Acute diarrhea in children refers to the sudden onset of three or more loose or watery stools in a 24-hour period, lasting for less than two weeks. It is one of the most common health issues affecting infants and young children around the world. The condition can be caused by a variety of factors, most commonly infections from viruses (such as rotavirus or norovirus), bacteria (like E. coli or Salmonella), or parasites (such as Giardia).
While acute diarrhea is usually self-limiting and resolves on its own, it can become serious if not properly managed, especially in young children who are more vulnerable to rapid fluid loss. Dehydration is the most concerning complication and can develop quickly, leading to serious health risks if not treated promptly. Common signs of dehydration include dry mouth, sunken eyes, decreased urination, and lethargy.
Other symptoms that may accompany diarrhea include fever, vomiting, abdominal cramps, irritability, and loss of appetite. In most cases, treatment focuses on preventing dehydration through increased fluid intake, often using oral rehydration solutions (ORS). However, in more severe cases, medical evaluation and intervention may be necessary.
Parents and caregivers are advised to monitor the child's condition closely and seek medical advice if symptoms persist, worsen, or are accompanied by alarming signs such as blood in the stool, high fever, or signs of severe dehydration.
The Guarino Score is a clinical assessment tool designed to help healthcare providers evaluate the severity of acute diarrhea in children. Developed by pediatric experts, it provides a structured way to assess visible symptoms that indicate the child’s level of dehydration or general condition. This scoring system is particularly useful in both clinical settings and at-home evaluations by trained caregivers.
The Guarino Score is calculated by observing four main physical indicators:
Each of these indicators is scored from 0 (normal) to 2 (severe), and the total score can range from 0 to 8. The higher the score, the more severe the condition. For example, a score of 0–2 may suggest mild or no dehydration, 3–5 indicates moderate dehydration, and 6–8 points to severe dehydration requiring immediate medical attention.
This scoring system allows for quick, systematic decision-making when determining the appropriate level of care—whether the child can be treated at home with fluids and rest or if professional medical treatment is necessary.
The Guarino Score Calculator is designed to help assess the severity of acute diarrhea in children by evaluating key physical symptoms. Its main purpose is to provide a simple, quick, and structured way for healthcare providers and caregivers to determine whether a child may be experiencing mild, moderate, or severe dehydration due to diarrhea.
By guiding users through a series of observations—such as the child’s appearance, eye condition, tongue moisture, and tear production—the calculator generates a total score that reflects the child's current health status. This information can support timely decision-making and prompt appropriate treatment or referral to medical care when needed.
This calculator is a valuable tool for quickly identifying the level of dehydration in children suffering from acute diarrhea. Since dehydration can progress rapidly, especially in infants and young children, early detection is critical. The calculator offers an evidence-based method to evaluate symptoms and respond appropriately.

The Guarino Score Calculator is intended for use by:
While the calculator can be helpful for non-professionals, it is important to understand that it does not replace professional medical advice. If a child shows signs of severe dehydration or other concerning symptoms, immediate consultation with a healthcare provider is strongly recommended.
The Guarino Score Calculator is based on a simple point system that evaluates four key physical signs observed in children with acute diarrhea. Each sign is scored from 0 to 2 depending on its severity. The scores are then added together to give a total score that indicates the degree of dehydration or clinical severity.
The calculator is interactive and easy to use. You simply select the option that best describes the child's condition under each category—General Appearance, Eyes, Tongue, and Tears. As you select the answers, the calculator automatically totals the points and displays the score. This score helps determine the appropriate level of care and whether medical attention is needed.
The Guarino Score is composed of four clinical observations. Each observation is assigned a score from 0 to 2:
The final score ranges from 0 to 8. A higher score indicates greater concern and a potential need for medical evaluation or intervention.
This category assesses the child’s overall behavior and responsiveness. It helps detect changes in alertness and physical activity.
This category looks at the appearance of the eyes, which can reflect fluid loss.
The moisture of the tongue is an easy way to detect hydration status.
This evaluates tear production when the child cries, which is another sign of hydration.
The Guarino Score Calculator is designed to be easy to use, even for non-medical users. Follow the steps below to assess the severity of diarrhea in a child and determine whether medical care is needed.
The calculator will automatically add the selected scores from each category and display a total score from 0 to 8. This number gives you a quick overview of the child’s condition and can guide your next steps.
After using the calculator, it’s important to know what the total score means. The higher the score, the more likely the child is experiencing moderate to severe dehydration and may need medical care.
Regardless of the score, there are certain symptoms that should prompt immediate medical attention. These signs may indicate a more serious condition that requires professional intervention.
The Guarino Score, also known as the Vesikari Score, is a clinical tool used to assess the severity of acute diarrhea in children based on symptoms such as stool consistency, vomiting, fever, and dehydration signs.
Each symptom is assigned a score, and the total score helps determine the severity of the condition. Higher scores indicate more severe acute diarrhea.
If a child has persistent diarrhea lasting more than a few days, severe dehydration signs (such as no tears, sunken eyes, lethargy), or an inability to keep fluids down, medical attention is required.
Acute diarrhea in children is often caused by viral, bacterial, or parasitic infections, contaminated food or water, or as a reaction to medications.
Management focuses on preventing dehydration using oral rehydration solutions (ORS) or intravenous fluids when necessary. Supportive care, dietary modifications, and in some cases, antimicrobial therapy, may be required.
