Infectious Diseases
Infectious diseases are diseases caused by biological agents, such as viruses, bacteria or parasites. An infectious disease is contagious if it is easily transmitted from one person to another. An infectious diseases specialist diagnoses and provides therapy for an infectious disease. He or she also works with patients and doctors, as well as laboratory scientists and immunologists.
THE FIGHT WITH BACTERIA
Bacteria: Harbinger of Bad News
Bacteria infection and growth can result in diseases that range from respiratory diseases to sexually transmitted diseases (STD). Ably transmitted via physical contact, the contamination of food and airborne inhalation, bacteria is a dangerous agent that is easily passed on. Infectious diseases caused by bacteria can be fought off by the body's immune system.
Shield Yourself the Right Way
Consult a medical practitioner for prescription of antifungal and antiviral medication and antibiotics. If detected and applied during the early stages of bacterial infection, these antibodies are able to speed up the process and eliminate any existing bacterium in the body system. Regular vaccinations, washing your hands before meals and after visits to the bathroom, practicing safe sex and staying at home while you are ill can also prevent the transmission of bacteria.
Situations When an Infectious Disease Specialist is Needed
- The disease has not been definitively diagnosed after an initial workup
- The patient’s immune system is compromised (e.g., AIDS, or after undergoing chemotherapy)
- The infectious agent is uncommon (e.g. tropical diseases, fungal infections)
- The disease has not responded to antibiotics
- The disease might be dangerous to other patients, and the patient might have to be isolated (e.g. SARS)
Common Infectious Diseases
- Viral Infectious Diseases (e.g., AIDS, Chickenpox, Colds, Dengue Fever, Hand, foot and mouth Disease, Hepatitis, Herpes Zoster, Measles, Mumps, Rubella, SARS, Smallpox, Viral meningitis)
- Bacterial Infectious Diseases (e.g., Anthrax, Cholera, Leprosy, Lyme Disease, Syphilis, Tetanus, Tuberculosis, Typhoid Fever, Whooping Cough)
