Who are infectious disease specialists?
Many bacteria, fungi, viruses, and pathogens reside in the human body. They are generally harmless. However, some microorganisms can cause infections and diseases. Some of these infection-causing beings are germs that enter the body from the outside. Common ways to contract such infection-causing pathogens are eating contaminated food or physically contacting certain insects, animals, other infected persons, or their belongings.
Infectious disease specialists hold expertise in diagnosing and treating such conditions, which may range from common cold to flu to pneumonia. They most frequently address pneumonia, sexually transmitted diseases, urinary tract infections, hepatitis B and C, skin infections, wounds that are not healing or are infected, human immunodeficiency virus (HIV), etc. Apart from attending to these issues, an infectious disease specialist can also provide international travel care. They administer shots and vaccines for diseases like tetanus or whooping cough and treat conditions contracted during travel, like dengue, malaria, tuberculosis, etc.
An infectious disease specialist can also impart infusion care in an outpatient setting by offering antibiotics, antifungals, iron therapy, osteoporosis therapy, hydration therapy, immunoglobulins, steroids delivered via intravenous (IV) infusion, etc. They can also help manage a surgical site or hospital-acquired infection such as sepsis. An infectious disease doctor also counsels people who engage in high-risk sexual behavior.
Education and training of an infectious disease specialist
Infectious disease specialists receive ten years of specialized education to develop clinical and laboratory skills.
Their educational journey begins with four years of medical school, where they learn about general internal medicine, microbiology, tropical diseases, etc. They acquire at least three more years of training as an internal medicine doctor, following which they undergo specialty training in infectious diseases. Lastly, they begin their practice after clearing an examination held by the American Board of Internal Medicine (ABIM).
These specialists' training continues throughout their practice to help them better understand newer infectious diseases that result from inter-country travel or increasing rates of antibiotic resistance.
In what ways do infectious disease specialists work with other physicians?
Infectious disease specialists can be found in distinct work environments based on their focus. Those in clinical settings diagnose and treat infectious disease patients operating within hospitals or specialized clinical facilities. Their work involves extensive direct interaction with patients and healthcare colleagues.
In contrast, specialists in public health concentrate their efforts in laboratory and research settings. Their responsibilities encompass researching new disease strains, analyzing population data, and disseminating findings to the scientific community and the broader public.
In hospitals, infectious disease specialists collaborate closely with various healthcare professionals. While hospitalists typically manage the overall care of hospitalized patients, they may seek consultation from ID specialists for complex cases involving infectious diseases. In such situations, the hospitalist remains the primary physician overseeing the patient's care, while the ID specialist focuses on managing the infectious aspect, adjusting antibiotic and antifungal treatments as needed.
In outpatient clinics, ID physicians often see patients referred to them, such as those identified with potential infectious conditions, by primary care physicians like family medicine doctors or GPs. For instance, if elevated liver enzymes are detected during routine screening, prompting further investigation for hepatitis, the patient might be referred to an ID specialist. In the clinic setting, the ID specialist conducts a comprehensive evaluation, including assessing liver damage, hepatitis viral load, and viral strain. Upon completion of diagnostic tests, treatment for hepatitis can commence, often resulting in complete eradication of the virus within approximately two months due to advancements in treatment protocols.
What treatments can an infectious disease specialist prescribe?
The treatments an infectious disease specialist can provide depend on the disease's causative or germ. Generally, they recommend the following four types of medications:
- Antibiotics: These treat bacterial infections and are ineffective for viral ones. Infectious disease specialists prescribe targeted antibiotics once they know what type of bacteria has infected the patient. Over time, however, overuse of antibiotics has resulted in many bacteria developing resistance to them, making the conditions harder to treat.
- Antifungals: These specialists mainly recommend antifungals as creams to treat fungi-induced nail or skin infections. They administer oral antifungals to combat fungal infections that affect the lungs or mucous membranes. For people with weakened immune systems, developing severe fungal infections in the internal organs may require intravenous antifungal medications.
- Antivirals: Many drugs symptomatically treat viral infections, but only a few cures are available. Infectious disease specialists may prescribe antivirals for herpes, influenza, hepatitis B, hepatitis C, human immunodeficiency virus, etc.
- Anti-parasitics: Diseases like malaria, caused by tiny parasites, can be treated using anti-parasitic drugs. However, some parasites have now developed resistance to these drugs.
- Lifestyle changes and home remedies can also benefit certain infectious diseases, such as colds, that often resolve independently. One can take care of the most common infections by simply getting sufficient rest and drinking plenty of fluids. Alternative medicine is known to boost the immune system and treat certain illnesses. Garlic, cranberry, vitamins C and D, zinc, ginseng, etc., are some ingredients that prevent or shorten the duration of an infection. However, this varies from case to case, and one should rely on them only after checking in with an infectious disease doctor.
