Symptoms Following Exposure
After a needle stick injury, health care workers should be alert for symptoms of acute HIV. These include fever, sore throat, muscle aches, and a rash. These signs typically appear two to four weeks after exposure.
Importance of Monitoring
Regular monitoring is crucial after exposure to HIV. Testing for HIV should be done at baseline, six weeks, and four months post-exposure. This ensures any infection is caught early and treated promptly.

Other Potential Infections
Besides HIV, exposure can also lead to other infections like hepatitis B and C. The risk for these is even higher than for HIV, making it essential to monitor for any symptoms related to these infections as well.
