Which Determines the Number of Common Warts?
As said above, not everyone who contacts the viruses develop common warts. In those who have them, the number is also not the same. Experts are not sure about the underlying cause, but they suggest that some would have stronger immune systems that can fight off the foreign invaders better and prevent those warts from occurring. People with higher likeliness to poison ivy can be more vulnerable to the problem. Also, it is not uncommon to see common warts on different siblings in a family. [4]
