungal agents such as fluconazole.

Being aware of the environmental areas where the transmission of fungal illness is high can also help prevent this illness. The most suitable treatment for fungal infections will often be topical antifungals or oral antifungal therapy. It’s important to use the medication for the prescribed length of time to avoid the recurrence of fungal infection.
