Infectious Diseases

What is an infectious disease?

Infectious diseases can range from common illnesses such as the cold, to serious illnesses such as meningitis or AIDS. According to the Centers for Disease Control and Prevention (CDC), an infectious disease is caused by one or more of the following: 

  • Viruses
  • Bacteria  
  • Parasites 
  • Fungi  

What causes infectious diseases?

Depending on the disease-causing organism, an infection can spread in some or all of the following ways: 

  • Airborne transmission: transmission of an infection through inhaling airborne droplets of the disease, which may exist in the air as a result of a cough or sneeze from an infected person
  • Blood-borne transmission: transmission of an infection through contact with infected blood, such as when sharing hypodermic needles
  • Direct skin contact: transmission of an infection through contact with the skin of an infected person
  • Insect-borne transmission: transmission of an infection through insects such as mosquitoes that draw blood from an infected person and then bite a healthy person
  • Food-borne transmission: transmission of an infection through consuming contaminated food 
  • Water-borne transmission: transmission of an infection through contact with contaminated water
  • Sexual transmission: transmission of an infection through sexual contact, including intercourse

How do doctors at Children's Hospital Colorado make a diagnosis?

Our infectious disease specialists work closely with referring doctors to diagnose and treat conditions.

Typically patients are referred by their primary care doctors or pediatricians. To help diagnose your child's symptoms, our specialists may need to conduct routine tests, such as blood samples.

How do antibiotics work against infections?

Antibiotics can be used to treat bacterial infections. It is important that antibiotics are taken properly and for the duration of the prescription. Antibiotics are ineffective in treating virus-related illnesses.

Overuse or misuse of antibiotics can lead to drug-resistant bacteria.
