STI and the STD definition

There are some people who don’t really know the difference between STIs and STDs. In the first case we are referring to an infection. This means that the person in question might be infected by a virus, bacteria or fungus, but he or she could not have any symptoms yet. On the other hand in case of the diseases there are obvious signs and symptoms of the disease. This could be the STD definition.

What Is An STDAccording to this, someone could have an infection, but not a disease. It is important to know the difference, because this is the reason for which there are so many people who have an STI, but they don’t even know about it.
