How do bacteria or viruses make people sick?

i think your talking about Gastroenteritis

its also known as stomach flu or tummy bug gastroenteritis is caused by a wide variety of bacteria and viruses.

Gastroenteritis has many causes. Viruses and bacteria are the most common.

The infectious agents can come from outside your body or internally from some abnormal condition. For example, both normal and disease-causing intestinal bacteria may grow when antacids or other medication alter the stomach acidity.

Viruses and bacteria are very contagious and can spread through contaminated food or water. In up to 50% of diarrheal outbreaks, no specific agent is found. Improper handwashing following a bowel movement or handling a diaper can spread the disease from person to person.

Gastroenteritis caused by viruses may last 1-2 days. On the other hand, bacterial cases can last a week or more.
