Reduce your risk by following these habits:
Wash Your Hands
Wash with soap and water:
- Before eating
- Before preparing food
- After using the bathroom
- After changing diapers
- After handling animals
Drink Safe Water
Drink treated or bottled water when water quality is uncertain.
Avoid swallowing water while swimming in pools, lakes, or rivers.
Practice Food Safety
- Wash fruits and vegetables thoroughly.
- Cook meat completely.
- Refrigerate perishable foods promptly.
- Avoid cross-contamination between raw and cooked foods.
When Should You See a Doctor?
Contact a healthcare provider if you experience:
- Diarrhea lasting more than three days
- Bloody stools
- Severe abdominal pain
- Persistent vomiting
- High fever
- Signs of dehydration
- Symptoms after international travel
- Symptoms in infants, older adults, or people with weakened immune systems
A stool test may be needed to determine whether a parasite, bacteria, or virus is causing the illness.
Treatment
Treatment depends on the cause.
Some parasitic infections require prescription antiparasitic medications, while others improve with supportive care and hydration.
Avoid taking antibiotics unless prescribed, as they are not effective against most parasites and are unnecessary for many viral causes of diarrhea.
Final Thoughts
Diarrheal illnesses can become more serious during periods of extreme heat because the body loses fluids through both sweating and gastrointestinal symptoms. Staying hydrated, practicing good hand hygiene, preparing food safely, and drinking clean water are the best ways to reduce your risk.
If you develop severe diarrhea, persistent vomiting, bloody stools, or signs of dehydration, seek medical care promptly. Early treatment and proper hydration can help prevent complications and speed recovery.
