In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 711.
A sneeze in any direction is not good. A cow's sneeze can point to a risk to life. A sneeze made by a child, an old person, a sick person or one with a cold gives no result.
Simple meaning: A sneeze in any direction is not good. A cow's sneeze can mean risk to life. A child's sneeze does not count.
