Pharyngeal (throat) diphtheria is a contagious and potentially life-threatening infection caused by a bacteria (Corynebacterium diphtheriae) that produces a toxin (poison). A greyish membrane forms that can block the throat and airways and sometimes the toxin can result in damage to the heart and nerves.
How is pharyngeal diphtheria spread?
Diphtheria spreads from person to person, usually through respiratory droplets, like from coughing or sneezing. It can also spread by touching open sores or ulcers of someone with a diphtheria skin infection.
What are the two types of diphtheria?
Diphtheria is a highly contagious and potentially life-threatening bacterial disease caused by Corynebacterium diphtheriae. There are two types of diphtheria: respiratory and cutaneous. Respiratory diphtheria involves the nose, throat and tonsils, and cutaneous diphtheria involves the skin.
What type of precaution is pharyngeal diphtheria?
1. Hospitalized patients with confirmed pharyngeal diphtheria should be cared for using droplet precautions until they have completed antimicrobial therapy and two cultures taken at least 24 hours apart, and at least 24 hours after cessation of antimicrobial therapy, fail to show diphtheria organisms.What is the root cause of diphtheria?
What causes diphtheria? Diphtheria is caused by bacteria adhering to the lining of the respiratory system. These bacteria generate a toxin which damages tissue cells of the respiratory system.
How long can diphtheria live outside the body?
SURVIVAL OUTSIDE HOST: C. diphtheriae can survive on dry inanimate surfaces from 7 days to 6 months 16.
How long does diphtheria last for?
How long does diphtheria last? Usually the matter is settled, one way or the other, in 7 to 10 days. Sometimes there are lasting complications such as arthritis, paralysis, or brain damage.
Does diphtheria require droplet precautions?
Patient isolation: standard + droplets for patients and carriers with pharyngeal diphtheria; contact for cutaneous diphtheria. The isolation should be continued until 2 cultures taken 24 hours after completing antimicrobial treatment are negative.Is pharyngeal diphtheria a droplet?
Diphtheria bacteria spread from person to person, usually through respiratory droplets, like from coughing or sneezing. People can also get sick from touching infected open sores or ulcers.
Does diphtheria infection of the throat require droplet precautions?2. Apply standard precautions, including hand hygiene at all times. 3. In addition, also apply droplet and contact precautions.
Article first time published onWhat are the 5 types of diphtheria?
- classical respiratory diphtheria.
- laryngeal diphtheria.
- nasal diphtheria and.
- cutaneous diphtheria (skin lesions).
Why is the back of my throat GREY?
Within two to three days, the dead tissue forms a thick, gray coating that can build up in the throat or nose. Medical experts call this thick, gray coating a “pseudomembrane.” It can cover tissues in the nose, tonsils, voice box, and throat, making it very hard to breathe and swallow.
Where is diphtheria most common?
Diphtheria rarely occurs in the United States and Western Europe, where children have been vaccinated against the condition for decades. However, diphtheria is still common in developing countries where vaccination rates are low.
Does cat hair cause diphtheria?
The latest edition of Emerging Infectious Diseases (Berger et al 2011) describes a case of Corynebacterium ulcerans infection in a women that was likely acquired from her cat. Corynebacterium ulcerans is a bacterium that’s related to C. diphtheriae, the cause of diphtheria.
What antibiotics treat diphtheria?
Antibiotics. The recommended antibiotics for respiratory or cutaneous diphtheria is either erythromycin or penicillin.
What diphtheria smells like?
Infectious diseases were known by their characteristics odors–scrofula as smelling like stale beer; typhoid, like freshly baked brown bread; rubella, like plucked feathers; and diphtheria, as “sweetish.” Anosmics might be banned from medical school.
Who does diphtheria affect most?
Diphtheria is a bacterial infection. It spreads easily and happens quickly, and mainly affects the nose and throat. Children under 5 and adults over 60 years old are particularly at risk for getting it.
Can you get diphtheria more than once?
Once you recover from diphtheria, you’ll need a full course of diphtheria vaccine to prevent a recurrence. Unlike some other infections, having diphtheria doesn’t guarantee lifetime immunity. You can get diphtheria more than once if you’re not fully immunized against it.
How was diphtheria eradicated?
Implementation of childhood vaccination virtually eliminated diphtheria from developed countries after the Second World War and implementation of the Expanded Program on Immunization in developing countries led to rapid declines in diphtheria globally in the 1980s.
What is the portal of exit for diphtheria?
In most cases the bacillus is transmitted in droplets of respiratory secretions expelled by active cases or carriers during speaking or coughing. The most common portals of entry of the diphtheria bacillus are the tonsils, nose, and throat.
Is diphtheria a DNA or RNA virus?

What type of toxin causes tetanus symptoms?
Tetanus is an acute, sometimes fatal, disease of the central nervous system, caused by the toxin of the bacterium clostridium tetani. The bacterium clostridium tetani usually enters the body through an open wound.
Is tetanus a virus?
Tetanus is an infection caused by bacteria called Clostridium tetani. When the bacteria invade the body, they produce a poison (toxin) that causes painful muscle contractions. Another name for tetanus is “lockjaw”.
Is measles an airborne disease?
Measles is one of the most contagious of all infectious diseases; up to 9 out of 10 susceptible persons with close contact to a measles patient will develop measles. The virus is transmitted by direct contact with infectious droplets or by airborne spread when an infected person breathes, coughs, or sneezes.
What is droplet transmission?
Droplet transmission occurs when bacteria or viruses travel on relatively large respiratory droplets that people sneeze, cough, or exhale. They travel only short distances (usually less than 2 meters) before settling.
What is droplet precaution?
Droplet Precautions are used to prevent the spread of pathogens that are passed through respiratory secretions and do not survive for long in transit. These droplets are relatively large particles that cannot travel though the air very far. They are transmitted through coughing, sneezing, and talking.
What PPE should be worn for droplet precautions?
If you are treating a patient in droplet precautions you need to wear a mask, gown and gloves.
What should be done if a patient is an asymptomatic carrier of diphtheria?
Postexposure antibiotics diphtheriae. Asymptomatic contacts should be treated with erythromycin 500 mg (10 to 15 mg/kg for children) orally every 6 hours for 7 days or, if adherence is uncertain, a single dose of penicillin G benzathine (600,000 units IM for patients < 30 kg and 1.2 million units IM for those > 30 kg).
Is diphtheria the same as whooping cough?
Whooping cough (pertussis), tetanus, and diphtheria are serious diseases caused by bacteria. Whooping cough and diphtheria are spread person-to-person through the air. Tetanus gets into the body through cuts or wounds.
When was the last case of diphtheria in the United States?
In the 1920s, there were between 100,000 and 200,000 cases of diphtheria each year with 13,000–15,000 deaths. Because of widespread immu- nization and better living conditions, diphtheria is now rare in the United States (during 2004–2017, state health departments reported 2 cases of diphtheria in the United States).
Can dogs get diphtheria?
It is well known that diphtheria may be transmitted by domestic animals by way of fur, particularly by animals coming in close contact with people during attacks of diphtheria. Having traced the source of infection to the throat of a dog, I am prompted to report the following cases: Case 1.
