Hello,
I have gone through your query and understand your concern.
All the family members are AGE ( Acute
Gastroenteritis).
Thus is most commonly due to infection by virus, bacteria or parasites in spoiled food or uncleaned water.
Viruses and bacteria are very contagious and can spread through contaminated food or water.
Improper hand washing following a bowel movement or handling a diaper can spread the disease from person to person.
In Acute gastroenteritis, avoiding
dehydration and electrolyte loss is prime importance.
Because fluid and electrolyte loss beyond some level may result in life threatening illness.
If the infection is persistent or come back again, it is essential to identify the causative organism.
This may require blood work up, stool examination and culture,
blood culture , serum electrolytes etc.
It is not advisable to take
loperamide in acute infection.
Drink plenty of water and non caffinated non dairy drinks.
For
vomiting you can take medications like
promethazine or perchlorperazine suppositories.
Please follow this basic hygenic measures to avoid further infection in future.
1. Always wash your hands before eating and after using toilet.
2. Eat properly prepared and stored food.
3. Bleach soiled laundry cleanly.
4. Check the water if they are stored.
5. Clean the water storage tank regularly
Hope this helps.
Please write back for further queries.
Wishing you good health.
