Diphtheria
Condition
Definition
Diphtheria is a serious bacterial infection that can result in heart, nerve, and kidney damage. It can be deadly if it is not treated right away.

- Inhaling bacteria after a person coughs or sneezes
- Using personal items such as tissues or drinking glasses
- Having skin contact
Risk Factors
Things that raise the risk of diphtheria are:
- Never being vaccinated for diphtheria or not having a booster dose in the past 10 years
- Having a weakened immune system

They may include:

Treatment includes:
- An antitoxin to stop damage to the body
- Antibiotics to treat the infection
- Isolation and bed rest
Prevention
Staying up to date with the diphtheria vaccine can prevent the infection.
