Sneezing is a natural reflex of the body to overcome cold or allergen factors. When you have a cold, have tissues on hand all the time.
Cover your mouth and nose with a tissue
The best way to prevent the spread of the germs when you sneeze is to cover your mouth and nose with a paper tissue.
If the sneeze is loud and repeatedly, then quickly excuse yourself, leave the room, and head to the restroom—return after you blew your nose and washed your hands.
Sneeze into the crook of your elbow or upper sleeve
Sometimes, a sneeze can get you by surprise and unprepared with a napkin or handkerchief on hand. In this situation, sneeze into the crook of your elbow or upper sleeve to minimize the effect and say “excuse me” afterward.
Never sneeze into your hands
Maybe, later on, you will have to hold a paper and pass it on to somebody else or make a handshake at the end of the meeting.
Remember to be always courteous and show consideration and understanding to the people around you. Sometimes a simple gesture can have a more significant impact than a dozen words.
