Candidiasis is a condition caused by which type of infection?

1. Viral infection

2. Bacterial infection

3. Yeast-like fungal infection

4. Parasitic infection

The correct answer is: Yeast-like fungal infection

Candidiasis is indeed a condition caused by a yeast-like fungal infection, specifically by the fungus Candida, most commonly Candida albicans. This organism naturally exists in small amounts in the human body, particularly in the mouth, gut, and vagina, but when the balance is disrupted—by factors such as antibiotic use, hormonal changes, or a weakened immune system—Candidiasis can occur. The other types of infections mentioned—viral, bacterial, and parasitic—are caused by different pathogens with distinct characteristics and treatment protocols. Viral infections are caused by viruses, which replicate within host cells. Bacterial infections result from bacteria, which can cause various illnesses depending on their type and virulence. Parasitic infections are due to organisms that live on or in a host and may cause harm. Thus, understanding Candidiasis as a fungal infection helps in recognizing its unique treatment approaches, which often include antifungal medications, something that distinguishes it from the management of infections caused by other types of pathogens.
