Can a cut and touching blood on a phone cause HIV infection?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I was using my driver's mobile phone, and his screen was totally broken. After a few minutes, I noticed a cut on my finger. If there was blood already on the screen and if I got a cut and there was a little bleeding on my finger, then can I get HIV (human immunodeficiency virus) in this situation? Should I get tested?

Please guide.

Thank you.

Answered by Dr. Kakkar

Hello,

Welcome to icliniq.com.

I have noted your concern.

There is no risk of HIV (human immunodeficiency virus). Firstly, the virus does not survive outside the body for more than a few seconds and dies quickly on drying.

Moreover, a minor cut does not provide direct access to the virus in the blood. It has to be a fresh, deep, actively bleeding wound for the virus to gain access to the bloodstream.

I hope this information will help you.

Thank you.

Patient's Query

Hello doctor,

Thank you for the reply.

Even if there were some blood or semen stains on the phone screen, and I got a cut, and there was some bleeding from my finger, then also, is there no chance at all that I could get HIV?

Please suggest.

Thank you.

Answered by Dr. Kakkar

Hello,

Welcome back to icliniq.com.

I can understand your concern.

HIV cannot survive in dried blood or semen. So, the stains are not infectious.

I hope this information will help you.

Thank you.

Patient's Query

Hello doctor,

Thank you for the reply.

You said dried blood. What if there was wet blood on the screen? Because it was dark and I do not know.

Please help.

Thank you.

Answered by Dr. Kakkar

Hello,

Welcome back to icliniq.com

I can understand your concern.

Even if we assume that there was some fresh blood on the phone, then also there is no risk because a minor cut on your finger would not provide access to the virus into the bloodstream. It has to be a deep, fresh, actively bleeding wound, such as a laceration, for the virus to get access to the bloodstream.

To be sure, you can ask your driver if he has sustained any fresh bleeding wounds that you think might have contaminated the phone.

I hope this information will help you.

Thank you.

Patient's Query

Hello doctor,

Thank you for the reply.

I asked him. The driver said that he got some cuts a few days ago. Also, I would like to tell you that I have become very paranoid when it comes to HIV (human immunodeficiency virus).

Are you sure I am at no risk here at all? Do I need testing?

Please suggest.

Thank you.

Answered by Dr. Kakkar

Hello,

Welcome back to icliniq.com.

I can understand your concern.

There is no risk. Your driver said that he got cut on his finger a few days ago. So, that means his wound was not bleeding when you used his phone, and the virus would not have survived on his phone for a few days after he sustained the wound on his fingers. I do not think that you should worry about HIV.

I hope this information will help you.

Kindly follow up if you have more concerns.

Thank you.

Patient's Query

Hello doctor,

Thank you for the reply.

Also, after I came home, I used spirit to clean the cut. It burnt a little. Does the burning state indicate that the wound was deep?

Please suggest.

Thank you.

Answered by Dr. Kakkar

Hello,

Welcome back to icliniq.com.

I can understand your concern.

No. A burning sensation to the spirit can be felt in a very superficial wound as well.

I hope this information will help you.

Thank you.

Patient's Query

Hello doctor,

Thank you for the reply.

So, I should not worry at all about HIV in this situation, right? No need for testing?

Please suggest.

Thank you.

Answered by Dr. Kakkar

Hello,

Welcome back to icliniq.com.

I can understand your concern.

I do not think there is any need for testing in the scenario you mentioned. Let me know if you have any more doubts or skin-related concerns.

I hope this information will help you.

Thank you.

Patient's Query

Hello doctor,

Thank you for the reply.

So, one last question. What if there was wet blood on the screen, and I got a cut, and there was some bleeding, and let us say very little blood of his entered through my small cut? But you said that the cut should be big and very deep, right?

How long can HIV survive in wet blood outside the body?

Please suggest.

Thank you.

Answered by Dr. Kakkar

Hello,

Welcome back to icliniq.com.

I can understand your concern.

If fresh contaminated blood enters the bloodstream, then it is definitely considered an HIV infection. However, this usually does not happen because it is a rare scenario that a profusely bleeding HIV-positive person's blood would come in contact with the deep, fresh, bleeding wound of a healthy person. A small bleeding cut does not provide direct access because the bleeding capillaries constrict as soon as they are traumatized.

Moreover, the blood is flowing out of the vessel. So, unless it is a large bleeding wound and fairly large contamination occurs with the virus-infected blood, the virus cannot get into the bloodstream. The virus does not survive more than a few seconds and certainly not in dried blood. It dies on exposure to air.

I hope this information will help you.

Thank you.

Patient's Query

Hello doctor,

Thank you for your reply.

How long does it take for wet blood to dry in the outside environment or at room temperature? Approximately?

Please suggest.

Thank you.

Answered by Dr. Kakkar

Hello,

Welcome back to icliniq.com.

I can understand your concern.

It depends on the amount of blood. It might take 10 to 15 minutes for a few drops to dry. However, the virus dies sooner outside the body than inside. It dies quickly on exposure to air.

I hope this information will help you.

Thank you.
