Fungi Fungal infections can occur anywhere, not just the tropics or high school locker rooms. Fungi tend to thrive in warm, moist environments, and many strains do exceptionally well in human skin. The rash will appear to be a pale area surrounded by a slightly puffy, reddish border. Again, the solution to clearing up fungal infections is fairly straightforward. Avoid scratching the rash, because bacteria do quite well in the already-compromised area of a fungal infection.
Bacterial infection is an altogether nastier situation requiring antibiotics.
Skin infections A skin infection is a much more serious proposition than all of the above. Beginning at an inadequately cleansed break in the skin, such as a cut or scrape, the infection will look like a series of reddish tracks, usually growing away from the cut. You will also feel a sensation of heat in the cut and probably notice swollen glands under your armpits or inner thighs. All of these are a dead giveaway for infection that must be taken seriously. Get to a doctor.
