Can you have a yeast infection and not know it?

Yes, it is possible to have a yeast infection and not know it. Some people who have yeast infections do not experience any symptoms, or their symptoms may be mild and easily mistaken for other conditions. In some cases, people with asymptomatic yeast infections may still be able to spread the infection to others. For this reason, it is important to get tested for a yeast infection if you have any concerns about having one.
