Clinical Information

  • TRAVEL RELATED ILLNESS-. health problems associated with travel.
  • COMMUNICABLE DISEASES IMPORTED-. infectious diseases originating in one geographically delineated ecosystem that are carried by travel or immigration to another geographically delineated ecosystem by an infected individual animal or disease vector.
  • COMMUNICABLE DISEASES-. an illness caused by an infectious agent or its toxins that occurs through the direct or indirect transmission of the infectious agent or its products from an infected individual or via an animal vector or the inanimate environment to a susceptible animal or human host.
  • DISEASE OUTBREAKS-. sudden increase in the incidence of a disease. the concept includes epidemics and pandemics.
  • DISEASE RESERVOIRS-. animate or inanimate sources which normally harbor disease causing organisms and thus serve as potential sources of disease outbreaks. reservoirs are distinguished from vectors disease vectors and carriers which are agents of disease transmission rather than continuing sources of potential disease outbreaks.
  • DISEASE VECTORS-. invertebrates or non human vertebrates which transmit infective organisms from one host to another.
  • ZOONOSES-. diseases of non human animals that may be transmitted to humans or may be transmitted from humans to non human animals.
  • CONTACT TRACING-. identification of those persons or animals who have had such an association with an infected person animal or contaminated environment as to have had the opportunity to acquire the infection. contact tracing is a generally accepted method for the control of sexually transmitted diseases.
  • INFECTIOUS DISEASE TRANSMISSION PROFESSIONAL TO PATIENT-. the transmission of infectious disease or pathogens from health professional or health care worker to patients. it includes transmission via direct or indirect exposure to bacterial fungal parasitic or viral agents.
  • INFECTIOUS DISEASE TRANSMISSION PATIENT TO PROFESSIONAL-. the transmission of infectious disease or pathogens from patients to health professionals or health care workers. it includes transmission via direct or indirect exposure to bacterial fungal parasitic or viral agents.
  • INFECTIOUS DISEASE TRANSMISSION VERTICAL-. the transmission of infectious disease or pathogens from one generation to another. it includes transmission in utero or intrapartum by exposure to blood and secretions and postpartum exposure via breastfeeding.
  • DISEASE TRANSMISSION INFECTIOUS-. the transmission of infectious disease or pathogens. when transmission is within the same species the mode can be horizontal or vertical infectious disease transmission vertical.
  • DISEASE NOTIFICATION-. notification or reporting by a physician or other health care provider of the occurrence of specified contagious diseases such as tuberculosis and hiv infections to designated public health agencies. the united states system of reporting notifiable diseases evolved from the quarantine act of 1878 which authorized the us public health service to collect morbidity data on cholera smallpox and yellow fever; each state in the us has its own list of notifiable diseases and depends largely on reporting by the individual health care provider. from segen dictionary of modern medicine 1992
  • COMMUNICABLE DISEASES EMERGING-. infectious diseases that are novel in their outbreak ranges geographic and host or transmission mode.
  • INFECTIOUS DISEASE INCUBATION PERIOD-. the amount time between exposure to an infectious agent and becoming symptomatic.
  • INFECTIOUS DISEASE MEDICINE-. a branch of internal medicine concerned with the diagnosis and treatment of infectious diseases.

Information for Patients


Infectious Diseases

Germs, or microbes, are found everywhere - in the air, soil, and water. There are also germs on your skin and in your body. Many of them are harmless, and some can even be helpful. But some of them can make you sick. Infectious diseases are diseases that are caused by germs.

There are many different ways that you can get an infectious disease:

  • Through direct contact with a person who is sick. This includes kissing, touching, sneezing, coughing, and sexual contact. Pregnant mothers can also pass some germs along to their babies.
  • Through indirect contact, when you touch something that has germs on it. For example, you could get germs if someone who is sick touched a door handle, and then you touch it.
  • Through insect or animal bites
  • Through contaminated food, water, soil, or plants

There are four main kinds of germs:

  • Bacteria - one-celled germs that multiply quickly. They may give off toxins, which are harmful chemicals that can make you sick. Strep throat and urinary tract infections are common bacterial infections.
  • Viruses - tiny capsules that contain genetic material. They invade your cells so that they can multiply. This can kill, damage, or change the cells and make you sick. Viral infections include HIV/AIDS and the common cold.
  • Fungi - primitive plant-like organisms such as mushrooms, mold, mildew, and yeasts. Athlete's foot is a common fungal infection.
  • Parasites - animals or plants that survive by living on or in other living things. Malaria is an infection caused by a parasite.

Infectious diseases can cause many different symptoms. Some are so mild that you may not even notice any symptoms, while others can be life-threatening. There are treatments for some infectious diseases, but for others, such as some viruses, you can only treat your symptoms. You can take steps to prevent many infectious diseases:

  • Get vaccinated
  • Wash your hands often
  • Pay attention to food safety
  • Avoid contact with wild animals
  • Practice safe sex
  • Don't share items such as toothbrushes, combs, and straws
