Many patients are referred to infectious disease specialists when an infection is difficult to diagnose, does not respond as expected to treatment, keeps returning, or requires specialized care.
An infectious disease doctor provides additional expertise for complex illnesses caused by bacteria, viruses, fungi, and parasites. These specialists review symptoms, medical history, previous treatments, laboratory findings, and other clinical information to help identify the cause of an infection and recommend an appropriate care plan.
The physicians at Infectious Disease Associates of Tampa Bay work with patients, primary care physicians, hospital teams, and other healthcare professionals to evaluate and manage a wide range of infectious diseases.
Not every infection requires specialist care. Primary care physicians and other healthcare providers successfully treat many common infections. However, a patient may be referred to an infectious disease specialist when an infection is severe, recurring, resistant to treatment, difficult to identify, or complicated by another medical condition.
Why would someone see an infectious disease doctor?
A patient may see an infectious disease doctor when an infection is severe, persistent, recurring, difficult to diagnose, or not improving with standard treatment. These specialists may also evaluate unexplained fevers, antibiotic-resistant infections, and infections affecting patients with weakened immune systems.
Understanding why patients are referred to infectious disease specialists, what these physicians treat, and what happens during an appointment can help patients prepare for the next stage of their care.
What Is an Infection Doctor Called?
A doctor who specializes in diagnosing and treating infections is called an infectious disease doctor or infectious disease specialist.
These physicians receive advanced training in illnesses caused by bacteria, viruses, fungi, and parasites. They may also help manage infections that affect multiple parts of the body, require prolonged treatment, or develop in patients with complex medical conditions.
An infectious disease doctor may:
- Review your symptoms and complete medical history
- Examine previous laboratory tests, cultures, and imaging
- Evaluate how you responded to earlier treatments
- Recommend additional diagnostic testing when appropriate
- Select or adjust antibiotic, antiviral, antifungal, or antiparasitic treatment
- Monitor treatment response and possible medication effects
- Coordinate care with your primary care physician, surgeon, or hospital team
- Help develop an infection prevention or follow-up plan
The specific evaluation and treatment recommendations will depend on your symptoms, diagnosis, medical history, and individual clinical needs.
What Does an Infectious Disease Specialist Treat?
An infectious disease specialist can treat a wide range of conditions. These are some of the key infections and diseases that an infectious disease doctor may evaluate or help manage:
- Persistent or recurring infections
- Severe bacterial infections
- Fungal and parasitic diseases
- Viral illnesses
- Antibiotic-resistant infections
- HIV/AIDS and immune-related conditions
- Unexplained or persistent fevers
- Bloodstream infections
- Bone and joint infections
- Respiratory infections
- Skin and soft tissue infections
- Wound infections
- Travel-related infections
- Infections affecting immunocompromised patients
If you have one of these conditions and have experienced little or no improvement from prior treatment, your healthcare provider may recommend working with an infectious disease specialist.
The specialist can review your medical history and previous test results, evaluate possible causes, and develop a treatment plan based on the available clinical evidence. Some complex or severe infections may benefit from consultation between an infectious disease specialist and the patient’s existing care team.
Common Reasons for a Referral to an Infectious Disease Specialist
There are many reasons why a patient may receive a referral to an infectious disease specialist. A referral does not necessarily mean that a patient has a rare or highly contagious disease.
In many cases, the referring physician wants additional expertise to identify the cause of an infection, select an appropriate medication, or manage a condition that requires closer monitoring.
The following are some of the most common situations in which a patient may be referred for infectious disease care.
Recurrent or Persistent Infections
Patients may be referred to an infectious disease specialist when infections keep returning or symptoms continue despite antibiotic treatment.
Examples may include:
- Recurrent urinary tract infections
- Repeated skin infections
- Persistent respiratory infections
- Slow-healing wound infections
- Unexplained or recurring fevers
- Infections that temporarily improve and then return
The specialist may review previous cultures, medications, and treatment responses to determine whether additional testing or a different care approach should be considered.
Recurring symptoms do not always indicate an active infection. A detailed evaluation can help the care team distinguish between an infection and another condition that may cause similar symptoms.
