There is no escape...believe it or not. Mathematics is everywhere.
Subhashree, I wonder if we can learn something about your question from other phobias. Here's an abstract about Spider Phobia, that concludes "The latter finding may indicate, that the acquisition of spider fear is facilitated by specific parental disgust reactions when confronted with spiders." Here's an online science paper about Fears and Phobias of Snakes. That paper mentions that (i) parental influences lead to phobias in their children. (ii) People of all ages can develop fears because of traumatic experiences. These references are not directly relevant to mathematics education, but sometimes lateral thinking helps us to look at our problems in new ways. Do you use the word "phobia" to dramatise your question, or do you believe that many students have a real fear of mathematics?
