What is Impetigo?
Impetigo is a highly contagious skin infection that is caused by staphylococcus (staph) and streptococcus (strep) bacteria. It is most common amongst children aged between 2- 6 years than adults. This skin infection may often start as a minor scratch or appear as a red sore on the upper lip – similar to a cold sore or fever blister.
It then forms a blister that ruptures and secretes to form a yellowish-brown crust. Impetigo is spread by direct contact to others from sharing towels, clothing, toys and other personal items. These sores may also spread to other parts of the body including the face or hands as well as to other people from scratching or touching.
There are types of impetigo, non-bullous and bullous impetigo. Non-bullous impetigo is the most common form and is caused by staphylococcus and streptococcus bacteria. It is characterized by tiny blisters or scabs that form yellowish-brown crusts. Bullous impetigo is caused by staphylococcus bacteria which produces toxins that cause breakage in the skin.
The symptoms and signs of non-bullous and bullous impetigo include:
- Affects the nose, face, arms, and legs
- Appears as small blisters or scabs
- Forms yellow or honey-colored crusts
- Appears in various skin areas such as buttocks
- Blisters leave red, raw skin with ragged edge
What Causes Impetigo?
Impetigo is caused by two types of bacteria, Staphylococcus aureus (staph) and Streptococcus pyogenes (strep). Both types of bacteria are known to thrive wherever there is close contact with large groups of people, particularly in schools or daycare environments. Staph and strep bacteria are harmless until they enter through a wound and cause an infection. Children are more likely to develop impetigo through a cut, scrapes, burns or insect bite or if the skin has already been irritated by other skin problems such as eczema, poison ivy, chicken pox or allergies. Impetigo in adults comes about as a result of injury to the skin, also by skin conditions such as dermatitis.
Risk factors include:
- Poor hygiene habits
- Direct contact with a person who has impetigo
- Using personal items such as towels, linen or clothing of a person with impetigo
- Chronic dermatitis
- Crowded conditions
- Participation in skin-to-skin contact sports such as football
- Warm, humid weather
- People with diabetes or a compromised immune system
If your child develops sores or blisters, consult your doctor for a proper diagnosis. Your doctor may remove a bit of material from the sore with a cotton swab to have it tested for the presence of bacteria.
Help for Impetigo
The treatment for impetigo depends on the type of impetigo, the severity of the condition and the age of your child. Treatment options include topical and oral antibiotics as well as certain hygienic measures. Minor cases of impetigo may be treated by simply cleaning the wound – wash the wound two to three times a day with mild soap and water.
Soak stubborn crusts in warm water or compress them with a saline solution before applying topical antibiotics. Parents should ensure that the child’s fingernails are cut short to avoid scratching of the affected area. Topical antibiotics such as Bactroban may be applied to the skin to treat the infection. If the infection is widespread or slow to respond to the ointment, oral antibiotics are administered.
Natural and holistic treatments are also extremely effectively in relieving the symptoms of bacterial infections. Herbal and homeopathic remedies are safe to use without the harsh side effects of prescription drugs, and best of all they maintain overall physical and emotional health.
Herbs such as Hypoxis Rooperi (extract of African Potato), Agathosma Betulina (also known as buchu) and Mentha Piperita help to boost and strengthen immune system functioning. A combination of herbal and homeopathic ingredients such as Natrium muriaticum, Kalium muriaticum, Galium aperine (Cleavers) and Trifolium pratense (red clover) helps to balance and hydrate the skin and promote the natural process of skin healing.

Tips to prevent impetigo
Preventing injuries, treating infection and practicing good, clean hygiene is important if you want to avoid impetigo. Follow these precautionary measures:
- Wash hands thoroughly and frequently – after using the bathroom, before cooking and eating, playing with pets and cleaning or dressing a wound
- Ensure that each family member has his or her own toothbrush, washcloth and towel
- Separate the infected person's bed linens, towels, and clothing from those of other family members, and wash these items in hot water
- Teach your child not to share personal items such as eating utensils, clothes, towels, toothbrushes or lip balm with other children
- Clean and treat injuries with mild soap, antibacterial ointment and then cover with gauze
- Practice good personal hygiene by showering or bathing everyday, washing your child’s hair and trimming his or her nails regularly
- Teach your child not to scratch or pick scabs, wounds or sores as the area under the nails breeds bacteria
- Keep your child at home until the infection has healed
