- A short and sharp course of diseases; not chronic.
- Molecules produced by B cells in response to specific proteins (antigens)
carried by infected cells. Antibodies are directed against specific infections
and help fight the disease.
- A protein "recognized" by the body as being foreign; it results in the production
of specific antibodies directed against it.
- Without symptoms. Many illnesses begin with a period during which
there are no symptoms.
- B cells
- A specific kind of white blood cell that produces antibodies.
- Bacillus, bacilli (pl)
- Rod shaped bacteria.
- Bacterium, bacteria (plural)
- A microscopic one celled organism. Some bacteria are
essential for our survival and others may cause disease.
- Of long duration, denoting a disease of slow progress and long duration.
- Spherical shaped bacteria.
- The period of recovery.
- Diarrhoeal diseases
- Infections that cause severe diarrhoea, mainly spread by
contaminated food or water; can cause death by severe dehydration.
- Respiratory disease transmitted by droplet and airborne transmission. Can
interfere with swallowing; if not treated can result in heart disease or
- Droplet infection
- Infection caused by inhaling tiny droplets of moisture from the cough
or sneeze of an infected person which contain viruses or other pathogens.
- A disease that is always present in a community.
- Occurrence in the community or region of a group of illnesses (or an
outbreak) of similar nature, obviously in excess of normal expectancy and
derived from a common or propagated source.
- The study of the incidence, distribution and
determinants of an infection, disease or other
health-related event in a population. Epidemiology can
be thought of in terms of who, where, when, what, and
why. That is, who has the infection/disease, where are
they located geographically and in relation to each
other, when is the infection/disease occurring, what is
the cause, and why did it occur.
- Resistance to a specific disease.
- The act of inducing antibody formation leading to immunity.
The inability of the immune system to
satisfactorily protect the body, which results in an
increased susceptibility to various cancers and
- The frequency of new infections during a
designated time period expressed.
- Incubation period
- The period of time after exposure to a disease that it takes for the
host to display symptoms of that disease.
- Infectious period
- The period of time during which an ill person may pass their disease
- A chemical that kills insects.
- A hazy feeling of not being well.
- Opportunistic infection
- An infection caused by a microbe which a healthy person
would be able to fight off. Opportunistic infections are found in
immunodeficient persons, those suffering form AIDS, an those on chemo
- A disease attacking or affecting all. Larger than an epidemic.
- An organism living on or in another organism called host. The parasite
obtains its food from the host resulting in damage to the host.
- A sudden onset of a symptom or disease.
- An microbe, such as virus or bacteria, which may cause disease.
- A WHO and UNICEF- supported project dedicated to stamping out polio
worldwide by the year 2000. It is also supported by NGOs, such as the
Rotary Clubs International, and by governments, such as those of
Australia, Canada and the United States of America.
- Number of events present at a given point in time.
- Protozoan, protozoa
- A simple one-celled microorganism that can cause an infection.
- Spiral shaped bacteria.
- Surveillance program
- A deliberate continuous effort by an agency to monitor the
occurrence, prevalence and development of a particular disease.
- T cells
- A specific kind of white blood cell, active in controlling the immune response
and attacking infections.
- Administration of a vaccine.
- A preparation made from killed or weakened pathogens which when
introduced in the body induce the production of antibodies and thus
boost the body's immunity against that pathogen.
- An agent, usually an animal or an insect, that transmits a pathogen form one
host to another.
- An infectious agent made of protein and genetic material. It is not made of a cell
and must invade another cell to reproduce.
- White blood cell
- Blood cells which are provide the body with its principle line of defense
