Viral Gastroenteritis

Viral Gastroenteritis

Gastroenteritis, when caused by viruses, is common in adults and children. Particularly in individuals with a compromised immune system, the infection is prevalent. Most cases of gastroenteritis are caused by viruses, with significant morbidity for young and elderly patients. 

Sometimes also known as stomach flu, the condition bears no similarity to influenza except that a virus causes it. 

The United States records the most number of cases of viral gastroenteritis, with nearly 200,000 childhood deaths recorded globally. Various viruses can cause the symptoms. However, the causative agent is not easily detected. The different viruses that may cause the infection are- Rotavirus, Norovirus, astrovirus, and adenovirus. 

The virus is transmitted through the fecal-oral route, which can be through contamination of water or food. The virus is also transmitted through vomitus, fomites, and airborne methods.

When Norovirus causes the infection, the symptoms are detected to be as follows: 

  • Malaise, 
  • myalgias, 
  • Low-grade fever (~ 39 degrees C)
  • Non-bloody diarrhea
  • Multiple bowel movements
  • Severe and prolonged illness is observed in patients with a weakened immune system
  • Abdominal pain 
  • Fever
  • Vomiting
  • Nausea

The acute signs of the illness can last up to one to three days. When the symptoms are persistent for more than two weeks, they are classified as chronic. Mild abdominal pain and mild fever are joint. 


Patients who are well-hydrated and lack risk factors are not tested as they are not at any risk of complications. 

The diagnosis of gastroenteritis is through a complete blood count that reveals a mild leukocytosis. This test aids in ruling out other causes of the symptoms.

Another indicator of this condition is hemoconcentration on comprehensive blood count testing and electrolyte disturbance. The other serum markers may also appear elevated. 


The treatment of this infection is focused on hydrating the patient and controlling the electrolyte and fluid loss. The treatment goal is to reduce the discomfort from the symptoms through medications such as antiemetics, which manage the vomiting and nausea symptoms.

In addition, patients who experience continuous vomiting must be admitted to the hospital for administering intravenous fluid and constant monitoring. The rehydration is fulfilled through lactated Ringer’s solution and saline. 

However, medication for elderly patients is not encouraged as it may lead to complications due to drug-drug interaction. 

What is this? 

Are viral and bacterial gastroenteritis similar to hemorrhagic gastroenteritis? The latter is reported in dogs and can be fatal. The symptoms are mainly noted as bloody diarrhea and vomiting, which may be fatal. 


The prevention of this infection is similar to any other food-borne illness caused by the virus. Hand-washing and disinfecting contaminated surfaces are the best ways to reduce the chances of catching the condition. The additional preventative steps include avoiding food and water that may be contaminated. 

Disinfecting the contaminated clothes and articles through washing and disinfection.

The treatment includes antibiotics that can cure the condition within a few days. However, the additional treatment includes replenishing the fluids and electrolytes the patient may have lost due to vomiting and diarrhea.

The treatment can also include IV fluid replacement if the condition is severe. The main aim of hydrating the patient is to ensure no complications. It is essential to maintain the nutrients, specifically potassium and sodium. 


The preventative steps include safety precautions that prevent the transmission of bacteria to healthy individuals. These are: 

  1. Washing hands after the use of the toilet and handling food
  2. Avoiding public gatherings to prevent transmission
  3. Avoiding close contact with healthy individuals
  4. WHO recommends waiting 48 hours before returning to work 
  5. Do not store food at room temperature (very high or low temperatures) for more than a few hours.
