1 Typhoid Fever & Diphtheria What are they? Content source: National Center for Immunization and Respiratory Diseases: Division of Bacterial Diseases

2 What is Typhoid Fever?  Typhoid fever is a life-threatening illness caused by the bacterium Salmonella Typhi. In the United States about 400 cases occur each year, and 75% of these are acquired while traveling internationally. Typhoid fever is still common in the developing world, where it affects about 21.5 million persons each year.

3 How is it spread?  Persons with typhoid fever carry the bacteria in their bloodstream and intestinal tract. A small number of persons, called carriers, recover from typhoid fever but continue to carry the bacteria. Both ill persons and carriers shed S. Typhi in their feces (stool).

4 How is it spread?  You can get typhoid fever if you eat food or drink beverages that have been handled by a person who is shedding S. Typhi or if sewage contaminated with S. Typhi bacteria gets into the water you use for drinking or washing food.  Typhoid fever is more common in areas of the world where handwashing is less frequent and water is likely to be contaminated with sewage.

5 Symptoms  Sustained fever as high as 103° to 104° F (39° to 40° C).  Feel weak, or have stomach pains, headache, or loss of appetite.  May have a rash of flat, rose-colored spots.

6 Treatment: Antibiotics  Persons given antibiotics usually begin to feel better within 2 to 3 days, and deaths rarely occur. However, persons who do not get treatment may continue to have fever for weeks or months, and as many as 20% may die from complications of the infection.

7 Diphtheria  The bacteria most commonly infects the nose and throat. The throat infection causes a gray to black, tough, fiber-like covering, which can block the airways. In some cases, diphtheria may first infect the skin, producing skin lesions.  Antitoxin only in U.S.  Diphtheria remains in developing countries. The countries of the former Soviet Union have reported >150,000 cases in an epidemic which began in 1990. Source for slides to follow: University of Washington School of Medicine

8 How does it spread?  Direct person-to-person transmission (respiratory and physical contact) and through contaminated food and objects.  Because of widespread and routine childhood DPT immunizations, diphtheria is now rare in many parts of the world. There are fewer than five cases of diphtheria a year in the United States.  Risk factors for developing nations: crowded environments, poor hygiene, and lack of immunization.

9 Symptoms  Bluish coloration of the skin  Bloody, watery drainage from nose  Breathing problems  Difficulty breathing  No breathing  Rapid breathing  Stridor, high-pitched breathing sound caused by blockage  Chills  Croup-like (barking) cough  Drooling (airway blockage)  Fever  Hoarseness  Painful swallowing  Skin lesions (usually seen in tropical areas)  Sore throat (may range from mild to severe) TREATMENT: antitoxin and antibiotics Basically, it ends in suffocation …