Complex or Severe Infections
Infectious disease doctors often evaluate complex and severe infections, including pneumonia, bloodstream infections, bone and joint infections, and serious skin and soft tissue infections.
These infections may require support from multiple healthcare professionals, especially when they affect more than one part of the body, require hospitalization, or occur alongside another medical condition.
An infectious disease specialist can work with your primary care physician, surgeon, hospital physician, or other members of your healthcare team to help coordinate testing, medication selection, and follow-up care.
Infections That Are Difficult to Diagnose
Some patients continue to experience symptoms even when the initial cause is unclear. A referral may be appropriate when routine testing does not provide a clear diagnosis or when several possible conditions need to be considered.
An infectious disease specialist may review:
- The timing and pattern of symptoms
- Previous laboratory and culture results
- Imaging reports
- Recent hospitalizations or procedures
- Travel history
- Animal, occupational, or environmental exposures
- Medications and earlier antibiotic use
- Existing health conditions
- Possible immune system concerns
This detailed review can help determine whether additional infectious disease testing or consultation with another specialist may be useful.
Antibiotic-Resistant Infections
Specialists can help manage infections caused by bacteria that are resistant to one or more commonly used antibiotics, including methicillin-resistant Staphylococcus aureus, also known as MRSA.
An infectious disease doctor may use culture and susceptibility results to identify the organism and determine which medications may remain effective. Treatment decisions depend on the type of bacteria, the location and severity of the infection, and the patient’s overall health.
Because unnecessary or inappropriate antibiotic use can contribute to resistance, patients should take antibiotics only as directed by a qualified healthcare professional.
IV Antibiotics and Infusion Therapy
Some infections require intravenous antibiotics rather than oral medication. IV antibiotics deliver medication directly into the bloodstream through intravenous access.
An infectious disease specialist may recommend IV antibiotic treatment when oral medication is not appropriate, the infection is severe, or the medication needs to reach a specific concentration in the body.
Depending on the patient’s condition and treatment plan, antibiotic infusion therapy may be provided through an outpatient program. Infectious disease specialists can monitor treatment response, review laboratory results, and adjust the medication or treatment duration when medically appropriate.
Patients receiving infusion therapy may need regular follow-up appointments to monitor:
- Symptoms and recovery
- Laboratory results
- Medication effectiveness
- Possible side effects
- IV access or infusion-related concerns
- Whether treatment should continue or change
Not every infection requires an antibiotic infusion or IV antibiotics. The appropriate treatment route should be determined by a qualified healthcare professional based on the patient’s diagnosis and clinical needs.
HIV/AIDS Care
Patients living with HIV may see an infectious disease specialist for long-term care and monitoring.
An infectious disease physician may provide support with:
- Antiretroviral medication management
- Routine laboratory monitoring
- Treatment response
- Medication interactions
- Prevention and management of opportunistic infections
- Ongoing education and preventive care
- Coordination with other healthcare providers
Consistent medical care can help patients manage HIV as a long-term condition. Learn more about HIV care at IDATB.
Immunocompromised Patients
Individuals undergoing chemotherapy, organ transplantation, or immunosuppressive treatment may receive a referral to an infectious disease specialist as part of their broader care plan.
Patients with weakened immune systems may have a higher risk of certain infections or may experience symptoms differently from people with healthy immune systems.
An infectious disease specialist may help with:
- Infection evaluation
- Prevention planning
- Medication selection
- Monitoring during immunosuppressive treatment
- Evaluation of fever or other possible infection symptoms
- Coordination with oncology, transplant, or other specialty teams
The exact care plan will depend on the patient’s immune status, underlying condition, and current treatment.
Does Every Infection Require an Infectious Disease Specialist?
No. Many common infections can be diagnosed and treated by a primary care physician, urgent care clinician, or another appropriate healthcare provider.
