What are the symptoms of diphtheria?
Diphtheria starts with a sore throat, mild fever (101 degrees or less), and chills. Next, it can cause a thick coating in the back of the nose or throat. The coating may be white or grayish and makes it hard to breathe or swallow.
Is it serious?

Diphtheria can be very serious. **In children younger than 5 years old, as many as 1 out of 5 children who get diphtheria dies**. About 1 out of 10 people who get diphtheria dies.
The coating in the back of the nose or throat can get so thick that it blocks the airway, so the person can’t breathe.
The diphtheria toxin, caused by strains of bacteria called Corynebacterium diphtheriae, can affect the heart, causing abnormal heart rhythms and myocarditis (damage to the heart muscle). It can also cause nerve damage.
How does diphtheria spread?
Diphtheria bacteria spread when an infected person coughs or sneezes. A person who does not receive treatment can spread the bacteria for about 2 weeks after infection.
