2. Airborne Droplets
When a person who is infected with diphtheria sneezes or coughs, it can release a mist of droplets that are contaminated. When this occurs, people who are located nearby may inhale C. diphtheriae bacterium. This is one of the fastest ways that diphtheria can spread, especially in situations that are crowded.
Good hygiene, such as covering up when you sneeze or cough is important when it comes to containing this disease. However, in large group situations, it can be nearly impossible to contain the bacteria. This is one of the reasons that it is important to make sure that you are vaccinated against this disease.
The vaccination can greatly lower your risk of developing diphtheria. The vaccination also prevents outbreaks of this illness and is the reason why there are far fewer cases of this illness than in years past. Although outbreaks still do occur.
