Infectious Disease

Infectious disease can be caused by many pathogens, including bacteria, viruses, fungi, and parasites. The transmission of these pathogens can occur in a variety of ways: direct or indirect contact with a person or animal with the infection, food or water contamination, or insect bites. Infectious diseases are very common.


Diagnosis of infectious diseases can be done through a variety of laboratory tests. Samples of blood, sputum, urine, stool, tissue, or mucus may be taken.


Earlier diagnosis of an infectious disease can improve the effectiveness of treatments and long-term complications. Undiagnosed patients can unknowingly pass the disease to others, so diagnosis can prevent an outbreak.


Infectious diseases each have their own associated symptoms. General symptoms can include:
• Fever
• Diarrhea
• Fatigue
• Muscle aches
• Coughing
