Overview
Salmonella infection, also known as salmonellosis, is a common bacterial disease that affects the intestinal tract. Salmonella bacteria typically live in animal and human intestines and are shed through stool (feces). Humans become infected most frequently through contaminated water or food.
Types of Salmonella infection
There are several types of Salmonella infections, including:
- Typhoid fever: A severe form of Salmonella infection that can cause fever, headache, and fatigue.
- Paratyphoid fever: A milder form of Salmonella infection that can cause fever, headache, and fatigue.
- Non-typhoidal Salmonella infection: A mild to moderate form of Salmonella infection that can cause diarrhea, fever, and abdominal cramps.
Causes of Salmonella infection
Salmonella bacteria typically live in animal and human intestines and are shed through stool (feces). Humans become infected most frequently through contaminated water or food. Contaminated water or food can be:
- Unpasteurized milk or dairy products: Unpasteurized milk or dairy products can contain Salmonella bacteria.
- Undercooked or raw meat: Undercooked or raw meat can contain Salmonella bacteria.
- Contaminated produce: Fresh produce can be contaminated with Salmonella bacteria.
- Fecally contaminated food: Food that has been contaminated with feces can contain Salmonella bacteria.
Risk Factors of Salmonella infection
The risk of getting Salmonella infection is higher with:
- Travel to countries without clean drinking water and proper sewage disposal: Travel to countries without clean drinking water and proper sewage disposal can increase the risk of getting Salmonella infection.
- Pregnancy: Pregnant women are more likely to develop severe symptoms of Salmonella infection.
- Older age: Older adults are more likely to develop severe symptoms of Salmonella infection.
- Weakened immune system: People with a weakened immune system, such as those with HIV/AIDS or taking immunosuppressive medications, are more likely to develop severe symptoms of Salmonella infection.
Symptoms of Salmonella infection
Most people with Salmonella infection develop symptoms within 8 to 72 hours after exposure. Symptoms can include:Preventions of Salmonella infection
Preventing Salmonella infection is important to reduce the risk of developing this condition. Prevention strategies include:
- Washing hands: Washing hands regularly with soap and water is important to prevent the spread of Salmonella infection.
- Cooking food: Cooking food thoroughly can kill Salmonella bacteria.
- Avoiding raw or undercooked eggs: Avoiding raw or undercooked eggs can reduce the risk of getting Salmonella infection.
- Avoiding unpasteurized milk or dairy products: Avoiding unpasteurized milk or dairy products can reduce the risk of getting Salmonella infection.
Diagnosis of Salmonella infection
Diagnosing Salmonella infection typically involves a combination of:
- Medical history: Taking a medical history to determine the symptoms and duration of illness.
- Physical examination: Performing a physical examination to assess for signs of illness such as fever, diarrhea, and abdominal cramps.
- Laboratory tests: Performing laboratory tests such as stool cultures to detect the presence of Salmonella bacteria.
Treatment for Salmonella infection
Treatment for Salmonella infection typically involves:
- Rest and hydration: Rest and hydration are important to help manage symptoms such as diarrhea and abdominal cramps.
- Antibiotics: Antibiotics may be prescribed in severe cases of Salmonella infection to prevent complications such as life-threatening sepsis.
When to seek medical attention ?
If you experience symptoms of Salmonella infection such as diarrhea, fever, and abdominal cramps, it is important to seek medical attention. Your doctor may recommend antibiotics if you have a severe case of Salmonella infection.
