Is hiv transmitted through bite and scratch from infected person?

Although the primary modes of HIV transmission are unprotected sexual intercourse, sharing contaminated needles or other drug paraphernalia, and mother-to-child transmission, HIV can also be transmitted through bites or scratches from an infected person. However, the risk of HIV transmission through bites or scratches is generally considered low.

For HIV transmission to occur through a bite or scratch, several factors must be present:

- The infected person must have a high viral load, which means a high concentration of HIV in their blood or saliva.

-The bite or scratch must be deep enough to draw blood and allow contact between the infected person's blood or saliva and the open wound of the uninfected person.

-There must be a significant amount of infected blood or saliva transferred during the bite or scratch.

-The uninfected person must have a compromised immune system or other factors that make them more susceptible to HIV infection.

Even when these factors are present, the risk of HIV transmission through a bite or scratch is relatively low. Studies suggest that the risk of transmission from a single bite or scratch is less than 0.1%. However, the risk increases if there is significant bleeding, multiple bites or scratches, or if the bite or scratch occurs in an area with a high concentration of blood vessels, such as the face, neck, or genitals.
