Understanding skin infections is important for overall health and well-being, as they can lead to discomfort and serious complications if left untreated. These infections can be caused by bacteria, viruses, fungi, and parasites, with some of the leading causes of skin infections being poor hygiene, low immunity, and skin disorders.

The main categories of skin infections are bacterial skin infections like staphylococcal infections, viral skin infections like herpes simplex, fungal skin infections like dermatophytosis candidiasis, and parasitic skin infections like scabies. Thus, knowing the types of skin infections, their causes, and their symptoms will help to prevent infections and seek treatment in case of an outbreak.

What are the Types of Skin Infections?

The following are four different types of skin infections:

1. Bacterial Infections
2. Viral Infections
3. Fungal Infections
4. Parasitic Infections

1. Bacterial Infections

• Staphylococcal Infections: Staphylococcal infections are diseases caused by staph bacteria. These germs commonly dwell in the skin and nasal passages of the human body among healthy carriers. Most of the time, they are asymptomatic or result in skin diseases that are not very dangerous. The management of such conditions mainly requires antibiotics and surgical evacuation of the infected area.
• Streptococcal Infections: Types of skin infections associated with streptococcal bacteria are cellulitis and erysipelas. The doctors prescribe antibiotics to the patient for the infections most of the time. Some of the preventive steps include proper washing of the body, while any broken skin ought to be covered adequately.
• Impetigo: Impetigo is a bacterial skin disease that affects mostly children through contact. It looks red with blisters and later becomes tingling, with sore spots encrusted with a honey-coloured scab. Its treatment aims at the use of topical or oral antibiotics. It can be eliminated by observing personal hygiene, where one has to wash their hands frequently, cut their nails short, and not touch areas infected with the disease.
• Cellulitis
• Boils and carbuncles
• MRSA
• Syphilis
• Tuberculosis
• Leptospirosis

2. Viral Infections

• Herpes Simplex: The Herpes simplex virus then causes painful blisters or ulcers on the skin and mucous membranes of the lips, mouth, and other body parts, cold sores, and genital herpes. Antiviral drugs can treat this and reduce the signs of the disorder. Cross-transmission can be avoided by avoiding direct contact with a person, using barriers, etc.
• Chickenpox: Chickenpox results from the Varicella zoster virus. It manifests itself through the formation of a rash area with red spots and a blister. It is caused by coming in contact with an infected person or by/with contaminated objects. The treatment mainly includes antihistamines and calamine lotions.
• Shingles: Like chickenpox, shingles is caused by the Varicella zoster virus. However, it only affects people who have had chickenpox before. The symptoms manifest as a painful rash that becomes vesicles and mainly appears on one side of the body. Major prescribed therapies include antiviral drugs and pain relief. The vaccine against shingles is available and recommended for everyone above 50 years of age.
• Warts
• Measles
• Hand, foot, and mouth disease
• Mpox

3. Fungal Infections

• Athlete's Foot: Athlete's foot is a fungal infection which manifests on the feet. Symptoms include itching, a burning sensation, and cracked skin on the soles and between toes. Treatments for this condition include applying antifungal creams or powders. Preventive measures include dried feet, wearing shoes that do not lock out moisture, and avoiding walking barefoot in public places.
• Ringworm: Another fungal infection is ringworm. Its symptoms include red, itchy skin with ring-shaped rashes accompanied by scales. Ringworm can occur on any site of the body. Topical and systemic antifungal creams might also be used in more serious cases. Preventive measures include washing hands, avoiding exchanging clothes, bedding, and towels, and ensuring the skin is kept as dry as possible.
• Candidiasis: Candidiasis manifests in the mouth, genital parts, and skin folds. Among the symptoms are inflammation, itching, rash on the skin and a white coating in the mouth and the patient is also advised about the measures to follow concerning health hygiene and consult a dermatologist doctor for treatment.
• Ringworm
• Nail fungus
• Oral thrush
• Diaper rash

4. Parasitic Infections

• Scabies: Scabies is a disease caused by Sarcoptes scabiei, which resides on the skin of patients. The mites lay eggs on the surface of the skin, thus further spreading the disease. This results in itching, characterised by intense rashes that resemble pimples. Some areas usually affected are wrists, elbows, armpits, waist, palms, and between the fingers. The disease is passed through direct skin-to-skin contact. Treatments include topical creams or lotions prescribed by a doctor and oral medication in severe cases. Preventive measures include avoiding close contact with the infected and ensuring personal items, including bed linen and clothes, are washed and dried at high temperatures.
• Lice Infestation in the Head: Head lice are tiny, parasitic insects that feed on human blood on the scalp, creating an itching sensation. They are directly communicable through head-to-head contacts, so the at-risk groups are children in schools and those attending preschool childcare. It can be treated using a prescribed shampoo or lotion that contains the insecticides permethrin. Treatment involves a stricter regime of killing and removing the lice with the help of a fine-tooth comb. Prevention consists of avoiding sharing items that can easily get contaminated, such as combs, hats, pillows, etc.
• Bedbugs
• Cutaneous larva migrans
