Shigella infection has recently gained attention because of increasing reports from different parts of Kerala. The infection spreads very easily from one person to another and can affect both children and adults.
Simple hygiene measures, safe food handling and clean drinking water can significantly reduce the risk of infection. Understanding how the disease spreads is one of the best ways to protect your family.
What is Shigella infection
Shigella is a group of bacteria that causes an intestinal infection known as shigellosis. The illness mainly affects the digestive system and commonly causes diarrhea, stomach cramps and fever.
The infection spreads easily because only a very small number of bacteria are needed to make a person sick.
How does Shigella spread
Shigella mainly spreads through the fecal oral route. Infection occurs when tiny amounts of contaminated stool reach another person through contaminated hands, food, water or frequently touched surfaces.
Close contact within families, childcare centers, schools and crowded environments increases the chance of transmission.
Contaminated food and drinking water
Food prepared by an infected person without proper hand washing may spread the bacteria to others. Drinking water contaminated with sewage can also become a source of infection.
Raw vegetables, salads, uncooked foods and improperly handled meals may carry the bacteria if hygiene standards are poor.
Common symptoms
Symptoms usually begin one to three days after exposure and commonly include diarrhea, stomach pain, abdominal cramps, fever and a feeling of weakness.
Some individuals may develop bloody diarrhea or frequent loose stools, which require prompt medical attention.
Who is at higher risk
Young children, older adults and individuals with weakened immunity are more likely to develop complications from Shigella infection.
People living in crowded environments or areas with inadequate sanitation may also have a higher risk of infection.
How to protect your family
Wash hands thoroughly with soap and clean water before preparing food, before eating and after using the toilet. Encourage children to develop proper hand hygiene from an early age.
Drink safe water, eat freshly prepared food, wash fruits and vegetables properly and avoid consuming food from unhygienic sources.
Preventing spread at home
An infected individual should avoid preparing food for others until fully recovered. Toilets, bathroom surfaces and commonly touched objects should be cleaned regularly.
Separate towels, frequent hand washing and careful disposal of contaminated materials help reduce household transmission.
Importance of hydration
Diarrhea can lead to dehydration, especially in young children and older adults. Adequate fluid intake is essential during recovery.
Signs such as excessive thirst, dry mouth, reduced urination or unusual drowsiness require prompt medical evaluation.
When should medical advice be sought
Medical evaluation should be sought if diarrhea is severe, contains blood, lasts several days, is associated with persistent vomiting or if signs of dehydration develop.
Infants, elderly individuals, pregnant women and people with chronic medical conditions should receive early medical assessment if symptoms occur.
Creating awareness protects communities
Most Shigella infections can be prevented through good hygiene, safe drinking water and proper food handling practices.
Community awareness, personal cleanliness and timely medical care remain the most effective ways to reduce the spread of this highly contagious infection.
