Sternutaphobia

Sternutaphobia (from Latin sternutatio, "sneezing") is the fear of sneezing. People with sternutaphobia will try to avoid sneezing; if they sneeze they dread or panic often with rapid breathing or heart palpations. Sufferers may often fear illnesses also since sneezing often put germs into the air for others to breathe in and get sick, so they would walk away from people who are sneezing.
