How can I help you?

When should you see an infectious disease specialist?

Infectious Diseases focuses on evaluating, treating and preventing infectious illnesses.

  • Infections that recur or do not improve as expected.
  • Persistent fever that needs further evaluation.
  • Culture results or infections involving resistant organisms.
  • Infections in people with cancer or receiving treatments that suppress the immune system.
  • Evaluation and follow-up of tuberculosis, HIV and sexually transmitted infections.

Internal Medicine: a comprehensive approach

Adult medical care that considers the connections between symptoms, medical history and health conditions.

  • Evaluation of symptoms with several possible underlying causes.
  • Ongoing care for chronic conditions such as diabetes and hypertension.
  • A coordinated review of medications and complex medical conditions.
  • Preventive care and ongoing adult health follow-up.
  • Preoperative medical evaluation based on your procedure and medical history.

Your care plan is developed during the consultation and may be coordinated with other specialists.

For a medical emergency, go to an emergency department. The appointment WhatsApp line does not provide immediate care.

HIV prevention · Confidential care

PEP and PrEP assessment

Possible recent exposure to HIV?

Every hour counts: seek care as soon as possible, ideally within 24 hours and before 72 hours.

The consultation assesses risk, required testing and whether prophylaxis is indicated. If timely assessment is unavailable, go to an emergency department without waiting for a WhatsApp reply.

PEP is taken for 28 days. A negative rapid test cannot rule out recently acquired infection; we arrange appropriate testing and follow-up. Pending laboratory results should not delay the first dose.

Contact the office ↗

If the office does not respond immediately, go to an emergency department to avoid delaying assessment.

PrEP: prevention before an exposure

The visit includes individual assessment for HIV prevention and follow-up, as medically indicated. We review your history, required tests and follow-up plan.

HIV, including recent infection, must be excluded before starting PrEP. PrEP does not replace PEP after a recent exposure or prevent other sexually transmitted infections.

Outpatient intravenous antimicrobials · OPAT

For selected, clinically stable patients, intravenous antimicrobials can be administered at our office following assessment and with follow-up by an Infectious Diseases specialist.

An option to continue treatment after discharge or avoid a hospital admission when medically appropriate.

The right treatment for your recovery

We assess whether intravenous treatment is needed or an appropriate oral alternative is available. Not every infection requires intravenous medication.

Medication, duration, monitoring tests and follow-up are tailored to your progress. We can also assess continuation of treatment prescribed at hospital discharge or by your treating physician.
