Infantigo is a disease in which red colored scars appear on skin. It occurs as a result of a bacterial infection. It is a highly contagious disease and readily spread on direct contact. It most commonly occurs in kids and rarely occurs in old age person. The chances of occurrence are high in children less than 2 years. It is also known as preschool rash.
It occurs due to a bacterial infection and the bacteria involved are streptococcus and staphylococcus species of bacteria. In this disease red colored scars appear on skin in the form of round circles. In fact these are not just scars but these are blisters which occurs on skin surface. These blisters are filled with fluid or pus. This fluid or pus is rich in causative bacterial species. Initially red spots are formed in the form of clusters on skin. And then it start developing in to blisters. These blisters start producing fluid in them.
This fluid makes it red in color. Whenever the fluid from these blisters ooze out or these blisters get burst, the fluid spreads on skin surrounding these blisters. These red sores or blisters are not painful. Patient feels itching and irritation on skin which makes patient to rub aggressively. Patient should avoid rubbing and scratching on these blisters. As excessive rubbing or scratching will burst blisters and the fluid will come out of them. Fluid will spread around will lead to the formation of new blisters or sores.

- Skin turns red in color.
- Sores have a defined boundary.
- Boundary is made of red colored small spots. These spots are present in the form of clusters.
- Blisters are fully filled with fluid or pus.
- These blisters get burst or the fluid oozes out of these blisters and spread around.
- When fluid comes in contact with skin, it causes irritation and itching on skin.
- This fluid or pus leads to the formation of yellow colored scabs.
- Yellow scabs may become permanent if treatment does not start on time.
Infantigo usually occurs in children with age less than 2 years. Kids are more prone to this disease because their immune system is weak and under development so bacteria readily grow inside their body. Baby skin is very soft and delicate with thin upper most layer of skin. So chances of lesions on baby's face are higher as compared to adults. Usually it starts from chin or area around mouth. It also occurs on other body parts like legs, arms and stomach.
It occurs on neck region rarely. The bullous type of infantigo mostly affects arms in adults. In adults, erosion occurs on the top most skin of arms. On legs, the area around inner thighs and lower calf more readily develops red sores and blisters. Sports man wearing shorts more commonly develop red sores on their lower calf.
