Salmonellosis Basics

Salmonellosis is illness caused by the bacterium Salmonella. It is one of the more common causes of gastroenteritis with more than 2300 cases occurring in Georgia each year. Most cases occur in the summer and early fall months and are seen as single cases, clusters, or outbreaks. Salmonellosis symptoms typically include diarrhea (sometimes with bloody stool), fever, nausea, abdominal pain, or vomiting. Most persons with Salmonella infection do not require medical treatment, and symptoms often resolve without medication. The elderly, infants, and those with impaired immune systems are more likely to have a severe illness

Salmonella is spread by ingestion of Salmonella bacteria in food derived from infected animals or food contaminated by feces of an infected animal or person. Common vehicles include undercooked eggs, raw milk, contaminated water, meat and poultry. Pet turtles, iguanas and chicks are common sources for infants and children. Fecal-oral transmission from person to person is important, especially when diarrhea is present. Most people infected with Salmonella develop symptoms between 12 and 72 hours after infection; the illness usually lasts 4 to 7 days.

The best way to prevent Salmonella infection is by practicing good hand hygiene. Wash your hands with soap and water before eating or preparing food, after changing diapers, and after using the restroom. Avoid swallowing water from ponds, lakes, or recreational water that is untreated.

Typhoid fever/Paratyphoid fever Basics

Typhoid fever and paratyphoid fever are life-threatening bacterial illnesses caused by Salmonella serotype Typhi and Salmonella serotype Paratyphi, respectively. Both have similar symptoms including sustained fever, weakness, stomach pain, diarrhea, and loss of appetite. These illnesses are uncommon in Georgia, with around 20 total cases each year.

Most people in the United States with typhoid fever or paratyphoid fever become infected while traveling abroad, most often to countries where these diseases are common. If you plan to travel outside of the United States, find out if you need the typhoid fever vaccine at www.cdc.gov/travel.

Typhoid fever and paratyphoid fever are treated with antibiotics. People who do not get appropriate antibiotic treatment may have fever for weeks or months and may develop complications. People who do not get treatment can die from complications of the infection.

Even if your symptoms seem to go away, you may still be carrying Salmonella typhi or Salmonella paratyphi. If so, the illness could return, or you could pass the bacteria to other people. In fact, if you are a healthcare worker or work at a job where you handle food or care for small children, you may not be able to return to work until a doctor has determined you no longer carry the bacteria.

If you are being treated for typhoid fever or paratyphoid fever, it is important to do the following to lower the chance that you will pass the bacteria on to someone else.

• Keep taking antibiotics for as long as the doctor has recommended.
• Wash your hands carefully with soap and water after using the bathroom.
• Do not prepare or serve food for other people.

Typhoid fever/Paratyphoid fever Information for Healthcare Professionals

Diagnosis and Treatment

Blood culture is the mainstay of diagnosis. Bone marrow cultures have sensitivity of 80% in some studies and can remain positive despite antibiotic therapy. Stool and urine cultures are positive less frequently. Multiple cultures are usually needed to identify the pathogen. Serologic tests, such as the Widal test, are not recommended because of the high rate of false positives.
