Tussaphobia

Tussaphobia (from Latin tussis, meaning "cough"), or pertussaphobia (from Latin per, "thorough") is the fear of coughing. This fear is often caused prototypically by coughing, especially when coughing constantly when ill. Another causes include not-so-pleasant sound of coughing, by oneself and by others. Sufferers would try to avoid coughing especially by taking cough medicine even when not coughing and avoid suffering illness that may lead to coughing by taking medicines. They would dread or panic if they cough and would flee from people who cough.
