Viral gastroenteritis

Overview

Viral gastroenteritis is an intestinal infection that affects millions of people worldwide. It is commonly referred to as the "stomach flu" due to its similarity to the symptoms of influenza. However, it is not caused by the flu virus and is instead caused by a variety of viruses that infect the stomach and intestines. The symptoms of viral gastroenteritis typically include watery diarrhea, stomach cramps, nausea or vomiting, and sometimes fever.

Types of Viral gastroenteritis

1. Norovirus: Norovirus is a highly contagious virus that causes most cases of viral gastroenteritis. It is spread through contaminated food, water, and close contact with an infected person.
2. Rotavirus: Rotavirus is a virus that primarily affects young children and is a common cause of viral gastroenteritis in this age group.
3. Adenovirus: Adenovirus is a group of viruses that can cause viral gastroenteritis in people of all ages.

Causes of Viral gastroenteritis

1. Contaminated food or water: Consuming food or water that has been contaminated with a virus can cause viral gastroenteritis.
2. Close contact with an infected person: Being in close contact with someone who has viral gastroenteritis can spread the infection.
3. Touching contaminated surfaces: Touching surfaces or objects that have been contaminated with the virus can also spread the infection.

Risk Factors of Viral gastroenteritis

1. Age: Young children and older adults are more susceptible to developing severe symptoms of viral gastroenteritis.
2. Weakened immune system: People with weakened immune systems, such as those with HIV/AIDS or undergoing chemotherapy, are more susceptible to developing severe symptoms of viral gastroenteritis.
3. Travel: Traveling to areas where there are outbreaks of viral gastroenteritis can increase the risk of developing the infection.
