The right care when it matters most

Infectious diseases

Infectious diseases are those caused by bacteria, viruses, fungi or parasites. Most of the time, these infections are treatable at home or with medications provided by your primary care doctor.

Sometimes infections can be medically complex to treat — whether they’re rare or emerging conditions or resistant to standard treatments. That’s where an infectious diseases specialist comes in. These specialty-trained doctors use the latest research to treat challenging infections and keep them from spreading.

We treat a full spectrum of infectious diseases, including:

  • Abscesses, boils
  • Antibiotic-resistant infections
  • Bone and joint infections
  • Cellulitis
  • Complicated pneumonia
  • COVID-19
  • Encephalitis
  • Fevers of unknown origin
  • Fungal infections
  • Hepatitis
  • HIV/AIDS
  • Influenza (flu)
  • Lyme disease
  • Meningitis
  • Mpox (monkeypox)
  • MRSA (methicillin-resistant staphylococcus aureus) and other staph infections
