Seeing someone injured in a car accident, I touched blood while helping?

Hello Doctor: Yesterday evening, I witnessed a car accident where someone was lying on the ground with an injury to the left side of their head, bleeding profusely.
There was a pharmacy nearby, so I bought some gauze and, while the injured person was slightly moving their head, I took the opportunity to place the gauze on their injury.
During this process, I came into contact with their blood, which was approximately the volume of half a bottle of yogurt drink.
My hands have been itching a lot lately, and I have been scratching them, but I don't feel any open wounds.
After waiting for the ambulance to arrive and the injured person was placed on a stretcher, my hands were covered in dried blood, and I washed them afterward.
Should I undergo any tests? Thank you for taking the time to respond, Doctor.

Dear Miss Xiao Li:
1.
If the skin that comes into contact with your hand has no wounds, then the possibility of infection from exposure to blood or serum is negligible; human skin serves as the first line of immune defense.

2.
The so-called serological infectious diseases mainly include HIV, Hepatitis B, Hepatitis C, and Syphilis.
3.
In clinical practice, when healthcare workers experience accidental needle sticks or cuts, we assess whether the injured person has any of the aforementioned diseases.
If they do, necessary remedial measures are taken.
However, since you do not have any wounds, theoretically, there is no need for concern.
4.
Furthermore, if you have any additional questions, please discuss them in detail with your family physician or a trusted doctor.

More Info

In the unfortunate event of witnessing a car accident and providing first aid, it is essential to understand the potential health risks involved, especially when coming into contact with blood. Your concern about touching the victim's blood is valid, and it is important to take appropriate steps to ensure your health and safety.

Firstly, it is crucial to recognize that blood can carry various pathogens, including viruses and bacteria. The most notable concern is the transmission of bloodborne pathogens such as Hepatitis B, Hepatitis C, and Human Immunodeficiency Virus (HIV). However, the risk of transmission depends on several factors, including the presence of open wounds on your skin, the volume of blood you came into contact with, and the health status of the injured person.

In your case, you mentioned that your hands were not visibly broken or bleeding, which significantly reduces the risk of infection. If you have no open cuts or abrasions, the likelihood of contracting an infection from touching the blood is low. However, it is still advisable to take certain precautions:
1. Wash Your Hands: As you did, it is essential to wash your hands thoroughly with soap and water as soon as possible after coming into contact with blood. This helps to remove any potential pathogens.

2. Monitor for Symptoms: Keep an eye on your health for any unusual symptoms that may arise in the following weeks. Symptoms of bloodborne infections can vary but may include fever, fatigue, jaundice (yellowing of the skin and eyes), or flu-like symptoms. If you experience any of these, seek medical attention promptly.

3. Consider Testing: While the risk is low, if you are particularly concerned or if the victim is known to have a bloodborne infection, it may be wise to consult a healthcare provider about the possibility of testing for Hepatitis B, Hepatitis C, and HIV. They can provide guidance on the appropriate timing for testing, as some infections may not be detectable immediately after exposure.

4. Vaccinations: If you are not already vaccinated against Hepatitis B, consider discussing vaccination with your healthcare provider. Vaccination can provide protection against this virus.

5. Seek Professional Advice: If you have any lingering concerns or if you develop any symptoms, do not hesitate to reach out to a healthcare professional. They can provide personalized advice based on your specific situation.

In summary, while touching blood in a first aid scenario can be concerning, the risk of infection is relatively low, especially if you did not have any open wounds. Taking immediate action by washing your hands and monitoring your health is the best course of action. If you have any doubts or experience symptoms, consulting a healthcare professional is always a prudent step. Your willingness to assist the injured person is commendable, and ensuring your own health is equally important.
