There are many mites and parasites that can invade the skin and cause serious and contagious skin rashes. In addition,certain funguses can do the same thing. Most of these contagious skin rashes can have very serious side effects if they are not treated in a timely manner. This of course is not to mention the fat that we are discussing contagious skin rashes which means that anyone who comes in contact with the afflicted can become affected by the rash. This makes these types of skin rashes all the more dangerous. This is especially true if there are babies or small children present. One of the most noted of the contagious skin rashes is that of ringworm. This is a fungal infection that is spread quite easily from person to person. Typically this skin rash starts with a school age child but can quickly move throughout the household if the fungus us not killed. Usually the preferred treatment for this type of infection is Tinactin or some other form of an anti-fungal. Typically once the cream has been applied several times the rash becomes less contagious. You can generally tell when the treatment is working as the raised skin will begin to go down and there will be some drying and peeling present.
Any skin infection that is oozing liquid should be considered possibly contagious until doctor rules this out. There is always a chance that a skin rash may not be contagious but it is best to treat it as such until you are absolutely sure. After all,as they say it is better to be safe than sorry. You would not want to begin having something horrid transmitted all throughout your household,especially if you have several children. If you work in a school environment and notice a child could have a skin rash that looks as though it might perhaps be contagious then you should call the parents right away and have them to get that child. It is best top have a doctor write a note clearing that child to come back to school than to have an epidemic on your hands at a school full of young children. In situations where contagious skin rashes do travel through schools it is usually very hard to get rid of the problem. This is why it is always better to try to err on the side of caution. It would be better to call out a false alarm than to do nothing and allow something contagious to become a major problem.
