In the healthcare field, protecting both patients and healthcare workers from infections is very important. To achieve this, guidelines and safety measures are followed across hospitals, clinics, and other care settings. Two such safety practices are universal precautions and standard precautions. While they may sound similar, they are not exactly the same. Many people often wonder, how are standard precautions different than universal precautions? Understanding the difference helps healthcare professionals apply the right measures when caring for patients.
This blog will explain both types of precautions in a very simple and formal way. We will look at their meaning, history, key components, and differences, so that even those new to the healthcare field can easily understand and follow them.
What Are Universal Precautions?
Universal precautions were introduced in the 1980s, especially during the early years of the HIV/AIDS epidemic. At that time, there was a high concern about the risk of infection from blood and bodily fluids.
The Centers for Disease Control and Prevention (CDC) recommended universal precautions to reduce the risk of transmission of bloodborne diseases such as:
- HIV
- Hepatitis B (HBV)
- Hepatitis C (HCV)
Key idea of universal precautions:
Treat all blood and certain body fluids from all patients as if they are infectious, regardless of the patient’s medical history.

What Do Universal Precautions Include?
Universal precautions mainly focus on avoiding contact with blood and bodily fluids that may contain blood. The main safety measures under universal precautions are:
- Wearing gloves when touching blood, body fluids, or contaminated items
- Wearing gowns, masks, and protective eyewear if splashes of blood or fluids are likely
- Using safe needle handling and disposal methods
- Washing hands before and after contact with any patient or potentially contaminated surface
Universal precautions are applied only when there is a risk of blood exposure.
What Are Standard Precautions?
Standard precautions were introduced later in the 1990s and are considered an improved version of universal precautions. They combine the principles of universal precautions with other important infection control practices.
The idea behind standard precautions is to assume that every person may be infected or carry germs, not just those with visible blood or body fluids. Therefore, standard precautions are applied to all patients at all times, not just those who seem ill or injured.
Key idea of standard precautions:
Apply safety measures to protect against all body fluids, including blood, secretions, excretions (except sweat), non-intact skin, and mucous membranes.
What Do Standard Precautions Include?
Standard precautions are broader and more detailed than universal precautions. They include:
- Hand Hygiene
- Washing hands with soap and water or using alcohol-based hand rub
- Before and after patient contact
- After removing gloves
- Use of Personal Protective Equipment (PPE)
- Gloves, masks, gowns, and eye protection
- Based on the type of care and expected exposure
- Respiratory Hygiene and Cough Etiquette
- Covering mouth and nose when coughing or sneezing
- Using tissues and disposing of them properly
- Wearing masks when needed
- Safe Injection Practices
- Using a new needle and syringe for every injection
- Disposing of sharps in proper containers
- Safe Handling of Equipment
- Cleaning and disinfecting tools and machines after use
- Avoiding reuse of single-use items
- Environmental Cleaning
- Regular cleaning of patient areas and medical surfaces
- Proper waste disposal
- Handling of Linen and Laundry
- Wearing gloves when handling dirty or contaminated linen
- Storing soiled laundry in leak-proof containers
How Are Standard Precautions Different Than Universal Precautions?
Now that we have looked at both types, let us directly answer how are standard precautions different than universal precautions.
| Point of Difference | Universal Precautions | Standard Precautions |
|---|---|---|
| Scope | Focus only on blood and certain body fluids | Covers all body fluids (except sweat), non-intact skin, and mucous membranes |
| Application | Applied only when there is risk of blood exposure | Applied to all patients at all times |
| Introduction Year | 1980s | 1990s |
| Main Purpose | Prevent spread of bloodborne diseases like HIV and Hepatitis B | Prevent spread of all infections including airborne, droplet, and contact-based infections |
| Includes Hand Hygiene | Not specifically emphasized | Strongly emphasized and detailed |
| Includes Respiratory Hygiene | No | Yes |
| Includes Environmental Cleaning | No | Yes |
| Includes Safe Injection Practices | Basic | Detailed and strict |
| Risk-Based or Universal Application | Based on blood exposure risk | Applied regardless of risk level |
| Broader Coverage | No | Yes – more comprehensive |
Why Were Standard Precautions Introduced?
Universal precautions were helpful but had limitations. They only focused on blood and missed other possible sources of infection like saliva, mucus, urine, or skin infections. As knowledge about infections improved, experts realized that more protection was needed.
So, standard precautions were created to include all possible infection sources, not just blood. This change helped healthcare workers stay safe even in cases where infections were not visible or known.
For example:
- A patient may have a cold, and the virus spreads through droplets.
- Another patient might have diarrhea caused by bacteria in their stool.
- In both cases, standard precautions provide the needed protection.
Importance of Using Standard Precautions in Healthcare
Standard precautions are now the main method of infection prevention in hospitals, clinics, and other healthcare settings. Here’s why they are important:
- Protects healthcare workers from unexpected infections
- Protects patients from getting infections during treatment
- Reduces hospital-acquired infections (HAIs)
- Improves safety in surgeries, injections, and wound care
- Applies to everyone, regardless of age, gender, or illness
When all healthcare staff follow standard precautions, it creates a safer and healthier environment for everyone.
Examples to Understand the Difference Better
Example 1: Drawing Blood from a Patient
- Universal Precautions: Wear gloves, avoid contact with blood
- Standard Precautions: Wear gloves, follow hand hygiene, dispose of needle properly, clean the area, and follow respiratory hygiene if the patient coughs
Example 2: Caring for a Patient with Vomiting
- Universal Precautions: May not require protection if blood is not involved
- Standard Precautions: Use gloves, mask, gown, and disinfect the area after cleaning the vomit
Example 3: Treating a Cut on the Arm
- Universal Precautions: Wear gloves to avoid blood contact
- Standard Precautions: Wear gloves, practice hand hygiene before and after, and clean equipment used during the treatment
Who Should Follow These Precautions?
Standard precautions are followed by:
- Doctors
- Nurses
- Lab technicians
- Housekeeping staff
- Dentists
- Paramedics
- Caregivers in home healthcare
- Anyone who comes into contact with patients or medical equipment
Even visitors may be guided to follow some standard precautions like hand hygiene or wearing masks, especially during disease outbreaks.
Final Notes on Best Practices
Here are some simple rules to remember:
- Always assume every patient may carry an infection
- Always practice hand hygiene before and after patient contact
- Wear PPE based on the task, not just the patient’s diagnosis
- Never reuse needles or syringes
- Always clean and disinfect surfaces and tools
- Safely dispose of sharps and contaminated items
- Keep yourself vaccinated and up to date with training
By following these practices, healthcare workers protect themselves and their patients from many risks.

Conclusion
To conclude, understanding how are standard precautions different than universal precautions is essential in the field of healthcare. While universal precautions focus mainly on bloodborne pathogens, standard precautions cover a much wider range of infectious risks. Standard precautions include everything from hand hygiene to proper waste handling, making them more effective and complete.
They are used for all patients, all the time, ensuring better protection for both caregivers and patients. In today’s world, where new infections can spread quickly, following standard precautions is not just a rule but a responsibility. They form the foundation of safe medical practice and create a healthier environment for everyone involved in patient care.
