Dreams about health concerns, especially involving loved ones, often reflect our subconscious worries and feelings about their well-being. In your dream, mentioning a virus inherited from your ex-husband could symbolize unresolved feelings or concerns about your past relationship and its impact on your children.

The idea of a "cure" and an "examination" might represent your desire to seek clarity or solutions for issues that may be affecting your family. It could also signify a hope for healing and understanding in your relationships, both with your children and your ex-husband.

Consider reflecting on any current anxieties or situations in your life that relate to your family dynamics or health. This dream may be encouraging you to address these feelings openly, either through communication or by seeking help if needed. It’s important to ensure that you’re taking care of not only your children’s needs but also your own emotional health.
