A clinic responds to two possible routes of infection.
| Event | Information given to the clinic | Clinic response |
|---|---|---|
| 1 | Asha has chlamydia. Her recent sexual partner, Ben, has no symptoms. They had sexual contact without barrier contraception. | The clinic contacts Ben, offers him a chlamydia test and will give him antibiotics if the test is positive. |
| 2 | Callum shared injecting equipment with a person who later tested positive for HIV. The clinic tests Callum and finds that he has HIV. | The clinic supplies Callum with sterile injecting equipment and starts antiretroviral treatment. |
Explain how the information in each event supports the clinic's response, and how the response reduces the risk of further infections.
