It is common for many easy-to-treat infectious diseases to be treated by a general practitioner. However, these specialists are usually consulted when a diagnosis is difficult to make or when treatment administration becomes difficult. Physicians who specialize in infectious disease use blood tests including an analysis of the patient’s blood serum, and X-rays. These doctors often use antibiotics to provide treatment to infected individuals when this is possible. They may administer these antibiotics in injection form to improve absorption. There are also antivirals and anti-fungal medicines that can be used to treat these illnesses. As an alternative, affected individuals may also have surgery and other procedures as treatment options.
These types of doctors also tend to have detailed knowledge of the types of sicknesses that are present in foreign countries, for which travelers must be prepared or against which they must be vaccinated. They are often able to educate potential travelers about these sicknesses and provide immunizations.
It is important for these specialists to be aware of the various ways that these infections can be transmitted. Some of the methods, depending on the type of illness, include skin-to-skin contact, contact with body fluids, or even the breathing in of water droplets. These doctors also are charged with eliminating the disease from the patient’s body and at the same time helping the body to recover. In the event that the sickness cannot be eliminated from the body, the specialist’s responsibility is to suppress the effectiveness of the agent causing the disease, limiting the damage done to the patient’s body and reducing the chances for its spread.
