I'm Dr. Antônio Guilherme Baylão, an infectious disease specialist. If you've been living with unexplained fevers, infections that keep coming back, a bone or joint infection, or a weakened immune system, these are exactly the cases I dig into. I see patients in person in Rio de Janeiro and São Paulo, and by telemedicine across Brazil.
I am Dr. Antônio Guilherme Baylão, an infectious disease physician practicing in the office, in hospitals and in infection prevention and control in Rio de Janeiro and São Paulo. I devote my practice to cases that demand deep investigation: bone and joint infections and those associated with prostheses and implants, invasive fungal infections, complex wounds, and the care of immunosuppressed and onco-hematology patients.
I am currently an ID physician at the UNIMED Volta Redonda Hospital and its Home Care Service (SAD), and also at the Viver Mais Hospital & Medical Center. My path combines the office, the bedside and teaching — residency preceptor in Infectious Diseases, consultant in complex infections and antimicrobial stewardship, with active participation in clinical research and in national and international scientific societies.

Fees are informed at booking, via WhatsApp or on the online calendar. We accept Pix and credit card. Private consultations can generate a receipt for reimbursement from your health plan.
Care is private. Many plans reimburse specialist consultations — we provide all the documentation you need to request yours.
Bring all tests already performed (even old ones), your current medication list, reports from previous hospitalizations and, if possible, a timeline of your symptoms. The more information, the more precise the investigation.
Mentorship can be individual or in a group, with regular online meetings for real-case discussion, diagnostic reasoning and ID management. Message us on WhatsApp to learn about the format, schedule and pricing of upcoming cohorts.
