There are many skin problems popular these days. While some of them are contagious like scabies, and other are not. Impetigo is one such disease which is not only transferable, but also very dangerous. It needs to be addressed medically as soon as it is identified. Moreover, having a definitive diagnosis for this problem is not an easy task.
Hence, here are the details about the symptoms and causes:
What are the symptoms of impetigo?
First thing you need to know is that- impetigo symptoms can be highly painful and embarrassing. Especially, when these occur on the face, situation can be worse. As far as the symptoms are considered, it can vary slightly from type to type. However, they are some similar ones, including;
- Skin lesions
- Itchy rashes
- Swollen lymph nodes
- Fluid filled blisters
- Red sores, which might leave a yellow crust
What causes impetigo?
As stated in the beginning, impetigo is caused by two types of bacteria, namely:
- Staphylococcus aureus
- Streptococcus pyogenes
Staphylococcus aureus: This bacterium produces a toxin which further leads impetigo to spread to nearby skin. Actually, the toxin attacks a protein that keeps skin cells bound together. When this protein is damaged, the bacteria can spread rapidly. Now there are two ways the infection spreads out;
- Primary impetigo: When the bacteria invade the skin through insect bite, cut, or other lesion on normal skin, it is termed to be primary one.
- Secondary impetigo: In this case, the bacteria invade the skin through some other skin infection or condition like eczema or scabies.
The common thing between both the types of bacteria is that these exist harmlessly on the human skin. It will cause infection when a cut or wound is found. Usually, impetigo is found in adults after a cut, scrape, or insect bite. However, in case of small children, their skin may also become infected without any apparent skin damage.
Do you know a healthy person can become infected just by touching things which were earlier in contact with an infected person? Yes, it can be anything like your bed, towels, toys, attires, linen, and so on.
Here, it is important to note that symptoms might not appear until 4 to 10 days, after initial exposure to the bacteria. But there are good chances that during those days, people might pass the infection on to others, without knowing that they are infected. Therefore, experts say that children are more likely to become infected. As their immune systems are not yet fully developed, it takes greater time for the symptoms to appear.
Hence, it is important for the parents to keep an eye on their children if they ever get in contact with someone already infested with impetigo!
