Diphtheria is a life-threatening infection that spreads easily. The infection most commonly attacks the tonsils, throat, and nose.
Diphtheria is a medical emergency that requires immediate care from your doctor. Not everyone who gets diphtheria shows signs of illness, though they may be able to infect others. The sooner it is treated, the better the outcome will be.
Despite availability of vaccines for prevention of diphtheria, cases of diphtheria are on the rise.
Diphtheria is caused specific bacteria. The infection spreads from person to person through contact with: Droplets of moisture that are coughed or sneezed into the air by an infected person and breathed in by a non-infected personPersonal items, such as tissues or drinking glasses, that have been used by an infected personSkin that is infected with diphtheria
Factors that increase your chance of getting diphtheria include: Having never been immunized against diphtheriaNot having had a booster dose in the past ten yearsHaving a compromised immune system
Signs and symptoms of diphtheria usually begin 2 to 5 days after a person is infected. The most obvious sign of diphtheria is a gray covering on the back of the throat. The covering can detach and block the airway. If left untreated, the bacteria can produce a poison that spreads through the body causing damage to the heart, nerves, and kidneys.
Symptoms include: Sore throat and painful swallowingFever up to 103°FGray covering on the back of the throatCough, possibly a barking coughSwollen glands in the neckDifficulty breathingDifficulty swallowingWeaknessSkin infection

Your doctor will ask about your symptoms and medical history. A physical exam will be done. Diphtheria will be suspected if the throat and tonsils are covered with a gray membrane.
Your doctor may need to test to confirm the diagnosis. This can be done by collecting
a swab for culture or
a tissue sample.
Talk with your doctor about the best treatment plan for you. If your doctor suspects diphtheria, your treatment will start right away, even before the lab results are returned. Treatment options include the following: Antitoxin injectionAntibioticsIsolation and bedrest
The vaccine for diphtheria is safe and is effective at preventing the disease. All children with few exceptions should receive the DTaP
series. This protects against
. A single dose of Tdap vaccine is recommended for children aged 11 years or older, even if they did not receive the DTaP. A booster should be administered every 10 years after, or after exposure to tetanus if necessary.
If you or your child has not been fully vaccinated, talk to their doctor. There are catch-up schedules available.
