Enzootic<br />

enzootic infections are present all the time in animals of a specific geographic<br />

area<br />

Epidemic<br />

epidemic infections are those that spread rapidly in a community; measles and<br />

influenza viruses are common causes of epidemics in Australia; small epidemics<br />

are often called outbreaks<br />

Extensive limb swelling<br />

swelling of the limb, with or without redness, which:<br />

» extends from the joint above to the joint below the injection site, or beyond<br />

a joint (above or below the injection site), or<br />

» results in the circumference of the limb being twice the normal size.<br />

Febrile<br />

related to a fever, as in febrile illness and febrile convulsions<br />

Hepatitis<br />

an inflammation of the liver; can be caused by viral infections<br />

Hypotonic-hyporesponsive episode (shock, collapse)<br />

the sudden onset of pallor or cyanosis, limpness (muscle hypotonia), and<br />

reduced responsiveness or unresponsiveness occurring after vaccination,<br />

where no other cause is evident, such as a vasovagal episode or anaphylaxis.<br />

<strong>The</strong> episode usually occurs 1 to 48 hours after vaccination and resolves<br />

spontaneously.<br />

<strong>Immunisation</strong><br />

the process of inducing immunity to an infectious agent by administering a<br />

vaccine<br />

Immunity<br />

the ability of the body to fight off certain infections; immunity can result from<br />

natural (‘wild’) infections or from vaccination<br />

Immunogenicity<br />

the ability (or the degree) to which a particular substance, in this context a<br />

vaccine, may provoke an immune response<br />

Immunoglobulin<br />

a protein extract from blood, sometimes called ‘antibody’, that fights off infection;<br />

injection of immunoglobulins provides temporary immunity against certain<br />

infections<br />
