What you have to keep in mind is that a yeast infection is contagious, but not to the extend that, for instance, a cold is. One cannot ‘catch’ a yeast infection the way you would get a common cold. There has to be direct contact with the spores of the Candida fungus for you to get a yeast infection from someone.
This is important. Spreading your yeast infection to others can be prevented by good hygiene. Maybe a little more than good! Make sure toilets are cleaned thoroughly, at least once a day. It is also important to make sure all cloths and bucket that are used for cleaning are rinsed very well to make sure that all cleaning liquid is washed away.
Another thing to be cautious about is, never take a bite of food from someone else’s spoon or fork. Do not eat a baby’s that has a yeast infection in the mouth’s leftovers! So many people do that and it is fatal for spreading the yeast infection.
Yes, yeast infection is contagious under certain circumstances, but you can prevent it with a few common sense precautions. You can read more about it on Yeast Infection Contagious.
