Final answer:
Blood-borne infections can occur through skin abrasions when the skin's protective barrier is compromised and comes into contact with infected body fluids.
Step-by-step explanation:
One can be affected by a blood-borne infection via a skin abrasion if they come into contact with infected body fluids, such as blood, semen, or saliva.
Skin is a natural barrier against pathogens, and any breach can allow microbes to enter. In the healthcare setting, the risk of transmission is significant due to frequent exposure to blood and other body fluids.
Health-care workers must hence take caution by wearing gloves, face protection, and utilizing disposable syringes.
In the event of an exposure, post-exposure treatments like the hepatitis B immunoglobulin (HBIG) and vaccination can be administered.
Additionally, prompt cleaning of wounds with soap and water is recommended, and disinfecting surfaces with a solution such as 10% bleach can help prevent the spread of infection.
In scenarios such as tattoos and piercings, where skin penetration occurs, strict hygiene and sterilization protocols are critical to prevent blood-borne diseases like tetanus, hepatitis C, and hepatitis D.
