I am HIV+ , the other day I scratched my wound and touched my computer mouse someone touched the same mouse after some time can HIV spread this way?
Thank you for your inquiry. From what we gather from the question, you were asking about the possibility of HIV transmission if you (a person living with HIV) touches an item, and a person who is not living with HIV subsequently touches said item after you. From the information given, this scenario is determined to be No Risk (transmission of HIV is not possible in the given scenario).
HIV transmission occurs when an individual living with HIV has bodily fluid that comes into contact with an individual with HIV negative status having direct access to the bloodstream through a High Risk activity.
In this scenario there is No Risk (transmission of HIV is not possible in the given scenario) for HIV transmission. You stated scratching your wound then touching a computer mouse. The other person later touching the mouse would need an open wound/cut that is currently bleeding for bodily fluid to be considered coming into contact with their bloodstream. It is important to note that when bodily fluid containing HIV is exposed to the environment it quickly becomes inactive. Therefore if there was bodily fluid on the mouse it is highly unlikely that HIV could have been transmitted to another individual.
As you are living with HIV it is important to adhere to a regular treatment schedule in order to ensure a longer and better quality of life. If you are newly diagnosed it is important to connect with medical care right away (1). An important option for you to consider is to take medicine called ART (antiretroviral therapy). ART when taken daily can make your viral load undetectable (1). If you maintain an undetectable viral load then you are not putting others at risk of acquring HIV (1).
It is worth noting as well, that HIV is not transmitted through hugs, hand-shakes, toilet seats, sharing drinks/food, or other casual contact. You may also find our HIV Transmission Equation to be a helpful tool to assessing HIV risk.
Protective measures taken in order to lessen the risk of HIV transmission to others include: take ART, never used shared needles. always use a condom or protective measure the right way when engaging in sexual activities, and get tested and treated for sexually transmitted infections (1). Please talk to your physician if you have further questions in regard to HIV treatment.
Recommendation: No need for HIV test with the scenario provided, refer to a physician for other health related questions.
