Shigellosis, also known as bacillary dysentery, is an infectious disease caused by a group of bacteria called Shigella. This article aims to provide simple and accessible information about Shigellosis, covering various aspects, including its types, causes, symptoms, diagnostic tests, treatments, and commonly prescribed drugs.
Types of Shigellosis:
- Shigella sonnei: This is the most common type in the United States, causing mild to moderate symptoms.
- Shigella flexneri: Common worldwide and responsible for severe symptoms.
- Shigella boydii: Less common but can cause a range of symptoms.
- Shigella dysenteriae: This type is known for its severe and potentially life-threatening effects.
Causes of Shigellosis:
- Bacterial Infection: Shigellosis is caused by Shigella bacteria. It spreads through contact with contaminated food, water, or surfaces.
- Poor Hygiene: Lack of proper handwashing after using the toilet can contribute to its spread.
- Fecal-Oral Route: Ingesting even tiny amounts of infected feces can result in infection.
- Close Contact: Person-to-person transmission, especially in crowded settings, is a common cause.
- Contaminated Food and Water: Consuming food or water contaminated with Shigella can lead to infection.
- Uncooked Food: Raw or undercooked food items, especially seafood, can harbor the bacteria.
- Travel to High-Risk Areas: Traveling to regions with poor sanitation increases the risk.
- Daycare Centers: Children in daycare facilities are more susceptible to infection.
- Anal-Oral Contact: Engaging in sexual practices involving the anal-oral route can transmit the bacteria.
- Exposure to Infected Individuals: Being in close proximity to an infected person can lead to infection.
- Contaminated Objects: Handling objects contaminated with Shigella can transmit the bacteria.
- Immunocompromised Individuals: People with weakened immune systems are more vulnerable.
- Unsanitary Facilities: Using restrooms with poor hygiene standards can contribute to infection.
- HIV Infection: Having HIV may increase the risk and severity of Shigellosis.
- Aging Population: Elderly individuals may be at higher risk due to weakened immunity.
- Contaminated Surfaces: Surfaces in public areas, like doorknobs, can carry the bacteria.
- Contact with Infected Animals: Rarely, contact with infected animals may lead to transmission.
- Lack of Safe Water Sources: Communities without access to clean water are at risk.
- Swimming in Contaminated Pools: Pools with poor hygiene can harbor Shigella.
- Contaminated Medical Equipment: Improperly sanitized medical instruments can transmit the bacteria.
Symptoms of Shigellosis:
- Diarrhea: Frequent, watery, and often bloody stools.
- Abdominal Cramps: Pain and discomfort in the stomach area.
- Fever: Elevated body temperature, usually accompanied by chills.
- Nausea: Feeling like you might vomit.
- Vomiting: Expelling the contents of the stomach.
- Dehydration: Loss of fluids and electrolytes from diarrhea and vomiting.
- Tenesmus: The constant feeling of needing to pass stool.
- Mucus in Stool: A slimy substance may be present in the feces.
- Fatigue: A sense of extreme tiredness.
- Loss of Appetite: Reduced desire to eat.
- Weight Loss: Can result from extended illness.
- Rectal Pain: Discomfort in the rectal area, especially during bowel movements.
- Frequent Urges: An urgent need to use the restroom.
- Joint Pain: Joint discomfort, occasionally associated with infection.
- Headache: Aching in the head.
- Irritability: Feeling easily agitated.
- Bloody Stool: Blood may be visible in the feces.
- Muscle Pain: Sore muscles.
- Malaise: General sense of unwellness.
- High White Blood Cell Count: An indication of the body’s immune response to the infection.
Diagnostic Tests for Shigellosis:
- Stool Culture: A sample of your stool is tested for the presence of Shigella bacteria.
- PCR Test: Detects the genetic material of Shigella to confirm the infection.
- Blood Test: To check for infection-related changes in blood cells.
- Microscopy: Stool samples are examined under a microscope for bacterial identification.
- Rectal Swab: A swab from the rectum can help identify the bacteria.
- Serology Test: Measures antibody levels in your blood to diagnose recent or past infection.
- Imaging Tests: In severe cases, imaging like X-rays may be done to rule out complications.
- Medical History: Your doctor will ask about your symptoms and recent activities.
- Physical Examination: Your healthcare provider will check for signs of Shigellosis.
- Travel History: If you’ve traveled, this information can be crucial in diagnosis.
- Checking for Dehydration: Healthcare professionals assess your hydration status.
- Checking for Blood in Stool: A simple test to identify blood in your stool.
- Assessing Abdominal Tenderness: To determine the severity of symptoms.
- Assessing Fever: Monitoring body temperature.
- Testing for Electrolyte Imbalance: Especially in cases of severe diarrhea.
- Checking for Complications: In severe cases, more extensive testing may be needed.
- Testing for Other Infections: To rule out other possible causes of symptoms.
- Assessing Nutritional Status: Especially important for children and the elderly.
- Drug Allergy Testing: If antibiotics are prescribed, your doctor may check for allergies.
- Repeating Tests: Sometimes, multiple tests are needed to confirm the diagnosis.
Treatments for Shigellosis:
- Hydration: Drinking fluids, including oral rehydration solutions, to combat dehydration.
- Rest: Getting plenty of rest to help your body recover.
- Antibiotics: In severe cases or for vulnerable individuals, antibiotics may be prescribed.
- Probiotics: Beneficial bacteria supplements to restore gut health.
- Pain Relief: Over-the-counter pain relievers for discomfort.
- Avoiding Certain Medications: Some anti-diarrheal medications may make the infection worse.
- Dietary Changes: Following a bland diet, avoiding spicy or fatty foods.
- Isolation: To prevent the spread of the infection to others.
- Quarantine: If advised by healthcare authorities during outbreaks.
- Handwashing: Frequent and thorough handwashing to prevent further spread.

- Monitoring: Regularly checking your symptoms and seeking medical attention if they worsen.
- Antibiotic Resistance: Taking antibiotics exactly as prescribed to prevent resistance.
- Preventing Re-infection: Taking steps to avoid future exposure.
- Childcare Measures: Ensuring good hygiene in daycare settings.
- Safe Food Handling: Following food safety guidelines.
- Clean Water: Using clean water sources for drinking and cooking.
- Safe Sexual Practices: Reducing the risk of transmission through anal-oral contact.
- Travel Precautions: Taking precautions when traveling to high-risk areas.
- Health Education: Raising awareness about Shigellosis prevention in communities.
Commonly Prescribed Drugs for Shigellosis:
