What is the risk of infection after brief unprotected anal intercourse?

Seek emergency medical attention immediately if you experience any of the following:

• High fever or widespread chills
• Severe rectal pain or newly onset heavy bleeding
• Severe pain while urinating or inability to urinate
• Symptoms of fainting, prolonged dizziness, or loss of consciousness

These symptoms may indicate a serious condition; they require immediate evaluation without delay.

In some cases, the first few days after exposure are crucial. In particular, assessment of HIV risk may be time-constrained; consulting a specialist is necessary to confirm the risk.

• It is recommended to consult a sexual health/STD clinic, family doctor, or emergency room within the first 72 hours.
• Based on the risk assessment, the physician will recommend further referral or follow-up plans.

This information is for general guidance only; a definitive assessment should be made by a healthcare professional.

Depending on the exposure, an expert will conduct a risk assessment and plan appropriate tests. The timing of tests varies depending on the type of exposure.

• Some tests can be done immediately after exposure (for example, initial examination and some blood tests).
• For some infections, tests may need to be repeated weeks or months later due to window periods.
• Experts determine which tests are necessary and at what intervals they should be repeated.

Because the testing and follow-up plan may be individualized, it should be evaluated in the clinic.

For risk assessment, test plan, and guidance, you can choose one of the following services:

• Sexual health/STD clinics or reproductive health centers
• Infectious Diseases and Clinical Microbiology specialty services
• Family medicine or primary healthcare services

General, low-risk support recommendations and information on partner communication:

• Monitor your symptoms; seek medical attention if you notice any new or worsening symptoms.
• Seek advice from sexual health services regarding partner reporting and partner monitoring.
• Talk to an expert about future protection options and risk mitigation.
