Diphtheria, a childhood disease that was common in the 1930s, is an acute bacterial disease that can infect the body in two areas:
- The throat, nose, and tonsils (respiratory diphtheria)
- The skin (skin or cutaneous diphtheria)
A vaccine against diphtheria has made it very rare today in the U.S. and other developed countries.
The diphtheria bacterium can enter the body through the nose and mouth. However, it can also enter through a break in the skin. It is transmitted from person-to-person in close contact by aerosol route (breathing in respiratory secretions or droplets that contain diphtheria bacteria from an infected person coughing, sneezing, or laughing). After being exposed to the bacteria, it usually takes two to four days for symptoms to develop.
The following are the most common symptoms of diphtheria. However, each child may experience symptoms differently. Symptoms may include:
The symptoms of diphtheria may resemble other problems or medical conditions. Always consult your child's doctor for a diagnosis.
A doctor can usually diagnose the illness based on clinical examination. A swab culture of the mouth or affected mucous membrane may also be used to confirm the diagnosis.
Specific treatment for diphtheria will be determined by your child's doctor based on:
- Your child's age, overall health, and medical history
- Extent of the condition
- Your child's tolerance for specific medications, procedures, or therapies
- Expectations for the course of the condition
- Your opinion or preference
Antibiotics are usually effective in treating respiratory diphtheria before it releases toxins in the blood. An antitoxin can be given in combination with the antibiotics, if diphtheria is suspected. Sometimes a tracheostomy (a breathing tube surgically inserted in the windpipe) is necessary if the child has severe breathing difficulties.
Children in the U.S. are routinely given a triple vaccine (DTaP) that includes diphtheria in their first year. Because diphtheria still prevails in underdeveloped countries, the vaccine remains necessary in case of exposure to a carrier visiting from another country.
Immunization against diphtheria, tetanus, and pertussis
Diphtheria, tetanus, and pertussis vaccines prevent these diseases. Most children who receive all of their shots will be protected during childhood. A combination vaccine is given to babies and children and provides protection against all three diseases. There are several types of the vaccine:
- DTaP vaccine:
- Protects against diphtheria, tetanus, and pertussis.
- Is a newer form of the vaccine and is less likely to cause reactions than earlier types given.
The CDC recommends that children need five DTaP shots. The first three shots are given at 2, 4, and 6 months of age. Between 15 and 18 months of age, the fourth shot is given, and a fifth shot is given when a child enters school at 4 to 6 years of age. At regular checkups for 11- or 12-year-olds, a preteen should get a booster dose of another form of this vaccine called Tdap. Always consult your child's doctor for advice.
