Infectious Diseases

Infectious diseases are disorders caused by organisms like bacteria, viruses, fungi or parasites and many organisms. They're normally harmless or maybe helpful. But under certain conditions, some organisms may cause disease. Described as contagious, they will be passed from person to person through body secretions, insects or other means. You’ll be able to acquire an infection in many various ways, like directly from an individual with an infection, via contaminated food or water, and even through the bite of an insect. Following exposure to an infected animal that harbors a pathogenic organism that is able to infect humans, humans can also become infected.

Each infectious disease has its own specific signs and symptoms. General signs and symptoms common to a number of infectious diseases include:

  • Fever
  • Diarrhea
  • Fatigue
  • Muscle aches
  • Coughing
