“Most of the patients I care for come in with infections or fevers, often elderly individuals with existing chronic conditions such as high blood pressure, diabetes, or high cholesterol. Some present with bloodstream infections or severe infections, most of which are caused by common bacterial pathogens.” 

After graduating with a Doctor of Medicine degree from the Faculty of Medicine, Chulalongkorn University, Dr. Wisute further specialized by obtaining a board certification in Internal Medicine, with a subspecialty in Infectious Diseases from King Chulalongkorn Memorial Hospital. His inspiration and experience in this field are as follows: 

“I chose to study internal medicine because it’s a core specialty that allows me to care for a wide range of patients. The field itself is very broad and can branch into various subspecialties. I’ve always been drawn to the scientific aspect—using microscopes, studying pathogens, and tracking diseases. In Thailand, we frequently encounter viral, bacterial, and fungal infections, along with periodic outbreaks of diseases like dengue and influenza. I decided to pursue infectious disease as a subspecialty because I believe that having in-depth knowledge, skills, and expertise in this area would enable me to care for patients more effectively—especially with the emergence of new pathogens, like COVID-19, where staying updated through ongoing research is essential.” 

Investigate thoroughly for accurate diagnosis 

The work of an infectious disease specialist is similar to that of a detective—tracing the root cause of illness by identifying the pathogen involved. Each time he examines a patient, Dr. Wisute conducts a detailed medical history review to identify potential risk factors from recent activities. Infectious diseases can stem from travel to rural areas, forested or coastal regions, or even unnoticed insect bites. The patient’s context is crucial. 

In addition, standard physical examinations, blood tests, and cultures are performed to accurately confirm the diagnosis. Once all this information is compiled, it enables precise analysis and identification of the underlying cause—leading to targeted treatment. 

Treatment is the final step—Prevention is better 

Many infectious diseases can be prevented through vaccination, particularly for the elderly or those at higher risk. Key vaccines include those for influenza, pneumonia, shingles, diphtheria, pertussis, and tetanus. 

“That’s why it’s important to recognize the benefits and understand the value of disease prevention. Vaccination not only builds immunity and helps prevent infection, but also reduces the severity of the illness—far more effective than waiting to treat the disease after it occurs, which is already the final step.”