An infectious disease evaluation may be considered when:
- An infection is not improving as expected
- Symptoms continue after treatment
- The infection repeatedly returns
- The cause remains unclear
- The organism is resistant to standard medications
- The infection is severe or affects multiple body systems
- The patient has a weakened immune system
- Specialized antimicrobial treatment is being considered
- IV antibiotics or extended treatment may be needed
- The referring healthcare provider wants additional clinical guidance
The decision to involve an infectious disease specialist should be based on the patient’s individual medical situation. Patients should not stop or change an existing medication without guidance from the prescribing healthcare professional.
Signs You May Need an Infectious Disease Evaluation
If you are unsure whether you need an infectious disease evaluation, certain symptoms or clinical situations may prompt your healthcare provider to consider a referral.
These may include:
- A fever with no identified cause
- An infection that does not improve with treatment
- Symptoms that return after antibiotics are completed
- Repeated skin or urinary tract infections
- Slow-healing wounds
- Persistent respiratory symptoms
- Chronic fatigue associated with a suspected infection
- Repeated hospitalizations for infection
- Abnormal cultures or laboratory results
- A suspected infection after surgery or another medical procedure
These symptoms do not automatically mean that you have a complex infection or require specialist care. Several infectious and noninfectious conditions can cause similar symptoms.
A qualified healthcare professional can determine whether additional testing, an infectious disease consultation, or another type of evaluation is appropriate.
When to Seek Urgent or Emergency Medical Care
A routine infectious disease appointment is not a substitute for emergency care.
Seek immediate medical attention for severe or rapidly worsening symptoms, including difficulty breathing, chest pain, confusion, fainting, severe weakness, signs of shock, or another potentially life-threatening condition.
Patients who are unsure whether a symptom requires urgent care should contact an appropriate healthcare professional or emergency service.
What to Expect During Your Infectious Disease Appointment
Appointments may include several steps to support diagnosis and future treatment.
Your initial appointment will usually begin with a detailed review of your symptoms and medical history. The specialist may also ask when the symptoms began, how they have changed, and which treatments you have already received.
The infectious disease doctor may review:
- Previous antibiotic or antimicrobial treatments
- Current medications and supplements
- Medication allergies
- Laboratory and culture results
- Imaging reports
- Hospital or surgical records
- Existing health conditions
- Recent travel
- Occupational, environmental, or animal exposures
- Relevant family or household illness history
The first appointment may lead to diagnostic testing or a medication evaluation. The specialist may recommend blood tests, cultures, imaging, or other tests depending on the patient’s symptoms and clinical history.
Testing is not identical for every patient. Some people may already have enough recent information in their medical records, while others may need additional evaluation before a diagnosis or treatment recommendation can be made.
Once the specialist has reviewed the available information, they can develop a personalized treatment plan. If needed, the infectious disease physician may coordinate with other healthcare providers who are already involved in your care.
You may need follow-up appointments to evaluate whether the medication is working, review test results, and make adjustments when medically appropriate.
What Should You Bring to Your First Appointment?
Preparing your records before your appointment can help the infectious disease specialist understand your medical history and avoid unnecessary delays.
Bring the following items when available:
- Your physician referral or consultation request
- A list of current medications and supplements
- A list of medication allergies
- Previous laboratory and culture results
- Imaging reports or access instructions
- Hospital discharge documents
- Surgical or procedure records
- A list of previous antibiotics or antimicrobial medications
- The dates and duration of earlier treatments
- A written timeline of your symptoms
- Relevant travel or exposure information
- Insurance information and identification
- Questions you want to ask the physician
If another physician has already performed testing, ask whether those records should be sent to the infectious disease office before your appointment.
Do You Need a Referral to See an Infectious Disease Doctor?
Referral requirements can vary based on the service being requested, the patient’s insurance plan, and the practice’s scheduling policies.
Some patients are referred by:
- Primary care physicians
- Hospital physicians
- Surgeons
- Oncologists
- Transplant teams
- Wound care providers
- Other medical specialists
Before scheduling, contact the infectious disease practice and your insurance provider to confirm whether you need a physician referral, prior authorization, or specific medical records.
Confirming these requirements in advance can reduce scheduling delays and help ensure that the specialist has the necessary information before the visit.