Why should one visit an infectious disease specialist?
While primary care physicians can handle many infections, there are scenarios where consulting an infectious disease doctor is vital. They are crucial in healthcare for various conditions and concerns, such as:
- Diagnosis challenges: Many contagious diseases exhibit similar symptoms, making precise identification difficult. Infectious disease doctors possess expertise in performing and interpreting tests to pinpoint the exact cause of an illness.
- Specialized treatment: These specialists can manage antibiotic-resistant infections, a growing healthcare concern requiring specialized care.
- Autoimmune diseases: Those with autoimmune disorders may benefit from an infectious disease specialist's insights.
- Recurring high fever: A persistently high fever often indicates a severe infection possibly linked to a weakened immune system. Infectious disease specialists can provide tailored treatment in such cases.
- Hospital-acquired infections: Infectious disease specialists can guide and oversee your care for infections contracted in a hospital.
- Chronic infections: Lifelong or long-term infections like HIV/AIDS, tuberculosis, and hepatitis demand ongoing care. These diseases can be life-threatening or severely impact daily life without continuous specialized attention.
- International travel: Anticipated travel to regions with unique infectious risks warrants consultation with these specialists.
What should you expect when visiting an infectious disease specialist?
When you visit an infectious disease specialist near you, the process begins with a detailed analysis of your medical history and a physical examination. During your visit, expect them to ask questions about your symptoms, such as when they started, their severity, and any potential triggers. They might inquire about recent contact with sick individuals, animal interactions, insect bites, and dietary habits. If you have traveled abroad recently, that could be relevant too.
Based on this assessment, they may recommend various tests, including blood and urine analyses, throat swabs, stool samples, spinal taps, imaging scans, or tissue biopsies. If your condition requires specialized care, the infectious disease specialist may collaborate with or make referrals to other experts like dermatologists or pulmonologists. If needed, you may have to visit the specialist for follow-ups.
Bring all your relevant medical records, including X-rays, lab reports, and immunization history, to ensure a productive visit. Remember to disclose any allergies and medications, including birth control pills, as these can interact with antibiotics. This comprehensive approach ensures that your doctor can diagnose accurately and develop an effective treatment plan.
How can you prevent infectious diseases?
There are many ways to prevent the risk of transmitting infectious diseases. While there's no single way to 100% prevent all infections, each step that you take to reduce the risk of spreading contagious diseases acts as a layer of protection. This is called the "Swiss Cheese Model," first introduced by James Reason, PhD. It demonstrates that even if the protection is not perfect (one layer of cheese has holes), the more layers of protection (or the slices of cheese) you add, the more you can lower the chances of contracting and/or spreading infectious diseases. Examples of layering protection include steps like vaccination, washing your hands, safe food handling, cleaning, and disinfecting.
Adopting the following habits and sensible actions in your daily life can be the strongest defenses against infectious diseases:
- Getting timely vaccinations and immunizations: Training the immune system to fight off harmful pathogens in the body can be done by a vaccine- an agent that is similar to a disease-causing microbe and is often made from weakened or killed forms of the microorganism or its toxins. The immune system then recognizes this agent as foreign and destroys it. Our immune system also remembers these weakened microbes so that it can more easily identify them in subsequent encounters. Vaccines are available in the United States for conditions like polio, measles, COVID-19, chicken pox, whooping cough, diphtheria, malaria, influenza, and more. Additionally, ensure that your pet is vaccinated, too.
- Always practice good hygiene: This includes washing your hands before preparing food and after blowing your nose, coughing, sneezing, or visiting or caring for a sick individual, and feeding or stroking your pet. Avoid sharing dishes, utensils, and napkins with others.
- Adopt these essential food safety measures: Always prepare and store food safely to avoid getting sick. While getting infections from food-borne pathogens can be treated, in some cases, these infections may lead to severe and life-threatening medical conditions, such as kidney failure or meningitis. Wash all raw meat, poultry, fruits, and vegetables, and make sure you separate raw and cooked foods. Defrosting food should ideally be done in the refrigerator or a microwave.
- Be safe while traveling: While traveling to an unknown destination can be highly exciting, it's essential to take the proper precautions and inform yourself about the location before you proceed with your travel plans. This includes understanding the local climate, insects and parasites, and sanitation of the place. Visit your physician about four to six weeks before the trip to understand if you need any specific vaccinations. The CDC provides a list of certain countries that require proof of vaccinations before you enter the country.
