Biology - Control

Control

The 1918-19 Influenza pandemic: masks were used to limit the spread of
the disease.

In some populations of organisms, some diseases are endemic [1], forming a
reservoir for the particular pathogen. Under conditions favourable to the
pathogen, the disease could develop and spread rapidly within the host
population to become an epidemic. If a disease becomes worldwide, as did
the flu in 1918/19 and 1957, it is called a pandemic. Whole crops can be
wiped out by fungi; for example, the potato famine in Ireland caused
devastation of wheat crops by rusts.

If the method of transmission is known, it may be possible to control or
prevent the spread of the pathogen or parasite, depending on the scale of
the infection. Methods of control include:

* improved hygiene and food handling practices

* care when sneezing or coughing

* appropriate sewage disposal

* removal of vectors

* application of antiseptics and disinfectants

* breaking the life cycle of pathogenic parasites

* changing the environmental conditions in which pathogens, parasites or
their vectors flourish (including the reservoir)

* use of chemical control, for example pesticides, fungicides, etc.

* biological control; that is, finding a specific natural predator

* quarantine or isolation
