Prevention and Treatment of Infectious Diseases:

Infectious Disease Specialists at Sims Hospital treat several specific symptoms that can be caused by infectious diseases. In the prevention and treatment of infectious diseases, antibiotics and antivirals play an important role. Antibiotics are strong medicines that fight against the bacterial infection by stopping them to reproduce or kill bacteria. We appear to stimulate the normal immune system of the body to function and respond to the pathogens in order to eliminate them. Applying proper dosage and prescribed antibiotics by the physician can save lives, but antibiotics are not effective against viral infections such as common cold or flu. In such cases, the doctor or physician prescribes antiviral drugs to combat the infection by inhibiting viral reproduction.
